Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1151 PM CST Wed Nov 04 2026
Valid 051200Z - 061200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe storms are unlikely today and tonight.
Synopsis
An upper low over the Great Lakes is forecast to strengthen through the day today as it merges with a weaker shortwave trough emanating from the mid MS Valley. East of the mid-level cyclone, a belt of enhanced southerly flow aloft will gradually overspread portions of the Appalachians and Atlantic Seaboard into the evening and overnight hours. A broad surface low over the lower St Lawrence valley will weaken as a second low forms over the eastern Great Lakes. An associated diffuse cold front is forecast to move slowly southeastward across the Appalachians toward the Atlantic Coast.
Carolinas to the Mid Atlantic
Ahead of the cold front a moist air mass will remain in place with dewpoints in the mid 60s F. Low-level warm air advection will favor cloudiness and only modest buoyancy with continued weak southerly surface winds. The stronger flow aloft is expected to arrive later in the diurnal cycle and will mainly be focused behind the cold front. Given the weak overall forcing and modest buoyancy, relatively isolated showers and thunderstorms are expected. Additional storms may develop along the front later in the evening, but little severe potential is expected owing to the weak buoyancy and poor overlap with stronger vertical shear.
Southern New England
Farther north, a moist but cooler boundary layer will likely be in place ahead of the cold front from MA to southern NY. The humid environment could support very weak buoyancy immediately ahead of the front amid strengthening flow aloft. Frontal forcing is not expected to be overly strong, but could support a shallow convective band ahead of the front late in the evening and overnight. Some potential may exist for intermittent strong gusts to reach the surface, but confidence remains quite low.
OK/TX
A weak vorticity max will move across OK on the southwestern flank of the larger-scale eastern trough. Cool mid-level temperatures will support weak elevated instability, with a few thunderstorms expected through the day and into the evening. Scattered elevated thunderstorms are also expected over Deep South TX, as the southern end of the cold front undercuts a moist air mass near the Gulf. Weak shear and buoyancy should preclude a severe risk.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0110 PM CST Wed Nov 04 2026
Valid 061200Z - 071200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE EASTERN CAROLINAS AND SOUTHEAST VIRGINIA
### SUMMARY
A few strong to severe storms are possible Friday over parts of the eastern Carolinas and southeast Virginia.
Eastern NC and vicinity
An upper low and attendant trough oriented from the Great Lakes to the TN Valley will become more progressive on Friday, shifting east toward the Eastern Seaboard and New England. This will bring a belt of enhanced southwesterly deep-layer flow across the Carolinas, northward through the Northeast. At the surface, low pressure will deepen over the Mid-Atlantic and move offshore through the period, with a trailing front shifting east across eastern VA/NC/SC/GA and northern FL.
Ahead of the front, mid-60s F dewpoints will be in place as far north as southeast VA. This will aid in weak destabilization across the eastern Carolinas toward southeast VA within the pre-frontal warm advection regime. However, cloudiness and possible ongoing showers/thunderstorms across portions of the region will inhibit stronger destabilization despite cooling aloft and favorable boundary layer moisture. Nevertheless, strengthening vertical shear is anticipated by midday, and where pockets of stronger heating/destabilization can occur, isolated strong to severe storms will be possible. These stronger storms could produce sporadic wind damage, and a Level 1/Marginal risk has been included with the Day 3 update.

NOTE: THE NEXT DAY 3 OUTLOOK IS SCHEDULED BY 0830Z
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 0318 AM CST Wed Nov 04 2026
Valid 071200Z - 121200Z
DISCUSSION
For the Sat/D4 through Wed/D8 period, thunderstorm potential will be minimal across the U.S. due to a lack of instability. An upper trough will exit the eastern U.S. on Sat/D4, with high pressure over most of the CONUS. Multiple shortwave troughs are forecast to dig southeastward across eastern Canada and into the northeastern states, maintaining a cool and stable pattern. Any appreciable instability will remain offshore, with little if any severe potential expected.
