SPC Feb 9, 2023 0700 UTC Day 2 Convective Outlook

LIVE MAP (ABOVE) ... SPC 0700Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1257 AM CST Thu Feb 09 2023 Valid 101200Z - 111200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE SOUTHEAST STATES... ...SUMMARY... A few severe thunderstorms are possible across the Southeast on Friday including northern Florida, southeast Alabama and southern/eastern Georgia into southern South Carolina. ...Southeast States... A positive-tilt upper-level trough will move east-southeastward from the southern Plains toward the Lower Mississippi Valley through Friday night. A preceding cold front will be located from the coastal Mid-Atlantic States southwestward across the Carolinas into Georgia/northern Florida Friday morning. A moist air mass with 60s F surface dewpoints is expected to be in place ahead of the front, especially across Florida into parts of Georgia/southern South Carolina. While the boundary layer will be relatively moist, overall destabilization is currently expected to be muted by some lingering cloud cover as well as weak mid-level lapse rates. Even so, weak destabilization in the presence of 40+ kt effective shear may be conducive for a few severe thunderstorms through Friday afternoon, which could include locally damaging winds and/or a tornado. ..Guyer.. 02/09/2023 Read more CHECK UPDATE ZOOM GRAPHIC
