Look for another hot one on Thursday. Afternoon temperatures will top out in the low to mid 80s. Fog will be possible again tonight as temperatures cool into the upper 60s across the area. Some of that fog could be dense early Thursday before burning off.
Right now a cold front looks to move through on Friday. That front will be mostly dry with just a few showers as it moves in. It will briefly drop the humidity to start the weekend with temperatures in the mid to upper 70s on Saturday.
On Sunday we see the warm air surge back ahead of a strong cold front coming in overnight Sunday night. Expect mid 80s across the area. That front moves through by Monday morning and that finally brings more of a substantial pattern change to the area. Most of next week will see highs in the 60s.
