Today’s Daily Digit

A somewhat subjective rating of the day’s weather, on a scale of 1 to 10.

10
Whoa! Even I admit that temps near 80 plus low/no humidity is amazing for August. Don’t sunburn though!

Express Forecast

Today: Mainly sunny, comfortable. Highs: 76-82.

Tonight: Just a few clouds. Chilly? Lows: Near 50 to near 60.

Tomorrow: Another nice one! Highs: Mid-80s.

Sunday: Partly sunny. PM storm? Highs: Mid-80s to near 90.

FORECAST IN DETAIL

Temperatures and humidity remain reduced for quickly selling you on the fact that you need to get outdoors. The getting is good! At least until Saturday night and into Sunday, when mugginess and maybe some rain threats arrive back in the region. Next week features more typical weather with warmer, muggier air, and the somewhat constant chance of a brief shower or storm. For now, slather on that sunscreen and enjoy the sunshine and our still-warm waterways which are primed for swimming.

nice day
Today (Friday): Blue skies are to be enjoyed! (Using sunscreen of course.) Though even with plentiful sunshine our dry, comfortable day with low-w-w humidity levels may only top out in the upper 70s to low 80s most spots! We may even be able to feel a refreshing west and northwest breeze around 5 mph. Should winds align for long out of the due west, we could warm a few additional degrees by 6 p.m. Confidence: Medium-High

Tonight: We continue to enjoy low humidity overnight. That aspect to this air mass allows temperatures to drop quickly. If skies remain clear, and winds remain calm (but could sporadically blow out of the southwest), we could see a couple record low temperatures set in the region. Overall, most of us should end up in the 50s before dawn. Perhaps some upper 40s well west of D.C., in the Blue Ridge, but downtown itself hovers around 60. Confidence: High

Tomorrow (Saturday): It’s still comfortable, but a bit more summery. Humidity rises just a notch, along with a rise of our high temperatures–mid-80s are likely by late afternoon. Skies should remain mostly sunny with just perhaps a few periodic clouds. After applying sunscreen, I encourage everyone to find a beach, pool, or park. Or just run or bike around the city? Still hard-to-beat August weather. Breezes lightly blow out of the southwest around 5 mph by afternoon. Confidence: Medium-High

Tomorrow night: Skies remain fairly starry until nearer dawn when clouds want to make their move. Timing is a bit uncertain, but the trend after midnight is for an increase in cloud cover. Some showers to our north have a 10% chance or so of infiltrating the region by sunrise, but we’ll watch it. Thanks to the increasing cloud cover and south winds around 5 mph, low temperatures are warmer–in the 60s to near 70 downtown. Confidence: Medium

Sunday: Could be a bit muggier and also warmer. Much of the day is dry under partly cloudy skies, but some shower or storm risk may become apparent in the afternoon (30-40% chance). How quickly we cloud up and with how many clouds should determine high temperatures. There’s a shot we could make a run at 90 if it stays sunny long enough, with a currently expected range in the mid-80s to near 90. Confidence: Low-Medium

A LOOK AHEAD

Sunday night: We may continue to have more clouds than visible stars–and a 30% threat of showers or a few thundershowers around dinner time, then decreasing chances of rain after midnight. By just before dawn, low temperatures get nice and chilly (ha), into the upper 60s to around 70 (downtown). Muggy is reclaiming our region. Confidence: Medium

Our Monday may start out a sunnier note, but cloud debris from storms that originated in the Midwest could cloud up skies by afternoon. As clouds approach, shower and thunderstorm chances rise to around 30%. Perhaps 40% chance into and through the evening. Highs temperatures should make it into the mid-80s to near 90 zone again. It could also be a bit sweaty and sticky. Confidence: Medium

Tuesday is more of the same, with perhaps more clouds than sun and a chance of showers and storms. Chances appear a bit higher (around 50%), so we stand a better chance at watering the gardens. But remember if you are outside and hear thunder, take shelter indoors please. Muggy high temperatures likely top out into the mid-to-upper 80s by late afternoon. Less sun than currently expected may mean subtract a couple degrees from this. Confidence: Low-Medium
