Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Scattered severe thunderstorms will continue to develop through the evening across south-central into southeast Wisconsin. Organized storms, including a few supercells, will pose a risk for mainly large hail and damaging gusts, but a brief tornado cannot be ruled out. The severe thunderstorm watch area is approximately along and 45 statute miles north and south of a line from 15 miles southwest of Madison WI to 50 miles northeast of Milwaukee WI.

MD 0551 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR NORTHERN AND CENTRAL ILLINOIS
Mesoscale Discussion 0551 NWS Storm Prediction Center Norman OK 0758 PM CDT Sat Apr 27 2024 Areas affected...Northern and central Illinois Concerning...Severe potential...Watch likely Valid 280058Z - 280200Z Probability of Watch Issuance...80 percent SUMMARY...Severe threat to increase through the rest of the evening. A Watch downstream of WW150 will likely to be needed. DISCUSSION...A line of thunderstorms is advancing north and eastward across southern Iowa into northeastern Missouri this evening. This line will eventually move into portions of northern and central Illinois, with potential for additional thunderstorm development out ahead of this line. Ahead of this ongoing activity, temperatures remain in the mid 70s with dew points in the low to mid-60s. MUCAPE around 1500-1700 J/kg is observed in objective analysis data and sounding data from the 00z RAOB from ILX. Marginal deep layer shear around 30-35 kts suggests the main threats will be damaging wind and hail. Ahead of the line, more discrete development aligned with the low-level jet axis moving across central Illinois may pose the risk of a tornado if this activity continues to mature, though low-level lapse rates may weaken and there is uncertainty regarding this scenario. ..Thornton/Smith.. 04/28/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0550 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR SOUTHERN PLAINS
Mesoscale Discussion 0550 NWS Storm Prediction Center Norman OK 0730 PM CDT Sat Apr 27 2024 Areas affected...Southern Plains Concerning...Severe potential...Tornado Watch likely Valid 280030Z - 280130Z Probability of Watch Issuance...95 percent SUMMARY...Tornado watch will be issued soon across the southern Plains from northwest TX across much of OK. DISCUSSION...Leading edge of large-scale ascent is spreading across the southern high Plains early this evening. Agitated boundary-layer cu field is deepening along the dryline over TX, indicative of the approaching trough. Convection is expected to increase in areal coverage into the southwest flank of ongoing southwest-northeast MCS, then gradually shift east. 00z sounding from OUN exhibited very strong shear (400m2/s2 0-3km SRH) with MLCAPE around 2300 J/kg, though slightly capped. Supercells and thunderstorm clusters are expected to continue, and increase in areal coverage later this evening as the trough shifts east. New tornado watch is warranted. ..Darrow/Smith.. 04/28/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TSA...FWD...OUN...SJT...LUB...AMA...
