ACUS03 KWNS 190724 SWODY3 SPC AC 190723 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0223 AM CDT Tue May 19 2026 Valid 211200Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Widely scattered afternoon thunderstorms are expected across the northern Rockies, portions of the southern Florida peninsula, and from the southern Plains to portions of the Southeast on Thursday. Severe storms are not expected. ...Discussion... A few thunderstorms will be possible near the upper low across Montana. Limited moisture and weak instability will limit the severe risk in this region. A stationary front will extend from far southern Texas into the Mississippi Valley and northward to the Carolinas. Scattered thunderstorms are expected along and south of the front across the Southeast and mid Atlantic. Additional afternoon thunderstorms will develop across the southern Florida peninsula with the sea breeze circulation. Storms will likely be sub severe, given weak flow/shear for organization across these regions. Across the southern High Plains, widely scattered thunderstorm activity is expected near the front and across portions of the high terrain from western Texas into eastern New Mexico/southeastern Colorado. Moisture will become more limited with northern extent in New Mexico and Colorado, with dew points in the low 50s. A few stronger storms may produce instances of strong winds and small hail. Overall, the stronger mid-level flow should remain displaced from the better moisture leading to low confidence in a more organized severe threat. ..Thornton.. 05/19/2026 $$
