FORECAST IN DETAIL
Yesterday D.C. tied the total for last year when it comes to days at or above 95 degrees, and those 24 instances are more than two times normal for a year around here. It’s possible we’ve got another today as well. Yep, it’s more of the same hazy sunshine giving way to isolated or scattered afternoon showers and storms. Add in high heat and humidity and you’ll probably want to limit your outdoor time during the midday, unless you’re near a pool or at the beach.
Today (Saturday): We should see partly to mostly sunny skies early with more and more bubbling clouds as the day progresses. Those clouds probably, as in recent days, give way to isolated or scattered showers and t’storms (30% chance). Highs look to reach the low-to-mid 90s across the area. Humidity is high, and that means heat indices again near 100 in the afternoon. Confidence: Medium-High
Tonight: Isolated to scattered showers or t’storms may continue through the evening (30-40% chance), but they’ll probably want to diminish as we get past sunset, as they typically do with the loss of daytime heating. Otherwise, we’re partly cloudy through the night. With dew points still near or above 70, lows in the low-and-mid 70s are pretty likely. Confidence: Medium-High

Tomorrow (Sunday): We keep the broken record going on Sunday, as morning sunshine bakes us nicely before clouds and thunderstorm chances increase. There’ll be more winds aloft as well, so storms might pack a bit more punch. The main question for now is if the front and lift out ahead of it will push close enough during the day to maximize the severe storm threat. For now, I tend to lean toward it coming in a bit late for the worst of storminess. However, we’ll still run the risk for isolated damaging winds and hail in any storms during the late day. Highs may be a bit cooler (around 90) if we get clouds and storms in early enough, but otherwise it’s another day shooting for the mid-90s. Confidence: Medium
Tomorrow night: Odds of rain might actually be best during the evening and into the overnight, about a 50-60% chance, as the front finally pushes into and through the area with showers and storms along it. Doesn’t look like a lot of rain for everyone though. The front is moving slow enough to keep us from getting too much relief in humidity, and that means lows range from near 70 to the mid-70s. Confidence: MediumA LOOK AHEAD
With the cold front heading south on Monday, we should end up with a little break in the higher heat at least. Expect partly cloudy skies, perhaps a little bluer than recent times, with less humidity and a fresher wind. There could still be an isolated shower or storm, probably mainly south of the area. Our “cooler” air mass should help keep highs in a range from the upper 80s to near 90. Confidence: Medium
Tuesday continues our nicer temperature trend, even if they’re still near or above average for this time of year. Plan on more mostly to partly sunny skies and at least tolerable humidity levels. If we’re lucky, we might not touch 90 anywhere, but I wouldn’t bet on it. Highs are mainly in the upper 80s. Confidence: Medium
