Added a small elevated area in the northern Central Valley in

California where gusty northerly winds are expected to reach 15 to

20 mph amid relative humidity of 12 to 18 percent. Otherwise, a

minor eastward expansion of the elevated area was made in West

Texas.

...Synopsis...

A large-scale trough positioned over the central CONUS will slowly

shift eastward throughout the forecast period. As this occurs,

ridging will take hold across much of the West. At the surface, a

cold front will continue sweeping across the central Plains, while

high pressure builds into the West.



...Southeast Arizona, southern New Mexico and Far West Texas...

Diurnally driven mixing of enhanced mid-level flow over the region

will allow strong winds to mix toward the surface, resulting in

sustained westerly winds of 20-30 mph while RH values fall into the

teens and single digits. Despite somewhat marginally receptive

fuels, dry conditions remain present across the region, supporting

the potential for critical fire-weather conditions during the

afternoon hours.



...Southern California...

Surface high pressure is expected to settle into the Great Basin

region, which will result the development of a surface pressure

gradient conducive for offshore winds. Sustained winds of 20-30 mph

can be expected, gusting to 35+ mph (particularly in terrain-favored

regions). Meanwhile RH values will fall into the single digits as

temperatures warm into the 80s F by afternoon. Despite these

conditions, fuels across the region are marginally receptive to

large-fire spread. Thus, elevated to locally critical fire-weather

conditions appear likely.
