MD 0260 CONCERNING SEVERE THUNDERSTORM WATCH 56... FOR SOUTHEAST LOWER MICHIGAN...NORTHEAST INDIANA...NORTHWEST OHIO
Mesoscale Discussion 0260 NWS Storm Prediction Center Norman OK 1114 PM CDT Sun Mar 15 2026 Areas affected...Southeast Lower Michigan...northeast Indiana...northwest Ohio Concerning...Severe Thunderstorm Watch 56... Valid 160414Z - 160615Z The severe weather threat for Severe Thunderstorm Watch 56 continues. SUMMARY...Isolated damaging wind risk continues with progressive squall line. However, a new watch is not currently anticipated. DISCUSSION...Strongly forced band of pre-frontal convection is propagating northeast across northeast IN/southern Lower MI and extreme northwest OH. Boundary layer air mass has gradually recovered into southeast MI over the last few hours which is contributing to weak buoyancy, immediately ahead of this convection. However, updrafts appear to be weakening a bit as lighting with the northern portions of the squall line is decreasing, and the linear nature of this activity is becoming more diffuse with time. Given the current trends a new watch is not currently anticipated. ..Darrow.. 03/16/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CLE...DTX...IWX...GRR...

MD 0256 CONCERNING TORNADO WATCH 59... FOR FAR NORTHWESTERN ALABAMA AND SOUTH CENTRAL MIDDLE TENNESSEE
Mesoscale Discussion 0256 NWS Storm Prediction Center Norman OK 1002 PM CDT Sun Mar 15 2026 Areas affected...far northwestern Alabama and south central Middle Tennessee Concerning...Tornado Watch 59... Valid 160302Z - 160430Z The severe weather threat for Tornado Watch 59 continues. SUMMARY...Tornado risk increasing. DISCUSSION...A discrete supercell has shown persistent rotation and strengthening over the last 30-45 minutes near the TN/AL state line. A second cell has also shown persistent rotation to the north of to the north of the TN state line. This is on the southern end of a cluster of cells ahead of the main squall line back to the west on the edge of the 60 F dew points. Within this region, STP around 2 is analyzed in surface objective analysis, with VAD profiles from KBNA and KGWX showing large low-level curvature in hodographs. This corridor will pose a relatively higher risk for tornadoes over the next 1-2 hours given the favorable shear and thermodynamic environment. ..Thornton.. 03/16/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 0254 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR SOUTHEAST LOUISIANA...SOUTHERN MISSISSIPPI...AND SOUTHWESTERN INTO WEST-CENTRAL ALABAMA
Mesoscale Discussion 0254 NWS Storm Prediction Center Norman OK 0828 PM CDT Sun Mar 15 2026 Areas affected...southeast Louisiana...southern Mississippi...and southwestern into west-central Alabama Concerning...Severe potential...Tornado Watch likely Valid 160128Z - 160330Z Probability of Watch Issuance...80 percent SUMMARY...Damaging wind and tornado risk to increase this evening. DISCUSSION...A broken line of thunderstorms continues near a cold front sagging southward and east across central LA into southeast Texas. Further east ahead of the front, attempts at development are starting to occur across southern Louisiana as MLCIN has begin to erode over the last hour. It is likely that ongoing convection will move downstream, with additional development possible ahead of this across southern Louisiana into southern Mississippi. MLCAPE around 1000-2000 J/kg will overlap with deep layer shear around 40 kts to support supercells ahead of the main line and more clustered/mixed mode/line embedded supercells closer to the cold front. Primary risks would be for damaging winds and tornadoes, though some instances of hail could occur with discrete supercells. A watch will be needed soon to cover this threat. ..Thornton/Smith.. 03/16/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BMX...MOB...JAN...LIX...LCH...
