Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0748 PM CDT Mon Sep 28 2026
Valid 290100Z - 291200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE WESTERN/CENTRAL DAKOTAS AND CENTRAL HIGH PLAINS
### SUMMARY
Isolated strong to locally severe storms remain possible this evening across parts of the western/central Dakotas and also the central High Plains.
Parts of the Dakotas into the central High Plains
Widely scattered strong thunderstorms are ongoing this evening from eastern ND into western SD. While low/midlevel lapse rates are generally weak, relatively rich low-level moisture is supporting MLCAPE of near/above 1000 J/kg, with 25-35 kt of effective shear sufficient for occasional storm organization. Isolated hail and strong to severe gusts cannot be ruled out this evening, though a weakening trend is expected later tonight as convection becomes increasingly elevated with time.
Farther south, isolated strong storms are ongoing this evening across parts of northwest NE, and also near the CO/KS border. Occasional supercell structures will be possible through dusk, though modest lapse rates and buoyancy may tend to limit the magnitude of the severe threat. See MCD 2332 for more information regarding the short-term threat in this area.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1215 PM CDT Mon Sep 28 2026
Valid 291200Z - 301200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS TUESDAY AFTERNOON INTO EARLY WEDNESDAY FROM SOUTHERN AND EASTERN NEW MEXICO INTO WEST TEXAS
### SUMMARY
Isolated severe thunderstorm gusts and a couple of tornadoes will be possible Tuesday afternoon through early Wednesday from southeast New Mexico into west Texas.
Southeast NM/west TX Tuesday afternoon into early Wednesday
A midlevel low will move eastward over AZ/NM while the remnants of Hurricane Polo eject northeastward toward far west TX and southeast NM. An influx of midlevel moisture with the tropical system from the Pacific and low-level moisture from TX into NM will support increasing convection Tuesday afternoon into the overnight hours across NM and west TX. Lapse rates aloft will remain poor with the approach of the remnant tropical/warm core low, but moist profiles and substantial vertical shear with curved hodographs suggest the potential for at least isolated wind damage and possibly a couple of tornadoes with embedded supercells. The severe threat is expected to begin Tuesday afternoon across far west TX and southern NM and continue into Tuesday night/Wednesday morning across the southern High Plains.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0225 PM CDT Mon Sep 28 2026
Valid 301200Z - 011200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM NORTHWEST TEXAS INTO WESTERN OKLAHOMA
### SUMMARY
A few damaging gusts and a couple of tornadoes will be possible across parts of the southern Great Plains.
Southern Plains
A midlevel closed low will move slowly eastward from NM to west TX with slow weakening by late Wednesday, while the prior remnants of Hurricane Polo will have ejected northeastward over the southern High Plains and dissipated by Wednesday morning. An associated lee cyclone will be maintained through the day, but also begin to fill by Wednesday night. This all suggests a slow downtrend in the mass response and associated wind profiles. Midlevel lapse rates will also remain modest given prior days clouds/rainfall muting surface heating across the southern Rockies.
In the wake of morning clouds/convection, there is the potential for a narrow zone of surface heating and destabilization along and east of the lee trough which could support additional thunderstorm development during the afternoon/evening. Will maintain 5-15% severe probabilities though the overall synoptic evolution casts some doubt on both the coverage and magnitude of the wind/tornado threat.

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 0356 AM CDT Mon Sep 28 2026
Valid 011200Z - 061200Z
DISCUSSION
Thursday/Day 4 to Friday/Day 5
On Thursday, a mid-level trough is forecast to move through the southern Plains. Ahead of the trough, an axis of moderate instability is forecast to be in place Thursday afternoon from central Texas north-northeastward into southwest Missouri. Thunderstorm development is expected along and near parts of the instability axis during the afternoon and evening. The area with the greatest potential for severe storms appears to be across central Texas, where current model forecast have moderate instability and moderate deep-layer juxtaposed. However, the favored corridor is forecast to be narrow, and there is some uncertainty concerning the placement of the instability axis. Severe wind gusts and hail will be possible with storms that form near the instability axis Thursday afternoon and evening.
Thunderstorms will again be possible ahead of the trough on Friday, from parts of the mid Mississippi Valley southwestward into the Ark-La-Tex. Along this corridor, an isolated severe threat will be possible with storms that develop near localized maximums of instability. However, deep-layer shear is forecast to be relatively weak, suggesting that any severe threat will remain marginal.
Saturday/Day 6 and Monday/Day 8
From Saturday to Monday, an upper-level trough is forecast to move from the northern Plains into the Northeast. At the surface, a cold front is forecast to advance southward from the Mid Mississippi and lower Ohio Valleys to near the Gulf Coast. Scattered thunderstorms will be possible each day ahead of the front, with the greatest convective coverage in the Southeast. Deep-layer shear is expected to remain relatively weak across the moist sector, which should minimize the potential for severe storms.
