Today – a taste of spring, but you'll want to enjoy it while you can as the rest of the week will feature a storm and eventually a return to winter!
Despite a northwesterly flow, temperatures aloft will be fairly mild today. 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 a partly sunny sky! Savor the pleasant weather while you can, because conditions are going to head downhill starting tomorrow - that's when a fairly potent storm will take aim on Southern New England. The storm center will pass very close to the Connecticut shoreline Wednesday night, which means we'll be dealing with precipitation mainly in the form of rain. Meanwhile, heavy snow will fall across Northern New England and much of Upstate New York. A Winter Storm Watch has already been posted for parts of 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 (perhaps a little mixed precipitation at the onset). 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 begins pulling away from CT 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 work-week. Temperatures will start out in the teens Friday then rebound to between 35-40 degrees.
The weekend is looking fairly uneventful. There could be a couple of snow or rain showers Saturday, but no significant precipitation is expected. Plus, temperatures will get back to normal with highs in the 40s both days. The mercury could even nudge the 50 degree mark in some parts of the state Saturday afternoon.
Monday of next week, also known as St. Patrick's Day… it appears that winter weather will persist, at least temperature-wise, with highs in the 30s!!!
Have a terrific week!
