007 ACUS01 KWNS 120035 SWODY1 SPC AC 120033 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0733 PM CDT Tue Jun 11 2024 Valid 120100Z - 121200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST COLORADO...SOUTH TEXAS...AND SOUTH FLORIDA... ...SUMMARY... Isolated strong storms are possible across south Florida, southeast Colorado and south Texas for a few more hours this evening. ...TX... The Slight risk (level 2 of 5) has been removed and the Marginal risk (level 1 of 5) trimmed to encompass ongoing convection. Overall storm organization has been messy and struggling to maintain severe intensity within a weakly unstable and modestly sheared environment. A stronger supercell was noted around 00z near the Rio Grande, but strong outflow shifting southwest will likely have deleterious effects on any further convection developing near the River. Nevertheless, a strong storm or two producing locally gusty winds and hail will be possible into the early overnight hours across parts of south TX. ...FL... The Marginal risk (level 1 of 5) continues across south FL this evening. A few weakly rotating storms have been noted offshore, with one more recently over the Everglades. A brief tornado or two will be possible for another couple of hours this evening. ...CO/NM... The Marginal risk (level 1 of 5) has been trimmed and is confined to ongoing convection across southeast CO. Isolated gusty winds and hail main continue with this activity for another few hours this evening before weakening. ...Upper Midwest... Severe potential is expected to remain low the remainder of the evening/overnight. Very weak instability across the region is unlikely to sustain severe convection and overall coverage of storms will be low. ...Mid-Atlantic... Isolated showers and thunderstorms will meander over northeast NC and far southeast VA the next few hours. However, very weak instability and low thunderstorm coverage will preclude severe potential. ..Leitman.. 06/12/2024 $$
