THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST OKLAHOMA AND ARKLATEX

### SUMMARY

Scattered severe thunderstorms are expected today from parts of the southern Plains into the ArkLaTex and lower Mississippi Valley. Large hail, damaging winds, and a few tornadoes will be possible. The greatest threat for supercells with very large hail (2+ inches) should focus across parts of southeast Oklahoma to the ArkLaTex region.

Oklahoma/North Texas to ArkLaTex/Lower Mississippi Valley

A persistent band of non-severe thunderstorms this morning, and its related outflow, continue to settle southward across southeast Oklahoma, south-central/southeast Arkansas into northwest Mississippi. The southeastern-most portion of the convective line may re-intensify across the ArkLaMiss today as the boundary layer warms, with some potential for a secondary round of upscale-growing storms into tonight across generally the same ArkLaMiss/Lower Mississippi Valley region. This includes damaging winds and some tornado potential, primarily QLCS-related, especially into this evening/tonight via a somewhat stronger wind field.

The western periphery of the ongoing complex and its outflow should continue to decelerate, stall, and modify through the afternoon, setting the stage for a semi-corridor of heightened severe potential via this modifying outflow in conjunction with the surface triple point to this west, with intensifying storm development anticipated toward the 4pm-6pm/21z-23z time frame across southeast Oklahoma and nearby ArkLaTex. This will be in the presence of ample buoyancy and steep mid-level lapse rates. Wind profiles will further support intense supercells capable of large to very large hail, along with a tornado risk, accentuated by backed low-level winds near the outflow boundary and east of the triple point. With time, some clustering may occur with an increased damaging wind threat as convection spreads east-southeastward.

Additionally, locally intense storms may also focus farther west across southern Oklahoma/Red River vicinity along/north of the southward-sagging front where relatively rich low-level moisture will persist in the presence of strong deep-layer shear.

Texas Dryline - North/Central TX to Hill Country/Rio Grande

A highly conditional scenario exists in vicinity of the south/southwestward-extending dryline late this afternoon/early evening, with a concerning (mostly hail) severe potential should storms develop. Short-term guidance varies on the aggressiveness of eastward-mixing/dryline through peak heating, although the 12z Fort Worth sounding sampled respectable warm-sector moisture content this morning (upper quartile climo; 14.4 g/kg mean mixing ratio). Regardless, a concerning high degree of instability (3000+ J/kg MLCAPE) will exist near/east of the dryline late this afternoon.

Short-term models remain rather sparse on explicit indications of near-dryline convective initiation. However, sufficient dry line convergence and post-dryline heating/mixing could plausibly lead to isolated but intense thunderstorm development in the presence of negligible capping/boundary-layer inhibition. And while mid-level capping will be more prevalent, especially with southward extent, upstream 12z soundings from Midland/El Paso (both around -14C 500mb) suggest that some additional mid-level cooling is probable. Notably stronger mid/high-level winds were also observed in these RAOBs with 50+ kt winds and 100+ kt winds at 500mb/250mb, respectively.

Several sub-regional zones of potential isolated deep convective development are at least plausible, including in closer proximity to the surface triple point across North Texas/Metroplex general vicinity, extending into parts of central Texas where low-level mixing may be less impactful, and lastly in the immediate vicinity of the Rio Grande, potentially influenced by possible storm development across the border. If/where storms do develop late this afternoon/early evening, very large hail could occur along with localized severe-caliber wind gusts.

Great Lakes/Ohio Valley

A weak/convectively influenced mid-level shortwave trough will move northeastward across the Midwest and Upper Great Lakes today. Convection ahead of a cold front has generally weakened this morning across the mid Mississippi Valley, but multi-layer cloud cover remains prevalent. Modest-caliber low-level moisture will continue to advect north-northeastward through the day ahead of the front, supporting weak instability with filtered daytime heating. Loosely organized clusters/cells that develop/intensify this afternoon may pose an isolated threat for damaging winds as they move northeastward this afternoon and evening. The residual clouds and a weakening low-level wind field should curb the overall magnitude of the severe risk, hence maintenance of MRGL/Category 1 risk.

