It would be hard to conjure up a better forecast for the long Labor Day weekend coming up. We'll have one more blast of near-90-degree heat on Thursday. But there's a slow-moving cold front headed our way from the north and west, and after a small threat of rain late Thursday and Friday,  as the front slides through, we're golden for the weekend.

Look for a high of barely 80 degrees on Saturday, with drier air and lots of sunshine as high pressure builds into the region behind the front. Sunday and Monday will be even sunnier, but only a bit warmer, with highs rising only to the mid-80s. 

This week could be our final flirtation with the 90s this summer. Average daily high temperatures in September slip from the low 80s into the 70s. Ninety-degree weather isn't unheard of. But those occasions approach record territory in September. By month's end, the record highs are in the low 90s.

Headed for the beach this weekend? Here's the forecast. Don't forget the sunblock. You still need it.
