Winter Chill this Weekend Followed by Wintry Weather

The days of the above average temperatures and quiet weather are gone here in CT, at least for the time being. The first of two arctic blasts are headed towards CT tonight. (Second one comes late next week) Temperatures are expected to drop into the 20s by early Friday morning. Highs this weekend will struggle to make it out of the 30s. Factor in a gusty and chilly NW breeze, it will certainly feel like the single digits and teens at times over the next 72 hours. Below is a forecast wind chill temperature early Saturday morning. When you wake up to take your dog for a walk, it will feel like the single digits to teens, Brrr! But that’s not all we’re expecting.  The first statewide accumulating snow is becoming more likely.

With the latest computer guidance from earlier today (12Z GFS, EURO and CMC) the likelihood for snow Sunday night into Monday is increasing. This is still a few days away, so things will likely change. Your best option now is to download the WTNH Stormteam8 App on your smartphone to stay ahead with all of our latest updates. You can download the app by clicking here. But what should you do now to prepare? The cold is coming for sure. Now’s the time to make sure you shut the water valve off to the outside faucets and bring the garden hose inside! Keep reading below for my first thoughts on the potential for snow Sunday night.

WHAT WE KNOW NOW: 

Conditions will be in place for accumulating snow Sunday night into Monday. With temperatures struggling to make it out of the mid 30s through the weekend, any snow that may fall will have no issue sticking quickly. It’s far to early to discuss snow totals, but with the current setup, we can expect snow statewide Sunday evening into the night with a changeover to a mix then eventually rain along the shoreline by Monday morning. (See graphic below) The exact track and timing will determine exactly how far north the rain/snow line will travel. Many towns in northern CT, especially the highest elevations may see an “all snow event” This is something we will be watching very closely over the next 24-36 hours and we should have a better handle on with the new data Friday morning. Any shift in track or timing will make a significant change in the forecast. However, not a bad time to dust off the snow removal equipment in your garage!
