Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1110 AM CDT Fri May 02 2025 Valid 021630Z - 031200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM CENTRAL/EAST TEXAS TO THE LOWER MISSISSIPPI VALLEY AND TENNESSEE VALLEY... ...SUMMARY... Widespread strong/severe thunderstorm development is expected from parts of central and eastern Texas to the lower Mississippi and Tennessee Valleys, and into the Cumberland Plateau by evening. This includes potential for large hail and damaging wind gusts. ...TN/OH Valleys... Multiple clusters of thunderstorms are affecting parts of AR/northern MS/west TN late this morning. These storms will progress northeastward into a very moist and unstable air mass, where strong heating and dewpoints near 70F will yield afternoon MLCAPE values of 2000+ J/kg. Moderately strong westerly flow aloft will aid in convective organization, posing a risk of multicell storms and bowing line segments capable of large hail and damaging wind gusts. Southerly low-level wind are strong enough to pose a risk of a tornado or two, if one or more of the clusters can become better organized. Reference WW 209. ...OH/PA... Thunderstorms are beginning to develop across western OH along a weak cold front. This activity will increase in coverage through the afternoon, spreading northeastward across OH and into northwest PA. The strongest cells will be capable of damaging wind gusts and hail. Reference MCD #645. ...TX/LA... A convectively aided front is sagging southward across north TX this morning. The air mass along and ahead of the boundary is very moist and unstable, with forecast soundings showing steep mid-level lapse rates and at least pockets of very large CAPE (4000-5000 J/kg). Weak inhibition will lead to scattered thunderstorm development along the boundary by mid-afternoon. Low-level winds will be rather weak, but sufficient deep-layer shear will promote supercells capable of very large hail and damaging wind. Very strong anvil-level winds will aid in the large/giant hail potential. Reference MCD #646. ..Hart/Squitieri.. 05/02/2025 Read more

The air mass along and ahead of the boundary is very moist and unstable, with forecast soundings showing steep mid-level lapse rates and at least pockets of very large CAPE (4000-5000 J/kg). Weak inhibition will lead to scattered thunderstorm development along the boundary by mid-afternoon. Low-level winds will be rather weak, but sufficient deep-layer shear will promote supercells capable of very large hail and damaging wind. Very strong anvil-level winds will aid in the large/giant hail potential. Reference MCD #646. ..Hart/Squitieri.. 05/02/2025 Read more

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1110 AM CDT Fri May 02 2025 Valid 021630Z - 031200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM CENTRAL/EAST TEXAS TO THE LOWER MISSISSIPPI VALLEY AND TENNESSEE VALLEY... ...SUMMARY... Widespread strong/severe thunderstorm development is expected from parts of central and eastern Texas to the lower Mississippi and Tennessee Valleys, and into the Cumberland Plateau by evening. This includes potential for large hail and damaging wind gusts. ...TN/OH Valleys... Multiple clusters of thunderstorms are affecting parts of AR/northern MS/west TN late this morning. These storms will progress northeastward into a very moist and unstable air mass, where strong heating and dewpoints near 70F will yield afternoon MLCAPE values of 2000+ J/kg. Moderately strong westerly flow aloft will aid in convective organization, posing a risk of multicell storms and bowing line segments capable of large hail and damaging wind gusts. Southerly low-level wind are strong enough to pose a risk of a tornado or two, if one or more of the clusters can become better organized. Reference WW 209. ...OH/PA... Thunderstorms are beginning to develop across western OH along a weak cold front. This activity will increase in coverage through the afternoon, spreading northeastward across OH and into northwest PA. The strongest cells will be capable of damaging wind gusts and hail. Reference MCD #645. ...TX/LA... A convectively aided front is sagging southward across north TX this morning. The air mass along and ahead of the boundary is very moist and unstable, with forecast soundings showing steep mid-level lapse rates and at least pockets of very large CAPE (4000-5000 J/kg). Weak inhibition will lead to scattered thunderstorm development along the boundary by mid-afternoon. Low-level winds will be rather weak, but sufficient deep-layer shear will promote supercells capable of very large hail and damaging wind.
