Canadian Chiller

By Marek Zebrowski
Staff Meteorologist

A cold high pressure system will slowly move over our area this weekend, bringing lots of sparkling sunshine and bone-dry northwesterly winds for Friday. As this systems crests overhead Friday night, expect calm and near-frost conditions in the colder valleys of central and northern New England. Light sea breezes and high, thin clouds will appear later on Saturday as the high moves over the Gulf of Maine towards the Maritimes, thus allowing some moisture to our south and west to approach us by later Sunday, bringing with it a threat of showers.

Meanwhile the tropics remain very active, with yet another Atlantic hurricane, Marilyn, located near the island of Dominica yesterday afternoon. Hurricane watches and warnings are up again for Puerto Rico and the Virgin Islands. With top winds exceeding 80 mph (130 kph) in gusts, Marilyn is less intense and much smaller hurricane then Luis, which caused a lot of destruction in the Carribean just last week. However, with some indications of weaker steering currents over the southwestern Atlantic and Marilyn's continuing northwesterly track, the Bahamas may be threatened by early next week and there is a chance of Marilyn affecting the U.S. mainland as well.

Today: Sunny, windy and cool. High 66F (19C) with gusty northwesterly winds.

Tonight: Clear with slowly diminishing winds. Low 47F (8C) in town, but in high 30s to low 40s (3-5C) to our west and north

Saturday: Mostly sunny with light onshore winds. High 64F (18C).

Sunday: Some sun early with increasing cloudiness throughout the day. Warmer, with highs in the low 70s (21-23C).
