Man is it gonna be warm and disgusting tonight.. I love it!
If you're right next to the water in the Chesapeake bay, you might not get below the upper 70s tonight because the water temps are around 75 and warming quick.
I'd imagine with the potential sustained heat pattern developing around June 20th, as the ULL decays over the southerly regions, the water temps rise near the mid 80s by mid July. Insane warmth last year in those waters. Some isolated spots didn't get below the mid 80s at one time during the July heatwave because the damn waters were incredibly warm!
