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

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.

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.

More Wintery Weather on the Way for Southern Ontario Starting Tuesday Evening; 612cm of Snowfall Accumulation Possible in Some Areas by Wednesday Details with accumulation and timing: https://instantweatherinc.com//more-wintery-weather-on-the - 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.

We’d like to take a moment to thank all of the wonderful hydro crews working out in the wind and rain to get everyone back on the grid. We appreciate you!! - IWO

How’d our app perform for you today? We hope everyone affected by these damaging winds stayed safe! - Adam

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.
