DISCLAIMER: ANALYSIS, NOT PREDICTION!!!
Last 5 GFS model runs all staying consistent, and extended weather forecasts are now starting to buy in on a "better late than never" arrival of Fall's first front a week from today, coming on the heels of some possible rain Wednesday. Unfortunately, gonna continue to feel like Neverending Summer until then.
Doesn't look like temps are expected to come down drastically, maybe ~10 degrees off current highs and ~5 degrees off current lows, but dewpoints look to plummet a good 30 degrees, meaning that it would feel exponentially more pleasant.
Also nice to see that, AS OF NOW, this appears to be more than a 2-3 day flash in the pan. Forecast after next weekend doesn't immediately revert back to hot and swampy.
7 days out is when you just barely get a toe over the line of usefulness, so I'd put maybe 55/45 odds on things panning out at this point. If models are still producing similar runs by the end of this weekend, I'm going all in. This late in the year, it has to happen eventually (or does it?)
