Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sat Apr 19 2025 00:41:44 ACUS01 KWNS 190041 SWODY1 SPC AC 190040 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0740 PM CDT Fri Apr 18 2025 Valid 190100Z - 191200Z ....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE SOUTHERN PLAINS TO THE MID MISSISSIPPI VALLEY... ....SUMMARY... Severe thunderstorms remain possible from parts of the southern Plains northeastward through the mid Mississippi Valley tonight. Large to very large hail should be the main hazard, especially across the southern Plains where storms will be more concentrated. ....01z Update... Extensive cloud cover has developed within broad southwesterly flow from northern Mexico, northeast across the southern Plains into the Mid-MS Valley region. This has suppressed warm-sector temperatures across the southern Plains and the synoptic front has surged a bit farther south than earlier expected. Net result is significant CINH persists across the southern Plains and surface-based convection has struggled to develop. 1km flow is expected to strengthen across the southern Plains later this evening and this should aid elevated convection north of the cold front that currently extends from near LBB-north of SPS-near SGF. 00z sounding at OUN remains quite capped, but inhibition is notably weaker downstream from SGF to ILX. Latest radar data suggests a gradual increase in elevated convection across the eastern TX Panhandle into far western OK. This activity should gradually expand through the late-evening into the overnight hours. Large hail is the primary risk with these elevated storms Otherwise, some severe risk remains with any frontal convection that evolves overnight downstream across the Mid-MS Valley into western IN. ...Darrow.. 04/19/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
