D.C. area forecast: More low-humidity warmth today before muggy air starts to return this weekend

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

9/10: Another day of fairly low humidity and near normal temperatures. Put on sunscreen and enjoy!


Today: More sun than clouds. Slight breeze. Highs: Mid-80s to near 90.
Tonight: Fairly clear. Light breeze. Lows: Low 60s to low 70s.
Tomorrow: More sun than clouds. Highs: Upper 80s to low 90s.
Sunday: Mix of sun and clouds. Shower/storm? Highs: Upper 80s to low 90s.


Time is running out for our tolerable, less-humid warmth. Mugginess may start to creep back into the region as early as tonight—albeit slowly. Light breezes will help upper 80s to low 90s feel relatively “OK.” Saturday is a good pool or beach opportunity, and we may make it through the whole weekend dry. Heading into next week the mugginess really kicks back up, but it’s nothing to which we haven’t acclimated.

Today (Friday): Still bright, fairly blue, and perfect for sporting the sunglasses. Humidity still remains in check! Breezes are light out of the north (around 5 mph), but welcome since high temperatures get very warm into the mid-80s to near 90. A bit too warm for Nice Day criteria, but worthy of a high Daily Digit grade. Confidence: High

Tonight: A light northeast breeze during the evening hours should slowly calm down. Our air begins to feel a bit muggier–not terrible–overnight. And that slight and noticeable mugginess may be here to stay. Star gazers may have a chance to enjoy, since clouds should stay away for the most part. Evening upper 70s and lower 80s drop down before dawn. Temperatures should bottom out in a still somewhat comfortable range of lower 60s outside the Beltway to near 70 downtown. Confidence: High

Tomorrow (Saturday): Sorta tolerable. High temperatures in the upper 80s to low 90s are certainly very warm but we may—may—be able to eke out at least one more day without significant humidity. I suppose we can make time on a weekend day to head to the pool or beach, anyway, right? No storms appear to threaten! Head to the water. Enjoy the sunshine, with sunscreen of course. Confidence: Medium-High

Tomorrow night: Midsummer is when we seem to run out of cool air, even at night, with no sun! If out during the night, keep in mind we may be a bit steamy so it may not be totally comfortable. Skies should be partly cloudy, insulating us just a bit from cooling even a few more degrees if skies were clear. Overnight lows are in the low 70s downtown, perhaps mid-and-upper 60s in the outlying areas. Ah, well. It’s July. Confidence: Medium-High

Sunday: No big promises but it’s possible that a weak cold front nears the area. Don’t expect much, but perhaps a 20% chance of a shower or storm. Even if we stay more dry than not, clouds could dominate at times. It’s fairly muggy as well. High temperatures in the upper 80s to lower 90s are probable. Maybe we will all start hoping for a cooling shower by late afternoon! Confidence: Medium


Sunday night: Mainly cloudy with a few showers and perhaps storms rumbling around. Only but a 30% chance or so of getting damp. And, as it appears now, nothing too heavy. Low temperatures hopefully get into the mid-60s outside the Beltway, but hover perhaps in the mid-70s downtown. Confidence: Medium

Our workweek starts off with more of the same muggy, warm weather on Monday and Tuesday. Showers and thunderstorms (40-50% chance) that may threaten on Monday could leave us alone for a drier Tuesday. Check back for updates. High temperatures should at least hover around 90 if not end up a bit higher. We’ve seen worse though, agreed? Confidence: Low-Medium
