.SYNOPSIS...SCATTERED SHOWERS AND THUNDERSTORMS WILL BE CONFINED
TO MAINLY WHITE PINE AND NYE COUNTIES THROUGH THIS EVENING. THE
REMAINDER OF NORTHERN NEVADA WILL REMAIN DRY. HOT AFTERNOON
TEMPERATURES WILL CONTINUE ON TUESDAY. AN APPROACHING COLD FRONT
WILL BRING STRONG SOUTHWEST WINDS WEDNESDAY AND NOTICEABLY COOLER
TEMPERATURES THURSDAY.

&&

.SHORT TERM...TONIGHT THROUGH WEDNESDAY. MOISTURE AND INSTABILITY
MUCH MORE CONFINED TODAY AS EXPECTED...CONFINED TO NYE/WHITE
PINE/FAR SE ELKO COUNTIES. SCATTERED THUNDERSTORM COVERAGE WILL
CONTINUE IN THESE ZONES INTO THE EVENING HOURS. WITH PRECIPITABLE
WATER VALUES OF 0.80-1.00 INCH...EXPECT MOST STORMS TO BE WET.
IN FACT...LOCALLY HEAVY RAINFALL IS EXPECTED IN MAINLY WHITE PINE
COUNTY INTO THIS EVENING. ELSEWHERE...DRY AIR HAS INVADED FOR
CLEAR SKIES OVERNIGHT.

TUESDAY...SW FLOW BEGINS TO INCREASE ACROSS NEVADA AS STRONG
TROUGH DIGS DOWN THE PACIFIC NORTHWEST COAST. THICKNESSES CHANGE
LITTLE ON TUESDAY...SO EXPECT MORE ABOVE NORMAL MAX TEMPS...IN THE
LOWER 90S FOR MOST VALLEYS. INCREASING SW FLOW WILL SCOUR ANY
DECENT MOISTURE WELL EAST OF US INTO UTAH. HOWEVER MODELS DO HANG
ONTO SOME VERY MARGINAL PW'S OF 0.50-0.60 AND MARGINAL INSTABILITY
NEAR THE UTAH BORDER...SO KEPT SOME ISOLATED THUNDERSTORMS
MENTIONED IN THIS AREA AS SUGGESTED BY 12/18Z NAM.

WEDNESDAY...FIRST STRONG TROUGH OF THE SEASON DIGS INTO THE
PACIFIC NORTHWEST...WITH THE TROUGH AXIS AND LOWERING HEIGHTS
ENTERING NW NEVADA BY WEDNESDAY EVENING. WITH 700 MB WINDS
INCREASING TO 20-30 KTS...SW WINDS WILL INCREASE TO 15-30 MPH BY
AFTERNOON WITH HIGHER GUSTS LIKELY. THICKNESSES DROP SIGNIFICANTLY
ACROSS NORTHERN NEVADA BY AFTERNOON RESULTING IN A NOTICEABLE 5-8
DEGREES OF COOLING...MUCH CLOSER TO NORMAL FOR THE LAST DAY OF
AUGUST. THIS TROUGH WILL HAVE ONLY VERY PALTRY MOISTURE TO WORK
WITH...PW'S PERHAPS NEAR 0.50 INCH ALONG THE OREGON/IDAHO BORDER
AND NOTHING MORE. WITH THE STRONG LIFT EXPECTED AHEAD OF THE
TROUGH...ADDED ISOLATED THUNDERSTORMS TO THE NORTHERN ZONES
WEDNESDAY AFTERNOON. CONVECTION THAT DOES FORM WEDNESDAY WOULD
LIKELY BE DRY...BUT NAM/GFS BOTH TRY TO GENERATE CONVECTION
IN/NEAR HUMBOLDT COUNTY WEDNESDAY AFTERNOON. BT

.LONG TERM...WEDNESDAY NIGHT THROUGH NEXT MONDAY. GENERALLY QUIET
FOR THE LONG TERM AS A DRY AIRMASS DOMINATES THE GREAT BASIN. THUS
NO MENTIONABLE POPS IN THE GRIDS THROUGH NEXT WEEKEND. A COLDER
AIRMASS OVER THE CWA OVERNIGHT WEDNESDAY INTO THURSDAY MORNING WITH
LOW TEMPERATURES IN THE 30S HIGHER VALLEYS WITH CERTAIN HIGHER
VALLEYS IN THE NORTH POSSIBLE GOING TO THE UPPER 20S BRIEFLY AROUND

&&

.FIRE WEATHER...CONVECTION CONFINED TO MAINLY FWZ 455 AND 457
THROUGH THIS EVENING...ALTHOUGH ISOLATED THUNDERSTORMS ARE
POSSIBLE IN SE FWZ 470 /SE ELKO COUNTY/. CONVECTION EXPECTED TO BE
LARGELY WET IN WHITE PINE/NYE COUNTIES...MAY SEE A FEW DRY STORMS
ON THE NORTHERN FRINGE OF THE MOISTURE PLUME ACROSS SE ELKO
COUNTY. MOISTURE EXPECTED TO REMAIN SUFFICIENT FOR ISOLATED
CONVECTION ACROSS MAINLY FWZ 455/470 THROUGH TUESDAY. MAJORITY OF
MOISTURE WILL BE CONFINED TO UTAH...SO ANY STORMS IN EASTERN
ELKO/WHITE PINE COUNTIES TUESDAY AFTERNOON/EVENING WILL TEND TO BE
DRY.

WILL MAINTAIN FIRE WEATHER WATCH FOR WEDNESDAY AFTERNOON AND
EVENING...FOR ALL FWZ EXCEPT 467. IN NW NEVADA...LESS MIXING
EXPECTED TO RESULT IN KEEPING WINDS BELOW CRITICAL CRITERIA
WEDNESDAY. TEMPERATURES WILL COOL SEVERAL DEGREES WEDNESDAY AS
COLD FRONT APPROACHES...BUT AIRMASS WILL REMAIN DRY /MIN RH
7-12%/. SW WINDS WILL INCREASE MARKEDLY AHEAD OF THE COLD FRONT
WEDNESDAY...AVERAGING 15-25 MPH WITH GUSTS NEAR 30-35 MPH LIKELY.
THEREFORE CONTINUE TO EXPECT WIND/RH RED FLAG CRITERIA WILL BE MET
ACROSS MOST OF THE FIRE DISTRICT WEDNESDAY...AND FIRE WEATHER
WATCH REMAINS VALID. IN ADDITION...ADDED ISOLATED THUNDERSTORMS TO
THE NORTHERN FWZ WEDNESDAY...FOR FWZ 467/468/469/470. STRONG LIFT
AHEAD OF APPROACHING TROUGH LIKELY TO RESULT IN AT LEAST CUMULUS
BUILDUPS ACROSS THE HIGHER TERRAIN OF NORTHERN NEVADA WEDNESDAY
