First Tornado of 2024 Confirmed in Ontario on March 16th; Ties With Earliest Tornado on Record

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

In an unusually early start to the tornado season, Ontario recorded its first confirmed tornado of the year on March 16th. This event ties with the record for the earliest tornado occurrence in the province, a record previously set in 2016 in Clifford, Ontario.

The Northern Tornadoes Project (NTP) confirmed the tornado following a comprehensive damage survey in the Malden Centre area, south of Windsor, where significant damage was reported.

Rated as an EF1 on the Enhanced Fujita Scale, the tornado reached maximum wind speeds of about 150 km/h. The most significant damage was noted where a double-wide mobile home had its roof completely removed. Other damages included shingle destruction, a downed tree at another residence, and extensive damage to trees in surrounding woodlands.

The rotation is apparent only in the two lowest tilts (second tilt not shown).

Classified as a QLCS (Quasi-Linear Convective System) tornado, it developed along the leading edge of a thunderstorm's outflow. Radar data from Detroit Metro Airport clearly showed a tight rotation at the exact locations of the reported damages. There were no preceding tornado warnings and no reports of severe weather from nearby Michigan, although the storm did produce severe hail in parts of Ontario.

The tornado's path was approximately 1.10 kilometres long and reached a maximum width of 100 meters. The damage to trees was presumably less severe than it might have been if the trees had been in leaf, which could have resulted in more extensive damage.

The Countdown is On! One Week Until Solar Eclipse in Ontario

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE


Ontario is in for a rare celestial display of a solar eclipse on Monday, April 8, 2024. The entire province will be able to witness this, and small stretch of Southern Ontario will be treated to a very brief total solar eclipse with a “ring of fire” as the Moon moves across and obscures the Sun.

Here's what you need to know about this event and how to observe it safely.

Timing and Coverage

Residents across Northern Ontario will see at least 50% of total sun coverage, with the Northwestern edge of the province seeing the least and coverage gradually increases moving south and east to just under 90% once reaching Southern Ontario.

This will be a spectacular partial eclipse for Northern Ontario, but Southern Ontario is in for a real treat. The whole region will see more than 90% of the Sun covered by the Moon. However, along most the northern shores of Lake Erie and Lake Ontario, as well as in the Niagara Region, up into the northern edges of both Norfolk and Haldimand Counties, into the southern extent of Brant County to Hamilton and even around Burlington Bay to include the City of Burlington, residents and visitors will be able to witness a full solar eclipse for a couple short minutes.

Unfortunately, the most heavily populated area of the Lake Ontario lakeshore, from Oakville across the City of Toronto to Bowmanville, will be just outside of the path of totality.

Safety Measures

Safety is paramount when viewing any solar eclipse, even a partial one. To ensure a safe and memorable experience, follow these crucial precautions:

  • Solar Viewing Glasses: Never attempt to observe the eclipse with the naked eye. Only use certified solar viewing glasses or eclipse glasses with ISO 12312-2 certification, specifically designed to protect your eyes from the Sun's harmful radiation.

  • Pinhole Projection: If eclipse glasses are unavailable, create a pinhole projector using common materials like cardboard. This indirect method allows you to project the eclipse safely onto a surface for viewing.

  • Telescopes and Binoculars: If using telescopes or binoculars, ensure they are equipped with proper solar filters to safeguard your eyes. Never aim them directly at the Sun without these protective measures.

  • Online Streaming: For those unable to view the eclipse in person or seeking a risk-free option, numerous reputable sources will provide live streaming of the event.

  • Local Eclipse Events: Consider joining local astronomy clubs or observatories hosting eclipse-viewing gatherings. These events offer expert guidance and a shared sense of community.

Please note that cloud cover could affect the ability to see the eclipse. Cloud cover is historically 60-80% for early April so be prepared for variable weather conditions and have alternative viewing options available.

Ontario is in for a celestial treat as we prepare to witness a partial view of the annular solar eclipse on Saturday, October 14, 2023. While not the full "ring of fire" experience seen in some parts of the world, this partial eclipse promises a captivating display of the Moon partially obscuring the Sun's disk.

This partial solar eclipse is an appetizer for our region as we look forward to a total solar eclipse that will be visible in parts of Southern Ontario on April 8, 2024. Which is less than 6 months away!

Here's what you need to know about this event and how to observe it safely.

Safety Measures

Safety is paramount when viewing any solar eclipse, even a partial one. To ensure a safe and memorable experience, follow these crucial precautions:

  • Solar Viewing Glasses: Never attempt to observe the eclipse with the naked eye. Only use certified solar viewing glasses or eclipse glasses with ISO 12312-2 certification, specifically designed to protect your eyes from the Sun's harmful radiation.

