SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0634 PM CST Sat Nov 30 2024 Valid 010100Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected through tonight. ...Discussion... High-amplitude cyclonic flow aloft will prevail across the eastern 2/3 of the U.S. tonight, while surface high pressure prevails east of the Rockies -- reflective of a polar airmass. Given the cold/dry continental conditions, thunderstorms are largely not anticipated. The only exception may be in lee of the Great Lakes, where a lightning flash cannot be ruled out in intense lake-effect snow bands. Still, threat remains too low for inclusion of a thunder area. ..Goss.. 12/01/2024 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0409 PM CST Sat Nov 30 2024 Valid 021200Z - 081200Z The overall synoptic pattern will change very little over the next several days (troughing east and ridging west), with additional cooler air masses expected to encompass much of the Midwest, Northeast, and Mid-Atlantic regions. This will lead to low fire-weather concerns across the entire CONUS through next week. One minor exception may be within the western and central FL Peninsula. This is where fuels, due to a lack of recent and expected rainfall, will continue to become more receptive to fire start and spread. This may especially be true Day 4/Tuesday, as a surface high progresses southward over TN and the pressure gradient increases across the South. However, confidence in critical wind speeds is far too low to introduce any probabilities in the extended forecast at this time. ..Barnes.. 11/30/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0139 PM CST Sat Nov 30 2024 Valid 302000Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected through tonight. ...20z Update... No forecast changes are needed. Thunderstorm potential remains very limited across the country. Occasional flashes have been noted within a heavy snow band in the vicinity of Watertown, NY, but coverage through 12z will remain too limited to warrant highlights. See the previous discussion for additional details. ..Moore.. 11/30/2024 .PREV DISCUSSION... /ISSUED 1018 AM CST Sat Nov 30 2024/ ...Synopsis and Discussion... Large-scale cyclonic flow aloft will continue over the eastern CONUS today. With dry and/or stable conditions persisting over land, thunderstorm potential is expected to remain very low through the period. One possible exception will be with snow bands occurring in western NY off Lakes Erie and Ontario. But, any lightning flashes should remain quite sparse/isolated due to very limited instability.

SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0122 PM CST Sat Nov 30 2024 Valid 021200Z - 031200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms will be possible on Monday across south Texas. Severe storms are not expected. ...Synopsis... An expansive mid/upper-level trough over the eastern CONUS will move slowly eastward on Monday, while upstream midlevel height rises reinforce surface high pressure from the northern Plains into the Southeast. As a result, boundary-layer moisture will remain confined to the Gulf of Mexico, limiting thunderstorm potential across much of the CONUS. The one exception will be over south TX, where a weak frontal wave interacting with sufficient boundary-layer moisture will promote scattered showers with isolated/embedded lightning potential. Any stronger storms should remain offshore, where instability will be greater. ..Weinman.. 11/30/2024 Read more
