   Day 1 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   1224 AM CDT Wed Jul 28 2021

   Valid 281200Z - 291200Z

   ...Synopsis...
   The pattern on Wednesday will remain mostly stagnant with an
   upper-level ridge centered across eastern Colorado. Monsoon moisture
   continues to advect northward around the westward edge of this
   ridge. At the surface, a weak area of low pressure will move through
   the Dakotas with a trailing cold front extending back into eastern
   Montana and eastern Wyoming.

   ...IsoDryT - Northwest and northern Rockies...
   Cloud cover which has limited instability the past few days will
   move northward into Canada leaving mostly clear skies across the
   Northwest. This should allow significant heating and instability to
   develop by the afternoon. Other than a weak shortwave forecast to
   move through western Oregon, forcing is forecast to be nebulous.
   However, at least isolated storm development is expected, especially
   over the higher terrain in central Idaho and western Montana. PWAT
   values are on the higher side in the region (0.8 to 1.0 inches), but
   fuels remain extremely dry with ERC values above the 95th
   percentile. 

   ...Portions of the northern Plains...
   A cold front is forecast to move southward across the northern
   Plains this afternoon. In its wake, dry and breezy conditions are
   forecast with winds of 15 to 20 mph and RH values around 20 to 30
   percent. Fuels are very dry in this region with near-record ERC
   values in many spots. Therefore, elevated fire weather conditions
   are expected.
