Record highs possible Friday

The United States’ East Coast has experienced a period of unusual warmth this week. High temperatures in Boston have been in the 50s and 60s (°F) nearly every day for the past week, and we haven’t seen a high temperature below 50°F (10°C) since all the way back on Oct. 25. Normally, temperatures like this are more often observed in the first few days of autumn than in the first few days of November.

The anomalously warm weather will continue for the next two days in advance of a deep low pressure system that is forecast to pass to our northeast. Between now and tomorrow night, New England will be situated in the warm sector of this cyclone, with warm air being swept across the region by southwesterly winds. In Boston, the record high temperature for Nov. 6 is 73°F — a mark that may be equaled or even surpassed tomorrow.

A strong cold front will pass through the area on Friday night, bringing with it the chance of showers, and knocking temperatures down by roughly 20°F (10 K) by Sunday. While temperatures will be more seasonable, an incoming high pressure system should provide lots of sunshine for the beginning of next week.
