Administrators NorthGeorgiaWX Posted November 21, 2023 Administrators Share Posted November 21, 2023 MD 2280 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR SOUTHERN MISSISSIPPI INTO PARTS OF EASTERN LOUISIANA Mesoscale Discussion 2280 NWS Storm Prediction Center Norman OK 1153 PM CST Mon Nov 20 2023 Areas affected...southern Mississippi into parts of eastern Louisiana Concerning...Severe potential...Watch possible Valid 210553Z - 210730Z Probability of Watch Issuance...40 percent SUMMARY...A few strong may produce strong gusts or even a brief tornado, but the overall threat in the near term is not expected to warrant an additional watch. DISCUSSION...Storms have aggregated into a broken line from southern MS into southeast LA, with indications of gusts winds at times. Little rotation or supercell structures have been observed in the past hour, likely due to gradually veering low-level winds and decreasing ascent overall. Effective SRH around 300 m2/s2, a moist boundary layer and 500-1000 J/kg MLCAPE still may yield a supercell, but perhaps short lived, with brief tornado potential. However, the overall threat does not appear high enough for an additional tornado watch at this time. Given the moist air mass and 40-50 kt low-level jet, convective trends will continue to be monitored for any increase in intensity overnight. ..Jewell.. 11/21/2023 ...Please see www.spc.noaa.gov for graphic product...
