Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1129 AM CDT Sun May 03 2026
Valid 031630Z - 041200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE MIDDLE MISSISSIPPI VALLEY
### SUMMARY
Isolated severe storms capable of hail and gusty winds are possible mainly this evening across northern/eastern Missouri into south-central Illinois.
Northern/eastern Missouri into south-central Illinois
Airmass modification and modest-caliber moist advection will occur north-northeastward into the region along and south of a decelerating southeastward-moving front. The limited low-level moisture, coupled with strong heating and mixing, should keep the airmass across the region capped through the afternoon. However, toward/after sunset, sufficient moistening atop the decoupling boundary layer should support increasing thunderstorm development this evening. Convection will tend to be rooted around 750-850 mb, and while elevated buoyancy will not be robust, the steep lapse rates could yield some severe hail (and possibly gusty winds) in the presence of 40+ kt shear through the cloud-bearing layer.
Far South Florida
While a couple of strong storms could occur through the afternoon, cloud cover and an increasingly prevalent post-frontal regime, along with weak lapse rates in the cloud-bearing layer, should tend to limit storm intensity inland.
Northern California/southwest Oregon
Thunderstorms are expected along the northern periphery of the upper low off the central California coast. Increasing mid-level moisture and cold mid-level temperatures will support modest buoyancy amid moderate easterly flow aloft, supporting the potential for small hail and gusty winds with these westward progressing storms during the late afternoon and early evening. However, organized severe storm potential is expected to remain low.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1203 AM CDT Sun May 03 2026
Valid 041200Z - 051200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE MIDWEST
### SUMMARY
Strong to severe thunderstorms are possible across portions of the Midwest late Monday afternoon into Monday night.
Synopsis
An upper trough will dig southward across the northern Plains/Upper Midwest on Monday. At the same time, a upper low near CA and attendant trough will pivot eastward toward the Southwest. At the surface, low pressure over Ontario will develop northeast toward James Bay while a trailing cold front moves southeast across the northern/central Plains and the Upper Midwest/Great Lakes vicinity. Meanwhile, a second surface low is forecast to deepen in the vicinity of western KS/OK with a dryline extending southward across central KS/western OK and west-central TX. Modest southerly return flow will transport mainly 50s to near 60 F dewpoints northward across OK/eastern KS into MO. More modest boundary layer moisture is expected ahead of the cold front across portions of the Midwest.
Eastern KS toward Lake Michigan and western OH
Modest boundary layer moisture and uncertainty in timing/location of the surface front contribute to uncertainty in severe potential for Monday. Nevertheless, cool temperatures aloft will support steep midlevel lapse rates and a corridor of 1000-1500 J/kg MLCAPE appears likely ahead of the front. A lead shortwave impulse will migrate across the OH Valley during the day. This may provide sufficient forcing for ascent for isolated thunderstorm development within an uncapped and modestly sheared airmass. Strong storms could produce small hail and gusty winds. Additional strong storms are possible during the afternoon further to the northwest near the surface front from eastern IA toward Lake Michigan. However, boundary layer moisture will likely be even more limited across this area, leading to weaker instability. Nevertheless, a well mixed boundary layer could support strong wind gusts.
Stronger ascent will arrive after 00z across the central Plains and Mid-MS Valley vicinity in tandem with an increasing southwesterly low-level jet. Thunderstorms are expected to develop near the triple points in central/eastern KS and into MO as the surface cold front drops southward. This activity may pose a risk for hail and strong gusts.
Southwest OK vicinity
Some forecast guidance develops thunderstorms near the dryline late afternoon/early evening across the southwest OK vicinity. Large scale ascent will remain nebulous across the region and capping may preclude thunderstorm development. However, strong heating west of the dryline and strong convergence in model guidance are noted. If a storm could break the cap, a severe risk could develop. However, coverage/temporal risk would likely be limited and confidence in this scenario is low, precluding severe probabilities at this time.

Valid 051200Z - 061200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF EASTERN OKLAHOMA…NORTHEAST TEXAS…AND ARKANSAS
CORRECTED FOR SUMMARY
SUMMARY
Isolated to scattered strong to severe storms are possible Tuesday afternoon and evening across portions of eastern Oklahoma and northeast Texas into the Mid-South.
