Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0730 PM CDT Sat Sep 26 2026
Valid 270100Z - 271200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PORTIONS OF WESTERN OKLAHOMA AND NORTHWEST TEXAS
### SUMMARY
Isolated hail and strong outflow winds may accompany thunderstorms across portions of the southern Plains this evening into the overnight.
Synopsis
Scattered thunderstorms continue to develop this evening along a surface trough across western Oklahoma and northwest Texas, or along a myriad of outflow boundaries from prior convection (as is the case across southwest Oklahoma). The airmass ahead of these storms is still quite warm, with 90F temperatures as far north as portions of northwest Oklahoma. These warm surface temperatures are contributing to steep low-level lapse rates conducive to downward momentum transfer and isolated damaging thunderstorm outflows. Although the most likely threat will be strong, gusty winds, the degree of instability and strength of the cloud-layer vertical shear may support a marginally severe hail threat with the strongest cores.
This activity should continue into the evening hours before weakening low-level lapse rates and increasing surface-based inhibition diminishes the overall severe threat.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1211 PM CDT Sat Sep 26 2026
Valid 271200Z - 281200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected on Sunday.
Synopsis
A broad western trough will evolve into an upper low in central California with another weaker shortwave trough within the northern Rockies into Monday morning. A modest surface trough will extend from parts of the northern High Plains into the southern High Plains. While some low-level moisture will be maintained within the High Plains on the western flank of a surface high, overall moisture quality/depth will be limited. Furthermore, increasing cloud cover across much of these regions will limit the degree of destabilization that will occur. Capping is likely to limit storm development during the afternoon in the northeast Wyoming/Black Hills vicinity where a stronger storm would be conditionally possible otherwise. Later in the evening, a strengthening low-level jet in the northern Plains will promote scattered storm development. Mid-level lapse rates could support small hail. A weak surface low in the southern High Plains could allow isolated storms to initiate where surface heating will be greater than farther north. Weak shear should limit any organization of that activity. Overall severe potential appears low across the CONUS.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0227 PM CDT Sat Sep 26 2026
Valid 281200Z - 291200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected on Monday.
Synopsis
An upper low will continue to move eastward into the Lower Colorado Valley through Monday/early Tuesday. This will be separate from a stronger belt of upper-level winds across the northwestern/north-central U.S. Moisture within the Plains will be maintained by low-level southerly flow. A weak surface low is expected near the Black Hills. As this low/trough evolves through the day, a cold front will move southeastward into parts of the Dakotas. While some surface heating is possible in the vicinity of the front, increasing clouds/precipitation will generally keep surface temperatures cooler. Warmer air aloft should keep capping in place during the afternoon. Storm development is more likely after 00Z as the front begins to move southeastward and the low-level jet increases. Less than ideal diurnal timing, weak effective shear, and modest mid-level lapse rates will likely limit severe potential with this activity.

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 0629 AM CDT Sat Sep 26 2026
Valid 291200Z - 041200Z
DISCUSSION
An upper trough is poised to gradually track eastward across the Interior West and eject into the Plains states through next week. Surface low development is likely across the southern Plains sometime in the Days 5-6 (Wednesday-Thursday) time frame, when low-level moisture advection and accompanying buoyancy will appreciably increase. However, vertical wind shear is expected to be limited, so organized severe potential does not appear evident, though at least isolated severe is possible across the southern Plains around next Thursday. Thereafter, a cold front will progress southeastward across much of the CONUS, displacing buoyancy across much of the Plains and MS Valley, further limiting the severe threat.
