SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1136 AM CDT Wed Mar 19 2025 Valid 201200Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm development will be possible on Thursday in parts of the Mid-Atlantic and northern Rockies. A severe threat is not expected. ...Synopsis... A mid-level trough will traverse the Rockies as a second upper trough ejects into the Atlantic tomorrow (Thursday). A surface cold front will accompany the East Coast trough, immediately preceded by marginal low-level moisture (e.g. low 50s F surface dewpoints). Scant buoyancy, driven by the meager low-level moisture, may encourage the development of a few thunderstorms from the Mid Atlantic to Carolina Piedmont region. Given relatively strong flow just above the boundary layer, strong wind gusts may occur with a few of the storms, but confidence in any appreciable severe gust coverage is too low for the addition of severe probabilities at this time. Otherwise, the only other location where lightning flashes may be observed is over the northern Rockies, where a plume of cold temperatures aloft, associated with the western trough, may promote enough buoyancy (albeit scant) to support a few thunderstorms. ..Squitieri.. 03/19/2025
