A few tornadoes possible Scattered damaging winds likely with isolated significant gusts to 75 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...Severe storms will spread northeastward through early tonight, with a continued threat for a few tornadoes, damaging gusts of 60-75 mph and isolated large hail near 1 inch in diameter. The tornado watch area is approximately along and 60 statute miles east and west of a line from 25 miles north northwest of Rockford IL to 40 miles west southwest of Marseilles IL.

MD 0882 CONCERNING TORNADO WATCH 278...280... FOR PARTS OF WEST CENTRAL ILLINOIS AND NORTHEASTERN THROUGH SOUTHWESTERN MISSOURI..NORTHEASTERN OKLAHOMA AND NORTHWESTERN ARKANSAS
Mesoscale Discussion 0882 NWS Storm Prediction Center Norman OK 0755 PM CDT Tue May 21 2024 Areas affected...parts of west central Illinois and northeastern through southwestern Missouri..northeastern Oklahoma and northwestern Arkansas Concerning...Tornado Watch 278...280... Valid 220055Z - 220300Z The severe weather threat for Tornado Watch 278, 280 continues. SUMMARY...Stronger thunderstorm development, including a few supercells, may become increasingly confined to portions of northeastern Oklahoma and northern Arkansas/adjacent southern Missouri through 9-11 PM CDT. A new severe weather watch may be needed across parts of northern Arkansas soon. DISCUSSION...The cold front appears to have overtaken the dryline across western into central Missouri and northeastern Oklahoma, with little appreciable increase in thunderstorm development. Widely scattered strong storms persist, including a few supercells, but an initial corridor of drier/more stable air across parts of south central and east central Missouri into west central Illinois remains a complicating factor for maintenance of this activity through mid to late evening. A more recent flare-up of convection immediately to the southwest through northwest of St. Louis may have been aided by weakening inhibition associated with leading edge of mid-level cooling near the eastern periphery of the corridor of drier air, further complicating the maintenance of strong convection beyond the next hour or two. Strongest thunderstorm development may begin to become focused ahead of the southeastward advancing cold front, on the southern periphery of the cyclonic mid-level flow and east of the dryline, across northeastern Oklahoma and northern Arkansas through 9-11 PM. This may include a few supercells accompanied by a risk for severe hail, locally strong surface gusts and potential for a tornado or two. ..Kerr.. 05/22/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 280 TORNADO IL MO 212255Z - 220500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 280 NWS Storm Prediction Center Norman OK 555 PM CDT Tue May 21 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of West central Illinois Eastern into south central Missouri * Effective this Tuesday afternoon from 555 PM until Midnight CDT. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Scattered damaging winds likely with isolated significant gusts to 75 mph possible Scattered large hail likely with isolated very large hail events to 2 inches in diameter possible SUMMARY...Scattered supercells and short line segments will remain possible through late evening in a broken band spreading eastward across Missouri toward west central Illinois. The more intense storms will be capable of producing a few tornadoes (one or two of which could be strong), large hail of 1-2 inches in diameter, and damaging gusts of 60-75 mph. The tornado watch area is approximately along and 60 statute miles east and west of a line from 50 miles north of Quincy IL to 25 miles west southwest of West Plains MO. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0883 CONCERNING TORNADO WATCH 281...282... FOR CENTRAL AND SOUTHERN WISCONSIN
Mesoscale Discussion 0883 NWS Storm Prediction Center Norman OK 0756 PM CDT Tue May 21 2024 Areas affected...Central and southern Wisconsin Concerning...Tornado Watch 281...282... Valid 220056Z - 220200Z The severe weather threat for Tornado Watch 281, 282 continues. SUMMARY...A developing squall line will quickly progress northeastward through the late evening hours. Damaging wind gusts up to 75 to 85 mph and embedded tornadoes will accompany it. DISCUSSION...Continued upscale growth has led to a north-south squall line developing across central WI. A few embedded mesovortices have been noted, along with a pair of embedded supercells on the southern flank near and north of Madison. The upstream low-level shear environment remains favorable for QLCS tornadoes where bowing segments can surge northward becoming more west to east oriented. In addition, deepening cold pools will continue to support severe damaging wind gusts. Marginally severe hail can't be ruled out, although waning instability and increasing MLCINH will likely keep the threat isolated. ..Barnes.. 05/22/2024 ...Please see www.spc.noaa.gov for graphic product...