  • Pinhole Projection: If eclipse glasses are unavailable, create a pinhole projector using common materials like cardboard. This indirect method allows you to project the eclipse safely onto a surface for viewing.

  • Telescopes and Binoculars: If using telescopes or binoculars, ensure they are equipped with proper solar filters to safeguard your eyes. Never aim them directly at the Sun without these protective measures.

  • Online Streaming: For those unable to view the eclipse in person or seeking a risk-free option, numerous reputable sources will provide live streaming of the event.

  • Local Eclipse Events: Consider joining local astronomy clubs or observatories hosting eclipse-viewing gatherings. These events offer expert guidance and a shared sense of community.

Northern Lights Dazzle the Sky Over Southern Ontario on Monday Night; Will They Return Tonight?


GOOGLE AD (NOT ENDORSED BY INSTANT WEATHER)

Residents across Southern Ontario were treated to a rare and awe-inspiring celestial spectacle last night, as the Northern Lights made a stunning appearance across the region on Monday. The breathtaking natural light show painted the night sky with vibrant hues of green, pink, and purple.

The Northern Lights, also known as the Aurora Borealis, are a natural phenomenon caused by charged particles from the sun colliding with gases in the Earth's atmosphere. This collision releases energy in the form of colourful light, creating an ethereal dance of colours that is a sight to behold. While the Northern Lights are more commonly associated with regions closer to the Arctic Circle, the display seen in Southern Ontario was a rare treat for residents in this part of Canada.


GOOGLE AD (NOT ENDORSED BY INSTANT WEATHER)

Those across the province were quick to capture the event, sharing stunning photographs and videos on social media. This was certainly the case in our weather report group, Ontario Storm Reports as we received over 200 pictures of the dazzling colours!

During last night's Northern Lights display in Southern Ontario, a fascinating celestial guest made an appearance alongside the traditional Aurora Borealis: STEVE, or Strong Thermal Emission Velocity Enhancement. This mysterious phenomenon, often likened to a "picket fence" of light, added an extra layer of intrigue to the already mesmerizing light show.


GOOGLE AD (NOT ENDORSED BY INSTANT WEATHER)

STEVE is not a true aurora but rather a separate atmospheric phenomenon, and its presence in the Southern Ontario night sky last night added to the wonder and mystique of the celestial spectacle, leaving observers in awe of the captivating dance of light above.

Predicting the visibility of the Northern Lights, or Aurora Borealis, in Southern Ontario involves monitoring the geomagnetic activity, often assessed using the Kp Index. Last night, with a Kp Index around 6-7, conditions were favourable for the auroras to grace the skies of Southern Ontario.

MAP FROM noaa swpc

To be able to see the Northern Lights, we require a Kp Index of at least 5 for the northern section of Southern Ontario and around 6 for the rest of Southern Ontario. A Kp Index of 3-4 means that the Aurora will likely be relegated to the far northern part of Northern Ontario where it is more commonly found.

After last night’s impressive display of colours, many have wondered if the Northern Lights will return for an encore performance on Tuesday night. Unfortunately, the latest data isn’t favourable for the Northern Lights to be viewable in Southern Ontario. The Space Weather Prediction Center is forecasting a maximum Kp Index of 4 over the next 12 hours.


GOOGLE AD (NOT ENDORSED BY INSTANT WEATHER)

With a Kp Index of 4, we could see the Northern Lights be visible as far south as Winnipeg and Thunder Bay. The chances of the Aurora reaching as far south as Southern Ontario are low. However, we can’t rule out the Auroras being visible along the horizon in northern parts of the region.

While this level is not as conducive to the Northern Lights as last night's conditions, it's essential to remember that aurora forecasting can be somewhat unpredictable. Nature has its way of surprising us, and sometimes, even with a lower Kp Index, the Northern Lights might still put on a show.

Windsor’s Third Tornado of 2023 Ties It With Ottawa in a Contest That Neither City Wants to Win

IMAGE COURTESY OF THE NORTHERN TORNADOES PROJECT (NTP)

The NTP has confirmed that Windsor’s third tornado of the season touched down at 10:30 PM on Thursday, August 24th, 2023. NTP’s damage investigation revealed that the tornado was on the ground for 11.6 kilometres and had a maximum width of 470 metres. The estimated maximum wind speed was 125 km/h, which classifies this tornado as an upper-end EF0 and only 10km/h shy of a low-end EF1. They also estimate the forward-motion of the tornado was 80km/h.

We at Instant Weather sent out a “TORNADO POTENTIAL” notification at 10:18 PM that specifically mentions Windsor, 12 minutes in advance of the tornado (https://instantweather.ca/2023/08/25/TN5azD-tornado-potential/) during our livestream (https://www.youtube.com/live/tvNR6bM37S0&t=9053).

