Snow is overspreading the state now (It’s 7:15 PM as I write this). Most of the snow is light and spotty with a lot of dry air to overcome. But once the dry air erodes, snow will become steadier and heavier.
A coastal storm developing overnight will promote an easterly wind. This will cause snow to transition into a wintry mix in the predawn hours of Tuesday. By the morning commute (7-8 AM), most of the accumulating snow is already over with a mixture of sleet, freezing rain, and rain (shore). Areas in the northern hills might take a little longer to change over. This nasty mix will continue off and on throughout the day. Then as cold air moves in back behind the storm, a change back over to snow is possible late Tuesday into Tuesday night.
If we get a good burst of snow late Tuesday, some additional snow accumulation is possible. A coating to an inch for most. But the northwest and northeast hills, along with areas bordering Massachusetts could see several inches of additional accumulation.
So how much snow are we talking about here? By tomorrow morning I expect 2”-3” of accumulation on the shoreline with 3”-5” inland and close 6” in the northwest and northeast hills. Additional accumulation may occur during the day in the hills on the order of 2”-4”. But the majority of the state will be done with accumulating snow after tomorrow morning.
