Arctic Cold Tonight/Tomorrow

The coldest air of the week will greet you Friday morning with wind chill values between -20 and -5 degrees. The afternoon doesn’t offer much reprieve. Temperatures will struggle to hit the 20 degree mark. Saturday is dry and not quite as cold. A few snow showers are possible Sunday but most of the day will stay dry.

The same storm that will bring heavy rain to drought stricken California on Friday will trek across the country this weekend. Plowable snow is becoming increasingly likely on Monday. There is still a lot of disagreement within the computer models.  This is to be expected since the storm is still over the Pacific Ocean tonight. (For more on a bit how computer models work, check out my last blog post.) 

Here’s what I can tell you.  This does NOT look like the set up to produce a blockbuster storm for us in New England.  No bombogenesis. No counting snow totals by the foot.  The worst case scenario for anyone in this storm from the Midwest to the east coast is a narrow band of 6”-12”.  Everyone else gets less! So does Connecticut fall within the jackpot amount? Or does the heaviest stuff just miss southern New England?  Those details will be ironed out in the next couple of days.  For now, plan on snow developing overnight Sunday and lasting through Monday.  Two commutes could be affected by this storm. But how much of an impact is still to be determined. 

Tonight: Early snow shower/flurry in spots. Low: 0-9. Wind chills between -20 to -5.

Tomorrow: Cold despite plenty of sunshine. Breezy start with wind diminishing. High temperatures in the upper 10s and lower 20s, about 20 degrees below average for this time of year.

Saturday: Increasing clouds, becoming mostly cloudy. High temperatures in the lower 30s inland, middle 30s for the shoreline.

Sunday: Mostly cloudy with a few snow showers. But most of the day looks dry. High temperatures around the 30 degree mark. Steady snow developing overnight.

Monday: Snow through the evening commute. Still a lot of uncertainty regarding the storm's track and accumulations. High temperatures in the lower to middle 20s.

Tuesday: Any lingering snow showers ending early in the morning. Otherwise, clouds breaking for sunshine. Breezy and cold. High temperatures in the middle 20s.