IMAGE COURTESY OF THE NORTHERN TORNADOES PROJECT (NTP)

Environment Canada issued a Tornado Warning for Essex County at 10:36 PM, 6 minutes after the tornado began and unfortunately, it did not mention Windsor was in the path; “Locations impacted include: Amherstburg, LaSalle, McGregor, Colchester and Harrow.” (https://instantweather.ca/2023/08/25/GAadqr-tornado-warning-replaces-severe-thunderstorm-warning/).

IMAGE COURTESY OF THE NORTHERN TORNADOES PROJECT (NTP)

Environment Canada did, however, forecast a "High Risk” for severe weather that included the risk for a tornado at 11:29 AM (https://twitter.com/ECCCWeatherON/status/1694733744320487555) along with mentioning a risk of a tornado in their Severe Thunderstorm Watch (https://instantweather.ca/2023/08/24/ZysJ2g-severe-thunderstorm-watch-issued/). Additionally, Environment Canada issued a Severe Thunderstorm Warning for Essex County at 9:34pm (https://instantweather.ca/2023/08/25/lrF3yo-severe-thunderstorm-warning-issued/). However, it had no mention of a tornado risk.

A huge thank you to our passionate community for helping us get the word out about tornadoes and severe weather! Our thoughts remain with all those affected by Thursday’s storms.

EF0 Tornado Confirmed South of Hamilton, Ontario on Saturday Morning

The Northern Tornadoes Project (NTP) has officially verified the occurrence of a tornado near Caledonia, Ontario, during the morning hours of Saturday (August 12, 2023, at 10:15 AM EDT). The tornado's impact resulted in EF0 damage, primarily affecting trees within the vicinity.



The visual evidence captured by witnesses, including images and videos of the funnel cloud, prompted the NTP to launch an investigation into the event. Their findings unveiled a narrow path of damage situated to the northeast of Caledonia. This affected area showcased characteristics of snapped stems and broken branches, along with indications that the tornado had lifted larger branches.



In terms of intensity, the tornado's maximum wind speed was estimated at 115 km/h. It followed a track length of 5 kilometres, with its maximum path width spanning 150 meters.

This radar scan at 9:59 AM from the King City radar as shown on IW Pro provided an early indication of potential tornado activity to the northwest of Caledonia. This rotation eventually materialized into the confirmed tornado, which touched down approximately 15 minutes later northeast of Caledonia.



Based on the radar-detected rotation, Instant Weather sent out a ‘Tornado Potential’ notification at 9:53 AM. This advance notification specifically identified Caledonia as an area potentially at risk where the tornado eventually touched down around 20 minutes later:

We've detected tornado potential with this storm near #Middleport, tracking east towards the #Caledonia and #MountHope region. Significant damaging winds are present on radar as well.

Tornado potential means this storm could produce an isolated tornado.

Environment Canada issued a severe thunderstorm warning at 10:18 AM which included Caledonia, however, it didn’t mention any tornado risk.

Fireball Lights Up the Sky on July 26 2022

Credit Image from SOMN

Did you see a fireball on July 26, 2022 at approximately 9:27pm? Perhaps you unknowingly captured it on a security camera. Team member Liam M. from Hamilton was lucky enough to spot it.

About 100 reports (to date) of this fireball have been submitted to American Meteor Society from observers in Ontario and the US. Below is the current map of the observers from the American Meteor Society event page.

The Southern Ontario Meteor Network (SOMN) observed the fireball on 8 all sky cameras. This enabled SOMN to analyze the data that they collected and they determined that the meteor became visible at 77 kilometer above King City and it was moving south at 79,200 km per hour. It decended at a sharp angle of 70 degrees before it disintegrated 34 kilometers above the intersection of the 400 and 427 in Toronto. They esimate that this asteroidal fragment weighed 11 kg and had a diamter of 20 cm. It was as bright as a waxing crescent Moon. See NASA Meteor Watch post.

A dashcam video of the fireball was also posted on reddit.

You can report fireball observations (and also send in videos and pictures if you have them) to the American Meteor Society (AMS) or it’s partner the International Meteor Organization (IMO). The reports not only alert them to potentially scientifically significant events, they also add to the database of knowledge about meteors.

Southern Ontario: Storm Summary for Thursday, February 17 to Friday, February 18, 2022

A snowstorm brought accumulating snowfall to much of Southern Ontario between Thursday and Friday. As part of Instant Weather’s commitment to accountability and transparency, we collected reports from our community after the storm. Thank you to everyone who submitted their report to us!

We also utilized CoCoRaHS which contains an extensive database of reported snowfall totals from all over Southern Ontario. Between the two data sources, we were able to obtain snowfall reports from many locations across the region to compare to our custom forecast. In the case that we received multiple snowfall reports for a single location, these totals were averaged together to calculate an aggregate total for that location.

