Slop Update
Wednesday, March 9, 2022 - 7:00 A.M.
I am not making any changes to the forecast since yesterday, other than to slow the start time of the precipitation a bit. It looks like wet snow and rain will spread from south to north across Connecticut and Rhode Island between approximately 9:00 A.M.-11:00 A.M. this morning and reach all areas of northern Massachusetts by early afternoon. In places where the precipitation begins as rain, it will tend to go over to mostly wet snow as the temperature drops a little after the precipitation saturates the air near the ground. It looks like some areas of moderate to heavy snow will fall across parts of region this afternoon, however with marginal temperatures (above freezing at the surface) in many places, combined with the higher March sun angle, the snow will have more difficulty accumulating that it would in December or January.
It looks any lingering snow or flurries tonight will end between 7:00 P.M.-10:00 P.M. in most places, followed by partial clearing. Any wet or slushy surfaces tonight will become icy as low temperatures fall into the 20’s. I am still anticipating 1”-4” of snow accumulation across most of the region. Higher elevations, being a little colder, will tend to have the higher amounts, with snow sticking to more surfaces and roads than lower elevations, where there will be more melting and snow sticking better to grassy surfaces.
I like the way the High Resolution Rapid Refresh model is handling the precipitation thus far, so will continue to use it as a guide for now.
