Mesoscale Discussion 0177 NWS Storm Prediction Center Norman OK 0745 PM CDT Fri Mar 14 2025 Areas affected...northern Arkansas into southern and eastern Missouri and into southwestern and central Illinois Concerning...Tornado Watch 32... Valid 150045Z - 150245Z The severe weather threat for Tornado Watch 32 continues. SUMMARY...Hazardous weather potential -- including strong/damaging winds, large hail, and a few, possibly strong tornadoes -- continues. DISCUSSION...Latest radar loop shows a gradual change in storm character over the past hour or so across south-central Missouri in particular, where substantially more robust supercells have evolved. Development has also increased southward into northern Arkansas. The change in storm character coincides with -- and is likely resulting from -- low-level moistening which is ongoing/spreading northward with time. Storms increased substantially as dewpoints rose into the low 50s, and now mid 50s dewpoints have overspread much of southeastern Missouri and upper 50s to low 60s across northern Arkansas and into the MO Bootheel. Given the highly favorable flow field (veering and strongly increasing with height), this increase in low-level moisture will likely support corresponding increases in severe/tornado potential, including risk for strong tornadoes potential evolving with time. With storms now crossing the Mississippi River in west-central Illinois, and in the next couple of hours farther south including the St. Louis Metro area, a new Tornado Watch will likely be needed across central Illinois and possibly into western Indiana. ..Goss.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...
