NORTHEAST PACIFIC WILL MOVE INTO THE PACIFIC NORTHWEST AND BRITISH
COLUMBIA FRIDAY. THE SOUTHERN GREAT BASIN AND MOJAVE DESERT WILL
REMAIN UNDER A DRY SOUTHWEST FLOW THROUGH THE UPCOMING WEEKEND WITH
GUSTY SOUTHWEST WINDS DEVELOPING DURING THE AFTERNOON HOURS.
&&

.UPDATE...DRA SOUNDING STILL INCREDIBLY DRY WITH ONLY 0.08 PW.
MORNING INVERSION HAS BROKEN AND HIGHER MOMENTUM IS BEING MIXED TO
THE SURFACE TO PRODUCE GUSTY WINDS FROM THE SOUTH-SOUTHWEST MOST
LOCATIONS. GRADIENT WILL CONTINUE TO STRENGTHEN TOMORROW AND FRIDAY
AS SHORT WAVE APPROACHES THE WEST COAST. NO UPDATES PLANNED FOR NOW
BUT WE WILL LIKELY ISSUE A FIRE WEATHER WATCH FOR FRIDAY AFTERNOON
ACROSS MUCH OF THE FORECAST AREA.  -RUNK-

.PREV DISCUSSION...FROM 330 AM PDT...SKIES CLEAR ACROSS THE FORECAST
AREA THIS MORNING UNDER PREVAILING SOUTHWEST FLOW. THE SOUTHERN
GREAT BASIN AND MOJAVE DESERT WILL REMAIN UNDER A SOUTHWEST FLOW AS
AREA STUCK BETWEEN AN UNSEASONABLY STRONG TROUGH OVER THE NORTHEAST
PACIFIC AND RIDGE TO OUR SOUTH AND EAST. MODELS HAVE BEEN CONSISTENT
SHOWING SHORTWAVE TROUGH EJECTING INLAND INTO WASHINGTON/BRITISH
COLUMBIA FRIDAY. GRADIENTS TIGHTEN MAINLY ACROSS CENTRAL AND
NORTHERN NEVADA. 00Z MOS GUIDANCE INDICATES LITTLE CHANGE IN WIND
SPEEDS BETWEEN THURSDAY AND FRIDAY ACROSS FAR SOUTHERN
NEVADA/NORTHWEST ARIZONA. HOWEVER...AT ELY NAM GUIDANCE GOES FROM 12
KTS THURSDAY TO 19 KTS ON FRIDAY. IT APPEARS THE POTENTIAL STILL
EXISTS THAT CRITICAL FIRE WEATHER CONDITIONS WILL DEVELOP ACROSS
PARTS OF CENTRAL NYE AND LINCOLN COUNTIES FRIDAY AFTERNOON. WILL LET
THE DAY SHIFT MAKE THE FINAL DETERMINATION AFTER SEEING THE 12Z AND
18Z MODEL RUNS.

.LONG TERM...LITTLE CHANGE TO INHERITED GRIDS AS MODELS CONTINUE TO
INDICATE RIDGING ACROSS THE AREA DURING THE EXTENDED. TEMPERATURES
WILL RUN SEVERAL DEGREES ABOVE NORMAL WITH LITTLE DAY TO DAY

WE MAY SEE A SLIGHT INCREASE IN MOISTURE BY MIDWEEK AS THE HIGH

HIGHEST PW VALUES ONLY AROUND 1/2 TO 3/4 OF AN INCH ALONG THE
EXTREME SOUTHERN EDGE OF THE CWA.

IN CALIFORNIA...OTHERWISE CLEAR SKIES.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA: RELATIVELY LIGHT WINDS AND CLEAR SKIES WILL PERSIST
ACROSS THE AREA. SMOKE FROM FIRES IN THE TEHACHAPI MTNS AND NEAR
