=== NWS Regional Summary - 544 AM EST THU FEB 22 2007 ===
Skies were clear overnight and morning lows were in the teens and 20s across
southern New England. Clouds will rapidly increase this morning and
precipitation will develop during mid afternoon, probably in the form of mixed
rain and snow. Highs today will range from the mid 30s to near 40 western
Massachusetts and southwest New Hampshire and between 40 and 45 elsewhere.
Mixed precipitation should end as all snow in much of the region late tonight.
A brief period of heavy snow is possible from the east slopes of the
Berkshires and high terrain of northern Connecticut into Rhode Island and
south coastal Massachusetts. Conditions could be quite nasty on the lower Cape
and Nantucket overnight with sustained winds around 30 mph gusting past 45 mph
and rain or snow falling heavily for a little while there too. Lows will range
from the lower 30s south coast to the upper teens Worcester hills and
Monadnock region. Friday will see clearing but it be windy. Temperatures will
remain below freezing, values actually steady or falling through the day! Any
leftover ice from the valentines day storm or the overnight snow will freeze
solid by nightfall. Saturday will continue windy and cold but essentially dry
and then there should be less wind on Sunday as high pressure builds into the
area from central Canada. On the weather map, low pressure near Lake Huron
this morning will redevelop south of Long Island this afternoon and then
become an intense storm as it moves out to sea to the southeast of Nantucket
early Friday. A secondary cold front will cross the region Friday morning and
usher in a windy couple of days.
