Today we experienced the coldest day of the year so far, with some inland locales approaching 0 degrees for the low, with quite unseasonably cold single digits at the shoreline. Thankfully, the winds failed, by-and-large, to produce, so windchills were cold but not quite as dangerous as first thought. Throughout the day, temps steadily rose through the 20s throughout the state, with some of the northern towns at higher elevations struggling to make it out of the mid to upper teens. Conditions thankfully stayed sunny to mostly sunny through the day. Looking to tonight, we start off with fair conditions early, with temperatures staying pretty much where they are right now, if not dropping off a degree or two. Later this evening, clouds start to increase in advance of our next weather maker, and probably the reason you are reading this forecast right now.
A 2 part system, which will be impacting our weather through pretty much the entire weekend, is currently centered in the mid-west and will gradually track north and east through the Great Lakes. With cold temperatures in our area, and warmth moving in ahead of aforementioned system, there will be warm air advection snows well in advance. Current timing for snows to move into the state, looks like around 2 am in far western and southwestern Connecticut, and overspreading the rest of the state by around 4 am. Snow could be heavy at times through the early afternoon, so please be careful if you need to travel during this time. Snow will gradually change to a mix then all rain starting in far southeastern Connecticut by mid-morning with the rain/snow line working its way north and west through the rest of the morning and early afternoon. Another aspect of this storm that we are worried about is the chance of some freezing rain, north of 95, and especially north of I84. Mid-level temps may warm far faster than ground levels leaving a risk of an extended period of freezing rain, especially during the afternoon and evening hours in the previously mentioned areas. That's shown here on the RGEM, valid for noon tomorrow.
Considering the slightly colder trend we have seen today, we have raised our forecast snow accumulations slightly across most of the state. Here is our new snowmap.
