...Mogollon Rim...
Daytime heating and instability within a corridor of precipitable
water values of 0.50-0.75 inches will support isolated dry
thunderstorm development across the Mogollon Rim this afternoon.
Heavier precipitation cores in the lower desert areas in southern
Arizona (with PWATs of around one inch) will limit new ignition
potential to the Mogollon Rim corridor where dry fuels exist.

...Synopsis...
A mid-level wave will begin to traverse the northern periphery of
the western ridge today, bringing an increase in westerly flow
across the Cascades in central Washington and northern Oregon.
Elevated fire weather conditions will be likely across the Cascade
Gaps and into the Columbia Basin, where relative humidity reductions
around 20 percent will overlap winds sustained 10-15 mph (locally
higher). An Elevated was maintained with this outlook to support
potential for increased fire spread potential.

...Dry Thunderstorms...
A mix of wet/dry thunderstorms will be possible in Northern Arizona
today. Moisture banked across the Mogollon Rim becomes less with
northern extent, where PWs drop to around 0.25-0.50". Storm motions
will be around 10-20 mph, but coverage should allow multiple rounds
of storms. However, outside of heavier cores and where less coverage
is expected across the western rim, there could be a few instances
of dry lightning. Overall, the small coverage of this risk does not
warrant inclusion of an area at this time.