Western Nebraska

A couple of stronger storms may develop late this afternoon/early evening near a southeastward-moving front, further influenced by a mid-level impulse embedded within the base of the large-scale trough centered over the Canadian Prairies. In the presence of a strong deep-layer wind field, modest-caliber CAPE atop a well-mixed boundary layer could potentially yield an isolated severe gust/hail.

Outlook for Saturday, April 25

Outlook Summary

Severe thunderstorms, with a risk for large to very large hail, damaging wind gusts, and a few tornadoes, are possible across parts of the southeastern Great Plains into the ArkLaTex, primarily Saturday afternoon and evening.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Fri Apr 24 2026

Valid 251200Z - 261200Z

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM NORTH-CENTRAL INTO EASTERN OKLAHOMA AND ADJACENT PARTS OF SOUTHEAST KANSAS AND WESTERN ARKANSAS

### SUMMARY

Severe thunderstorms, with a risk for large to very large hail, damaging wind gusts, and a few tornadoes, are possible across parts of the southeastern Great Plains into the ArkLaTex, primarily Saturday afternoon and evening.

Synopsis

A deep mid/upper-level low is forecast to remain nearly stationary over the Canadian Prairie region on Saturday. This low will continue to anchor a large-scale mid/upper trough covering much of the western and central CONUS through the period. A shortwave trough initially off of the southern CA coast will move east-northeastward toward the Southwest by Sunday morning. Downstream of this system, a low-amplitude midlevel shortwave trough may emerge from the southern Rockies and begin to impinge upon a moist and unstable environment across the south-central Plains by afternoon.

At the surface, a surface low is forecast to gradually deepen across the TX Panhandle region through the day, with a dryline extending southward from this low into parts of west-central and southwest TX. An outflow-influenced surface boundary will initially extend east-southeast of the low into parts of the Southeast. This boundary is forecast to move northward as a warm front through the day across parts of OK/north TX into the ArkLaTex region.

Southern/central Plains into the ArkLaTex

Relatively steep lapse rates atop a richly moist boundary layer will result in moderate to strong destabilization along/east of the dryline and near/south of the effective warm front. Details of diurnal storm development and coverage remain unclear, but at least isolated storm development will be possible near or just to the cool side of the effective warm front by late afternoon, as the approaching low-amplitude midlevel shortwave trough glances the stronger instability. Initial storms across eastern KS/OK may be somewhat elevated, but surface-based convection may eventually develop near the warm front/dryline intersection and expand in coverage into the evening.

Initial supercell development will pose a threat of large to very large hail and localized damaging gusts. Low-level flow/shear will generally remain modest, but large instability and enhanced SRH near the surface boundary could result in a localized region of greater tornado potential. With time, some upscale growth may result in an organized storm cluster moving southeastward to the ArkLaTex and potentially the lower MS Valley along the primary instability gradient. This evolution could be accompanied by increasing damaging-wind potential, though embedded supercells may continue to pose a localized hail and tornado threat well into the evening.

Development along the dryline across TX continues to be uncertain, since this area will be removed from stronger large-scale ascent. However, strong heating and removal of CINH could result in isolated supercell development, with an attendant threat of large to very large hail, and a nonzero tornado and wind risk.

Farther north, a separate area of storm development is possible from central/northern KS into southeast NE. While instability and deep-layer flow/shear will generally be weaker with northward extent, cool temperatures aloft and modest midlevel flow could support a threat for isolated hail and strong/damaging gusts with the strongest storms during the afternoon and early evening.

Parts of the Southeast into the Carolinas/Virginia

A broad area of weak to moderate instability may develop during the afternoon from parts of the Southeast into the Carolinas/Virginia, near and to the warm side of a weak surface front. Wind profiles will be relatively modest, but may support marginally organized storms. Guidance continues to vary regarding placement of the primary surface boundary and potential for any MCV development from late D1/Friday. Low severe probabilities may eventually need to expanded across parts of the Southeast, once details become better resolved.

Outlook for Sunday, April 26

Outlook Summary

Widely scattered severe storms with potential to produce large hail and a couple of strong tornadoes are possible by early Sunday evening across parts of the central and southern Great Plains, before one or two organizing clusters of storms spread toward the middle/lower Missouri Valley with potentially damaging wind gusts.

