AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
230 AM PDT THU JUL 3 2014

.SYNOPSIS...
WEAKENING HIGH PRESSURE WILL RESULT IN BREEZY CONDITIONS EACH
AFTERNOON AND EVENING AS WELL AS COOLING DAYTIME HIGHS TO NEAR
NORMAL FOR THE HOLIDAY WEEKEND. HIGH PRESSURE WILL STRENGTHEN NEXT
WEEK BRINGING A WARMING TREND AND INCREASING CHANCES FOR
THUNDERSTORMS.

&&

.SHORT TERM...
DRY SOUTHWEST FLOW PERSISTS TODAY LIMITING CONVECTION ACROSS MUCH OF
THE EASTERN SIERRA AND WESTERN NEVADA. SLIGHT CHANCES OF
THUNDERSTORMS AND SHOWERS WILL BE POSSIBLE TODAY IN THE LASSEN
CONVERGENCE ZONE AS WINDS INCREASE LATER THIS AFTERNOON/EVENING.

OTHERWISE, A LARGE SCALE TROUGH DROPPING INTO BRITISH COLUMBIA WILL
BEGIN TO FLATTEN THE FOUR CORNERS HIGH ACROSS THE WEST. AS THE RIDGE
WEAKENS ACROSS THE REGION, LOWERING HEIGHTS WILL RESULT IN A COOLING
TREND TODAY, FRIDAY AND SATURDAY. TEMPERATURES WILL REMAIN NEAR
NORMAL FOR EARLY JULY, WHICH MEANS IT WILL STILL BE IN THE HIGH
90S IN WESTERN NEVADA VALLEYS AND IN THE 80S FOR THE SIERRA.

TYPICAL AFTERNOON/EVENING ZEPHYR WINDS ARE EXPECTED EACH DAY WITH
GUSTS TO 25 MPH (LOCALLY 25-30 MPH). WEST WINDS MAY BE ENHANCED
ON FRIDAY AS SURFACE THERMAL/PRESSURE GRADIENTS STRENGTHEN IN
RESPONSE TO THE PROXIMITY OF THE TROUGH OFF THE PACIFIC NORTHWEST
COAST. WIND GUSTS ON THE FOURTH OF JULY WILL BE IN THE 25-30 MPH
RANGE, ESPECIALLY FOR AREAS NORTH OF INTERSTATE 80. WINDS APPEAR
TO REMAIN BELOW RED FLAG OR LAKE WIND THRESHOLDS, BUT IF THE TROUGH
DROPS FURTHER SOUTH THEN FUTURE SHIFTS WILL NEED TO REEVALUATE THE
THREAT. ELW

.LONG TERM...SUNDAY THROUGH WEDNESDAY...
MINIMAL CHANGE TO THE LONG TERM FORECAST THIS MORNING.

A LARGE-SCALE UPPER RIDGE WILL RESIDE OVER EASTERN CALIFORNIA AND
WESTERN NEVADA THROUGH THE FIRST HALF OF NEXT WEEK. THIS IS EXPECTED
TO BRING ABOVE TO WELL ABOVE AVERAGE AFTERNOON TEMPERATURES,
ALTHOUGH AFTER SUNDAY OR MONDAY HIGHS COULD BE AFFECTED
SIGNIFICANTLY DOWNWARD BY CONVECTIVE DEVELOPMENT AND BECOME MORE
UNCERTAIN.

ALTHOUGH THERE IS A LARGE-SCALE RIDGE OVERHEAD NEXT WEEK, THIS IS
NOT EXPECTED TO STOP THUNDERSTORMS FROM SPRINGING UP NEAR THE SIERRA
WITH DAYTIME HEATING AS TEMPERATURES ALOFT ARE NOT OVERLY WARM AND
ALL-DAY TERRAIN CONVERGENCE TYPICALLY ALLOWS CUMULUS TO BUILD INTO
AT LEAST ISOLATED THUNDERSTORMS. IN ADDITION, STRONG BASIN HEATING
WILL LIKELY START TO INDUCE A ZEPHYR LATE IN THE DAY WHICH COULD
ALLOW STORMS TO PUSH WELL OUT IN WESTERN NEVADA BY AROUND TUESDAY.
ALSO, IF ANY UPPER WAVES AND THEIR ASSOCIATED MOISTURE WORK AROUND
THE PERIPHERY OF THE RIDGE, SHOWERS/THUNDERSTORM COVERAGE COULD BE
ENHANCED. IN FACT, THE 00Z GFS/GEM/ECMWF PUT THE RIDGE AXIS OVER THE
EASTERN GREAT BASIN WITH MOISTURE WORKING SLOWLY INTO THE REGION
NEXT WEEK. HOWEVER, AS IT IS STILL TOO EARLY TO ASCERTAIN THE
PLACEMENT OR EVEN EXISTENCE OF SMALLER SCALE WAVES THE FORECAST WAS
BROAD-BRUSHED WITH A TREND TOWARDS INCREASING THUNDERSTORM COVERAGE
FROM EARLY TO MID NEXT WEEK.

TEMPERATURE-WISE NEXT WEEK, THEY WILL START OUT WELL ABOVE AVERAGE
ON SUNDAY AS THE RIDGE STRENGTHENS OVERHEAD. HOWEVER, AS WAS NOTED
ABOVE, HIGHS COULD BEGIN TO BE AFFECTED SUBSTANTIALLY DOWNWARD
MONDAY THROUGH WEDNESDAY AS CONVECTIVE COVERAGE INCREASES. WITH THE
EXPECTATION FOR INCREASING CONVECTION FIRST NEAR THE SIERRA, I
STARTED TO TREND DOWN HIGHS FOR EASTERN CALIFORNIA AND FAR WESTERN
NEVADA MONDAY AND TUESDAY WITH A SLOWER DECLINE FOR THE BASIN AND
RANGE AS THOSE AREAS ARE LIKELY TO BE THE LAST TO SEE SUBSTANTIAL
CONVECTIVE CLOUD COVERAGE. SNYDER

&&

.AVIATION...
VFR WITH MINIMAL CONCERNS THROUGH FRIDAY. THE TYPICAL WEST BREEZES
WILL PRODUCE GUSTS TO 25 KT IN THE AFTN/EVE (GENERALLY BTWN 21-06Z).
DUE TO THE WEST-SOUTHWEST FLOW ALOFT, THERE COULD ALSO BE A
THUNDERSTORM OR TWO ACROSS NORTHERN LASSEN AND WASHOE COUNTIES DUE
TO TERRAIN-FORCED CONVERGENCE DOWNWIND OF LASSEN PEAK. THE ATMOSPHERE
SHOULD STABILIZE ENOUGH TO ELIMINATE ANY STORMS THERE ON FRIDAY.
