=== NWS Regional Summary - 550 AM EST MON JAN 20 2003 ===
Bitter cold headed for southern New England. An area of snow showers was
moving across the region early this morning. Temperatures at 5 am ranged from
the single digits to 12° across southern New Hampshire to the 25 to 30° range
along the south coast, Cape Cod and the islands. The snow showers will come to
an end by early afternoon, but this will usher in bitterly cold and blustery
conditions later today through Wednesday night. The coldest temperatures of
the winter season will be recorded both Tuesday and Wednesday nights. These
frigid temperatures, combined with northwest winds at 15 to 25 mph to produce
wind chill readings between 15 and 25° below zero tonight. Even though skies
will be mostly clear, arctic air will continue to spill across New England on
Tuesday and Wednesday as high pressure builds to the west of the region. Air
temperatures will fall to below zero across most of the area, even in the
urban centers of Boston and Providence, on Tuesday night. Only the south
coast, Cape Cod and the islands will barely escape subzero readings. Northwest
winds will continue, so wind chill values will be even colder, in the 20 to 35
below zero range.
