Tuesday...
Shortwave trough approaches from the west increasing the forcing
for ascent. The result will be snow overspreading the region
from west to east Tuesday morning and continuing for much of
the afternoon. There is some modest lift indicated in the
snowgrowth region and the warm advection developing over the
cold dome supports widespread accumulating snow for most of
southern New England. After coordination with surrounding
offices, opted to hold off on Winter Weather Headlines with this
package but they will likely be needed. Ptype should mainly be
snow, except perhaps near the south coast, Cape and Islands
where some boundary layer warmth may result in a change to rain.
Current indications are for a general 2 to 5 inches of snow
across the region on Tuesday. The one thing will need to watch
is a weak wave of low pressure passing to our south. There is a
southwest LLJ on the order of 35 to 45 knots. If this wave can
setup some sort of low level boundary, it is not out of the
question for localized higher snow amounts. Something will have
to keep an eye on over the next 24 hours. Regardless, another
accumulating snow event is on the way.
