MD 0590 CONCERNING TORNADO WATCH 182... FOR PORTIONS OF WESTERN NORTH TEXAS INTO SOUTHWEST OKLAHOMA
Mesoscale Discussion 0590 NWS Storm Prediction Center Norman OK 0603 PM CDT Mon Apr 28 2025 Areas affected...Portions of western North Texas into southwest Oklahoma Concerning...Tornado Watch 182... Valid 282303Z - 290030Z The severe weather threat for Tornado Watch 182 continues. SUMMARY...Initial supercells will pose mainly a risk of very large hail and locally severe wind gusts. The tornado risk will increase into the evening as the low-level jet strengthens (00-01Z time frame). DISCUSSION...Initial discrete supercell has developed immediately south of the Red River in western North TX, where convergence is maximized near the dryline amid an uncapped air mass (per 21Z special NSSL sounding from Quanah, TX). Strong surface-based inability (3000 J/kg MLCAPE), driven by a warm/moist boundary layer beneath very steep midlevel lapse rates, will favor continued rapid updraft intensification. Around 50 kt of effective shear oriented oblique to the low-level convergence will support discrete/semi-discrete supercells. The initial hodograph (sampled by FDR VWP) depicts weak winds in the 1-2-km AGL layer, despite favorable deep-layer shear for supercells. This should initially favor some splitting supercells with a risk of very large hail. However, as the low-level jet rapidly increases, storms should intensify into dominant right-movers with an increasing supercell tornado risk. Current indications are that this evolution will occur in the 00-01Z time frame. The strong buoyancy, discrete/ semi-discrete mode, and increasing streamwise vorticity (around 400 m2/s2 effective SRH), will support a strong/intense tornado threat. ..Weinman.. 04/28/2025 ...Please see www.spc.noaa.gov for graphic product...

Valid 282306Z - 290030Z The severe weather threat for Tornado Watch 181 continues. SUMMARY...Organized severe thunderstorms will spread across southeast Minnesota into western/central Wisconsin later this evening. Tornado threat continues, but damaging winds may also become more common. DISCUSSION...Northeast-southwest band of thunderstorms, roughly 175 mi in length, has developed across southeast MN into northern IA. A few supercells are embedded along this corridor, but some propensity for an upward-evolving linear MCS may be under way. Latest radar trends suggest this developing MCS should track across much of southeast MN into western WI later this evening and a new tornado watch will likely be warranted downstream as this transpires. ..Darrow.. 04/28/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 180 TORNADO IA MN SD 281730Z - 290100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 180 NWS Storm Prediction Center Norman OK 1230 PM CDT Mon Apr 28 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northwest Iowa Southwest Minnesota Extreme Southeast South Dakota * Effective this Monday afternoon and evening from 1230 PM until 800 PM CDT. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Widespread large hail and scattered very large hail events to 3 inches in diameter likely Scattered damaging winds likely with isolated significant gusts to 80 mph possible SUMMARY...Isolated to scattered thunderstorms developing along a surface front will develop east/northeast through the afternoon. These storms will have the potential to produce large to very large hail, damaging wind gusts, and a few tornadoes. The tornado watch area is approximately along and 40 statute miles east and west of a line from 85 miles north of Redwood Falls MN to 30 miles west of Storm Lake IA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 3 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24035. ...Leitman Read more

Some consideration is being given to a severe thunderstorm watch. DISCUSSION...Synoptic front is surging southeast across southeast South Dakota early this evening. A pre-frontal confluence zone is contributing to a corridor of high-based cumulus from central NE into extreme northwest IA. Lightning is now being observed with frontal convection west-north of ONL, and this activity is expected to gradually intensify over the next few hours as it propagates downstream along a zone of modest instability. Strong deep-layer shear suggests some supercell potential, and hail will likely be the primary concern, though steep boundary-layer lapse rates do favor gusty winds. If this activity continues to increase in coverage/intensity a severe thunderstorm watch may be warranted. ..Darrow/Gleason.. 04/28/2025 ...Please see www.spc.noaa.gov for graphic product...
