Valid 222027Z - 222230Z The severe weather threat for Tornado Watch 41 continues. SUMMARY...Damaging gusts and perhaps a brief tornado remain possible across tornado watch 41. DISCUSSION...A broken line of convection has shown some better organization and modest intensification over the past 30-45 minutes, particularly as the line moves into east-central IL. Somewhat better heating and dewpoints in the upper 50s to near 60 F is likely responsible for convection become more surface-based compared to earlier in storm-scale evolution. A couple of measured severe gusts were noted just north of St. Louis, and damaging wind potential will continue across the remain of tornado watch 41.=20 Some veering of low-level winds is noted in surface observations across southern IL. However, some southeasterly low-level winds are still noted closer to central IL nearer to the warm front and a weak surface low/triple point. Given the magnitude of low-level shear, a locally greater chance of a brief tornado may exist between the I-70 and I-64 corridors.=20 Severe potential should wane with eastward extent into portions of western KY and IN and a downstream watch is not currently anticipated. ...Leitman.. 02/22/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-W6pPh0OhuqdlXQb9i0UQN1ob9WVhfgfyJ32NfWZOnUH_qUOOobzuvYxzSEliGJfcgsGr6qRz= FaDlxDeclXpBr4Xxgg$ for graphic product...