With this storm, our forecast (LINK) had the potential for widespread snowfall accumulation ranging from 15-30cm with a lower amount towards the Niagara region and Central Ontario. Learning from the previous storm earlier this month, we made changes to our approach to forecasting storms like this one where temperatures are closer to the freezing mark. This tried to account for the tendency for these events to underperform the snowfall totals suggested by models due to mixing and lower snow ratios. While model data at the time showed widespread 20-30cm and even some pockets of 35cm, we went with 15-30cm and locally 30+cm. This accounted for the mixing potential while not ignoring what models were showing in case it was correct (as what happened with the January blizzard).

Based on the data, it looks like the underperformance did occur as general totals were closer to the 10-20cm range with localized pockets of 20-25cm. As a result, many areas received snowfall totals that were towards the lower end of our forecast range, but most areas were still within our range. The main area of inaccuracy in our forecast was through Deep Southwestern Ontario including Windsor and London since they saw a more prolonged period of freezing rain than expected. So Windsor for example didn’t even reach the 10cm mark in most reports that we received.

We correctly forecasted around 72% of locations while no locations reached our ‘local’ range since this event didn’t overperform. Another 24% of locations were within 5cm of our forecast range mainly in Southwestern Ontario and the GTA. Overall, the error in our forecast was 1.1cm. It does seem like our approach to changing how we forecast events with mixing has worked as our accuracy rate is above 70% despite the underperformance.

Southern Ontario: Storm Summary for Wednesday, February 2 to Friday, February 4, 2022

A multi-day snowstorm affected much of Southern Ontario last week between Wednesday and Friday. As part of Instant Weather’s commitment to accountability and transparency, we collected reports from our community after each wave. Thank you to everyone who submitted their report to us!

We also utilized CoCoRaHS which contains an extensive database of reported snowfall totals from all over Southern Ontario. Between the two data sources, we were able to obtain snowfall reports from many locations across the region to compare to our custom forecast for each wave. In the case that we received multiple snowfall reports for a single location, these totals were averaged together to calculate an aggregate total for that location.

Starting with the first wave of the storm which includes snowfall received between Wednesday (Feb. 2) and Thursday (Feb. 3) morning. Our forecast (HERE) had widespread 15-25cm across much of Southwestern and Central Ontario with a localized zone of 20-30cm in Deep Southwestern Ontario.

Based on the data, it’s clear that the system underperformed compared to our forecast with only a handful of locations picking up over 20cm. This is particularly the case in Southwestern Ontario where locations such as Windsor, Chatham-Kent, Sarnia and London had to potential to pick up 20-30cm, but only received around 10-15cm from the first wave. This underperformance is also seen throughout the Golden Horseshoe where most locations in the GTA and Hamilton region reported around 5-10cm. Central Ontario was a bit better where most locations were within or very close to our forecast range, especially in the Muskoka and Kawartha Lakes region.

Why did this first round underperform? We had fairly good confidence based on the data, however, the major issue was the temperature which didn’t fall quite as fast as we expected. This meant that most locations in the south and around Lake Ontario saw a more prolonged period of rain or wet snow before transitioning over to regular accumulating snow. The snow that did fall ended up being wetter which has a harder time to accumulate so totals in the aforementioned regions were significantly cut down. Moving forward, we will be more careful of forecasting higher snowfall totals with the temperature near the freezing mark as the simulated totals don’t account for any melting.

When comparing the data to our forecast, we correctly forecasted around 20% of locations mostly in Central Ontario. This is not up to our standards and we will work towards tweaking our approach as mentioned. The slight underperformance in most areas is seen in the 42% of locations that were within 5cm of our forecast range. Around 25% of locations were off by more than 5cm which is mostly for those in Deep Southwestern Ontario that saw more mixing and a slower switch over. Overall, the error in our forecast was 4.6cm.

Southern Ontario also received a second round of snow between Thursday (Feb. 3) afternoon and Friday (Feb. 4). As per our final forecast (HERE) for the second wave, we indicated that it would miss much of our region and mainly affect the Niagara region and Extreme Southeastern Ontario.

Based on the data it appears that this indeed was the case with most areas reporting less than 10cm except for those along the Lake Erie shoreline. An important disclaimer to this data is that we were unable to obtain reports for what we believe are the hardest-hit regions through the Niagara region and into Brockville/Cornwall. We also heavily relied on observations from CoCoRaHS as we only received a handful of reports from our community. Between the two sources, we were still able to estimate totals for 49 different locations.

Our forecast for the second wave compared to the collected data shows that it performed a lot better compared to the first wave. Just under 80% of locations were within our forecast range with a slight overperformance so another 12% were within our local range. The average error in the forecasted snowfall totals from our forecast was 0.7cm.
