Wilton is in store for a brutally cold week (December 12-18), with temperatures falling as the week progresses. There are also multiple chances for snow, but none of those chances feature significant snowfall, as of now.

Monday, Dec. 12:  The new week will kick off as an ugly one–and potentially a delayed one–because Wilton Schools may actually be delayed in the morning due to the weather. Snow early Monday morning will transition to rain, probably around 3 o’clock, due to Winter Storm Caly (name of storm given by The Weather Channel, which Jackson’s Weather utilizes). That rain will continue for the rest of the morning, ending by noon. Therefore, while the rain may melt all of the early morning snow, I’m concerned that the roads may still be slick and possibly icy because ground temperatures will still be below freezing, especially in northern Wilton. That’s why I am giving it a 35% chance for a school delay. In the afternoon, skies will gradually clear with temperatures in the mid 40s.

Tuesday, Dec. 13:  Tuesday will be the nicest day of the week, in my opinion, because there will be sun and clouds, pretty light winds, and temperatures around 40 degrees.

Wednesday, Dec. 14:  Expect very similar weather conditions on Wednesday with intervals of sun and clouds and slightly below average temperatures. Enjoy that 40-degree high because temperatures for the rest of the week will get very chilly.

Thursday, Dec. 15:  A piece of the infamous polar vortex will plow into the Northeast beginning Thursday, so temperatures will be falling throughout the day with a high of only 24 degrees! With that Siberian cold front pushing through, winds will be blowing strong up to 40 mph. Therefore, wind chills or feels like temperatures will only be in the single digits under sunny to partly cloudy skies.

Friday, Dec. 16: On Friday as you wait for the school bus outside, you’re going to want to bundle up! Have the winter coat, scarf, gloves, and hat because you’re going to need it with actual low temperatures likely to be in the single-digits. It may even drop to 0 degrees with “feels-like” temperatures between minus-5 and minus-15 degrees. I wonder if we get a school delay for extreme cold? At least it will be a mostly sunny day, but that won’t warm you up that much. In the afternoon, we’ll be lucky to even reach 20 degrees.

Saturday, Dec. 17:   The next shot for wintry weather arrives just-in-time for the busy pre-holiday weekend. As of now, I’m predicting for morning snow to changeover to rain due to above freezing temperatures. Because of that quick transition, minor snow accumulations is expected, but we’re still about a week away from this event, so stay tuned!

Sunday, Dec. 18:   Now on Sunday, some of the models are honing in on a second storm system, but there is so much uncertainty that I’m just going to forecast the chance for rain and/or snow showers before the next potential cold shot arrives next week.
