=== NWS Regional Summary - 438 AM EDT THU APR 5 2007 ===
Low pressure just south of Nantucket at 4 am, delivered periods of heavy rain
overnight with widespread 1" rainfall across much of Connecticut, Rhode Island
and southeast Massachusetts. Farther inland where the atmosphere was cold
enough to support snow, accumulations of 4 to 7" were common across southern
New Hampshire. Farther south across northern Massachusetts, most locations
picked up 2 to 3" of snowfall. As the low tracks northeast into the Gulf of
Maine today, some breaks of sunshine should develop this afternoon. Despite
some sunshine, brisk west winds will transport cold air into southern New
England, with temperatures only climbing into the low and mid 40s this
afternoon. Across northern Massachusetts and southern New Hampshire, the fresh
snow cover will limit highs to the upper 30s today. Other than a brief snow
shower tonight and Friday, brisk dry weather will prevail with temperatures
continuing to run below normal. Winds will slacken Saturday, however
temperatures will remain cool with highs only in the 40s. An ocean storm is
expected to develop well south and east of New England Saturday. However, a
period of light snow may graze southeast Massachusetts Saturday afternoon. As
the ocean storm intensifies Sunday, a reinforcing surge of cold air will
overspread southern New England.
