MD 0089 CONCERNING FREEZING RAIN FOR NORTHERN VERMONT…NORTHERN NEW HAMPSHIRE…PORTIONS OF WESTERN AND CENTRAL MAINE

Mesoscale Discussion 0089
NWS Storm Prediction Center Norman OK
0700 PM CST Wed Jan 24 2024

Areas affected…Northern Vermont…Northern New
Hampshire…portions of Western and Central Maine

Concerning…Freezing rain

Valid 250100Z – 250500Z

SUMMARY…Freezing rain accumulations around 0.01-0.03 per per hour
likely through the evening.

DISCUSSION…Freezing rain accumulations of 0.01-0.03″ have been
reported across upstate New York over the last hour, with freezing
rain being reported at several stations across portions of Vermont
and New Hampshire. This threat will likely shift eastward into
western Maine over the next few hours. The observed 00z sounding
from GYX shows the profile is largely below zero from the surface to
just above 850 mb. Strong warm air advection is ongoing in low to
mid-level west to southwesterly flow from 850-500 mb. This is
further supported in RAP forecast soundings indicating warming above
the surface should support the downstream threat of freezing rain as
the heavier precipitation arrives northeastward. Areas across the
higher terrain of the White Mountains will likely see snow, with the
best potential for freezing rain accumulations located across the
lower valleys.
