THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS WESTERN KANSAS

### SUMMARY

Widely scattered severe storms capable of severe wind gusts and large hail are possible over portions of the central and southern High Plains this afternoon and evening. More isolated occurrences of damaging wind are possible from the middle Texas coast into Deep South Texas, the eastern Carolinas, and parts of the Columbia Basin into the northern Intermountain region.

Central/southern High Plains including western Kansas

Strong boundary-layer heating is forecast in the vicinity of a High Plains surface front and dryline this afternoon with temperatures reaching the mid 90s to around 105 F. The hot temperatures will combine with dewpoints in the mid 50s to mid 60s and modestly steep mid-level lapse rates to yield a narrow axis of moderate instability with MLCAPE of 1500-2500 J/kg across western Kansas southward into western Oklahoma and the eastern Texas Panhandle. Forcing for ascent preceding a shortwave trough is expected to contribute to isolated to widely scattered thunderstorms by mid-afternoon from the vicinity of the thermal low in southeast Colorado to along the front and dryline from northeast Colorado into the Oklahoma/Texas Panhandles.

Forecast soundings along the front feature a vertically veering wind profile with 30-35 kt of deep-layer shear, which will be sufficient for at least episodic supercell structures with a risk for large hail. In contrast, the storms forming in the hot, deeply mixed air mass west of the boundary are more likely to produce sporadic severe wind gusts. A corridor of more concentrated severe wind gusts may materialize across portions of southwest Kansas by evening, particularly if organized cold pool development occurs with an evening time low-level jet increase.

Middle Texas Coast to Deep South Texas

As Bertha continues westward over the northwest Gulf, a belt of enhanced mid-level flow will precede Bertha and spread atop a hot and moist boundary layer inland, with moderate instability developing by afternoon along the middle Texas coast. Similar to Wednesday, widely scattered thunderstorms are expected during the afternoon within an environment characterized by 30-40 kt of deep-layer shear, steep low-level lapse rates, and high PW content. As such, the potential will exist for locally damaging downburst winds as storms spread west-southwestward along the coast into Deep South Texas during the afternoon and evening.

Columbia Basin/northern Intermountain West

Weak height falls are expected while mid/upper-level winds strengthen regionally ahead of an upper low off the coast of the Pacific Northwest. Daytime heating along favored terrain, in conjunction with the glancing influence of the passing disturbance, will aid in isolated to widely scattered thunderstorms by mid-afternoon within a moderately unstable and steep lapse rate environment. The strengthening upper-level winds will enhance vertical shear, supporting the potential for some storm organization with an associated risk for locally damaging wind gusts and marginally severe hail.

Eastern Carolinas

A very moist air mass and cloud breaks to the south of front-associated convection early today across North Carolina should allow for at least moderate destabilization across parts of the coastal plain. This may result in a corridor of more concentrated thunderstorm development, near the intersection of the outflow from the morning storms with the sea-breeze boundary. Modest deep-layer shear will coincide with steepening low-level lapse rates and high PW content to yield locally intense wet microbursts capable of damaging winds this afternoon until around sunset.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF NORTH DAKOTA INTO NORTHWEST MINNESOTA

### SUMMARY

Isolated severe thunderstorms are possible on Friday across portions of the Dakotas into northern Minnesota.

Dakotas into northern MN

Strengthening northwesterly flow aloft will overspread the region Friday afternoon into early Saturday in response to a shortwave upper trough moving across Manitoba/western Ontario and the northern Great Lakes. At the surface, a front will develop south/southeast across parts of north Dakota and northern MN.

South/southwesterly low-level flow ahead of the front will transport modest boundary layer moisture northward across parts of ND/SD and northern/central MN. This will occur on the eastern periphery of a strong upper ridge building over the Rockies/High Plains. As a result of upper ridging, warm temperatures in the 850-700 mb layer may result in at least weak capping over portions of the region. Nevertheless, a plume of steep midlevel lapse rates will support moderate destabilization (1000-2000 J/kg MLCAPE).