Synopsis
Deep-layer southwesterly flow will increase across the southern Plains to the Ohio Valley and Northeast as the upper trough over the Upper Midwest and northern/central Plains and an upper trough over the Southwest begin to phase. At the surface, a cold front is forecast to extend from southern Lower MI to northern OK Tuesday morning. This boundary will develop slowly southeast through the period, becoming oriented from NY to the Mid-South to north-central TX by Wednesday morning. During the afternoon, a dryline will be oriented across central TX. Ahead of the surface front and east of the dryline, increasing southerly low-level flow will transport 60s F dewpoints across the Sabine Valley into AR. The surface front and dryline will serve as a focus for strong to severe thunderstorm development during the afternoon/evening.
OK/TX to the Mid-South
Convective development is likely near the surface triple point and cold front by 00z as forcing for ascent impinges on the moist and moderately unstable airmass in the eastern OK/AR vicinity. Thunderstorm coverage will likely increase through the evening as a modest low-level jet develops. Any discrete convection that develops will pose a risk for large hail and perhaps a tornado or two. However, convection may become linear along the surface front rather quickly, with an accompanying increase in damaging wind potential.
Severe potential along the dryline across parts of OK/TX is more uncertain/conditional. Capping and nebulous large-scale ascent (especially with southwest extent across TX) may suppress convection. However, if a storm can develop within the favorable thermodynamic and kinematic parameter space, large hail will be possible.

Note on Medium Range Outlooks
You are looking at an outlook that is part of the medium range forecast (the outlook for days 4-8). The most important thing to note is that lack of a risk does not mean zero risk. Generally speaking, confidence has to be pretty high for the Storm Prediction Center to have an outlook area this far into the future.
When no specific risk areas are shown, you might see one of these phrases:
- Predictability Too Low: This means that severe storms might be possible, but forecasters aren't confident enough about where or when they might occur. Think of it as the models showing different possibilities, like pieces of a puzzle that haven't come together yet.
- Potential Too Low: This means forecasters are fairly confident that widespread severe weather is NOT expected on that day. While isolated storms might still occur, the chance of reaching severe criteria across any given area is very low.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0250 AM CDT Sun May 03 2026
Valid 061200Z - 111200Z
DISCUSSION
Day 4/Wed – East TX to the Lower MS and TN Valley vicinity
Strong southwesterly deep-layer flow will overspread the region ahead of an upper trough pivoting east across the Plains toward the Mid-MS Valley. At the surface, a cold front will be oriented from the OH Valley to southern AR and central TX. Ahead of the front, rich Gulf moisture will be in place across southern and eastern TX into the Lower MS Valley eastward toward AL. Moderate to strong destabilization is expected across the warm sector ahead of the southward-sagging cold front. Supercell wind profiles are evident in forecast soundings. However, given linear forcing along the front and deep-layer flow largely parallel to the boundary, it is uncertain if discrete storms will be possible. Nevertheless, severe potential is still expected with clusters and linear segments given the favorable thermodynamic environment and strong vertical shear.
Day 5/Thu - South TX and parts of the Southeast
Some severe potential could persist into Thursday across south TX as the cold front continues to develop southward across a very moist and unstable airmass. However, large-scale ascent may be limited as forcing associated with the eastern U.S. upper trough focuses well northeast of the region. Shortwave upper ridging also may overspread region ahead of an upper low/trough over northwest Mexico.
Additional strong or severe storms will be possible across parts of the Southeast toward the Carolinas and Mid-Atlantic as the cold front shifts east across that region. However, widespread showers/thunderstorms and cloud cover may limit destabilization, and convection could become anafrontal by this time.
Days 6-8/Fri-Sun
Spread beings to increase across model guidance by the weekend, though mean upper troughing across the East seems likely to persist. This typically would not be ideal for severe potential. However, an upper shortwave trough is forecast to move across the southern Rockies into the southern Plains. Forecast guidance varies widely with the timing and evolution of these features however, and predictability is low.
