Good Monday evening!
Temperatures range from the mid 30s to near 40 at this hour. Sky conditions vary from partly to mostly cloudy across the state. There are no rain or snow showers at this time. Winds are generally light at under 8 mph in most locations. The forecast remains on track.
This week is going to feature plenty of volatility when it comes to the weather. In other words, we are going to experience typical March weather where one day it feels like spring then the very next day we get a nasty reminder that winter isn't over yet.
Tomorrow will be the nicest day of the week with a hint of spring in the air. Despite a northwesterly flow, temperatures aloft will be fairly mild. Plus, we are now dealing with much stronger sunshine than we had just a few short months ago. The result will be a fairly mild day with highs in the 50s under partly sunny skies! Enjoy the nice weather while you can, because weather conditions are going to head downhill by Wednesday. That's when a fairly intense storm will take aim at Southern New England. If fact, the storm center will pass very close to the Connecticut shoreline Wednesday night. The associated warm front could actually advance northward into portions of the state. Since mild air will surge northward toward Southern New England, this storm will come mainly in the form of rain. Heavy snow will fall across Northern New England and much of Upstate New York. A Winter Storm Watch has already been posted for Western Massachusetts, but a Winter Storm Warning is in effect for portions of Vermont and much of Upstate New York. No weather alerts have been issued for Connecticut, at least for now.
Here is the timeline: Light rain will develop in Connecticut Wednesday morning with some mixed precipitation possible at the start. Rain will become steadier during the afternoon and evening. With the warm front in the vicinity, the rain could become convective in nature. That means we can expect a few heavier downpours and perhaps even a few rumbles of thunder. The storm will move away to the east of Connecticut by late Wednesday night and the atmosphere will quickly turn colder. Rain will change to snow or snow showers in the pre-dawn hours of Thursday and snowflakes will linger in many parts of the state through the morning commute. A coating to 3" of snow could accumulate Thursday morning with the higher end of that range likely occurring in the higher elevations of Northern and Western Connecticut. The sky will begin to clear Thursday afternoon, but we'll have to deal with a cold northwesterly wind throughout the day that could gust as high as 40 mph! High temperatures will only be in the 20s to near 30 with wind chill readings in the single digits and teens.
High pressure will bring much calmer conditions for the end of the workweek. Temperatures will start out in the teens Friday morning and highs Friday afternoon will range from 35-40 degrees.
The weekend is looking fairly uneventful. There could be a couple of snow or rain showers, but no significant precipitation is expected. Plus, temperatures will get back to normal with highs in the 40s both Saturday and Sunday. The mercury could even nudge the 50 degree mark in some parts of the state Saturday afternoon.
Have a terrific week!
