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. ..Bentley.. 07/28/2021 ...Please see www.spc.noaa.gov/fire for graphic product... Day 2 Fire Weather Outlook
