LONG TERM /SUNDAY THROUGH THURSDAY/... A strong ridge of high pressure will stay in place Sunday through Wednesday. Heat and high humidity will be the main story through these four days.

Hmmmm Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 224 PM EDT Thu Jun 19 2025 .SYNOPSIS... Heat and humidity continue ahead of a potent cold front that looks to cross the region. The front will bring a widespread risk of severe weather to the area with damaging winds, large hail, and heavy rainfall as the primary concerns. Drier and less humid Friday into Saturday as high pressure builds into the region. A prolonged period of excessive heat is expected Sunday into the middle part of next week. && .NEAR TERM /THROUGH TONIGHT/... As of 18Z/2 PM EDT, a solid line of thunderstorms was developing rapidly along a prefrontal trough. This line, fueled by convergence along the trough and height falls ahead of an approaching short wave, will strengthen as it moves east into an increasingly unstable airmass. Shear is modest at 30-35 kts but these speeds extend through nearly the entire troposphere, and when coupled with high PWs and steepening low-level lapse rates is very favorable for numerous damaging wind gusts. Transient supercell structures are possible embedded within this line, but more so heading into the late afternoon and evening with any secondary development along the synoptic cold front as it approaches. Shear aloft will increase during this time. Be aware that there may be more than one round of strong storms through this evening.
