#ONStorm #ONwx 11:10PM - Sun, Jan 16, 2022:

The snow has started to make its way into our region late this evening. We are also seeing this very sharp gradient setting up on the northwestern edge of the system. This is why we had so much uncertainty with the expected accumulation in this area. You can see that London is currently under a very intense band of snow but just a few kilometers to the northwest and there’s barely a flake.

#ONStorm #ONwx After reviewing the latest high-resolution data this evening, we're becoming quite concerned about the GTA around Lake Ontario into Eastern Ontario.

Models are showing intense snowfall rates of 5-10cm PER HOUR (yes, that's in one hour). Combined with wind gusts approaching 50-80km/h will lead to potentially dangerous blizzard conditions along the Lake Ontario shoreline and parts of Eastern Ontario. The worst conditions will start around 3 am and continue until noon.

#ONStorm #ONwx UPDATE: Monday’s Snowstorm Shifts Further West Bringing the Threat of 20+cm of Snow Into the GTA and Central Ontario; Up to 50cm of Snow Possible for Niagara and Eastern Ontario

Read here: instantweather.ca/articles/2022/… Once again, we ask you to please *read* the entire forecast as many of your questions and concerns will be answered there. This is a very complex system and just reading the headline or looking at the map won't be that helpful.

#ONStorm #ONwx You may have seen a 'storm chip' forecast circulating on social media for the Maritimes.

We've had many requests from the community to bring the storm chip forecast to Ontario. So we've done just that... introducing our first 'Storm Chips & Hot Cocoa' forecast! Clearly, this isn't meant to be a scientific forecast by any means. Storm chips tend to be more of an Atlantic Canada tradition, however, it appears to be catching on here. We figured why not put out something a little more light-hearted to ease the stress of this snowstorm.

#ONStorm #ONwx Gooood morning everyone!

We’ve been continuously going over the latest data for the significant snowstorm affecting Southern Ontario late tonight into Monday. The models continue to trend with a slightly more western track which means higher snowfall totals are possible. Those in our ‘uncertain’ zone will likely see more snow than shown on our map from last night (included in the tweet).

#ONStorm #ONwx Potentially Strongest Snowstorm in Years To Bring Up to 20-40cm of Snow to Parts of Southern Ontario Starting Sunday Night; Localized Blizzard Conditions Possible Monday Morning

Full detailed forecast: instantweather.ca/articles/2022/… It's very important to *read* the entire forecast instead of just focusing on the map. There are a lot of variables with this system in particular which makes it very difficult to forecast.

A look at what it’s forecasting for the upcoming snowstorm on Monday…

The highest total we could find is Kingston with 48cm!! 😳 Our app uses a unique method different from our custom forecasts and can be useful to compare the two different forecasts for your location.

NOTE: The app will show snowfall totals before sunrise on Monday under Sunday’s forecast.

#ONStorm #ONwx Wow... the model data this evening is quite something if you were hoping for a good snowstorm across Southern Ontario on Monday.

All of the major models (NAM, GEM (Canadian) and GFS) have a notable westward trend in the track of the system. Still waiting on the European model but it had this same western trend in earlier runs so we expect it will agree.

What does this mean for us? Well, confidence is growing for a very impactful snowstorm across Eastern Ontario and around the Golden Horseshoe...

#ONStorm #ONwx EARLY PREVIEW: Snowstorm Could Bring 15-25+cm of Snow to Eastern Parts of Southern Ontario on Monday

Details: instantweather.ca/articles/2022/… We believe it’s important to post a forecast this early due to the potentially significant impacts it could have on our region. This is now your chance to plan for a snowstorm and make any alternative arrangements for Monday should it occur.
