.SHORT TERM...
UPPER LOW JUST OFF THE PAC NW COAST EARLY THIS MORNING WILL MOVE
EAST INTO THE NRN ROCKIES BY MONDAY. THE MAIN IMPACT OF THIS LOW ON
OUR CWA WILL BE THE WINDS TODAY. THE GRADIENT IS ALREADY SHOWING
SIGNS OF TIGHTENING SOUTH OF THE LOW PER GRADIENTS BETWEEN RNO-SAC
AND RNO-MFR. WINDS ALONG THE SIERRA CREST ARE INCREASING AND
HUMIDITIES ARE DROPPING. SFC GRADIENTS WILL CONTINUE TO TIGHTEN
THROUGH THIS AFTERNOON ALONG WITH INCREASING 700 MB WINDS TO NEAR
20-25 KTS NORTH OF INTERSTATE 80. THEREFORE WINDS WILL BE STRONGER
THAN IN PREVIOUS DAYS...WITH GUSTS NEAR OR JUST ABOVE 30 MPH
EXPECTED MAINLY NORTH OF HIGHWAY 50. THE NEXT ISSUE WILL BE THE
HUMIDITIES. THE MODELS STILL INDICATE A DRY SLOT MOVING IN BY THIS
AFTERNOON WHICH...ALONG WITH INCREASING DOWNSLOPE WINDS...WILL HELP
TO DRY THE LOWER ELEVATIONS EVEN FURTHER. THE MID SHIFT WILL TAKE A
LOOK AT THE MORNING SOUNDING AND MONITOR FOR POSSIBLE RED FLAG EVENT
IN THE RENO/CARSON CITY AREAS LATE THIS AFTERNOON INTO THIS EVENING.
OTHERWISE LAKE WIND ADVISORIES WILL REMAIN FOR TODAY FOR ALL BUT
MONO AND MINERAL COUNTIES...WHERE WINDS WILL BE SLIGHTLY LOWER.
CONDITIONS WILL REMAIN DRY THROUGH MEMORIAL DAY. SOME CUMULUS IS
LIKELY IN MONO/MINERAL COUNTY THIS AFTERNOON DUE TO WEAK INSTABILITY
AND CONVERGENCE IN FAVORABLE ZONE...HOWEVER DO NOT EXPECT CONVECTION
THROUGH MONDAY. AS LOW PASSES BY TO THE NORTH THE FLOW TURNS MORE
NORTHERLY BETWEEN EXITING LOW AND HIGH PRESSURE MOVING INTO THE
AREA. THIS WILL LOWER TEMPERATURES ONLY A COUPLE OF DEGREES ON
MONDAY...BUT STILL REMAIN IN THE MID 80S IN WRN NV VALLEYS AND IN
THE LOW TO MID 70S IN THE SIERRA. THE RIDGE AND THERMAL TROUGH MOVES
OVER THE SIERRA ON TUESDAY WITH CUMULUS BUILDUPS LIKELY OVER THE
SIERRA AND FAR WRN NV. RIGHT NOW THINK CONVECTION CHANCES ARE TOO
LOW ON TUESDAY TO INTRODUCE POPS YET...BUT CHANCES ARE MUCH BETTER
BY MID WEEK. TEMPERATURES WILL REMAIN 10-12 DEGREES ABOVE NORMAL
THROUGH TUESDAY...WITH FURTHER WARMING EXPECTED BY MID WEEK. BENINATO

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
STRONG RIDGE WILL REMAIN IN PLACE THROUGH THE PERIOD...LEAVING THE
AREA WITH TEMPERATURES 10-15 DEGREES ABOVE NORMAL.  HIGHS IN THE
NEVADA VALLEYS SHOULD REACH THE LOW TO MID 90S...PERHAPS HIGHER THAN
THE CURRENT FORECAST AFTER SEVERAL DAYS OF INTENSE HEATING AND
MINIMAL COOLING AT NIGHT.  LOWS IN THE WARMEST VALLEYS SHOULD
REMAIN ABOVE 55 FOR SEVERAL NIGHTS.

MODELS TRY TO PUSH SOME CLOSED LOWS TOWARD THE COAST AND THIS WOULD
HELP INSTABILITY BUILD...ALONG WITH THE WELL ABOVE NORMAL
TEMPERATURES.  THUNDERSTORM FORECASTS LOOK GOOD FOR THE SIERRA AND
PORTIONS OF WESTERN NEVADA.  BRONG

&&

.AVIATION...
VFR CONDITIONS WITH HIGH PRESSURE BUILDING OVER THE AREA EARLY NEXT
WEEK.  LOW WILL TRACK NORTH OF THE AREA TODAY AND PRODUCE 25-30KT
GUSTS ALONG THE EAST SLOPES OF THE SIERRA NORTH OF US-50 BETWEEN 21Z
AND 03Z.  NO OTHER CONCERNS UNTIL MID WEEK WHEN THUNDERSTORMS SHOULD
START TO DEVELOP ALONG THE SIERRA.  BRONG
