Thursday: Stretch of nice weather begins in earnest

/ August 14, 2024 at 8:14 PM

High pressure wedging southward across the area has brought some cooler and drier air to the area this evening, with dewpoints falling into the mid-60s (it’s been a minute!). This will yield a fairly nice (but still warm) day on Thursday. We’ll start the day in the low 70s and warm to the upper 80s in the afternoon under partly cloudy to mostly sunny skies. With the lack of moisture and influence of high pressure, rain isn’t expected (and won’t be for a few days). Overall, not too shabby for mid-August!

Rest of the work week: A little bit of drier air as rivers slowly fall

/ August 13, 2024 at 8:08 PM

We have a bit of a respite from the rain and the extreme humidity on the way as a front slides south of the area and stalls tonight. Some lingering moisture and a trough of low pressure will allow for a few storms to remain in the forecast on Wednesday, though, as dewpoints slowly drop through the low 70s throughout the day. We start the day in the mid-70s and warm to the upper 80s in the afternoon, capped by some of that cooler and drier air trying to move back in. Expect the best chance of showers and storms from roughly 2-10PM. A few downpours can’t be totally ruled out as the deeper moisture only really starts to scour out Wednesday night, so a flood advisory or two could still be possible.
