Well below average temperatures will lead to the season's first flakes for many Thursday morning.
A hard freeze is expected tonight, and it will end the growing season in much of southern Connecticut, especially away from the immediate shoreline.
Wednesday will be mostly sunny, and temperatures will rise into the upper 40s in the afternoon.
Thursday brings the forecast challenge of precipitation.
Early Thursday morning, temperatures will be below freezing across much of Connecticut. The hill towns may dip as low as the middle 20s.
High pressure will be in a good position to keep the cold in place initially at the surface, and as a result, snow is possible across inland Connecticut late Thursday morning.
The snow and rain will likely begin between 11 a.m. and 2 p.m. Thursday.
Temperatures will eventually rise above freezing, leading to a mostly rain event for the whole state by afternoon.
While snow accumulation is unlikely and most will just experience wet roads, the northwest hill towns could see a slushy accumulation.
Shoreline areas will just experience rain on Thursday. It will be cold, with highs only near 40 inland but up near 50 at the shoreline.
Behind the storm on Friday, an abundance of clouds will stick around.
This weekend, it will be mostly cloudy. The best chance for showers will come on Sunday, when temperatures surge into the middle 60s.
Halloween looks dry and seasonable as high pressure builds in. High temperatures during the afternoon will be in the upper 50s, but 40s are expected after nightfall.
