Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0110 PM CST Wed Dec 10 2025

NO THUNDERSTORM AREAS FORECAST
### SUMMARY
Thunderstorms are not forecast through tonight.
No changes.

.PREV DISCUSSION… /ISSUED 1021 AM CST Wed Dec 10 2025/
Synopsis and Discussion
A shortwave trough, and accompanying intense jet streak with 500 mb winds over 100 kt, will continue eastward through the OH Valley today and off the Northeast coast by early tomorrow. Surface low associated with this wave will progress northeastward from its current position over southeastern Lower MI/southwestern Ontario along the St. Lawrence Valley today, continuing through ME and into the Canadian Maritimes by early tomorrow. An extensive cold front extending southeastward from this low will push quickly eastward/southeastward through the southern Plains and much of the eastern CONUS, ending the period well off the East Coast.
Passage of this cold front will reinforce the dry and stable conditions across the majority of the CONUS, precluding thunderstorms. Modest low-level moisture will remain over central/southern FL throughout the day, but warm low to mid-level temperatures will prohibit deep convection, limiting the thunderstorm potential.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1052 AM CST Wed Dec 10 2025
Valid 111200Z - 121200Z
NO THUNDERSTORM AREAS FORECAST
### SUMMARY
Thunderstorms are not expected on Thursday.
Synopsis
A broad expanse of northwesterly flow aloft will stretch from the Pacific Northwest to the Southeast on Thursday as an upper ridge builds over the eastern Pacific and an upper trough moves offshore the Atlantic coast. Prior surface cold frontal intrusions into the Gulf will leave a dearth of boundary layer moisture east of the Rockies. With a dry and stable boundary layer in place, thunderstorms are not expected.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1229 PM CST Wed Dec 10 2025
Valid 121200Z - 131200Z
NO THUNDERSTORM AREAS FORECAST
### SUMMARY
Thunderstorms are not expected on Friday.
Synopsis
An amplified upper ridge over the eastern Pacific will meander east through the forecast period while broad upper troughing persists across the eastern U.S. At the surface, a weak low over the Ohio Valley Friday morning will move offshore the Mid-Atlantic coast late Friday night/early Saturday morning. A trailing cold front will develop south across TX and the Lower MS Valley. While modest boundary layer moisture will reside across the TX coastal plain, any appreciable instability will remain offshore over the western Gulf. A few thunderstorms could occur late in the forecast period offshore, but any lighting activity along the coast and immediately inland should remain limited.

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 0314 AM CST Wed Dec 10 2025
Valid 131200Z - 181200Z
DISCUSSION
Based on the latest medium-range model output, a vigorous digging short wave trough is likely to contribute to substantive mid-level trough amplification once again across the Upper Midwest/Great Lakes and Ohio Valley, into and across the Mid Atlantic Seaboard this coming weekend. It appears that this may provide support for significant cyclogenesis along a frontal zone across the northwestern Atlantic, while a strongly confluent mid-level regime in its wake supports the southeastward development of a large cold surface ridge across most areas east of the Rockies, including the offshore Atlantic and Gulf Basin by early next week.
Thereafter, into the middle of next week, mid-level flow may trend a bit more zonal, at least across the northern mid-latitudes of North America. However, there is notable spread evident within and among the various model output concerning short waves emerging from the upstream blocking pattern, before progressing inland within splitting branches of westerlies across and east of the Rockies. After an initial suppression of Gulf boundary-layer moistening early next week, a developing southerly return flow with moistening that may lead to increasing convective potential appears possible across and northeast of the northwestern Gulf coast/lower Mississippi Valley vicinity. The extent to which this could include a risk for severe storms remains unclear, but currently still appears generally low through at least this period.
