Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0153 AM CDT Fri Sep 06 2024

Valid 071200Z - 081200Z

...Synopsis...
As the weak Pacific trough continues inland, additional mid-level
moisture will advect onshore over portions of the northern Sierra
and Cascades through the weekend. The upper ridge will continue to
slowly weaken, allowing for isolated thunderstorms over the
Northwest. Thunderstorms are likely across portions of the Cascades
in OR and southern WA, across the Sierra, and into portions of
southern CA. Hot and well-mixed boundary-layer profiles will likely
support low precipitation efficiency, especially with storm motions
greater than 20 kt. Confidence in dry thunderstorm coverage is
greatest across portions of the central Cascades, though drier
storms will also be possible, albeit less certain, across the
northern Sierra and parts of southern CA. Given the risk for
lightning atop dry fuels, an IsoDryT area has been added where storm
coverage and confidence in lightning atop dry fuels is highest.

In addition to the risk for lightning, increasingly strong
southwesterly flow aloft is expected to support gusty downslope
winds over parts of northern CA and northwest NV. Gusty winds of
15-20 mph in the lee of the Sierra are likely to overlap with
afternoon RH values below 20%. With receptive fuels and at least a
few hours of dry and breezy conditions possible, elevated
fire-weather conditions are likely.
