7:54 AM - Wed, Dec 9, 2020: Snow and rain continues across parts of our region. Personally, my area of Barrie got a few cm of snow. ... What did you get? - Adam

Did you get the AlertReady test on your phone, TV, etc? To clarify, we have absolutely nothing to do with that test. Just curious if you received it. And no, it won't be on our app. :) - Adam

Three fireballs have been spotted in Ontario during the past week. Did you see any of them? Did you know that you can report your observations of fireballs to the International Meteor Organization or the American Meteor Society and help researchers? Please see the link below for video and more details including which one exploded causing a shock wave that produced a sonic boom and was measured on seismic instruments: https://instantweather.ca//fireballs-light-up-ontario-skie

Did you see one or both of the fireballs reported Monday evening? One was spotted around 7:30 pm (preliminary path travelling NW over Brockville, ON). The second one was seen at around 8:30 pm (preliminary path travelling WNW south of Syracuse, NY). - Teresa K.

Our thoughts are with those affected by the erosion happening on Lake Erie and any other areas with these issues. https://twitter.com/craigdunmore/status/1335698793296240642

SOUTHERN ONTARIO SNOW SQUALL UPDATE VALID: Tuesday, Nov 17th, 2020 Good early morning everyone!... Just a quick update and forecast map for the snow squalls that are expected to develop Tuesday morning and continue throughout the day southeast of Georgian Bay and Lake Huron. We're already seeing some lake effect snow activity off Georgian Bay through northern Simcoe County and that will further strengthen through the night. This band will continue to bring accumulating snowfall to this small zone from Midland to Orillia with the potential for as much 10-15cm of accumulation. We expect the squall to sink southward late in the morning and could bring a few hours of heavy snow to as far south as Barrie and Bradford just before noon. The higher elevations south of Collingwood like the Blue Mountains may also see this as well as. Total accumulation here will range from 2-6cm with locally up to 10cm. Turning to Lake Huron, a fairly strong squall is expected to develop with a northwest flow either during the late morning or early afternoon. This will bring intense near-zero visibility and rapidly accumulating snowfall to regions around Kincardine and Goderich. The squall will occasionally shift around throughout the afternoon and evening so that should help spread around the accumulation rather than having one focused zone of extreme accumulation. We expect that the lake effect activity will come to an end overnight and early Wednesday morning. The hardest-hit zone includes Wingham and Clinton with the potential to pick up as much as 12-20cm by Wednesday morning. Surrounding areas can expect between 5-15cm - refer to the map for more location-specific details. Be sure to drive according to the conditions if you plan on travelling in the affected regions! Conditions can go from clear to a complete white-out in a matter of seconds so you will need to be able to adjust quickly. - Brennen P.

Just a heads up that the Alert Ready system will be tested in just under an hour at 12:55 PM. This means you’ll receive an emergency test alert on your phone along with on radio and TV. Don’t panic! It’s just a test :)... - Brennen P.

7:21 AM - Wed, Nov 25, 2020: Blue = snow Purple = freezing rain / mixing Green = rain ... I = yawning What are you experiencing? - Adam

Plunge Into Winter After Record-Breaking Wind Storm; Snow Squalls East of Georgian Bay & Lake Huron to Bring Up to 15cm on Monday Valid: Monday, November 16th, 2020 Full forecast: https://instantweatherinc.com//plunge-into-winter-after-re... Squalls could redevelop again Tuesday morning but will affect regions south of Georgian Bay and northeast of Lake Huron (Kincardine, Owen Sound etc.). We’ll continue to monitor that and issue a forecast if necessary. - Brennen P.

Sorry in advance... The First Snowfall Possible Saturday Morning for Parts of Southern Ontario As the Season’s First Snowstorm Takes Aim at Northern Ontario This Weekend Full forecast here: https://instantweatherinc.com//the-first-snowfall-possible... - Brennen P.

Hi! How are we doing tonight? After a fairly mild day which likely melted a lot of the snow that we received yesterday and early this morning, the temperatures are heading back to below the freezing mark. Overnight lows will range from -4 to -8C so all that melted snow and moisture will likely refreeze on untreated surfaces. Expect some icy road and sidewalk conditions into tomorrow morning. It shouldn't be a major issue but just be careful out there if you're travelling ar...ound. Besides that, our eyes turn towards a system that could bring another round of accumulating snowfall and messy weather to Southern Ontario starting late Tuesday and lasting into Wednesday. At this point, it doesn't appear to be a major storm with maybe as much as 6-12cm of accumulation through parts of Central and Eastern Ontario. Temperatures should remain just warm enough for Southwestern Ontario and the Golden Horseshoe to start off with wet snow but quickly turning over to heavy rainfall overnight into Wednesday. By Wednesday afternoon, all of Southern Ontario should have transitioned over to heavy rain which will continue into Thursday. Total rainfall accumulation between 10-25mm looks possible by the end of Thursday. We'll have a full forecast including accumulation and timing out very soon either late tonight or sometime tomorrow. Stay tuned! - Brennen P.

Okay, who ordered the snow? Big fluffy flakes coming down in Bracebridge, Ontario this afternoon. Even starting to see some accumulation and wet slush on the ground. Are you seeing any snow today? Looks like a portion of Central and Eastern Ontario will see their first snowfall of the season today, but accumulation will be minor if any at all.... - Brennen P.

