MD 2116 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR FAR SOUTHEAST MINNESOTA INTO WEST-CENTRAL/SOUTHWESTERN WISCONSIN AND FAR NORTHERN IOWA
Mesoscale Discussion 2116 NWS Storm Prediction Center Norman OK 0243 PM CDT Mon Sep 22 2025 Areas affected...Far southeast Minnesota into west-central/southwestern Wisconsin and far northern Iowa Concerning...Severe potential...Watch unlikely Valid 221943Z - 222115Z Probability of Watch Issuance...20 percent SUMMARY...Isolated large hail and perhaps a tornado could occur near an outflow boundary in west-central Wisconsin and vicinity. A watch is not anticipated. DISCUSSION...On the southern flank of a positively tilted trough in the upper Great Lakes region, a severe storm has developed south of La Crosse, WI. This storm has formed along the edge of outflow from earlier convection. Strong heating to the southwest of this activity has promoted around 1500 J/kg MLCAPE in the vicinity of the Mississippi River. While storm coverage may remain isolated, 35 kts of 0-6 km shear (per KARX VAD) suggests supercells are possible. Mid-level lapse rates are modest, but cold air aloft would support large hail, especially with supercells. The KARX VAD also shows enlarged low-level hodographs (though low-level shear is larger in the cooler air). There will be at least a brief window for greater tornado potential along the outflow boundary before 850 mb veer later this afternoon. ..Wendt/Smith.. 09/22/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 2 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 0251 PM CDT Mon Sep 22 2025 Valid 231200Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS EASTERN OKLAHOMA...MUCH OF ARKANSAS...AND FAR NORTHEAST TEXAS... CORRECTED FOR HEADLINE ...SUMMARY... Severe storms are possible from the southern Plains to the Tennessee Valley on Tuesday. The strongest thunderstorm activity is expected across eastern Oklahoma into northeastern Texas and Arkansas, where supercells capable of all severe hazards are possible by afternoon. ...Eastern Oklahoma into Arkansas and northeast Texas... A positively tilted large-scale trough will move slowly south-southeastward across the central Rockies and adjacent Plains through the period. Downstream of the trough, a convectively augmented midlevel impulse and accompanying 50 kt jet will track eastward across KS and northern OK during the day. A related MCS will be advancing eastward across eastern KS, northern OK, and southwest MO on Tuesday morning -- at the nose of a 40 kt low-level jet. Instances of severe wind and hail will be possible with this activity, especially along its southern flank where buoyancy will be maximized. In the wake of these storms, a weak surface low will track eastward across northern OK, while a southward-extending cold front moves slowly eastward from central into eastern OK. Despite early-day convective overturning across parts of eastern OK, diurnal heating amid lower 70s dewpoints should erode inhibition and support widely scattered thunderstorms both along/immediately ahead of the front and along residual outflow boundaries. Strong surface-based buoyancy and around 40 kt of effective shear oriented oblique to the front should initially favor a few semi-discrete supercells from eastern OK into AR. These storms will pose a risk of large hail, severe wind gusts, and perhaps a couple tornadoes -- given clockwise curved low-level hodographs (upwards of 200 m2/s2 effective SRH). Storms should gradually grow upscale as they move southeastward into the evening/overnight hours. Higher wind/tornado probabilities were considered over eastern OK into AR given the favorable environment, though continued uncertainty regarding early-day convection and implications on storm mode limit forecast confidence at this time. ...Central Texas... Moderate instability is forecast across central/northern Texas Tuesday afternoon with eroding inhibition by mid-afternoon. Shear will be relatively weak, but will increase during the afternoon/evening as a mid-level jet streak drifts south. The most favorable zone for thunderstorm development will be the triple point where the cold front intersects a dryline across North Texas. However, additional isolated storms may also develop along the dryline and cold front. Isolated large hail and damaging wind gusts will be the primary threat from these storms Tuesday afternoon/evening. ...Mid-Atlantic... Downstream of a broad midlevel trough, widely scattered thunderstorms will be evolving in a moist/moderately unstable air mass during the afternoon. Around 20-30 kt of deep-layer shear may promote a couple loosely organized clusters with a risk of locally damaging gusts. ..Weinman.. 09/22/2025 Read more

