NWS Storm Prediction Center Norman OK
1224 AM CDT Wed Jul 28 2021
Valid 281200Z - 291200Z
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
...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
