Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1056 AM CDT Fri Aug 05 2022

Valid 051700Z - 061200Z

An isolated dry thunderstorm risk area is introduced to portions of
northern CA into southern OR. Latest MRMS rainfall estimates suggest
ongoing convection is a mix of wet/dry thunderstorms with pockets of
wetting rainfall. Thunderstorm chances will persist into the
afternoon as a weak mid-level disturbance moves into the northern
Great Basin. Forecast soundings show inverted-V soundings with cloud
bases near 2.5-3 km and PWAT values near 0.8 to 1.0 inch. These
thermodynamic conditions are supportive of a mix of wet/dry
thunderstorms over a region with receptive fuels and a history of
recent fire starts. See the previous discussion below for additional
forecast concerns.

...Synopsis...
An upper-level shortwave trough evident on water vapor imagery this
morning over the Pacific Northwest is forecast to move eastward
across southern Canada today. An associated surface low over
Manitoba will deepen with a trailing surface trough/cold front
draped southward into the northern Plains. While the enhanced
surface pressure gradient across the region will lead to windy
pre-frontal and post-frontal conditions across portions of the
northern Plains, the overlap of strong winds with critical RH values
appears unlikely, limiting fire weather concerns.
