Take it in! One last day of un-muggy weather spoils us. It actually may be the best day for some time, based on how the forecast turns muggy. Then, even behind a cold front, the weather stays very warm into next week.
With dew points at or below 60 degrees promoting fairly comfortable humidity levels, we should be able to enjoy warm upper 70s to low 80s without much humidity-induced sweating. A light 5 to 10 mph easterly breeze brings slowly increasing moisture into the air, and some clouds with it — at times— too. It could be close on the cloud-cover percentage for Nice Day Stamp purists, but it’s a very pleasant day either way. Confidence:
Tonight: Skies should be partly cloudy and perhaps turning cloudier into morning. The Harvest Moon rises in a bright, noticeable manner — it should be visible even if there is a slight shroud of clouds. Evening temperatures in the 70s until nearly midnight should bottom out by dawn around 60 outside of the Beltway. Upper 60s are more likely downtown. East-southeasterly breezes around 5 mph are probable for much of the night. Confidence: Medium-high
Tomorrow (Saturday): Warmer and muggier air reruns. It’s not oppressive, but I think you’ll notice some stickiness, as dew points hover in the mid-to-upper 60s. Outdoor activities are probably still a go but watch radar late day, just in case, since there is about a 15 percent chance of a shower. High temperatures, despite variable clouds, reach the near-80s to mid-80s range. East-southeasterly breezes around 5 to 10 mph may blow a little gustier at times. Confidence: Medium-high
Tomorrow night: It’s mostly cloudy and we have a 20 to 30 percent thundershower chance, mainly in the evening. This is hit-and-miss stuff if any forms, probably mostly miss. Our region is dry and could use rain. And so could allergy sufferers. Pre-dawn low temperatures stay in the low 70s downtown with mid-to-upper 60s elsewhere. South-southeasterly breezes between 5 to 10 mph look likely. Confidence: Medium
Sunday: Clouds may again dominate, with increased shower and storm chances late. Conditions are even warmer and muggier than Saturday, as a cold front approaches and we experience the moist southerly flow of wind ahead of it. Dew points around the steamy 70-degree mark are possible, with high temperatures easily getting into the mid-and-upper 80s. 90 degrees can’t be ruled out in some spots, especially south of town. The odds of storms grow during the afternoon, and become likely heading into evening. Confidence: Medium
Sunday night: Let’s hope this cold front is indeed a bit slow to push across the region. It helps showers and storms (60 percent chance, as it stands now) move at a slow enough pace to give at least some of us a decent dose of rain. Low temperatures in the upper 60s to low 70s are likely. Even a few spots of mid-70s possible, if the front slows down even further and continues to pump in warm and juicy air from the south. Confidence: Medium
Clearing skies and drier air builds back into the region Monday and into Tuesday. Both days may still get 10-plus degrees above average — into the mid-to-upper 80s; but, at least dew points appear to want to stay out of the steam-bath arena. After a few possible lingering showers Monday morning, we see limited (maybe 20 percent) chances for rain Monday afternoon through Tuesday. Sorry that autumnal weather appears to be pushed out even further, now . . . Confidence: Low-medium
