Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0640 AM CST Mon Nov 09 2026
Valid 091300Z - 101200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Organized severe thunderstorms are not forecast through tonight.
Synopsis and Discussion
Generally elevated thunderstorms are ongoing this morning across parts of south TX to the north of a weak inverted surface trough. This convection is being aided by large-scale ascent and modest low-level warm advection occurring ahead of a weak upper trough over west TX/northern Mexico. Weak MUCAPE and poor lapse rates aloft are expected to limit the severe threat this morning (reference the 12Z observed CRP/BRO soundings). Also, the potential for surface-based thunderstorms over land appears lower than yesterday, and any stronger thunderstorms should tend to focus offshore through the morning into early afternoon.
Another fast-moving upper trough is forecast to overspread the Pacific Northwest this afternoon through tonight. Surface dewpoints in the upper 40s to low 50s and filtered daytime heating should allow MUCAPE up to 100-300 J/kg to develop along/ahead of a low-topped band of convection expected to move quickly eastward across coastal WA/OR this afternoon. Occasional lightning flashes may occur with this activity, as mid-level temperatures will be fairly cold. While strong low/mid-level winds veering with height appear conditionally favorable for organized updrafts, the meager instability should tend to limit the risk for severe gusts.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1236 AM CST Mon Nov 09 2026
Valid 101200Z - 111200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
No severe threat is forecast across the U.S. Tuesday and Tuesday night.
DISCUSSION
At mid-levels, west-northwesterly flow will remain in place on Tuesday across much of the U.S. Within the flow, a shortwave trough will move eastward across the southern Plains. Ahead of the trough, isolated thunderstorms will be possible along the Texas Gulf Coast from Tuesday into Tuesday night. No severe threat is expected, and no thunderstorms are forecast across the remainder of the continental U.S.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0117 AM CST Mon Nov 09 2026
Valid 111200Z - 121200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
No severe threat is forecast across the U.S. Wednesday and Wednesday night.
DISCUSSION
At upper-levels, a ridge will move eastward across the western U.S. on Wednesday, as a trough and an associated cold front move southeastward into the mid Mississippi Valley. Ahead of the front, thunderstorms will be possible in the afternoon from Illinois southward into western Tennessee. A strong wind gust are two will be possible along this narrow north-to-south corridor. However, no appreciable severe threat is expected. Elsewhere, thunderstorm development will be possible near the coasts of southeast Texas and southwest Louisiana. Scattered storms will also be possible over parts of the Florida Peninsula. No severe threat is expected.

NOTE: THE NEXT DAY 3 OUTLOOK IS SCHEDULED BY 1930Z
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:

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0137 AM CST Mon Nov 09 2026
Valid 121200Z - 171200Z
DISCUSSION
On Thursday/Day 4, an upper-level trough is forecast to move into the eastern U.S., as an associated cold front advances southeastward to near the Atlantic coasts of the Carolinas and Georgia. Thunderstorm development will be possible along the front and ahead of the trough in the Mid-Atlantic. Isolated strong wind gusts will be possible, but any potential for severe gusts should be minimal due to weak instability. From the weekend into early next week, a large area of high pressure is forecast to move across the central and eastern U.S. In response, a cold and dry airmass is expected to settle in over much of the continental U.S., which will be unfavorable for thunderstorm development in most areas.
