SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0114 PM CST Thu Jan 16 2025 Valid 171200Z - 181200Z ...NO CRITICAL AREAS... ...19z Update... No changes, see the prior outlook for more info. ..Lyons.. 01/16/2025 .PREV DISCUSSION... /ISSUED 0145 AM CST Thu Jan 16 2025/ ...Synopsis... A mid-level trough will rapidly eject into the Lower MS Valley from the southern Rockies area tomorrow (Friday), resulting in surface low development over the southern Plains. Dry downslope flow, followed by a surface cold front, will foster 20-30 mph sustained westerly surface winds and RH down to 20 percent across the southern High Plains Friday afternoon. While these conditions typically support at least Elevated highlights, the lack of receptive fuels suggests that any wildfire-spread potential should remain localized at best. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1121 AM CST Thu Jan 16 2025 Valid 171200Z - 181200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across the Lower Mississippi and Tennessee Valleys, and central Gulf Coast region Friday night into early Saturday morning. ...Synopsis... A short-wave trough digging southeastward out of western Canada across the north-central U.S. will partially phase with a second trough moving out of the Desert Southwest across the southern Plains, resulting in evolution of large-scale troughing across the CONUS. By Saturday morning, highly amplified cyclonic flow is forecast to encompass nearly the entirety of North America. At the surface, a deep cyclone associated with the upper troughing, initially over western Ontario, is forecast to occlude as it rotates northeastward across the James Bay area. A trailing cold front will sweep across the Plains/Upper Great Lakes/Midwest, and should reach a position from Lower Michigan southwestward to the Lower Mississippi Valley by 18/12Z (Saturday morning). ...Lower Mississippi Valley/central Gulf Coast area... As a cold front advances southeastward toward, and eventually into, the lower Mississippi Valley area, low-level warm advection atop a still cool/stable warm-sector boundary layer will lead to development of elevated convection, mainly during the second half of the period. As convection evolves, and low-level theta-e advection supports continued/modest elevated destabilization, a few thunderstorms will likely develop. While strengthening flow aloft during the period will result in shear that would otherwise support organized storms, the combination of a boundary layer not conducive for surface-based storms, and weak instability aloft, suggests that severe threat should remain no more than minimal at best across this region. ..Goss.. 01/16/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1019 AM CST Thu Jan 16 2025 Valid 161700Z - 171200Z ...Morning Update... Offshore flow over southern CA is expected to gradually diminish today as pressure gradients weaken and onshore flow returns. While winds will be weaker, terrain-enhanced gusts may still reach 10-15 mph with RH less than 10% possible across the interior valleys and higher terrain of southern CA. Thus, some localized fire-weather conditions are possible through this afternoon. See the prior discussion. ..Lyons.. 01/16/2025 .PREV DISCUSSION... /ISSUED 0145 AM CST Thu Jan 16 2025/ ...Synopsis... A mid-level trough will impinge on the Baja Peninsula today, supporting a weakening of the surface pressure gradient across California during through the afternoon. During the first few hours of the morning though, residual offshore flow may be strong enough to foster localized wildfire-spread potential, with Elevated highlights introduced. Farther east, a mid-level trough ejecting into the Atlantic will encourage surface lee troughing over the eastern U.S. During the afternoon, sustained west-southwesterly surface winds approaching the 10-15 mph range amid 30-40 percent RH may overspread Alabama into the Carolinas. Elevated highlights have been withheld given marginally dry fuels and relatively weak surface wind fields. However, localized wildfire-spread potential may exist by around afternoon peak heating. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
