       With Fred out of here, summertime heat swooped in to give us a big hot hug. D.C. rose above 90 degrees for the first time since Saturday, with heat indexes closing in on 100 at times. This heat and humidity are likely to fuel some showers and storms into the evening and night. More rain is on the way tomorrow. Some could be heavy and lead to flooding.

       Through Tonight: Showers and storms are possible into the evening and overnight. The heaviest should tend to stay south of the city until later at night, but it could be close. Late night, rain will cover more of the area. Any shower or storm could be quite heavy, possibly causing flooding. Remember to turn around, do not drown. This is especially important at night. Lows will be in the low and mid-70s.

       Tomorrow (Friday): Let’s start with the good news. Temperatures should cool down, and we may struggle to pass 80 degrees. Of course this is because there are a lot of clouds and rain around. It should not rain all day, but it could still be wet throughout. Some storms could be strong and drop heavy rain, potentially leading to flooding. It could be muggy, too.

       More rain: While the rainfall forecast above ranges from about a half-inch north to more than two inches south, any spots that see repeated showers and storms pass by could surpass the numbers shown and in a short time. The air mass is chock full of moisture and ready to unleash it as a cold pocket aloft moves in and Tropical Storm Henri blocks its forward movement a bit. Rainfall rates of one to two inches per hour is possible, so any slow-moving activity can be problematic.

       Through Wednesday, Washington has seen 5.69 inches of rain. That is about two inches above average for the entire month, and 12th most month-to-date.
