Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1003 AM CST Mon Dec 15 2025
Valid 151630Z - 161200Z
NO THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected today or tonight.
Synopsis
Thunderstorm potential will remain low today as strong surface high pressure and cut-off Gulf moisture results in a dry/stable airmass across much of the CONUS. A weak shortwave impulse will move over portions of the Pacific Northwest today/tonight. A few lightning flashes will be possible offshore, but minimal instability and generally shallow convection will preclude stronger updrafts through sufficiently cold temperatures aloft to produce thunderstorms inland.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1021 AM CST Mon Dec 15 2025
Valid 161200Z - 171200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected tomorrow (Tuesday).
Synopsis
A series of mid-level troughs will traverse the northern CONUS tomorrow (Tuesday), prompting surface troughing across the central U.S., and the Pacific Northwest. Cool temperatures aloft will overspread the northern OR into WA coastline areas, promoting scant buoyancy amid deep-layer ascent to support the potential for a few lightning flashes. Across the western Gulf Coast, adequate return flow of moisture, driven by aforementioned surface troughing, will support marginal buoyancy and associated potential for isolated thunderstorms early Wednesday morning.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CST Mon Dec 15 2025
Valid 171200Z - 181200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
A few isolated thunderstorms are possible in the Texas Coastal Plain Wednesday morning. Scattered thunderstorms are possible early Thursday morning from the Ozarks to the Lower Ohio River Valley.
Synopsis
A strong mid-level jet streak and associated shortwave trough over the Pacific Northwest on Wednesday morning will move quickly across the Rockies and amplify as it enters the Plains late Wednesday into early Thursday morning. A very strong surface low, associated with this fast-moving trough, will move from British Columbia Wednesday morning to the Upper Midwest by early Thursday morning.
A few thunderstorms may persist early Wednesday within a region of weak isentropic ascent across East Texas. However, as the low-level jet veers/weakens, this threat is expected to wane. High pressure will continue to dominate much of the daytime period across the eastern CONUS which should limit any thunderstorm potential. However, by Wednesday night, thunderstorm potential is expected to increase from the Texas Coastal Plain to the Lower Ohio River Valley. As the mid-level trough amplifies across the Plains, a low-level jet will rapidly strengthen from East Texas to the Ozarks. This will advect low-level moisture northward during the evening. After 06Z, weak to potentially moderate elevated instability is expected within a broad region of weak isentropic ascent from Arkansas to southern Illinois. Effective shear (based on an elevated parcel) is expected to remain very weak early Thursday morning as the primary mid-level jet streak is not forecast to emerge over the warm sector until later Thursday morning. Therefore, no severe weather is anticipated on Day 3/Wednesday.

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 0349 AM CST Mon Dec 15 2025
Valid 181200Z - 231200Z
DISCUSSION
D4/Thursday - Mid-Mississippi Valley and Lower Ohio Valley to the Southeast
Isolated severe storms are possible on Thursday as moisture expands northward ahead of a strong cold front. Forecast soundings show strong shear across the region, but limited instability as 60+ F dewpoints struggle to make it north of I-20. Given the strength of the low-level jet, some damaging wind gusts are possible, but a greater threat is not anticipated due to the aforementioned limited instability.
D5/Friday - Carolinas to Georgia Coast
Thunderstorms may be ongoing near the Carolina/Georgia coast on Friday morning, but will quickly move into the Atlantic as a cold front advances eastward. In addition, this front will move into the Gulf and push rich moisture well offshore. As a result, thunderstorm potential should be limited for the remainder of the D5 period.
D6/Sat-D7/Sun - TN Valley into the Southeast
Return flow will resume once again across the western Gulf over the weekend. 60F dewpoints are expected to advect inland across East Texas and Louisiana. This richer moisture may eventually interact with a southeastward moving cold front at the end of D6 and into D7 with some thunderstorm potential. A few stronger storms may be possible if sufficient instability can develop.
