The sun has returned to save the holiday weekend! Over an inch of rain from the remnants of Hurricane Harvey fell the past couple of days but that storm is now north of Maine and we are in for a couple of sunny and warm days. The city should warm to around 80 this afternoon and the mid 80s tomorrow.
Tomorrow's warmer weather will be accompanied by increasing humidity and a good chance of showers or thunderstorms by late afternoon. The best chance of storms will be north of the city, however.
The rain is a result of a slow-moving cold front and an unusually deep southward dip in the jet stream. That combination will set us up with return for the weekend as a broad area of high pressure finally pushes the cold front away.
That high pressure system is one of the keys to what happens with Hurricane Irma. That storm is currently expected to strengthen this week as it passes just north of Puerto Rico, the Dominican Republic and Haiti before striking Cuba on Saturday. The most recent model runs then have Irma turning north and heading straight up the Florida peninsula. Next Sunday is as the far the model's forecast abilities reach, so there is not yet a lot of confidence in that forecast.
