SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1147 PM CST Wed Dec 27 2023 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... ...Synopsis... Some moderately breezy conditions are possible across portions of the Mississippi Valley into the Southeast on Friday as the mid-level trough shifts eastward. However, temperatures will be cool and fuels remain moist across these areas. Therefore, fire weather concerns will be minimal. Elsewhere, moist fuels are present across most of the CONUS which precludes any fire-weather concerns. ..Bentley.. 12/28/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1146 PM CST Wed Dec 27 2023 Valid 281200Z - 291200Z ...NO CRITICAL AREAS... ...Synopsis... Wetting rain/snow has occurred across a large portion of the CONUS in the last week. This has added additional moisture to already moist fuels. In addition, a cool pattern has infiltrated the CONUS. The combination of these factors support minimal fire-weather threat and therefore, no fire-weather areas are warranted. ..Bentley.. 12/28/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0650 PM CST Wed Dec 27 2023 Valid 280100Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...01Z Update... Even with instability forecast to remain rather weak, isolated lighting flashes will remain possible within a band of precipitation that will move eastward across the coastal Mid-Atlantic tonight. Occasional thunderstorms may also occur late tonight into early Thursday morning across parts of the FL Keys as modest low-level moisture return occurs in tandem with a low-amplitude shortwave trough moving northeastward across the Gulf of Mexico. Isolated convection capable of producing lightning flashes will also remain possible this evening over parts of CA and coastal WA/OR. Across all these regions, weak instability will preclude a threat for organized severe thunderstorms. ..Gleason.. 12/28/2023 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0322 PM CST Wed Dec 27 2023 Valid 291200Z - 041200Z The potential for critical fire-weather conditions appears low through the extended forecast period. On D3/Friday, a midlevel low will devolve into a large-scale trough over the eastern CONUS, while a related swath of strong deep-layer west-southwesterly flow overspreads the Southeast. This may promote locally breezy conditions across the region, though cool surface temperatures/marginal RH reductions and recent rainfall should limit most fire-weather concerns. Thereafter, a large-scale trough over the West will deamplify into a shortwave trough and cross the southern Rockies on D5/Sunday. As this occurs, an accompanying belt of strong westerly downslope flow will promote lee troughing over the southern High Plains, with dry/breezy conditions possible across portions of West TX. With that said, marginal fuels across the area should mitigate the fire-weather threat. ..Weinman.. 12/27/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0132 PM CST Wed Dec 27 2023 Valid 272000Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States through tonight. Only minor changes to the Carolinas thunder line as drier air moves in from the southwest. ..Jewell.. 12/27/2023 .PREV DISCUSSION... /ISSUED 1021 AM CST Wed Dec 27 2023/ ...Mid Atlantic Region... A large upper low remains dominant over the central/eastern CONUS, with a deep warm-conveyor regime over the Mid-Atlantic region. Scattered showers and isolated thunderstorms will be possible this afternoon from eastern NC northward across the Chesapeake Bay area into PA/NJ. A cool and marginally unstable boundary-layer will preclude a risk of severe storms. ...FL Keys... A southern-stream shortwave trough over northern Mexico will track across the Gulf of Mexico and begin affecting the FL Keys after midnight. This may result in isolated thunderstorms over the lower Keys or nearby shelf waters. ...West Coast... A few lightning flashes are possible this afternoon and evening over coastal WA/OR and parts of northern/central CA as a cold front moves ashore. Read more
