10:15 a.m. – Clouds hanging around this morning

Some showers were still in the area early this morning and the clouds have been slow to dissipate. As such, it’s cloudier than anticipated for the morning, which may help keep temperatures down a notch or so. We should still see some clearing before more rain tries to develop later today. One caveat with that is the longer the clouds hang around, the less instability we end up with. Stay tuned …

From 5:00 a.m …

A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

5/10: Not the best, but it’s (hopefully) not 90 either!


Today: Partly to mostly cloudy. Showers and storms. Highs: Mid- to upper-80s.
Tonight: Showers waning. Mostly cloudy. Lows: Low- to mid-70s.
Tomorrow: Partly cloudy. Fewer late-day storms. Highs: Near 90.

This respite in heat isn’t ending up much of a respite. Indeed we may see highs stay below 90 today, but that could be it in this stretch. With lower temperatures comes more in the way of clouds and rain. And conversely, as temperatures rise in the days ahead, rain chances go down. It’s certainly not going to feel like September any time soon.

Today (Saturday): A day a lot like yesterday, except the front is a bit farther south to start. This might mean less in the way of heating. Highs should generally rise to the mid-80s, but perhaps some temperatures in the upper 80s will occur as well. Skies are increasingly cloudy through the midday, with showers and storms increasingly likely over time into the afternoon. Any rain can be heavy with some localized flash flooding a risk. Confidence: Medium-High

Tonight: Showers and storms should wind down during the evening and into the overnight, with just a passing shower risk late. It’s soupy and some patchy fog may develop overnight, as lows reach the low- to mid-70s. Confidence: Medium-High

Tomorrow (Sunday): More of the same overall, except I think more sunshine is likely, so probably fewer afternoon showers and storms. The humidity may even tick up slightly, which is just unfair at this point. With highs in the upper 80s to near 90, heat indexes will approach 100. Confidence: Medium

Tomorrow night: With dew points into the mid-70s in many spots, it’s about as sticky as it gets this time of year. High dew points means high overnight lows. They’re only in the mid-and-upper 70s. Confidence: Medium

Hot and humid is the story both Monday (Labor Day) and into Tuesday. This looks a lot more like July than September, as high temperatures rise to a 90 to mid-90s range and dew points remain in the mid-70s or so. Any afternoon showers and storms are isolated to scattered, which should generally mean fewer than recent days. Confidence: Medium
