Overview of the threat for the next few days
Outlook for Tuesday, September 22
Outlook Summary
An isolated threat for severe wind gusts is expected today in Utah into southwest Wyoming and western Colorado. Thunderstorms capable of strong to locally severe damaging gusts are also possible across parts of the Southeast.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0722 AM CDT Tue Sep 22 2026
Valid 221300Z - 231200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR MUCH OF UTAH INTO ADJACENT PARTS OF WYOMING AND COLORADO…AND ACROSS A PORTION OF THE SOUTHEAST
### SUMMARY
An isolated threat for severe wind gusts is expected today in Utah into southwest Wyoming and western Colorado. Thunderstorms capable of strong to locally severe damaging gusts are also possible across parts of the Southeast.
Utah into southwest Wyoming and western Colorado
Water-vapor imagery this morning shows a potent mid-level trough over the western Great Basin. This upper feature and an accompanying speed max —beginning to be sampled by the Cedar City, UT WSR-88D VAD (KICX)— are forecast to move northeast across UT through early evening. In the wake of early day showers and a few thunderstorms associated with an initial lobe of ascent, some heating will yield steepened 0-2 km lapse rates and the development of marginal buoyancy. As storms develop and intensify, elongated hodographs will support a few stronger cells to be capable of marginally severe hail. However, 60 to 75 mph gusts on an isolated basis will likely be the primary severe hazard. This activity will eventually move into western CO and southwest WY towards the late afternoon/early evening with severe gusts potentially in proximity to stronger cores and outflow. ### Southeast
A slow-moving cold front will aid in focusing thunderstorms across portions of the Deep South into the southern Appalachians. Heating of a moist airmass featuring upper 60s to lower 70s deg F surface dewpoints will likely result in 1500-2500 J/kg MLCAPE by early to mid afternoon. Weak low to mid tropospheric flow will limit overall storm vigor, but some of the stronger water-loaded downdrafts will probably be capable of strong to locally severe gusts and pockets of wind damage into the early evening.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1237 AM CDT Tue Sep 22 2026
Valid 231200Z - 241200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected tomorrow (Wednesday).
Synopsis
An upper low will meander over the eastern U.S. while an upper ridge builds over the Plains states, and an upper trough gradually amplifies over the Pacific Northwest tomorrow (Wednesday). Surface high pressure will build over the northeastern U.S. and Interior West, limiting severe thunderstorm potential. One small exception may be along the windward side of the southern Appalachians, particularly over eastern TN. Here, a surface inverted trough will allow low-level moisture to advect northward, with mid 60s F dewpoints boosting MLCAPE to near 1000 J/kg (albeit tall and thin profiles). A mid-level impulse and accompanying 30+ kt 500 mb jet will yield modestly elongated hodographs and 30 kts of effective bulk shear. CAM guidance consensus depicts pulse cellular and multicellular development by afternoon. An instance of hail approaching 1 inch in diameter or a strong gust causing tree/wire damage cannot be ruled out.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0218 AM CDT Tue Sep 22 2026
Valid 241200Z - 251200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected on Thursday.
Synopsis
Upper troughing will prevail over the East and West Coasts while upper ridging continues over the Plains states. West of the Rockies, an embedded mid-level impulse will track northeastward across the Southwest, bringing widespread showers and widely scattered thunderstorms. However, buoyancy and shear should be too meager to support an organized severe 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 0255 AM CDT Tue Sep 22 2026
Valid 251200Z - 301200Z
DISCUSSION
Upper ridging across the Plains and upper troughing over the western and eastern U.S. will persevere through the weekend, before a more progressive pattern takes shape and an upper trough ejects into the Plains states early next week. Through the weekend, thunderstorm chances should remain confined to the High Plains and points westward, with little indication of an organized severe threat. By early next week, there is some consensus among medium-range deterministic guidance of a surface low developing over the central Plains, encouraging low-level moisture advection beneath cooling temperatures and increasing west-southwesterly flow aloft. However, guidance does not show a favorable overlap of instability or vertical wind shear, with AI/ML calibrated guidance also not depicting a signal for severe, so probabilities have been withheld this outlook.
