SPC Feb 9, 2023 Day 4-8 Severe Weather Outlook

LIVE MAP (ABOVE) ... Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0359 AM CST Thu Feb 09 2023 Valid 121200Z - 171200Z ...DISCUSSION... ...Day 4/Sunday... Severe thunderstorms are unlikely with a cold front having exited Florida into the Atlantic and across the eastern Gulf of Mexico. ...Days 5-6 Monday/Tuesday... A low-latitude upper-level trough is expected to move east-northeastward over the southern Plains toward the Midwest by Tuesday. After a late-week frontal intrusion across the Gulf of Mexico, it appears that the opportunity for appreciable air mass modification and significant low-level moistening will be limited. Regardless, some potential for a few strong/severe thunderstorms may exist Monday across south-central/southeast Texas, and possibly eastward to parts of the middle Gulf Coast/Lower Mississippi Valley on Tuesday. 15% severe probabilities are not currently warranted. ...Days 7/8 Wednesday/Thursday... Early indications are that severe-weather potential may increase with the approach of a secondary upper-level trough, potentially including parts of the ArkLaTex, Lower Mississippi Valley, and Mid-South. However, considerable uncertainty exists with the magnitude/primary regional locations of this currently speculative severe potential. Read more CHECK UPDATE ZOOM GRAPHIC