Vertically veering wind profiles, also increasing in speed with height, will result in supercell wind profiles. Forecast soundings show a well-mixed boundary layer, with steep 0-3 km lapse rates. Organized cells are expected to develop by late afternoon near the surface boundary and spread east/southeast with time through the evening. A low-level jet is also forecast to increase during the evening/nighttime hours. The main risk with these storms will be from large hail and strong to severe wind gusts. If storms can become surface-based, a tornado or two also could occur. The strengthening low-level jet could maintain elevated convection into the nighttime hours across northern MN, but instability weakens an inhibition increases with south and east extent across the Upper MS Valley. This should keep severe potential relatively confined within a narrow corridor across portions of the Dakotas into northern MN.

SC vicinity

Isolated to scattered thunderstorms are expected Friday afternoon within a moderately unstable and very moist airmass. Vertically veering flow, increasing to around 20-30 kt around 1-3 km will provide around 25 kt effective shear as a surface boundary sags south and east across the region. This may be sufficient for a couple of organized clusters capable of producing sporadic wind damage.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0130 AM CDT Thu Jul 23 2026

Valid 251200Z - 261200Z

NO SEVERE THUNDERSTORM AREAS FORECAST

### SUMMARY

Severe thunderstorm potential appears limited on Saturday.

Northern High Plains to Upper Midwest

An amplified upper ridge will remain centered over the High Plains on Saturday. Moderately enhanced west to northwesterly flow aloft will overspread portions of the region near the crest of the ridge and into the Upper MS Valley. Forecast guidance depicts one or more shortwave impulses rounding the ridge from eastern MT into the Dakotas, and possibly parts of the Upper Midwest. Forecast soundings indicate capping across the Upper Midwest, which may limit thunderstorm potential despite a moistening boundary layer with time.

Further west across eastern MT into the western Dakotas, low-level moisture will be limited. However, steep midlevel lapse rates will result in weak destabilization as strong heating occurs during the day. Deep boundary layer mixing is forecast, and isolated to scattered high-based convection could develop within the weakly unstable airmass. Some potential for strong gusts will accompany this activity, but it is unclear if sufficient instability and moisture will exist to support severe wind gusts.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0226 AM CDT Thu Jul 23 2026

Valid 261200Z - 311200Z

DISCUSSION

Days 4-5/Sun-Mon – Upper Midwest toward the Ohio Valley

Enhanced northwesterly flow aloft will overspread the Upper Midwest to the Ohio Valley on Sunday and Monday as several shortwave impulses migrate through the area on the eastern periphery of a strong upper ridge over the Plains. A seasonally very moist airmass will reside across much of these areas, supporting strong destabilization each day. On Sunday, a corridor of severe thunderstorm potential appears possible across parts of MN/WI toward northern IA/IL as a weak shortwave impulse initially over the Dakotas spreads east. While details regarding storm coverage remain uncertain, sufficient deep layer shear and strong instability will be in place, and at least isolated storm clusters could pose a risk for damaging winds.

By Monday, an upper shortwave trough will emanating from an upper low near Hudson Bay will dig southward across the Great Lakes. This will result in increasing northwesterly flow aloft. Meanwhile, a surface low may move eastward across the Great Lakes near the international border while a stronger nocturnal low-level jet develops over parts of the Great Lakes and Ohio Valley. This stronger flow will overspread a moist and unstable airmass, and potential for thunderstorm clusters developing into an MCS appears possible.

While details remain uncertain regarding convective evolution and coverage on Sunday and Monday, through broader synoptic pattern appears favorable for at least isolated severe thunderstorms. The 15 percent severe areas may shift some in the coming days as details become more clear.

Days 6-8/Tue-Thu

It is possible some severe potential could shift east/southeast on Tuesday toward the central Appalachians and the Mid-Atlantic. Deep-layer northwesterly flow will not be as strong as prior days, but could still be sufficient for some organized severe risk. Confidence in where greater risk corridors may develop is low, and will largely be influenced by convective evolution in the Days 4-5/Sunday-Monday periods.

A strong upper ridge will shift west across the western U.S. late in the period, bringing a broad area of generally weak deep-layer northwesterly flow to the eastern half of the CONUS. Some thunderstorm potential is likely within this typical summertime pattern across the Plain into the East, but severe potential is uncertain.
