We’ve eased back into 90F+ weather today with plenty of sun and a bit of a breeze to keep the air mixed. Humidity levels are up there too, with dew points ranging from the mid-60s to near 70, providing heat indices up into the upper 90s. On all counts, this is about as low as we’ll see in the coming period. If you’re longing for some outdoor time, you might want to take in as much as possible this evening!
Through Tonight: We may see some increase in clouds this evening, with more of that into the night. We’ll have to watch showers and storms to the north and see how well they hold together headed this way. Models don’t suggest much other than some showers after midnight, but I wouldn’t be surprised if a few storms worked in, even before then. Still, odds are not super high (30%). With dew points near or above 70, it’s a toasty one. Lows only reach the near 70 to the mid-70s, and maybe even upper 70s downtown, especially if no rain comes through to “cool” us off.
Tomorrow (Tuesday): There should be more clouds tomorrow than today, with the highest concentration probably in the morning. As the day wears on, we see more and more breaks, but also increased risk of some showers and storms as that daytime heating goes to work. Highs should reach the low-to-mid 90s, mainly mid-90s with fewer clouds. Any storms should be isolated to scattered, and there’s about a 40% chance of ‘em. However they could produce heavy downpours and even some severe weather.
Weather conference: Looking to beat the heat this weekend? Come on up to BWI for the American Weather Conference (a continuation of prior years’ Eastern U.S. Weather conference). Speakers on Saturday include Paul Kocin (NOAA), Brian LaSorsa (NWS Balt/Washington), Brad Panovich (WCNC-TV), Bill Read (National Hurricane Center) and Mike Smith (AccuWeather). If you’re free on Friday there are two workshops, one of which will feature CWG’s own Wes Junker. We’re offering a cheaper fare ($100) for CWG viewers.