Storm Discussion & Exciting App News! (Fri, Oct 16, 2020) Watching for some strong wind gusts along Lake Huron with the storms moving in this afternoon and especially later this evening. There's a marginal (low) risk for some isolated damaging wind gusts with these storms so we'll be watching closely for isolated power outages and reports of limbs and perhaps some weak or dead trees could come down.... Questionable if the wind gusts will reach the severe threshold of 90km/h but they may come close and could cause a bit of wind damage. Huge thank you to those who send us stars, which are $0.01 each. We really appreciate your support and thank you to those who use and promote our free app InstantWeather! InstantWeatherApp.com Be safe folks! - Adam

Over 210k Hydro One customers are without power at ths hour as of 5:15 PM. That’s over 15% of Ontario who are served by Hydro One without power And the number keeps climbing with every update. This is going to be a long night for many. Stay warm! - Brennen P.

VALID: 12:24AM - Monday, October 26, 2020 Do I see blue on the radar? Yes, it looks like flurries are occurring throughout parts of Northern Muskoka into the Algonquin Park area tonight. Also seeing some scattered flurries around the higher elevations through Orangeville and Chatsworth.... Not expecting much in regards to accumulation but don’t be surprised if you wake up with a dusting of s*** on your yard in the morning. Even into parts of Eastern Ontario and maybe the Ottawa region! - Brennen P.

Many have been asking us on when the wind storm will end. The good news is that for most regions the worst is behind us - this is except for the Kingston and Prince Edward County area which are just seeing the winds pick up. Damaging wind gusts occasionally reaching 85-100km/h inland and 100-120km/h along the shorelines will continue for several more hours throughout Southern Ontario. We’ll begin to see the winds ease around midnight for most areas. Although strong winds wil...l linger into Monday morning ranging from 60-80km/h (areas along the shoreline may still see a few 90km/h gusts). It will finally end by sunrise tomorrow morning. We hope you all are staying safe this evening! - Brennen P.

INCREDIBLE Video of What Appears to Be a Tornado From Thornbury, Ontario During Friday’s Storm: Video of what appears to be a tornado, filmed by Kim H.G. from Thornbury as it moved northeast over Georgian Bay on Friday, Oct 23, 2020. In our option, this appears to be a tornado based on the rotating wall cloud above, the trailing rear-inflow jet or ghost train, the strong rotation evident on radar, and the fact that #Thornbury residents have reported significant damage from ...this storm. Also, if you turn up the volume, there’s quite the howl. This is simply our opinion and thankfully, the NTP and Environment Canada are currently investigating the damage and we’ll let you know what the results of their survey are ASAP. Our thoughts are with those affected by Friday’s storms. - Adam P.S. Big thanks to Justin M. @justinmweather for bringing this video to everyone’s attention on Twitter. P.P.S.

11:55 AM - Thu, Oct 15, 2020: Rain continues to slowly push across the region in green (light rain) and yellow (heavy rain). Occasional lightning isn’t completely out of the question and it’s pretty gusty out there for some of us.... What are you experiencing? - Adam

7:37 PM - Mon, Oct 12, 2020: Happy Thanksgiving to all those who celebrate it! Line of heavy rain , lightning , and gusty winds are moving in overnight.

Wainfleet, 5 minutes from lake Erie a wind gust ripped one of our open outer windows off, crossed through our bedroom and tore our bedroom door off the hinges. Anyone else in the area experience wind damage? Please let us know and we hope everyone stayed safe!... - Adam

Yesterday was pretty crazy! We hope everyone stayed safe. Of course, one of the most active events of the year in Ontario coincides with a backlog of old alerts... Thankfully, the old alerts cleared just in time for the tornado warnings and from what I can tell, those and our Instant Updates were sent super fast.... Besides that hiccup, how did the app perform for you yesterday? - Adam P.S. We really need an auto-expire on our Updates. I just noticed several this morning and cleared them. Thankfully, they have the time and/or date!

11:36 PM - Wed, Sept 30, 2020: Couple of noisy thunderstorms out there but not seeing anything concerning besides lightning. What are you experiencing? :)... - Adam

VALID: 5:44PM - Friday, October 23, 2020 Massive line of strong to severe thunderstorms stretching from North Bay to Windsor continues to track eastward. Strong wind gusts in excess of 90km/h are the main threat although the tornado threat remains. That storm just east of Orillia remains a big concern as it could be producing a tornado but those prefrontal storms are starting to weaken. ... Please let us know what you’re experiencing only if it’s safe to do so. - Brennen P.

7:32 PM - Wed, Sept 30, 2020: This is from earlier today. We hope everyone’s okay! https://twitter.com/jeremycohntv/status/1311443732978335746

Friday, Oct 23, 2020: I’m in the basement in #Barrie. Are you? Be safe, folks!! - Adam

Winter is coming and that means we have to start talking about the s*** word... We're focusing on the potential for some snow across Northern Ontario starting Thursday morning. But some scattered flurries may creep into the forecast for parts of Central and Eastern Ontario as early as this weekend! Although this may change as we get closer. Stay tuned as we’ll release a more detailed forecast on that in the coming days.... More details: https://instantweatherinc.com//cold-start-to-october-for-o - Brennen P.

VALID: 5:07PM: Friday, October 23, 2020 This is a VERY serious situation!! Storm with a clear hook heading right into Barrie. If you aren’t already, this is the time to seek shelter. A tornado is very likely being produced by this storm along with large hail. - Brennen P.
