Wednesday digit — 8/10: They can't all be perfect 10s like yesterday, but today is perfectly nice even if several degrees warmer.

What's next? Quite warm Thu-Fri with increasing humidity. Some scattered showers and a storm could come through late Thursday afternoon or evening.

We've got the full forecast through the weekend at capitalweather.com and the Capital Weather app.

Another superb evening to be out and about as temps dip through the 70s on the way to lows mid-50s to low 60s.

Still sunny Wednesday, though humidity creeps up a bit and highs again surge into the 80s.

We don't hand out many 10/10s, but Tuesday earns one. ☀️

Sunshine. Low humidity. Highs 75–80. Just about perfect.

Then warmth and humidity make a comeback, with temperatures potentially flirting with 90 Thursday and rain chances later in the week.

A little taste of fall today and Tuesday, then another surge of summerlike air later week.

But it looks like we could see an extended stretch of cooler weather as we say goodbye to astronomical summer:

A cooler pattern could arrive next week, bringing DC a better chance for early-autumn weather after another surge of late-season heat.

Surely DC is done with 90-degree heat by now... right?

Maybe not. After 50 days at or above 90 this year, there are several chances to add to the tally later this week.

The good news: A more decisive cooldown may be coming next week.
