Area Forecast Discussion

.SYNOPSIS...High pressure will continue to build across the Great
Basin, bringing warming temperatures and quiet weather into the
upcoming weekend.


.SHORT TERM...Today through Friday. Satellite loop this morning is
showing some mid to high-clouds pushing east across the forecast
area. There are some weak echos in northeast Nevada but do not
anticipate much precipitation.

For today, an upper low will be east of the area across northern
Utah, while an upper ridge sites across the western United States.
Expect mainly quiet and sunny weather today with highs in the 70s
to possibly 80 degrees. Winds will be light, though occasional
afternoon breezes to 20 mph are possible. Look for a continuation
of quiet weather tonight with overnight lows in the 20s and 30s.

By tomorrow, look for the upper level ridge to continue building
into the forecast area. Skies will remain mostly sunny over the
region but high temperatures will warm into the upper 70s to mid
80s. Winds will continue to remain light.

.LONG TERM...Friday night through next Wednesday.
Good long term agreement amongst ensemble members, at least 
through early next week. Broad low amplitude ridge covers much of 
the western CONUS. A weak closed low west of the Baja California 
coast ejects toward the Four Corner states. Does not appear this 
will affect the benign weather pattern for northern and central 
Nevada. Afternoon highs will be in the 80s from Saturday through 

Tuesday and Wednesday marks a changing weather pattern, and model
spread exists. The operational GFS shows a relatively open wave 
busting across the Great Basin on Tuesday. Another scenario places
a closed low circulation off the California coast and eventually 
moving inland. Potential for showers exist for Tuesday and 
Wednesday with cooler temperatures. If nothing else, afternoons of
summer like temperatures are coming to an end.


.AVIATION...VFR prevails until further notice. Relatively calm
wind, although G20KTS are possible during the afternoon time


.FIRE WEATHER...Dry conditions will remain the rule through the
weekend as high pressure dominates the weather across the area.
Highs will remain above normal for this time of year with minimum
relative humidity in the single digits to teens. There could be
some breezes during the weekend, with Sunday possibly seeing
elevated fire weather conditions in the northern zones as an upper
level low pressure system moves into the Pacific Northwest. This
will need to be watched closely for possible wind/RH concerns.
