=== NWS Regional Summary - 421 AM EST THU FEB 13 2003 ===
Bitter mid winter cold will affect the region through Friday. Arctic air from
the plains of central Canada continued to invade the region on a gusty
northwest wind overnight. By daybreak, as winds diminished away from the
shore, temperatures had dropped to 5 below zero in southern New Hampshire and
the low lying areas of the lower Connecticut valley, to 15° on the islands. In
spite of bright February sunshine, temperatures will struggle to reach the
teens across the interior, and the lower 20s by the shore. Clear skies and a
deep snow cover will allow for one of the coldest nights of the year tonight,
with temperatures falling into the single numbers along the shore to as cold
as 20 below zero in protected valley locations of northern Massachusetts and
southern New Hampshire. Friday will be fair and continued cold with high
temperatures only a few degrees milder than today. Looking ahead to the
weekend, it appears that old man winter's grip will not last as long as
January's frigid handshake. Temperatures will climb back to more seasonable
normals, but with that slow climb will come the chance of more snow.
