SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1236 PM CST Thu Dec 28 2023 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track, and no changes are needed with this update. ..Weinman.. 12/28/2023 .PREV DISCUSSION... /ISSUED 1147 PM CST Wed Dec 27 2023/ ...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. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1124 AM CST Thu Dec 28 2023 Valid 291200Z - 301200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible along parts of the northern/central California coast on Friday. ...Synopsis and Discussion... An amplified upper-air pattern will exist on Friday, with a large upper trough and low over the eastern CONUS, and a ridge over the West. Another upper trough will affect the West Coast, bringing cooling aloft and increasing midlevel moisture. Weak elevated instability may support sporadic lightning flashes within the warm advection zone preceding the cold front from northern CA into western OR, with further destabilization taking place overnight as the cold front approaches the Coast. The greatest threat of isolated thunderstorms will be after 06Z, coincident with the coolest temperatures aloft. Forecast soundings show little if any threat of severe weather, given weakening shear beneath the upper trough axis. Elsewhere, high pressure extending into the Gulf of Mexico will maintain offshore winds, with no thunderstorms forecast across the remainder of the CONUS. ..Jewell.. 12/28/2023 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1035 AM CST Thu Dec 28 2023 Valid 281700Z - 291200Z ...NO CRITICAL AREAS... The forecast remains on track. For details, see the previous discussion below. ..Weinman.. 12/28/2023 .PREV DISCUSSION... /ISSUED 1146 PM CST Wed Dec 27 2023/ ...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. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
