FORECAST IN DETAIL

You’ll love the next few days of sunny, comfortable conditions. Into early next week, Hurricane Irma [LATEST HERE] eyes our region. However, the impacts will be substantially less than what Irma has wrought thus far or what it will do in the Southeast. Still, we will have to watch late Monday into Tuesday for possible threats of heavy rain, tidal flooding and maybe even tornadoes, or some damaging winds.

Today (Friday): This is September at its best. We’ve got low- to mid-70s for high temperatures, mainly sunny skies (sunscreen please!), and low dew points (50s!) allowing for high comfort. A light 5 to 10 mph west-northwesterly breeze should feel refreshing! Just be sure to walk on the sunny side of the street if you feel a bit cooler in these conditions. It’s refreshingly below-average even for this time of year. Confidence: High


Tonight: Partly cloudy skies, light northerly breezes around 5 mph, and pre-dawn low temperatures eyeing the upper 40s outside the Beltway (probably mid-50s downtown) — yup, fall has arrived early! Confidence: High

Tomorrow (Saturday): More autumnal bliss, or a preview at least. It’s perhaps coolest day of the weekend, too, with high temperatures holding around 70 to low 70s perhaps? But south of town could eye the mid-70s, we’ll see. Enjoy those mostly sunny skies with sunglasses and some sunscreen (at least until Columbus Day, when the sun angle finally starts getting lower!). Northerly breezes 5 to 10 mph could feel a bit nippy to our summer souls, especially in the shade! Confidence: High

Tomorrow night: It should be one of the noticeably coolest nights of late! We might even need a blanket? Low temperatures bottom out in the mid-40s (north & west cold spots) to the mid-50s downtown. Light north breezes around 5 mph may make it feel a couple degrees cooler! Skies stay clear for stargazing. Confidence: Medium-High

A LOOK AHEAD

Sunday: Sunshine should dominate over any late-day clouds that pop up, as temperatures top out in the low- to mid-70s. Northeast breezes between 5 to 10 mph aren’t anything we can’t handle. Keep your thoughts with Florida as Irma probably batters the state as it turns northward. Confidence: Medium-High

Sunday night: Breezes may calm, and clouds may move in. Low temperatures will probably hover in the 50s, regionwide. Confidence: Medium

It gets cloudier but should still be calm before the storm on Monday. High temperatures in the low- to mid-70s. Irma could throw a few late-day sprinkles and breezes our way, but stay tuned for timing. Overnight Monday appears to be our first slug of rainfall. Confidence: Medium

Rains from Irma may move up into the region, perhaps giving us a fairly wet and breezy day Tuesday. Upper 60s to low 70s may be the best we do for temperatures in that case, but it’s not certain. There’s also a chance the bulk of the rain heads southwest and west of here, with it drying over time and not being a huge deal. In either case, muggy, tropical air makes us remember the source of the air we’re dealing with. We’ll update the forecast as we get closer. Confidence: Medium
