FORECAST IN DETAIL

Although it’s October, prepare to sweat again. Increasingly muggy, summery conditions are with us today and tomorrow. Temperatures may go down with rain chances by Sunday, but humidity sticks with us. We need the rain and a change in pace from this weather. Summer could return again later next week, though — stay tuned.

Today (Friday): Sunshine should dominate over any periodic clouds, but we may sweat just a bit in the moderate mugginess (dew points 60 or higher). High temperatures in the low to mid-80s — about 10 degrees above average — could feel like upper 80s during the midafternoon hours. South-southwesterly breezes should stay light, around 5 mph. Sorry if you wanted more refreshment! Confidence: High

Tonight: The sun is now setting well before 7 p.m., and temperatures follow the sun downward. Evening temperatures into the 70s are still a bit muggy. Clouds may mix with stars at times. Breezes out of the south should remain nearly calm. Low temperatures settle to around 60 degrees outside of the Beltway, which is perhaps mid-60s downtown. Confidence: Medium-High

Tomorrow (Saturday): It will continue warm, and perhaps a tad muggier. Not many clouds are expected to give us cooling shade. South winds around 10 mph are possible later in the afternoon. That might feel good! Highs temperatures may hover in the 82 to 88 degree range, by and large. Heat index values around 90 cannot be ruled out either! Confidence: High

Tomorrow night: We should remain dry into the evening, but early-morning hours may bring a 30 percent shower chance before dawn. We stay warm and very muggy, only dipping into the upper 60s to mid-70s. Oof! South-southwesterly winds around 10 mph are responsible for this warm and muggy air. Confidence: Medium-High

A LOOK AHEAD

Sunday: Clouds may dominate, streaming in ahead of a cold front to the west and from the Gulf of Mexico ahead of Nate. Showers could pop up almost anytime, and some could be heavy. Try to plan any outdoor activities early or late, but even they may turn slightly damp. High temperatures may not get above the mid-70s north and west of town, with spots to the south possibly seeing low 80s. Very muggy conditions are bolstered by moist south-southwesterly breezes near 10 mph at times. Confidence: Medium

Sunday night: Showers may continue. Another surge of rain or periodic rain is possible. Upper 60s to mid-70s may again be as low as we get before dawn. And, yep, still very muggy with dew points above the “tropical” 70 degree threshold for most of the region. Confidence: Medium

Clouds, mugginess, and some dampness may rule Columbus Day (Monday) but the chance for steadier rain and perhaps even a tropical downpour? Our dry region won’t say no! Steamy mid-70s to perhaps low 80s (if we see more sunshine) appear possible. Regret it may not be a holiday for outdoor activities this time. Confidence: Low-Medium

Warmth may surge again on a sunnier Tuesday, with high temperatures again into the 80s. Perhaps even some mid to upper 80s if the wind direction ends up being juuuuust right. Stay tuned for how warm it might get. And it still may be muggy, combining with high dew points to create heat index values around 90; it’s not out of the question. A slight chance of a shower can’t be ruled out, either. Confidence: Low