Downstream of the trough, a convectively augmented midlevel impulse and accompanying 50 kt jet will track eastward across KS and northern OK during the day. A related MCS will be advancing eastward across eastern KS, northern OK, and southwest MO on Tuesday morning -- at the nose of a 40 kt low-level jet. Instances of severe wind and hail will be possible with this activity, especially along its southern flank where buoyancy will be maximized. In the wake of these storms, a weak surface low will track eastward across northern OK, while a southward-extending cold front moves slowly eastward from central into eastern OK. Despite early-day convective overturning across parts of eastern OK, diurnal heating amid lower 70s dewpoints should erode inhibition and support widely scattered thunderstorms both along/immediately ahead of the front and along residual outflow boundaries. Strong surface-based buoyancy and around 40 kt of effective shear oriented oblique to the front should initially favor a few semi-discrete supercells from eastern OK into AR. These storms will pose a risk of large hail, severe wind gusts, and perhaps a couple tornadoes -- given clockwise curved low-level hodographs (upwards of 200 m2/s2 effective SRH). Storms should gradually grow upscale as they move southeastward into the evening/overnight hours. Higher wind/tornado probabilities were considered over eastern OK into AR given the favorable environment, though continued uncertainty regarding early-day convection and implications on storm mode limit forecast confidence at this time. ...Central Texas... Moderate instability is forecast across central/northern Texas Tuesday afternoon with eroding inhibition by mid-afternoon. Shear will be relatively weak, but will increase during the afternoon/evening as a mid-level jet streak drifts south. The most favorable zone for thunderstorm development will be the triple point where the cold front intersects a dryline across North Texas. However, additional isolated storms may also develop along the dryline and cold front. Isolated large hail and damaging wind gusts will be the primary threat from these storms Tuesday afternoon/evening. ...Mid-Atlantic... Downstream of a broad midlevel trough, widely scattered thunderstorms will be evolving in a moist/moderately unstable air mass during the afternoon. Around 20-30 kt of deep-layer shear may promote a couple loosely organized clusters with a risk of locally damaging gusts. ..Weinman.. 09/22/2025 Read more

MD 2115 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR SOUTHEAST INDIANA AND NORTHERN KENTUCKY INTO CENTRAL OHIO
Mesoscale Discussion 2115 NWS Storm Prediction Center Norman OK 1228 PM CDT Mon Sep 22 2025 Areas affected...southeast Indiana and northern Kentucky into central Ohio Concerning...Severe potential...Watch possible Valid 221728Z - 222030Z Probability of Watch Issuance...40 percent SUMMARY...Corridors of strong to damaging gusts may develop after 20Z from southeast Indiana and northern Kentucky into central Ohio. DISCUSSION...An area of rain and thunderstorms associated with a midlevel disturbance is currently moving across southern Indiana. Ahead of this feature, scattered showers are evident in association with low-level warm advection over southern Ohio and northeast Kentucky. Heating and destabilization is most prominent south of these features into Kentucky, where visible satellite imagery shows areas of clearing. Precipitable water values are over 1.50", with MLCAPE currently in the 500-1000 J/kg range. As the midlevel wave translates northeast across Indiana and into Ohio, boundary layer mixing with gusty southwest winds during the peak heating hours will lead to strengthening storms, possibly linear in nature. Mean wind speeds of 30-40 kt in the low to mid levels and ample downdraft mass will result in strong wind gusts, perhaps damaging in spots. Any such line of storms tied to the vorticity max could exhibit periods of weak low-level rotation as well, perhaps resulting in localized severe gusts. ..Jewell/Smith.. 09/22/2025 ...Please see www.spc.noaa.gov for graphic product...
