The Nation's Weather 12.06.09

By WEATHER UNDERGROUND (AP)

High pressure was forecast to build over the East Coast on Sunday as the strong storm that brought rain and snow to the region on Saturday moved into the northern Atlantic.

Temperatures were expected to start out chilly in most locations, but were to warm up slightly throughout the day. Temperatures east of the Appalachians were forecast to reach into the 40s while the eastern interior could expect temperatures to hover right around the freezing mark for much of the day. The high was also to bring clear skies to much of the region, which could help melt any snow that accumulated Saturday.

Chilly temperatures were to spread south along the Eastern seaboard with below freezing temperatures expected as far south as northern Florida.

High pressure also was to remain in place across the Plains, where despite sunny clear skies, temperatures were expected to cool off a bit, with temperatures forecast to fall far below normal.

West of the Rockies, high pressure was to keep the skies clear. Temperatures were expected to remain chilly along the West Coast, with the Northwest seeing highs well below normal, and more southern locations only moderately cooler than normal.

Temperatures in the lower 48 states Saturday ranged from a low of -9 degrees at Crane Lake, Minn. to a high of 83 degrees at Fort Lauderdale, Fla.
