Valid 161700Z - 171200Z

Elevated fire weather conditions are still expected across portions
of central Nevada with no changes needed for this update.
Temperatures are trending warmer and relative humidity lower from
yesterday, with dry, south-southwest flow expected to increase
through the day as a mid-level low remains over northern CA.
South-southwest winds of 15-20 mph and relative humidity falling to
around 15% will support an elevated fire concern threat for several
hours this afternoon.

...Synopsis...
A mid-level low sliding southward from the Pacific Northwest will
stall over northern California this afternoon, increasing deep-layer
southwesterly flow across the Great Basin. Hot and dry conditions
will continue across Texas and Oklahoma as high pressure expands
into the central U.S., though much lighter winds will limit broader
fire weather concerns.

...Central Nevada...
Elevated fire weather conditions are expected this afternoon where
dry and breezy south-southwesterly winds of 15-20 mph amid minimum
RH values of 10-15% overlap drying fuels. RH may decline to less
than 10% in some valleys, but marginal fuel receptiveness will mute
a more significant fire weather concern across the area.
