Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0353 AM CST Sun Dec 03 2023 Valid 061200Z - 111200Z ...DISCUSSION... ...Wednesday/Day 4 and Thursday/Day 5... An upper-level ridge is forecast to move across the central and eastern U.S. on Wednesday and Thursday. A relatively dry and cool airmass over the continental United States will make conditions unfavorable for thunderstorms in most areas. ...Friday/Day 6 to Sunday/Day 8... An upper-level trough is forecast to dig southeastward into the Four Corners region Friday. Ahead of the system, moisture advection will take place in the southern Plains. As the system moves into the south-central states Friday night, thunderstorm development will be possible along a low-level jet from the Ark-La-Tex northeastward into the mid Mississippi Valley. New model runs have the system moving to the east faster, which should limit the amount of time for moisture to return. For this reason, the stronger instability Friday night should be confined to east Texas. Severe storms could occur there but any threat should remain isolated. On Saturday and Sunday, the latest model runs now have a different and much faster solution. The system is forecast to move quickly across the Southeast over the weekend. Thunderstorms will be likely ahead of the trough, and a severe threat will be possible. However, due to a lack of run-to-run consistency, uncertainty appears considerable in the Southeast over the weekend. Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1226 AM CST Sun Dec 03 2023 Valid 031200Z - 041200Z ...NO CRITICAL AREAS... ...Synopsis... Enhanced west to northwesterly upper-level flow across the Rockies into the High Plains will support dry downslope flow in to the Central High and Southern Plains this afternoon. Relative humidity reductions to around 15-20 percent with sustained winds around 20-25 mph will overlap across the Texas/Oklahoma Panhandles into far western Texas. While fuels in these regions remain above seasonal average for moistness, some drying can be expected in dormant fine fuels. Given low confidence in status of fuels, no areas have been included with this outlook, though Elevated meteorological conditions are possible. ..Thornton.. 12/03/2023 ...Please see www.spc.noaa.gov/fire for graphic product...
