November Preview

A massive and cold high pressure system will slowly edge eastwards toward New England from the Mid West, cresting overhead by Saturday. With temperatures averaging about 1015 degrees Fahrenheit below normal, first frost of the season is expected inland by Friday morning, and widespread frost - even near the coast - by dawn on Saturday. Gradual warming of the airmass over the next few days is forecast, with temperatures returning to a more seasonable levels for early October. Thus, by Monday, under fair skies and some high clouds associated with warmer air aloft streaming in from the west, we'll be back to normal highs in mid 60s (1618C) and more tolerable lows in the upper 40s (89C).

Hints of stormy weather for the middle of next week hinge on a developing low pressure system in the Gulf by late in the weekend, a stationary through over the western Atlantic, and an upper air impulse swinging in from the west, converging on the Carolina Capes by late Tuesday. Meanwhile, a crisp, brilliant fall weekend with early foliage viewing well to the north is assured.

Today: Mostly sunny and cool. Bracing northwesterly breezes. High 54F (12C).

Tonight: Clear and very cold with diminishing winds. Widespread frost due to ideal conditions for radiational cooling. Low in town 33F (1C), mid to upper 20s (-4 to -1 C) elsewhere.

Saturday: Cold morning, then warming up to a mostly sunny daytime high of 56F (13C). Light northerly winds may turn into afternoon sea breezes.

Sunday outlook: Mostly sunny amid patches of high thin clouds. Milder highs near 60F (1416C), with lows near 40F (45C).
