Cooler in the Northeast Thursday through the weekend

1. After seven consecutive days with high temperatures of 90 degrees Fahrenheit or higher (all of them setting new records for their respective dates!), cooler air is reaching the area today. Meanwhile, most of the Northeast will be quite warm today, with temperatures in Boston higher than 80 this afternoon. However, the cold front now crossing the Great Lakes will reach the Northeast coast tomorrow. The cooler air will be reinforced Friday night and Saturday as a minor disturbance aloft moves from the Great Lakes to the coast and causes stray showers. These maps show the setup as of early this morning:

Note Tropical Storm Maria east of the North Carolina coast. The cold front from the west will help sweep it out to sea Friday and Saturday.

2. In yesterday's report, I showed upper-air forecasts that pointed toward a warmup for at least the early and middle parts of next week. That prospect has not changed.
