Once we get through today, we’re staring down a fairly sunny and comfortable few days. Best yet, it’s timed to a leisurely August weekend. Yes, please! Very lucky. Just hang on through another of our repeating days of late as we close the workweek: It’s hot, humid and eventually stormy in spots. Soon we’ll trade mugginess and downpour chances for drier conditions and drier air. Get ready to spend a lot of time outdoors!
Today (Friday): Above-average heat and near-tropical humidity. At least it’s stirred with a moderate southerly breeze around 5 to 15 mph. Thunderstorm chances are fairly low, with about 20 percent of locales in our region potentially seeing something pop during the day, mainly late; however, downpours are possible, as is plentiful lightning. Pay attention to localized stream flooding if the downpour doesn’t let up after a short time. Upper 80s to perhaps a few mid-90s are possible, so dress as lightly as possible! Confidence: Medium-High
Tonight: A weak, typical summertime cold front pushes through, and rain chances may go up as the evening wears on. Be prepared for about a 50-60 percent chance of a storm during the evening, potentially in the form of at least a broken line passing through. This could be somewhat hit-or-miss, but a brief downpour is possible, as is more dangerous lightning. Low temperatures downtown try for around 70, with mostly 60s outside of the Beltway. Mugginess is trending downward, at least! Confidence: Medium
Any lingering clouds clear out as the morning progresses. Enjoy the drier air filtering in on moderate west-northwesterly breezes near 15 mph. Dew points should plummet toward the ever-so-comfortable 50-degree mark. High temperatures top out in the low to mid-80s. A hair below average, and Nice Day worthy! Confidence:
Tomorrow night: As northwesterly breezes slowly die down, a few clouds could pass by. It looks dry! Dew points creep up a little, but it still looks like we will enjoy unmuggy low temperatures in the low to mid-60s. It’s borderline, but perhaps windows can remain open, especially if you’re outside the Beltway and the deer promise to stay outside? Confidence: Medium-High
Sunday: Let’s focus on the mainly sunny skies, dry conditions and light southerly breezes — with temperatures in the mid to upper-80s. That’s about average for this time of year, and another great day to spend outdoors. Yes, dew points creep back toward the mid-60s to create a stickier afternoon, and clouds could increase a bit as well. Confidence: Medium-High
Sunday night: Clouds continue to increase, dew points are into tropical-air-mass territory, and some showers — with perhaps thundershowers embedded — may pop starting around midnight. It could be a windows-closed night with the A/C on. Predawn temperatures bottom out in the upper 60s to perhaps mid-70s inside the Beltway. Confidence: Medium
A cloudier, unsettled pattern moves in for Monday into Tuesday. Around 80 to mid-80s appears possible both days, despite clouds. A southerly flow of moderate, muggy breezes should reinforce that humid feeling through perhaps early Tuesday. A cold front could work its way through and present a clearer Tuesday afternoon, but we will see. Monday presents the highest chance of rain and storms — perhaps downpours — with rain on Tuesday appearing lighter and iffier. We’ll of course tweak the forecast, as needed, once we get a bit closer! Confidence: Medium
