Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1004 AM CST Sat Dec 13 2025
Valid 131630Z - 141200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected today or tonight.
Southeast TX/Southwest LA
Morning satellite loops confirm northward transport of low-level moisture into parts of the southern Plains and lower MS Valley. This trend will continue this afternoon and evening as a shallow surface cold front sags southward through the region. Model guidance suggests that weak but sufficient instability will develop after dark from southeast TX into southwest LA to result in a few pre-frontal thunderstorms. Shear is weak, and limited CAPE will preclude organized severe storms. However, small hail is possible in the strongest cores tonight.
FL
A low-latitude disturbance crossing the Gulf and a northward moisture flux ahead of it will contribute to thunderstorm potential across the Florida Keys/Florida Straits today, and also across the southern Florida Peninsula tonight. Severe thunderstorms are unlikely with these scenarios.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1111 AM CST Sat Dec 13 2025
Valid 141200Z - 151200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
A few storms are possible across South Florida and the Florida Keys, as well as the western Gulf Coast tomorrow (Sunday).
Synopsis
A pronounced mid-level trough will eject into the Atlantic as another upper trough approaches the Pacific Northwest tomorrow (Sunday). Surface high pressure and an associated statically stable airmass will overspread much of the CONUS east of the Rockies, limiting thunderstorm development over most locales. The best chance for any isolated thunderstorm development will be along a surface cold front. At the start of the period (12Z Sunday), a few thunderstorms may develop along the cold front across the western Gulf Coast as the front encounters low-level moisture and moves offshore. Later in the day, the cold front will encounter a low-level moisture-driven, marginally unstable airmass across the southern FL Peninsula/FL Keys, where isolated thunderstorms will also be possible.
Across the Pacific Northwest, cooler temperatures aloft (and accompanying scant buoyancy) will impinge on the shoreline toward the end of the period (06-12Z Monday morning). While a couple of lightning flashes may occur during this time frame, the current thinking is that the overall coverage of lightning will likely be too sparse to warrant thunder probabilities at this time.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0117 AM CST Sat Dec 13 2025
Valid 151200Z - 161200Z
NO THUNDERSTORM AREAS FORECAST
### SUMMARY
Thunderstorms are not expected on Monday.
Discussion
Strong high pressure will dominate much of the eastern 2/3rds of the CONUS on Monday with strong offshore flow into the Atlantic and the Gulf, pushing rich moisture well offshore. Therefore, thunderstorm activity is not expected across much of the CONUS. The only exception may be across the Pacific Northwest coast where some weak instability may develop. However, even within this area, lightning activity should remain limited due to relatively warm air aloft.

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 0246 AM CST Sat Dec 13 2025
Valid 161200Z - 211200Z
DISCUSSION
Moisture return will begin on Tuesday/D4 across Texas with some weak instability and thunderstorm potential arriving by Wednesday/D5. Significant differences in the upper-level pattern begin on Thursday/D6 and beyond which will significantly impact thunderstorm and severe weather potential.
The ECMWF and AIFS have a sharper mid-level trough farther south on Thursday/D6. This will result in a stronger cold front and farther north moisture return ahead of the front. In addition, some weak instability may develop beneath the stronger mid-level jet. This may create an environment favorable for a few stronger storms from the Lower Ohio Valley to the Mid-Mississippi Valley. This stronger scenario would likely push a strong cold front deep into the Gulf on Friday and limit thunderstorm potential into the weekend.
A less amplified solution (as shown by the GFS and AIGFS) would not support much of any strong storm threat on Thursday/D6. However, it would keep low to mid 60s dewpoints across Texas and the Lower MS Valley on Friday and into the weekend. This may result in weak to potentially moderate instability across portions of the southern Plains and possibly into the Mid-Mississippi Valley through the weekend. Despite this lingering instability, a mostly zonal mid-level pattern would not support a significant severe weather threat.
Overall, severe weather potential remains somewhat low for much of the period. Some low-end severe weather threat may exist from Thursday/D6 and beyond as low-level moisture increases, but significant uncertainties in the evolution of the upper-level pattern make any forecast for time or location of any potential low-end threat difficult.