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS SUNDAY EVENING INTO SUNDAY NIGHT ACROSS MUCH OF KANSAS AND ADJACENT PORTIONS OF NORTHERN OKLAHOMA…WESTERN MISSOURI

### SUMMARY

Widely scattered severe storms with potential to produce large hail and a couple of strong tornadoes are possible by early Sunday evening across parts of the central and southern Great Plains, before one or two organizing clusters of storms spread toward the middle/lower Missouri Valley with potentially damaging wind gusts.

Discussion

A remnant elongated cyclonic mid-level circulation/shear axis may tend to shift north-northeastward through Saskatchewan/Manitoba through this period, while larger-scale troughing along an axis inland of the U.S. Pacific coast through the Hudson Bay vicinity weakens through this period. However, mid/upper ridging across southern/central Mexico into portions of the southern Great Plains and lower Mississippi Valley appears likely to maintain considerable strength, while a notable short wave perturbation accelerates out of the southern Great Basin/lower Colorado Valley, within strong southwesterly flow between the two features.

Models suggest that stronger mid-level height falls will generally overspread the eastern Colorado/western Kansas/southwest Nebraska vicinity of the high plains late Sunday afternoon into evening, before reaching southern portions of the middle Missouri Valley by 12Z Monday, accompanied by a developing low within the northern portion of deepening surface troughing extending southward into the southern Great Plains. Another low, developing by Sunday afternoon across the southeastern Colorado/Texas and Oklahoma Panhandle region may reach portions of central Kansas.

In response to these developments, seasonably moist low-level air, initially confined to the southern Great Plains, perhaps as far north as central Oklahoma at the outset of the period, may tend to advect in a corridor ahead of a sharpening dryline across western Oklahoma into western Kansas by late afternoon. Downstream, models suggest that a warm frontal zone may become better defined by early Sunday evening across southern Kansas into the Ozark Plateau vicinity, before tending to shift northward.

Great Plains… Although though there is not a strong signal yet evident within latest model output concerning potential convective evolution during this period, at least isolated to perhaps widely scattered supercell development may initiate along the dryline as far south as northwest Texas by late Sunday afternoon, in the presence of destabilization and strengthening shear. By early Sunday evening, this probably will include enlarging, clockwise curved low-level hodographs beneath a strengthening southerly low-level jet. This may become supportive of increasing potential for a couple of strong tornadoes, in addition to large hail, with increasing storm coverage probable across the western Kansas vicinity.

Gradually, large-scale forcing for ascent, focusing along the warm front, may support one or two upscale growing clusters of storms spreading into the middle/lower Missouri Valley overnight, with damaging wind gusts becoming the more prominent severe hazard along with perhaps some continuing risk for tornadoes.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0401 AM CDT Fri Apr 24 2026

Valid 271200Z - 021200Z

DISCUSSION

Latest medium-range model output suggests that a significant short wave perturbation emerging from the Southwest will pivot northeast of the middle/lower Missouri Valley, into the upper Great Lakes region, Monday through Monday night. It appears that the warm sector of an associated sub-1000 mb surface cyclone will become characterized by at least moderately large CAPE, ahead of the dryline/cold front overspreading much of the middle Mississippi Valley during the afternoon into evening. In the presence of strong deep-layer shear, organized severe thunderstorm activity appears probable. It remains a bit unclear the extent to which sustained supercell development will be maintained, as opposed to convection quickly growing upscale into one or more clusters/lines, but there appears at least some potential for a few strong tornadoes, in addition to large hail and potentially widespread strong to severe wind gusts.

In the wake of this activity, into the middle to latter portion of next week, convective potential becomes more unclear as strong flow trends westerly, and broadly confluent across and east of the Rockies, between broad mid-level troughing overspreading the northern tier and broad mid-level ridging across the southern tier. Another, initially notable, short wave perturbation emerging from the southern mid-latitude/subtropical eastern Pacific is still forecast to progress into the Southwest. But latest model output suggests that it may become sheared while continuing across and east of the southern Rockies, with only modest to weak surface cyclogenesis currently forecast along a remnant frontal zone across the southern Great Plains through Southeast.
