AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
217 AM PDT WED MAY 2 2012

.SHORT TERM...
ANOTHER WEAK SHORTWAVE IS PROGGED TO MOVE THROUGH THE REGION TODAY
BRINGING  BREEZY AFTERNOON WINDS SIMILAR TO TUESDAY AFTERNOON.
INCREASING MOISTURE TONIGHT WILL ALLOW FOR IMPROVED OVERNIGHT
RECOVERIES TONIGHT INTO THURSDAY. BY THURSDAY INTO FRIDAY A MUCH
STRONGER SHORTWAVE WILL MOVE THROUGH THE REGION BRINGING INCREASED
CHANCES FOR SHOWERS AND STRONGER WIND GUSTS.

WIND GUSTS BETWEEN 30 TO 35 MPH ARE EXPECTED THIS AFTERNOON AS A
WEAK WAVE PASSES THROUGH THE SIERRA AND WESTERN NEVADA. MID TO UPPER
LEVEL MOISTURE WILL BEGIN TO SWEEP INTO THE REGION TONIGHT AS A
STRONGER TROUGH ADVANCES TOWARDS THE PACIFIC NORTHWEST. INCREASING
MOISTURE OVERNIGHT INTO THURSDAY MORNING COMBINED WITH DYNAMICS AND
COOLING ALOFT WILL IMPROVE CHANCES FOR SHOWERS IN THE NORTHERN
SIERRA AND PORTIONS OF NORTHWEST NEVADA. ALTHOUGH THE BEST DYNAMICS
AND LIFT WILL REMAIN TO THE NORTH OVER OREGON, MODELS CONTINUE TO
INDICATE DECENT JET ENHANCEMENT ALONG WITH STEEPER UPPER LEVEL LAPSE
RATES WHICH WOULD ALLOW FOR AT LEAST SLIGHT CHANCES FOR THUNDER IN
THE AFTERNOON. SO DECIDED TO LEAVE IN THUNDERSTORMS THROUGH
NORTHERN LASSEN AND FAR NORTHERN WASHOE COUNTIES.

ANOTHER ISSUE WITH THE INCOMING TROUGH WILL BE FOR GUSTY WINDS ON
THURSDAY. WITH INCREASING 700 MB FLOW BETWEEN 30 TO 40 KNOTS AND AN
INCREASING PRESSURE AND THERMAL GRADIENT, WESTERN NV VALLEYS COULD
SEE WINDS UP TO 45 MPH WITH RIDGE GUSTS UP TO 70 MPH. LAKE WIND
ADVISORIES WILL BE NEEDED AS LAKE CONDITIONS WILL BE CHOPPY AT BOTH
LAKE TAHOE AND PYRAMID ON THURSDAY.

BY FRIDAY AN ADDITIONAL WAVE SWINGS DOWN THROUGH THE LONGWAVE TROUGH
REINFORCING SHOWERS, ESPECIALLY LAKE TAHOE AND NORTHWARD. ALTHOUGH
BEST MOISTURE REMAINS NORTH OF THE CA/OR BORDER, THERE DOES APPEAR
TO BE SOME LOW LEVEL INSTABILITY ASSOCIATED WITH A COLD FRONT
SWINGING SOUTH FRIDAY AFTERNOON THROUGH THE EVENING. SINCE UPPER
LEVEL LAPSE RATES ARE NOT STEEP ENOUGH TO PROMOTE DEEP CONVECTION
AND MODEL SOUNDINGS CONTINUE TO INDICATE A CAP IN THE MIDLEVELS,
DECIDED TO LEAVE OUT THUNDER FOR FRIDAY AFTERNOON. LINDAMAN

.LONG TERM...SATURDAY THROUGH TUESDAY...
MODELS IN A LITTLE BETTER AGREEMENT THIS MORNING WITH THE PATTERN
FOR THE WEEKEND AND EARLY NEXT WEEK. HOWEVER, THERE IS STILL QUITE A
BIT OF UNCERTAINTY WITH THE DETAILS AND WHERE THE CUT-OFF LOW SETS
UP. EC HAS CONTINUES ITS FLIP-FLOPPING TREND AND IS NOW THE WARMEST
AND DRIEST OF THE MODELS NEXT WEEK. GFS IS MORE CONSISTENT AS IS THE
GEM SO WILL LEAN A BIT CLOSER TO THEM FOR THE FORECAST. THEY PUT THE
UPPER LOW OVER UTAH WITH A COOL NORTH FLOW ACROSS THE AREA.

OVERALL MADE FEW CHANGES TO THE GOING FCST. TWEAKED SATURDAY CHC OF
PRECIP IN THE NORTH TO CONFINE IT MORE TO NEAR THE OREGON BORDER.
ALL MODELS SHOW THE WAVE WILL HAVE PASSED BY SAT AFTERNOON SO NOT
SURE IF WE WILL SEE ANYTHING AT ALL NOW. ALSO DRIED OUT SUNDAY AS
THE UPPER LOW IS JUST GETTING SET UP TO OUR EAST. ATMOSPHERE LOOKS A
BIT TOO STABLE FOR ANY SHOWERS NOW, BUT DID LEAVE IN THE FEW SHOWERS
WE HAD IN OVER WRN NV FOR MONDAY. INSTABILITY LOOKS SLIGHTLY BETTER
THEN WITH SOME COLDER AIR ALOFT DUE TO A WEAK SHORT WAVE ON THE
BACKSIDE OF THE LOW. DRY AND WARMER FOR TUESDAY AS THE LOW PULLS
AWAY AND MORE RIDGING BUILDS IN. OVERALL KEPT TEMPS NEAR NORMAL
THROUGH THE PERIOD WITH COOLEST SATURDAY AND SLOW WARMING INTO
TUESDAY. TEMPS EACH DAY SHOULD BE WITHIN 5 DEGREES OF AVERAGE.

.AVIATION...
VFR CONDITIONS THROUGH 12Z THURSDAY THEN SOME MVFR CIGS PSBL THU
AFTERNOON AHEAD OF A COLD FRONT. WINDS WILL CONTINUE TO BE SW TODAY
WITH GUSTS 25-30 KTS AT ALL TERMINALS FROM 20-02Z. EXPECT SOME WINDS
OVERNIGHT NR 10KTS WITH SOME MTN WAVE TURBULENCE AFT 06Z AS WIND
INCREASES ALOFT. STRONG WINDS EXPECT THU AHEAD OF COLD FRONT WITH
GUSTS TO 40 KTS PSBL. WALLMANN
