Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0654 AM CST Fri Dec 12 2025
Valid 121300Z - 131200Z
NO THUNDERSTORM AREAS FORECAST
### SUMMARY
Thunderstorms are not forecast across the U.S. today or tonight.
Discussion
Cold/continental trajectories especially east of the Rockies will generally preclude thunderstorm development. Regarding a potential exception, gradual low-level moisture return will continue to occur over the western Gulf toward coastal Texas ahead of a low-latitude trough over northern Mexico. Convection will probably develop and increase late tonight over the western Gulf, but modest forcing for ascent and marginal thermodynamic profiles aloft should limit thunderstorm potential over inland areas of Texas.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1159 PM CST Thu Dec 11 2025
Valid 131200Z - 141200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Isolated weak thunderstorm activity is possible across South Florida and the Keys Saturday afternoon into Saturday night.
Synopsis
The large-scale pattern on Saturday will feature a ridge across the western CONUS with troughing across the east. This mid-level trough will amplify on Saturday as a strong mid-level jet streak moves from the northern Plains to the Midwest. At the surface, a cold front will sharpen from the Ohio Valley to the Plains and move south rapidly Saturday evening.
South Florida
Tropical moisture will start to advect northward across the southern Florida Peninsula on Friday. If this advects far enough north during the day, a few thunderstorms may be possible on the eastern sea breeze. During the overnight period, storm chances will increase across the western Florida Peninsula as a mid-level shortwave trough traverses the Gulf. Limited instability should preclude any severe weather threat from this activity.
Shallow convection may develop along the southward moving cold front from southeast Texas to central Alabama late Saturday night, but warm temperatures aloft should limit lightning potential.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0211 AM CST Fri Dec 12 2025
Valid 141200Z - 151200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
A few storms are possible across South Florida and the Florida Keys on Sunday.
Synopsis
A mid-level trough will advance from the Great Lakes to the western Atlantic on Sunday. To the west, a ridge will remain centered across the western CONUS. On the eastern periphery of this ridge, a secondary mid-level shortwave trough will move into the Upper Midwest. A very strong (1040mb+) area of high pressure will build into the eastern 2/3rds of the CONUS Sunday and push a strong cold front into the Gulf by Sunday evening.
South Florida
A weak mid-level shortwave trough will approach the west coast of Florida on Sunday morning. As this trough advances east, isolated to widely scattered thunderstorms are possible across far south Florida. Weak lapse rates should limit storm intensity overall. Storms should wane by the evening as the boundary layer cools and northerly flow strengthens and brings cooler, drier air by Sunday night.

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 0319 AM CST Fri Dec 12 2025
Valid 151200Z - 201200Z
DISCUSSION
Strong high pressure will dominate the eastern CONUS on Monday with offshore flow across then entire Gulf Coast and East Coast. This dry, continental polar airmass across the eastern CONUS will result in no thunderstorms east of the Rockies on Monday and Tuesday. Some thunderstorms are possible along the coastal Pacific Northwest where some weak instability may be present.
By the middle of next week, moisture return should resume across Texas. This may result in some thunderstorm activity by early Wednesday in the east Texas vicinity. Beyond Wednesday, model uncertainty increases substantially. However, severe potential will still remain too low as even the most favorable mid-long range guidance indicates minimal instability and low severe weather threat.
