MD 0249 CONCERNING TORNADO WATCH 52...54...55... FOR ILLINOIS AND SOUTHEAST MISSOURI
Mesoscale Discussion 0249 NWS Storm Prediction Center Norman OK 0547 PM CDT Sun Mar 15 2026 Areas affected...Illinois and southeast Missouri Concerning...Tornado Watch 52...54...55... Valid 152247Z - 160015Z The severe weather threat for Tornado Watch 52, 54, 55 continues. SUMMARY...Severe squall line is propagating steadily east this evening. Damaging winds are expected, along with a risk for a few tornadoes. DISCUSSION...Mature squall line is propagating east at roughly 30-35kt across central IL into southeast MO. This LEWP is likely producing damaging winds, and several bow-head type circulations are evident along the leading edge of the linear MCS. Air mass is not particularly unstable, but VWX and PAH vad winds exhibit more than 300 0-3km SRH, along with strong speed shear. In addition, intense midlevel height falls favor this strongly forced band of convection to advance into western portions of IN shortly after 01z. ..Darrow.. 03/15/2026 ...Please see www.spc.noaa.gov for graphic product...

A few tornadoes possible Scattered damaging winds likely with isolated significant gusts to 75 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorms should continue to develop this afternoon while posing a threat for scattered severe/damaging winds and a few tornadoes. A greater wind threat, with peak gusts up to 65-75 mph, may exist if thunderstorms can form into a line along/ahead of a cold front over the next several hours. Isolated severe hail may also occur with the strongest cores. The tornado watch area is approximately along and 75 statute miles east and west of a line from 40 miles north northwest of Alton IL to 40 miles west southwest of West Plains MO. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0248 CONCERNING SEVERE POTENTIAL...WATCH NEEDED SOON FOR NORTHEAST ILLINOIS-NORTHERN INDIANA-SOUTHWEST LOWER MICHIGAN
Mesoscale Discussion 0248 NWS Storm Prediction Center Norman OK 0516 PM CDT Sun Mar 15 2026 Areas affected...Northeast Illinois-Northern Indiana-Southwest Lower Michigan Concerning...Severe potential...Watch needed soon Valid 152216Z - 152315Z Probability of Watch Issuance...95 percent SUMMARY...Severe Thunderstorm Watch will likely be issued soon for portions of northeast Illinois, northern Indiana, and southwest Lower Michigan. DISCUSSION...Leading edge of strongly forced squall line is advancing steadily east across western/northern IL. While low-level moisture is somewhat lacking downstream, with upper 40s/lower 50s surface dew points, cooling/moistening midlevel profiles favor weak destabilization over the next few hours. Strong shear supports damaging winds, and perhaps a brief tornado, with this forced line of convection and a Severe Thunderstorm Watch appears warranted. ..Darrow/Smith.. 03/15/2026 ...Please see www.spc.noaa.gov for graphic product...
