* Heat advisory through 8 p.m. and again Tuesday *

Even if you’re a fan of summer, this is about when day after day of high heat gets increasingly annoying. Today’s high was at least 98 in Washington, which we’ve now done three of the past four days, in addition to Sunday’s cool high of 97. With 97 as a baseline, we’ve now seen eight such days, which is the third most to date behind the leader, which was 12 in 2012. We’ll probably add to that tally tomorrow. We’re also at three weeks of 90-plus after today. Last year, there were only 32 total and 10 to date!

Through Tonight: We may see a quick evening storm, mainly north and west nearer high terrain, with most places not seeing anything. Toasty into tonight. Lows end up ranging from the mid-70s to low 80s as high humidity settles back in for a stay.

Tomorrow (Tuesday): Another day of partial sun, lots of heat and some haze. Highs should reach the mid-90s to around 100 across the area, and the immediate area flirts with 100 in many spots. Given the high humidity, it feels more like 105 to 110 in the afternoon. An isolated storm isn’t impossible but is rather unlikely in any one spot.

Return of the 80-degree low: After an explosion of 80-degree lows in the 2010s in D.C., they quietly disappeared for five years.

Now for their “glorious” return. Washington picked up one in June, which is very early to do so. We’ve now tallied two in this heat wave, with a third to be confirmed once we pass midnight tonight, and another likely tomorrow.

Getting to five lows of 80-plus will move the city to a tie for second most of any year, with the record seven apparently quite in reach.
