Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1229 AM CDT Wed Mar 11 2026
Valid 111200Z - 121200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE LOWER MISSISSIPPI VALLEY…ACROSS THE TENNESSEE/OHIO VALLEY INTO THE MIDDLE ATLANTIC
### SUMMARY
Isolated to scattered severe thunderstorms are expected today from the ArkLaTex and Lower Mississippi Valley northeastward through the Ohio Valley and Mid-Atlantic.
Ohio Valley/Middle Atlantic
Northern-stream trough is digging east-southeast across the northern Rockies/High Plains early this morning and should advance into the upper MS Valley by 18z as a 500mb speed max translates through the base of the trough, then increases in intensity as it moves across lower MI during the afternoon. Large-scale height falls will overspread the Great Lakes/OH-TN Valley region as southwesterly flow strengthens across the downstream warm sector. Latest model guidance suggests the sharp cold front associated with this feature will extend across lower MI-central IL-northern MO at the start of the period. This boundary will serve as a primary focus for thunderstorm development through the period. By mid day, the front will have surged into northwest OH-central IN and modest boundary layer heating is expected across the warm sector downstream.
Current thinking is modest destabilization will be noted across much of the OH/TN Valley such that MLCAPE values should be on the order of 1500 J/kg within a strongly sheared environment. Forecast soundings support this and supercells are expected to develop, in addition to possible line segments and clusters. Large hail is possible with supercells, along with damaging winds and a risk for a few tornadoes. This activity will spread east toward the Middle Atlantic by late afternoon.
Gulf States
Positive-tilt short-wave trough is shifting east across west TX/northeast Mexico. However, this feature is expected to become more negative tilt by late afternoon as it ejects toward the lower Sabine River Valley. Seasonally cool 500mb temperatures are noted with this feature and a focused 70kt midlevel jet is forecast to translate along the Gulf coast during the latter half of the period. Left-exit region of this jet will encourage ascent/deep convection. Latest guidance suggests a surface low may evolve in response, tracking from the upper TX coast, across southern LA into southern MS by 12/06z. Some LLJ response is also expected which should aid organized thunderstorms across the southern Gulf states. Strong shear favors severe winds along with a risk for tornadoes. Some consideration was given to increasing severe probabilities ahead of this feature. This may be done in later outlooks if conditions continue to evolve toward an organized squall line.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1231 AM CDT Wed Mar 11 2026
Valid 121200Z - 131200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
A couple of strong thunderstorms producing gusty winds are possible across parts of the Southeast on Thursday morning into early afternoon. However, severe thunderstorm potential appears low.
Southeast
An upper trough from the Great Lakes to the central Gulf Coast will pivot east, moving offshore the Atlantic Seaboard by late Thursday/early Friday. Thursday morning, a cold front will extend south/southwest from the Mid-Atlantic coast to southern AL. Scattered thunderstorms will be ongoing ahead of the front within a moist warm sector, mainly from the central portions of the Carolinas into southwest GA and the FL Panhandle. Mid and low-level lapse rates are forecast to remain modest (6-6.5 C/km), and limited heating downstream of the front through midday/early afternoon will be stunted by cloudiness. As a result, instability is expected to remain modest (500-750 J/kg MLCAPE). Deep-layer westerly flow parallel to the front will remain fairly robust, with 30-50 kt from 850-500 mb. Coupled with weak instability, a few stronger storms producing mainly gusty winds will be possible across portions of northern FL into southeast GA, and perhaps portions of coastal SC. The front should move offshore by mid-afternoon (arcing southwestward across north FL and the eastern Gulf). Overall, severe thunderstorm potential appears limited.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0144 AM CDT Wed Mar 11 2026
Valid 131200Z - 141200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected on Friday.
Synopsis
Broad upper troughing will persist over much of the U.S. on Friday. At the surface, a cold frontal intrusion into the Gulf of America will leave a dearth of boundary layer moisture east of the Rockies, and a cool/dry/stable airmass will be in place. The exception will be across south FL where a seasonally moist boundary layer will persist south of the diffuse surface boundary. Isolated thunderstorms will be possible across the southern Peninsula. However, modest vertical shear, poor lapse rates, and a lack of large-scale ascent will preclude severe thunderstorm potential.

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 0252 AM CDT Wed Mar 11 2026
Valid 141200Z - 191200Z
DISCUSSION
Days 4-6/Sat-Mon
An upper trough will begin to deepen as it moves over the northern Rockies and into the northern/central High Plains on Saturday/Saturday night. As this occurs, a lee cyclone will deepen as it shifts east across the central Plains toward the MO Valley by early Sunday. Modified Gulf moisture will return northward in response to increasing southerly low-level flow ahead of the surface cyclone and attendant cold front. Medium range guidance is in fairly good agreement that any deeper/higher quality moisture will remain confined to east TX and the immediate Gulf coast on Sunday. With northward extent into the Mid-South, Mid-MS and Lower OH, and TN Valleys, 50s F dewpoints appear more likely. The upper trough will intensify and shift east across the Midwest and south-central U.S. on Sunday, but stronger flow aloft will remain displaced from better quality moisture return. While some severe potential could develop from east TX into the Lower OH/TN Valleys as a strong cold front tracks east across the central U.S. on Sunday, probabilities appear less than 15 percent at this time.
This system will shift east across the eastern U.S. on Monday, though any severe potential along the East Coast appears low at this time as the primary forcing for ascent lags behind the surface front.
Days 7-8/Tue-Wed
An amplified upper ridge will build across the western U.S. during the end of Tuesday and Wednesday while upper troughing persists across the East. Surface high pressure and the prior cold frontal passage into the Gulf will leave a stable and dry airmass in place, precluding severe potential.
