THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM SOUTHEAST TEXAS TO THE CENTRAL GULF STATES
### SUMMARY
Severe thunderstorms are expected across southeast Texas into the central Gulf states.
Southeast Texas to Central Gulf States
Midlevel speed max is forecast to translate through the base of the Four Corners trough into southeast NM at the start of the period before advancing into central OK by early evening. Subsequently, this feature will eject into southeast MO by 10/12z in response to a northern stream trough digging into the upper MS Valley overnight.
Late this evening, surface front had progressed to a position from western IL-northern AR-southern OK. This boundary should continue sagging south, and 00z model guidance suggests a weak surface wave will develop along the trailing boundary over south-central TX by early afternoon. Some deepening should occur as a weak surface low advances across northern LA into MS late in the period. Early in the day the primary focus for convection will be along the cold front across the lower OH/TN Valley region into the lower MS Valley, primarily driven by low-level warm advection beneath a modest LLJ. While this early-day convection may pose some risk for damaging gusts and perhaps a tornado, the primary concern will occur later in the day as the secondary speed max ejects across the southern Plains toward southern MO.
Current thinking is elevated thunderstorms should develop ahead of the ejecting speed max/short wave by 18z across south central TX. This initial activity will likely be elevated, but as storms advance downstream surface-based parcels will have negligible inhibition near the lower Sabine River Valley. Hail/wind will be the primary concern early with supercells. During the evening a marked increase in the LLJ is expected across the lower MS Valley into northern AL overnight. As convection advances east, stronger low-level shear will favor some risk for tornadoes. While supercells are expected, a considerable amount of convection is expected along the synoptic warm front, and this should limit northward extent of higher instability air mass.
At this time it does not appear necessary to increase severe probabilities across the lower MS Valley into the central Gulf states, primarily due to the short wave ejecting well north of the higher-instability air mass.

THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHEAST…CAROLINAS AND SOUTHERN VIRGINIA
### SUMMARY
Isolated severe thunderstorms are possible on Saturday from the Southeast into parts of the Carolinas and southern Virginia.
Southeast/Carolinas/Southern Virginia
At the start of the period, a large-scale upper-level trough will be located from the southern Plains to the Upper Midwest, with an associated 80 to 100 knot mid-level jet over the mid-Mississippi and lower Ohio Valleys. The southern edge of the stronger mid-level flow will be over the Southeast, where a moist airmass will be in place Saturday morning. Within this airmass, low-level convergence ahead of a cold front will contribute to the development of scattered to numerous thunderstorms from the lower Mississippi Valley northeastward into the southern Appalachians. Weak instability along the moist axis along with moderate deep-layer shear, will likely be sufficient for an isolated severe threat early in the day. This threat is expected to develop into parts of the Carolinas and southern Virginia by midday, as a low-level jet translates northeastward. A brief tornado could occur near the low-level jet. However, the primary threat should be wind damage with the stronger short line segments. Lapse rates are forecast to remain poor, which should keep any severe threat marginal.

NOTE: THE NEXT DAY 2 OUTLOOK IS SCHEDULED BY 1730Z
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:

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0316 AM CST Thu Jan 08 2026
Valid 111200Z - 161200Z
DISCUSSION
Organized severe potential currently appears low through the extended-range period.
A cold front will move through coastal NC and parts of FL on D4/Sunday, in advance of a deep upper trough moving across the eastern CONUS, but ascent and buoyancy within the remaining warm sector appear too weak to support organized storms. For D5/Monday through D8/Thursday, generally dry and stable conditions in the wake of multiple frontal intrusions will tend to limit thunderstorm potential across most of the CONUS. Some guidance (notably the 00Z ECMWF) indicates that thunderstorm chances may return to parts of the FL Peninsula by mid week, in association with renewed upper trough amplification across the eastern CONUS. However, with guidance generally depicting only weak surface wave development during this time frame, confidence in organized storm development remains low.
