MD 0288 CONCERNING WINTER MIXED PRECIPITATION FOR PORTIONS OF SOUTHERN MAINE AND NEW HAMPSHIRE
Mesoscale Discussion 0288
NWS Storm Prediction Center Norman OK
0457 PM CDT Sat Mar 23 2024
Areas affected…portions of southern Maine and New Hampshire
Concerning…Winter mixed precipitation
Valid 232157Z – 240100Z
SUMMARY…Mixed precipitation should continue across portions of
northern New England over the next few hours. Freezing rain is also
possible, with ice accretion rates exceeding 0.05 inches/3 hrs in
some spots.
DISCUSSION…A surface low, located just off the coast of NJ, is
poised to traverse the coastline through the evening as a mid-level
trough overspreads the region. Strong surface-700 mb
warm-air/moisture advection is underway along the New England coast,
promoting widespread wintry precipitation. Snow should remain the
predominant precipitation type across northern parts of ME and NH.
However, temperatures are rising above the freezing mark in the
lowest couple hundred mb, allowing for mixed wintry precipitation to
occur. Along and just north of surface freezing line, ice
accumulations have been reported, and ice accretion rates of up to
0.05 inches/3 hrs, as well as sleet, are possible where rainfall is
heaviest.
