WARNING WITH SFC GUSTS OVER 30 MPH WED AFTN. CYLKE

.PREVIOUS SHORT TERM...
TROUGHS OVER CALIFORNIA AND OFF THE OREGON COAST WILL PHASE TODAY
AND PASS OVER WESTERN NEVADA...WITH SOME GUSTY WINDS ALONG THE
SIERRA FRONT AND ISOLATED THUNDERSTORMS ACROSS THE FAR NORTHERN AND
FAR SOUTHERN AREAS THIS AFTERNOON.  A MUCH STRONGER SHORT WAVE WILL
REACH THE AREA ON WEDNESDAY...AND PRODUCE WIND GUSTS NEAR 30 MPH
OVER MUCH OF THE AREA.  DRY AIR WILL ALSO BE IN PLACE AND THIS
RAISES A FIRE WEATHER CONCERN.  THE CURRENT HIGHLIGHT IN THE FIRE
FORECAST FOR GUSTY WINDS HANDLES THE SITUATION WELL.  HOWEVER A
15-20 DEGREE THERMAL GRADIENT DEVELOPS BETWEEN THE SIERRA AND THE
LOVELOCK-FALLON AREA.  THIS COULD BUMP WIND UP A TAD HIGHER THAN
WHAT THE MODELS CURRENTLY SHOW...AS THE JET PASSES OVERHEAD.  THE
SOUTHWEST FLOW REMAINS IN PLACE THROUGH THURSDAY WITH DRY AND SUNNY
CONDITIONS.  THE FLOW ALOFT STARTS TO DECREASE THURSDAY NIGHT AS
ANOTHER TROUGH BEGINS TO DEVELOP OFF THE CALIFORNIA COAST.  BRONG

.LONG TERM...FRIDAY THROUGH MONDAY...
AGREEMENT BETWEEN MEDIUM RANGE MODELS IS NOT AS GOOD AS IT HAS BEEN
OVER THE PAST FEW MODEL RUNS. THE GFS HAS SHOWN BETTER RUN TO RUN
CONSISTENCY AND FOR NOW WILL USED AS THE BASIS FOR THIS FORECAST.
THE ECMWF HAS DONE AWAY WITH THE EASTERN PACIFIC TROUGH OVER THE
WEEKEND AND STRENGTHENED THE RIDGE OVER THE SOUTHWESTERN CONUS. THE
PREFERRED GFS CONTINUES THE THEME OF A BAGGY TROUGH ALONG THE WEST
COAST THROUGH THE PERIOD WITH WEAK VORTICITY FEATURES MOVING THROUGH
THE TROUGH AND OVER THE FORECAST AREA. THERE REMAINS ENOUGH OF A
SOUTHWEST FLOW TO KEEP MOST OF THE CWA DRY ALTHOUGH THE USUAL
MONO/MINERAL COUNTY ZONES COULD SEE AN AFTERNOON THUNDERSTORM OR TWO
EACH DAY. HAVE ALSO ADDED AFTERNOON AND EVENING THUNDERSTORMS TO FAR
NORTHERN WASHOE COUNTY FOR SUNDAY AND MONDAY AS THE TROUGH EDGES
EAST AND PROVIDES SOME CONVERGENCE NEAR THE OREGON BORDER. LITTLE
DAY TO DAY CHANGE IN TEMPERATURES DURING THE PERIOD WITH HIGHS NEAR
SEASONAL NORMALS. RC
