Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0227 PM CDT Tue Apr 29 2025 Valid 011200Z - 021200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE LOWER GREAT LAKES REGION SOUTHWESTWARD TO TEXAS... ...SUMMARY... Strong/locally severe thunderstorm development is expected from central Texas into the Mississippi and Ohio Valleys northward to the Great Lakes Thursday. Thunderstorms will pose a risk for strong to severe winds and hail. ...Synopsis... A mid-level vort max forecast to be moving eastward across the Ozarks toward the Ohio Valley early Thursday will be followed by a second trough digging southeastward across the north-central CONUS. As this occurs, weak low pressure initially progged to reside over the Missouri vicinity will gradually deepen as it shifts east-northeastward into the Midwest through the day, and then across Lower Michigan and into Ontario overnight. A trailing cold front is forecast to shift gradually southeastward across the Midwest/Mid Mississippi Valley/southern Plains through the period. ...Lower Great Lakes southwestward to Texas... Thunderstorms are forecast to be ongoing over -- and just west of -- portions of the MRGL risk area at the start of the period, and this initial convection complicates the forecast with respect to areas where diurnal destabilization may be sufficient to fuel new/vigorous convective development. In general however, a midday/early afternoon increase in storms is expected across the Lower Ohio and Mid Mississippi Valley, ahead of a slowly advancing cold front, and potentially in the vicinity of remnant outflow farther south into the Lower Mississippi Valley area. Modest shear is forecast across the lower Mississippi Valley area, and westward into Texas where a few later-afternoon storms may develop, which should limit overall risk to locally stronger storms. Hail/wind would be the primary risks. Farther north into the Midwest, stronger flow aloft is expected, but also likely weaker instability. While later inclusion of a SLGT risk area may be needed across a portion of this area, at this time uncertainty precludes that. Generally, pre-frontal convection developing during the afternoon may pose risk for severe-caliber wind/hail locally. Risk should gradually diminish during the evening as storms nocturnally weaken. ..Goss.. 04/29/2025 Read more

MD 0603 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTHERN IL/IN INTO PORTIONS OF WESTERN/NORTHERN KY
Mesoscale Discussion 0603 NWS Storm Prediction Center Norman OK 1252 PM CDT Tue Apr 29 2025 Areas affected...southern IL/IN into portions of western/northern KY Concerning...Severe potential...Watch likely Valid 291752Z - 291915Z Probability of Watch Issuance...80 percent SUMMARY...Severe thunderstorms with a risk for damaging gusts and isolated hail are expected across portions of the Lower Ohio Valley through the afternoon. A new watch will likely be needed by 19z. DISCUSSION...A cluster of convection across southeast MO will continue to shift east/northeast through the afternoon. While this activity is in a relative minimum with regards to intensity compared to earlier today, the downstream airmass across portions of the Lower Ohio Valley continues to destabilize amid mid/upper 60s F dewpoints and temperatures in the 80s F. Some re-intensification of the storm cluster is possible as it encounters this airmass. Additional thunderstorm development is also possible near the Ohio River in southern IN. A cluster of cumulus has been deepening across this area, where outflow from earlier convection may be providing focus for new development. Steepened low-level lapse rates, moderate instability, and effective shear increasing to greater than 35 kt should favor organized cells/clusters capable of damaging gusts and isolated hail. A new watch downstream from Severe Thunderstorm Watch 187 will likely be needed in the next hour or so. ..Leitman/Hart.. 04/29/2025 ...Please see www.spc.noaa.gov for graphic product...
