MD 2019 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EXTREME NORTHEAST KS INTO CENTRAL/NORTHERN MO AND WESTERN IL
Mesoscale Discussion 2019 NWS Storm Prediction Center Norman OK 0516 PM CDT Tue Aug 27 2024 Areas affected...Extreme northeast KS into central/northern MO and western IL Concerning...Severe potential...Watch unlikely Valid 272216Z - 280015Z Probability of Watch Issuance...20 percent SUMMARY...Isolated damaging gusts and hail are possible into early evening. DISCUSSION...Isolated thunderstorms have developed from south/southeast of Kansas City into northern MO. The environment across this region is quite warm, moist, and unstable, with MLCAPE of 2500-4000 J/kg in place. However, deep-layer flow and vertical shear are generally weak, which should tend to limit storm organization. Given the favorable instability and rather steep low/midlevel lapse rates, the strongest updrafts could briefly pose some hail threat, though localized downbursts may become the most prominent hazard with time. This isolated severe threat may persist into early evening. ..Dean/Gleason.. 08/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ILX...LSX...DVN...SGF...DMX...EAX...TOP...

MD 2020 CONCERNING SEVERE THUNDERSTORM WATCH 658... FOR NORTHEAST IL INTO EXTREME NORTHWEST IN/SOUTHWEST MI
Mesoscale Discussion 2020 NWS Storm Prediction Center Norman OK 0624 PM CDT Tue Aug 27 2024 Areas affected...Northeast IL into extreme northwest IN/southwest MI Concerning...Severe Thunderstorm Watch 658... Valid 272324Z - 280100Z The severe weather threat for Severe Thunderstorm Watch 658 continues. SUMMARY...The severe threat will spread southeastward through early evening. DISCUSSION...A supercell has developed across far northeast IL, with reports of severe wind gusts and hail up to golf ball size thus far. Large to extreme instability will continue to support vigorous updrafts early this evening. Deep-layer shear becomes increasingly modest with southward extent, but will remain locally enhanced near a lake-enhanced surface boundary draped northwest to southeast across the Chicagoland vicinity. The ongoing supercell may propagate southeastward near this boundary, with a continued threat of large hail and severe/damaging gusts. There is some potential for additional development near the trailing outflow, with increasing cumulus noted in Kane County. Depending on the number and proximity of storms that develop early this evening, some upscale growth into a southeastward-moving cluster will be possible with time. Downstream watch issuance is possible if a severe threat begins to approach northwest IN/southwest MI. ..Dean/Gleason.. 08/27/2024 ...Please see www.spc.noaa.gov for graphic product...
