Good morning all. I wanted to update everyone regarding the forecast for tomorrow & Friday as we enter the unsettled portion of the week.

Wednesday

Temperatures hold steady and eventually begin to decrease during the afternoon as colder air from the north slowly drains south.

Thursday

While temperatures are the surface may be cold enough to support snow across the region, temperatures aloft tell a different story. Looking a few thousand feet above the surface, at 1 am Thursday morning, temperatures off the ground along the south coast are already above freezing. Through the morning and into the afternoon temperatures aloft (and eventually at the surface) will warm above freezing and flip snow quickly to sleet, freezing rain, and rain.

Based on the temperature profile of the atmosphere, the window for snow is really small in southern & central New England. Accumulations should be limited to an inch or two.

There won’t be much snow, but the Thursday AM commute will be slippery with the little snow, sleet & ice the region receives falling perfectly timed. When Thursday ends, southern New England will likely have forgotten that it snowed. Northern New England may have a few inches to show for it.

Friday

Friday’s forecast is very similar to Thursday minus the snow, sleet and freezing rain in southern New England. This time, temperatures are too warm and its plain rain. Northern New England should receive a decent snowfall from this round as temperatures cool during the storm and areas flip to snow.

Northern Maine could see upwards of a foot from round two as they are far enough north to stay snow the whole time.

Total Snow

In the end, this is a northern New England storm with only the Thursday AM commute being disrupted in southern New England.
