Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1237 AM CDT Fri Oct 09 2026
Valid 091200Z - 101200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE FLORIDA PANHANDLE…SOUTHEAST ALABAMA AND SOUTHWEST GEORGIA
### SUMMARY
Thunderstorms associated with Hurricane Isaias will have potential to produce tornadoes from this afternoon into the overnight period from the Florida Panhandle into southeast Alabama and southwest Georgia.
Florida Panhandle/Southeast Alabama/Southwest Georgia
The National Hurricane Center is forecasting Isaias to make landfall near Pensacola early this evening. As the center of Isaias approaches the Gulf Coast this afternoon, rainbands will spread across the Florida Panhandle. Within these bands, thunderstorms will develop and move inland. The airmass ahead of these bands is forecast to be very moist and unstable. Surface dewpoints in the mid to upper 70s will contribute to moderate instability, with MLCAPE likely peaking in the 1500 to 2000 J/kg range along parts of the coast. RAP forecast soundings in the Florida Panhandle to the east of Isaias’ center early this evening suggest that 0-3 km storm-relative helicity will increase to around 200 m2/s2, which will support rotating storms with potential to produce tornadoes. The tornado threat is expected to persist into the overnight period as the rainbands associated with Isaias move northward into southern Alabama and southwest Georgia.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 PM CDT Thu Oct 08 2026
Valid 101200Z - 111200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SATURDAY ACROSS PARTS OF THE FLORIDA BIG BEND/PANHANDLE AND EASTERN ALABAMA INTO GEORGIA
### SUMMARY
A corridor of tornado risk may develop out of the Florida Panhandle and into parts of eastern Alabama and Georgia Saturday through Saturday night.
Discussion
Models indicate considerable further amplification of large-scale mid/upper troughing along much of the U.S. Pacific coast Saturday through Saturday night. It appears that this may include the east-northeastward acceleration of a short wave trough into/across southern California and northern Baja coastal areas, preceded by the inland acceleration of remnants of Rachel into the lower Colorado Valley by 12Z Sunday.
Downstream, broad mid/upper ridging is forecast to build within the stronger mid-latitude westerlies, east of the Rockies through the Atlantic Seaboard. However, within a lingering weaker branch of westerlies, a developing mid-level low, including remnants of Isaias, is forecast to begin gradually turning northward and northeastward, around the northwestern periphery of westward building mid/upper ridging across the subtropical western Atlantic through the northern Caribbean and southeastern Gulf Basin.
Southeast
The weakening low-level circulation center of Isaias is forecast to continue accelerating northward, across western Alabama during the day Saturday, before slowing across the lower Tennessee Valley Saturday night. As it progresses away from the Gulf coast, and increasingly displaced from the better low-level moisture return off the Gulf, the associated risk for severe weather seems likely to diminish.
Guidance suggests that the return of higher low-level moisture content will remain focused along/east of weak surface troughing, developing along the southwestern flank of a surface ridge slowly shifting across and offshore of middle/northern Atlantic coastal areas. It appears that this will generally set up across Georgia into parts of the Carolinas, where boundary-layer dew points increasing into the 70s F probably will contribute to at least modest CAPE on the order of 1000+ J/kg, despite weak lapse rates. Coupled with the maintenance of at least moderate southerly 850 flow, and enlarged low-level hodographs, forcing for ascent downstream of the approaching mid-level low/trough may support continuing convective development, including supercell structures, Saturday into Saturday night. Some of this activity may pose a risk for tornadoes and/or locally damaging wind gusts.
Due to lingering forecast uncertainties, including those associated with the extended time frame involved, the Slight Risk area has not been changed at the present time. However, this may need to be adjusted in later outlooks for this period.

Outlook for Sunday, October 11

any severe predictability too low
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 0321 AM CDT Thu Oct 08 2026
Valid 111200Z - 161200Z
DISCUSSION
On Sun/D4, a shortwave trough and surface low (previously associated with the tropical cyclone) will move east across the TN/OH Valleys, and toward the Mid Atlantic Sunday night. A warm front and northward surge of moisture will occur from GA/Carolinas into VA/DelMarVa, resulting in at least a few hundred J/kg MLCAPE. Substantial rain and thunderstorms are likely to exist over the region, and therefore boundary layer warming/destabilization is in question. Most models show little if any daytime heating. As such, predictability is low at this time, but at least low severe probabilities could be added in later outlooks as the scenario evolves.
To the west, a shortwave trough with tropical remnants will affect southern CA and AZ, with strong southwest winds aloft. Substantial model differences exist regarding destabilization due to increasing clouds and rain, though some severe wind and even hail potential cannot be ruled out where instability is locally higher. This area too may see at least low severe probabilities in later outlooks as predictability increases.
For the remainder of the period through Thu/D8, a potential western trough ejection may occur into the Plains, with the strongest instability on or after Wed/D7 as moisture return becomes more established with upper 60s F dewpoints possible from TX into OK and KS. As such, this area will also be monitored as the event nears, and as trough timing becomes more predictable.
