Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0744 PM CDT Fri Oct 02 2026
Valid 030100Z - 031200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorm potential should remain low through the night.
01 UTC Update
Showers and the occasional thunderstorm will continue along and southeast of a slow moving frontal zone draped from the southern Plains northeast toward the Mid-Atlantic. Instability is rather limited to the south of this front owing to poor lapse-rates, and vertical shear is weak. Thus, while the occasional thunderstorm may occur, the severe potential is low.
Elsewhere, a couple of lightning strikes may occur toward sunrise across the north-central US. Here, a short-wave trough moving through the stronger mid-level flow will overhead, bringing with it modest large-scale ascent. Temperatures in the 40Fs to low 50Fs with dewpoints in the 40Fs should limit instability and the overall potential for more widespread thunderstorm coverage.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1224 PM CDT Fri Oct 02 2026
Valid 031200Z - 041200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
No severe thunderstorms are expected across the U.S. on Saturday.
Synopsis
A midlevel trough now over WA will progress eastward across the upper MS Valley tomorrow, accompanied by a surface cold front. Conditionally unstable midlevel lapse rates, in combination with sufficient midlevel moistening in the zone of ascent preceding the midlevel trough, will support the potential for elevated thunderstorms across the upper MS Valley. Elsewhere, a slow-moving front will extend from the Carolinas to the northwest Gulf and provide a focus for thunderstorm development. Severe storms are not expected as a result of deep, moist profiles and weak vertical shear.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0224 PM CDT Fri Oct 02 2026
Valid 041200Z - 051200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe storms are not forecast for Sunday.
Synopsis
A deep midlevel trough will move from the Great Lakes to New England, as upstream ridging persists from the Four Corners into the Great Basin. A previously stalled front will be reinforced and will begin to move southeastward across the southern states, in the wake of the Great Lakes midlevel trough. A moisture plume will persist along and ahead of the front, with sufficient buoyancy for embedded thunderstorms along and ahead of the front, in an environment with weak vertical shear. Elsewhere, isolated/diurnal convection with a few lightning flashes will be possible over the high terrain of southwest CO. Farther west, a weak midlevel trough over the eastern Pacific will approach northern CA/OR by late Sunday. There is low potential for enough moistening/ascent to support isolated lightning flashes. However, the threat appears sufficiently low to preclude adding a thunderstorm area for CA/OR in this update.

NOTE: THE NEXT DAY 3 OUTLOOK IS SCHEDULED BY 0730Z
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 0317 AM CDT Fri Oct 02 2026
Valid 051200Z - 101200Z
DISCUSSION
Severe storm potential from Monday/D4 to Friday/D8 is forecast to be minimal.
A deep upper trough will move across eastern Canada and the northeastern USA Mon/D4 into Tue/D5, with a cold front already offshore and high pressure building in from the west. Behind the ejecting upper trough, moderate northwest flow aloft will persist across the northern tier of states, with some trough amplification possible over the Great Lakes Wed/D6 into Fri/D8. That said, a minimally unstable air mass will exist over most of the CONUS, with little severe thunderstorm potential. A few stronger storms cannot be ruled out around Thu/D7 over the upper Midwest beneath the northwest flow regime, but this low-predictability scenario will depend heavily on enough moisture returning to the region. As such, no areas are currently forecast.
