Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Tue Mar 28 2023 12:50:38 ACUS01 KWNS 281250 SWODY1 SPC AC 281248 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0748 AM CDT Tue Mar 28 2023 Valid 281300Z - 291200Z ....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PARTS OF THE GULF COAST AND SOUTHEAST STATES... ....SUMMARY... Isolated severe hail and damaging winds are expected through this afternoon across portions of the Southeast and Gulf Coast. ....Central Gulf Coast to the South Atlantic Coast... Scattered thunderstorms are ongoing along a quasi-stationary front from the northwest Gulf to southwest GA. See MCD 381 for near-term discussion along the Central Gulf Coast. The western portion of this front will accelerate southward today, while the eastern portion accelerates southeast later today into tonight. Given the degree of ongoing convection, which is largely expected to linger, the bulk of diurnal destabilization should be confined to north FL and the peninsula, with limited surface heating to the northwest. Still, some uptick in thunderstorm coverage is expected around midday along eastward-propagating outflows into southern AL/GA and north FL. Predominately westerly and modest low-level wind profiles suggest that 0-3 km SRH will remain weak. But favorable speed difference with height should still maintain effective bulk shear around 40 kt. This will support occasional mid-level rotation in the more robust updrafts and yield a threat for sporadic/isolated severe hail and damaging winds until convection shifts off the South Atlantic Coast and/or weakens towards early evening. ....Deep South TX... The remnant right-split of a pair of supercells that formed a couple hours ago within a low-level upslope flow regime just west of LRD may persist slowly southeastward this morning. A couple additional cells may develop over northeast Mexico and graze the Lower Rio Grande Valley as well. Large hail will be the primary hazard, with this threat diminishing towards early afternoon as elevated buoyancy wanes. ...Grams/Goss.. 03/28/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
