U.S. Day 1 Fire Weather Outlook

   ZCZC SPCFWDDY1 ALL
   FNUS21 KWNS 271523

   Day 1 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   1023 AM CDT Tue Oct 27 2026

   Valid 271700Z - 281200Z

   ...NO CRITICAL AREAS...

   No changes were made to the forecast as previously described. Recent
   widespread rainfall and cooler-than-normal daytime temperatures have
   limited the overall fire environment threat across the CONUS. In
   addition to westerly flow (sustained 15-25 mph surface winds) over
   WY and western SD, northeasterly flow (sustained 10-15 mph surface
   winds) over much of the Florida Peninsula is worth mentioning.
   However, forecast near-normal temperatures amid afternoon RHs
   unlikely to fall below 50% will similarly preclude a significant
   fire weather risk there.

   .PREV DISCUSSION... /ISSUED 1253 AM CDT Tue Oct 27 2026/

   ...Synopsis...
   Fire weather concerns remain low across the CONUS today. A robust
   60-70 kt mid-level jet on the southern periphery of an upper trough
   will overspread WY into the northern Plains. Surface lee troughing
   across the northern High Plains and the presence of a strong
   mid-level jet will support downslope enhanced westerly winds of
   20-30 mph and minimum RH of 20% across portions of central/eastern
   WY into western SD. However, cooler daytime high temperatures in the
   50s to low 60s amid a marginal fuel environment will limit a broader
   fire weather threat.
      

U.S. Day 2 Fire Weather Outlook

   Day 2 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0155 PM CDT Tue Oct 27 2026

   Valid 281200Z - 291200Z

   ...NO CRITICAL AREAS...

   The previous forecast remains on track as described. A lack of
   strong wind where fuels are available to burn, in particular over
   the southern CONUS, will preclude any significant fire weather
   threat on Day 2/Wednesday.

   ..Stearns.. 10/27/2026

   .PREV DISCUSSION... /ISSUED 1255 AM CDT Tue Oct 27 2026/

   ...Synopsis...
   Reduced fire weather concerns are expected across the CONUS on Day
   2/Wednesday. Low-amplitude upper troughing will continue across the
   northern CONUS while upper ridging begins to weaken over the
   Southeast. High temperatures in the 80s and minimum RH values of
   25-30% will overlap drought-stressed fuels in the lower MS River
   Valley. However, lighter prevailing winds should limit a fire
   weather threat over this region.


U.S. Day 3-8 Fire Weather Outlook


   ZCZC SPCFWDD38 ALL
   FNUS28 KWNS 262125

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0425 PM CDT Mon Oct 26 2026

   Valid 281200Z - 031200Z

   ...Synopsis...
   An active weather pattern will persist across the Northwest, Plains
   and the Upper Midwest as a troughing regime contributes to cloud
   cover, precipitation and cooler temperatures reducing overall fire
   weather concerns through late this week. More amplified troughing
   emerges across the western U.S. over the weekend promoting
   increasing southwest flow aloft over the region. This could invite a
   plume of deeper subtropical moisture into the West, bringing
   additional precipitation across much of Intermountain West this
   weekend and early next week.

   A broad ridging pattern over the eastern U.S. should be maintained
   through Day 5/Friday supporting above normal temperatures and mainly
   dry conditions for much of the region. Fuels across the lower MS
   River Basin into the Deep South remain quite receptive. Ridging
   aloft and surface high pressure across the Appalachians will allow
   areas of critically low RH to emerge each afternoon through Day
   5/Friday amid the dry fuelscape. However, light surface winds will
   attenuate the fire weather threat over this region. Precipitation
   chances increase for the lower MS River Valley and Southeast over
   the weekend as the surface high over the Appalachians repositions
   over the Northeastern U.S. This will aid in northward moisture
   transport from the Gulf as a series of short wave troughs within a
   more pronounced subtropical jet impacts the region.
