This week’s comfortable and breezy air mass will be replaced with one a little more summer-like this weekend. The on-shore flow from the Atlantic is forecast to weaken, which will allow some higher humidity to build in from central and southern Florida starting Saturday. The lighter winds and increase in humidity might also allow for a few thunderstorms to develop along sea breezes on both coasts in the afternoons. However, coverage of the cells will be spotty at best, meaning most locations will likely stay dry this weekend. The lower coverage of thunderstorm activity, combined with the increase in humidity will make it feel a bit more like August than September, and daytime highs will be nearing the 90-degree mark on both Saturday and Sunday afternoon.
Our next cold front of the early fall season will arrive early next week. Upper-level winds are forecast to parallel the front, causing it to slow down as it passes. This might prolong the higher chances for rain through the middle of the week. Southwest winds ahead of the front will pump in plenty of Gulf moisture, and this teamed up with the cold front will result in likely rain chances Monday and Tuesday.
