Technical Discussion:
High pressure remains in control for most of the area, but low pressure moving into the Great Lakes will increase cloud coverage by late-day. Precipitation holds off until early Saturday, with just a few flurries possible well after midnight.
Precipitation overspreads the state on Saturday and it's still a challenging forecast. Wet snow could fall for a good portion of the daylight hours, but temperatures should rise into the mid and upper 30's. Expect a gradual change to rain near the coast. A slushy accumulation is possible in the hills, otherwise not expecting much snowfall.
Saturday night is when precipitation picks up and the northern hills should begin to see more in the way of accumulating snows. The computer models are in decent agreement with bringing the rain/snow line up to just about the CT/MA border. However, the highest elevations of Litchfield, Tolland and Windham counties might hover near the freezing mark. The result will likely be a back and forth switch from snow to rain and even some freezing rain and sleet in pockets. The column up to 800mb is nearly isothermal, so it only takes a slight change in temperatures or a burst of heavier precip to switch those areas over to a heavy, wet snow. Precipitation tapers off as wet snow in most areas Sunday morning before ending.  
For accumulations, the general idea is less than an inch near the coast, 1 to 3 inches for the interior and CT River valley, but 3-6"+ for the northern hills. Will have more maps and forecasts later on to break down the specifics.
Monday should break into mostly sunny skies and seasonable temperatures.
The next storm system looks like another wintry mix later Tuesday into Tuesday night. Will monitor later computer model runs for specifics on precipitation type and timing.

Today: Sunshine gives way to clouds. Highs in the mid to upper 30's.
Tonight: Clouds. A flurry possible in western CT. Lows in the mid-20's to lower 30's.
Saturday: Wet snow, changing to rain at the shore. Highs in the mid to upper 30's.
Saturday PM: Rain at shore, wintry mix to rain inland. Temps in the low to mid-30's.
Sunday: A wintry mix or snow ending by midday, breezy. Highs in the mid-30's to near 40.
Monday: Mostly sunny skies, seasonable. Highs in the lower 40's.
Tuesday: Increasing clouds. A wintry mix or rain at night. Highs around 40.
Wednesday: Mostly cloudy skies. Highs in the low to mid-40's.

Note: Inland temperatures are an average. Often times, outlying areas may be a few degrees cooler than the advertised temperature on the 6-day graphic.
