 First alert meteorologist Jordan Evans. Tracking an active Sunday weather forecast across the D.C. area with temperatures climbing into the 90s. All that humidity means our heat index is high as 100 degrees once again, and that's going to set the stage for strong to severe storms as a front moves in later this afternoon. Timing for severe weather between 3 and 8 p.m. Most of it comes to an end by 9 o'clock and rain overall. Done by midnight with north winds by early tomorrow, and that'll bring in some cooler, drier conditions to start July.
