Snow showers are popping up across the region. They will gradually become more steady over the next few hours, and through 8 PM a coating to maybe half an inch of snow can be expected. A few isolated areas could approach an inch, but generally just about half an inch is expected. By 9 or 10 PM any snow showers wind down from this first round of snow.
There is a pause in precipitation between 9/10 PM and 1/2 AM. Then between 1 and 2 AM light precipitation overspreads the region, gradually getting steady by 3 AM. Though precipitation may initially be a burst of snow at the coast, it quickly turns over to rain by 2 or 3 AM. Inland we begin to turn to rain and freezing rain by 3 or 4 AM, and snow is enirely out of the region by 5 AM. We may see a couple hours of icing between 3 and 6 AM inland, but by 6 AM most of the region should see temperatures above freezing with only patchy icing very far inland. Rain showers will continue through the morning but should wind down by noon.
Accumulations overall will be quite limited. A coating to an inch of snow is expected at the coast, with most of that falling through 9 PM. Inland I expect a coating to 2 inches, with amounts less than an inch likely just north of the Merritt but accumulations approaching 2 inches possible near areas like Danbury before a turn to freezing rain and rain. Up to a tenth of an inch of ice could be possible in patchy areas inland as well, potentially necessitating Winter Weather Advisories. Far inland, 1-3 inches of snow is likely before a turn to rain, with up to a tenth of an inch of ice also possible. It is highly unlikely anywhere sees more than 2-3 inches of snow, even very far inland, and it is possible amounts are capped below 2 inches across the entire region.
