  "textContent": "MD 0997 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EAST-CENTRAL ILLINOIS INTO WEST-CENTRAL OHIO\n\n\n\n\n    Mesoscale Discussion 0997\n    NWS Storm Prediction Center Norman OK\n    0539 AM CDT Sat Jun 06 2026\n\n    Areas affected...East-central Illinois into west-central Ohio\n\n    Concerning...Severe potential...Watch unlikely\n\n    Valid 061039Z - 061245Z\n\n    Probability of Watch Issuance...20 percent\n\n    SUMMARY...Isolated large hail and damaging winds are possible with a\n    marginally organized cluster of storms. Surface heating will be\n    needed for a greater severe threat. A watch is not anticipated in\n    the short term.\n\n    DISCUSSION...A small cluster of thunderstorms has recently\n    intensified in east-central Illinois. This activity is tied to the\n    shortwave trough currently moving into the lower Great Lakes region.\n    Regional VAD data shows around 35-40 kt of 0-6 km shear. With\n    sufficient elevated buoyancy (1000-1500 J/kg MUCAPE), some storm\n    organization can be expected. Dewpoints do decrease to the the east\n    of the this cluster, however. The environment will support isolated\n    large hail and strong/damaging wind gusts. A couple of recent\n    measured gusts were near severe (54-57 mph) in Pontiac, IL. It\n    likely will be after daybreak before these storms can intensify\n    further. That said, a watch is not anticipated in the near term.\n    Observational trends will need to be monitored as surface heating\n    increases in the coming hours.\n\n    ..Wendt/Hart.. 06/06/2026\n\n    ...Please see www.spc.noaa.gov for graphic product...\n\n    ATTN...WFO...CLE...ILN...IWX...IND...LOT...ILX...\n\n    LAT...LON   40048855 40408899 40888913 41258901 41478789 41328600\n                41048416 40918377 40208379 39528446 39588642 40048855\n\n    MOST PROBABLE PEAK WIND GUST...UP TO 60 MPH\n    MOST PROBABLE PEAK HAIL SIZE...UP TO 1.25 IN\n\n\n\nRead more",
