DISCUSSION
THE ATMOSPHERE IS SERVING A BREAK TODAY FROM ALL THE RECENT GUSTY
WINDS AHEAD OF THE NEXT SYSTEM THAT IS INBOUND FOR MONDAY.
TEMPERATURES ACROSS THE REGION WILL NUDGE SLIGHTLY LOWER THAN
YESTERDAY, WITH UPPER 70S TO LOW 80S ACROSS WESTERN NEVADA AND
SOME CHILLY 50S FOR SOME SIERRA COMMUNITIES TODAY. WINDS PICK UP
THIS AFTERNOON, BUT ONLY TO THE LEVEL OF OUR TYPICAL SUMMERTIME
AFTERNOON GUST SPEEDS.
MONDAY A NEW TROUGH WILL ARRIVE, CARRYING GUSTY WINDS AND SOME
MOISTURE ALONG WITH IT. WE EXPECT TO SEE GUSTY WINDS KICKING UP
CHOPPY LAKES AND SOME BLOWING DUST, SO TAKE CAUTION IF YOU HAVE
PLANS FOR TRAVEL OR LAKE RECREATION. A LAKE WIND ADVISORY HAS BEEN
POSTED FOR AREA LAKES FOR TOMORROW. GUSTS ALONG RIDGETOPS WILL
REACH UPWARDS OF 50 MPH, WITH GUSTS ACROSS THE LEESIDE VALLEYS
REACHING 35 MPH. ALTHOUGH, JET DYNAMICS SUGGESTS THERE COULD BE A
BIT OF DOWNSLOPING EFFECT ALONG THE RIDGES REALIZED TOMORROW, THE
WINDS DON'T SEEM TO MIX ALL THE WAY TO VALLEY FLOORS, WHICH WILL
LIMIT THE WIND SPEEDS. NEVERTHELESS, IT WILL BE A BREEZY DAY FOR
MOST OF THE AREA.
AS FOR MOISTURE, PWAT SAMPLING OF SOUNDINGS ALONG THE OREGON
BORDER REVEAL READINGS OF 0.7-0.8 INCHES OF PRECIPITABLE WATER
AVAILABLE. SOUNDS PRETTY IMPRESSIVE FOR THIS AREA, BUT THE LOW-
LEVEL DRY AIR THAT HAS BEEN IN PLACE WOULD NEED TO BE SATURATED
TO SEE THAT AMOUNT OF WATER TRANSLATE TO ACCUMULATIONS AT THE
SURFACE. EVEN MORE IMPRESSIVE IS THE SIGNIFICANT DECREASE IN POPS,
EARLIER ADVERTISED AS 20-50%, BUT NOW GUIDANCE IS SHOWING 10-30%.
THE EXPECTATION IS THAT THE LOWER LEVELS WILL SEE AN INCREASE IN
RELATIVE HUMIDITY, BUT THE SHOWERS IN THE SKY MAY NOT HIT THE
GROUND. OWING TO THIS DRY AIR, THE BEST WE CAN SQUEEZE OUT OF THE
QPF WILL BE A FEW HUNDREDTHS TO A TRACE. THIS WILL ALSO AFFECT
FIRE WEATHER, IN THAT OUR RELATIVE HUMIDITY READINGS WILL INCREASE
INTO THE DAY ON MONDAY, ABATING FIRE WEATHER CONDITIONS INTO THE
EVENING HOURS. THAT SAID, THERE WILL BE A COUPLE HOURS OF ELEVATED
FIRE WEATHER CONDITIONS AS WINDS PICK UP OUT AHEAD OF THE ARRIVAL
OF THE MOISTURE. SEE DETAILS IN THE FIRE WEATHER SECTION BELOW.
THIS TROUGH WILL BE SHORT-LIVED OVER OUR REGION, SO BY TUESDAY WE
ALREADY SEE THE TROUGH EXITING TO OUR EAST. AND BY WEDNESDAY, THE
WARMING AND DRYING TREND WILL RETURN, AND REMAIN WITH US THROUGH
THE END OF THE WEEK. HRICH
AVIATION
* VFR CONDITIONS PRESENT TODAY ACROSS THE REGION, WITH BREEZY
WESTERLY WINDS PICKING UP GUSTS TO 20 KTS THIS AFTERNOON. WINDS
WILL INCREASE FOR MONDAY, WITH GUSTS TO 35 KTS POSSIBLE,
ESPECIALLY FOR KNFL AND KLOL. LLWS AND MOUNTAIN WAVE TURBULENCE
COULD DEVELOP IN POCKETS ACROSS THE SIERRA FOR MONDAY.
* SHOWERS ARE EXPECTED TO BE LIGHT ON MONDAY, WITH A 10% CHANCE
FOR SHOWERS FOR TAHOE BASIN TERMINALS KTRK AND KTVL, AND OVER
THE BASIN AND RANGE TERMINALS OF KLOL AND KNFL, CHANCES OF
5-10%. HRICH
FIRE WEATHER
ELEVATED FIRE WEATHER CONDITIONS WILL RETURN FOR A FEW HOURS
DURING THE AFTERNOON ON MONDAY, WHEN WINDS WILL BEGIN TO INCREASE
AHEAD OF AN INCOMING TROUGH. GUSTS TO 35 MPH WILL OVERLAP
RELATIVE HUMIDITIES RANGING 10-15% ACROSS POCKETS OF PERSHING,
CHURCHILL, LYON AND MONO COUNTIES FOR A COUPLE HOURS MONDAY
AFTERNOON. HRICH
