AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
301 AM PDT THU JUL 4 2013

CORRECTED WORD WRAP IN LONG TERM DISCUSSION

.SYNOPSIS...
LOW PRESSURE MOVING ACROSS THE NORTHWEST US COMBINED WITH ABUNDANT
MOISTURE WILL PRODUCE THUNDERSTORMS WITH LOCALLY HEAVY RAIN,
STRONG GUSTY WINDS, HAIL AND FREQUENT LIGHTNING TODAY. ACTIVITY
WILL DIMINISH DURING THE EVENING. THUNDERSTORM CHANCES WILL
DECREASE FRIDAY AND THROUGH THE REMAINDER OF THE WEEKEND, AND BE
LIMITED MAINLY TO WEST CENTRAL NEVADA AND MONO COUNTY.
&&

.SHORT TERM...
IMPRESSIVE CLUSTER OF THUNDERSTORMS WHICH PRODUCED WELL OVER 1000
LIGHTNING STRIKES OVER CENTRAL WASHOE AND WESTERN PERSHING COUNTY
YESTERDAY EVENING HAS FINALLY WOUND DOWN, WITH THE RESIDUAL
MESOSCALE CONVECTIVE VORTEX MOVING ACROSS SOUTHERN HUMBOLDT
COUNTY. THE SUBSIDENCE IN THE WAKE OF THIS QUICKLY DEPARTING VORTEX
WILL CONTINUE THROUGH THE EARLY MORNING BUT THE AIR MASS WILL BE
ABLE TO RELOAD EARLIER IN THE DAY WITH THE FIRST CELLS POSSIBLY
FIRING UP BEFORE NOON NEAR THE SIERRA.

WITH THE TROUGH REACHING THE WEST COAST THIS AFTERNOON, SOUTHWEST
FLOW WILL INCREASE, RESULTING IN FASTER CELL MOTIONS COMPARED TO
YESTERDAY. HOWEVER, WITH PLENTY OF MOISTURE AND INSTABILITY IN
PLACE, THE POTENTIAL FOR STRONG OR LOCALLY SEVERE STORMS WILL
INCREASE WITH SIGNIFICANT UPDRAFTS PRODUCING HAIL AND CONVECTIVE
WIND GUSTS. HEAVY RAINFALL WILL STILL REMAIN A CONCERN AS LOW
LEVEL CONVERGENCE INCREASES, ESPECIALLY IN AREAS WHERE CELLS COULD
REDEVELOP AND MOVE ACROSS THE SAME AREA FOR AN HOUR OR TWO WITH
LITTLE VARIATION IN WIND DIRECTION ALOFT. OUTFLOW BOUNDARY
INTERACTIONS WILL TRIGGER ADDITIONAL STORM DEVELOPMENT DURING THE
EARLIER STAGES OF THE EVENT, WITH A PROBABLE EVOLUTION INTO A MORE
ORGANIZED THUNDERSTORM CLUSTER WITH A LARGER GUST FRONT PUSHING
EAST ACROSS THE WEST CENTRAL NV BASIN LATER IN THE AFTERNOON.

THE LOSS OF UPPER LEVEL FORCING AND DAYTIME HEATING WILL LEAD TO A
QUICKER WEAKENING TREND OF THUNDERSTORMS THIS EVENING ESPECIALLY
WEST OF HIGHWAY 95, WITH ONLY A FEW LINGERING CELLS MAINLY EAST OF
HIGHWAY 95 AFTER SUNSET. SYNOPTIC WINDS WITH THE TROUGH PASSAGE
ARE NOT VERY STRONG, MAINLY 10-15 MPH BUT THEY SHOULD GRADUALLY
DECREASE NEAR OR SHORTLY AFTER 10 PM AROUND THE RENO-CARSON CITY
VICINITY. IN THE TAHOE BASIN, WINDS SHOULD DIMINISH TO LESS THAN
10 MPH BY 8 PM. THIS WIND OUTLOOK WOULD ASSUME THAT ROGUE
THUNDERSTORMS DID NOT PERSIST LONGER THAN EXPECTED NEAR THESE
AREAS.

FOR FRIDAY, WEAK BAGGY TROUGH REMAINS NEAR THE WEST COAST WITH
SOUTHWEST FLOW CONTINUING ACROSS THE SIERRA. AFTER THE
THUNDERSTORM ACTIVITY OF TODAY, RESIDUAL LOW LEVEL MOISTURE WILL
PROBABLY LEAD TO SOME AFTERNOON CUMULUS DEVELOPMENT OVER MOST OF
THE REGION. INSTABILITY IS NOT AS IMPRESSIVE AND UPPER LEVEL LAPSE
RATES WITH DRIER AIR ALOFT WILL LIMIT THUNDERSTORM POTENTIAL, BUT
A FEW CELLS COULD STILL FORM NEAR SOME OF THE TYPICAL CONVERGENCE
ZONES SUCH AS NORTHERN LASSEN-NORTHWEST WASHOE, AND ALSO FROM WEST
CENTRAL NV SOUTH TO MINERAL-MONO COUNTIES. ANY STORMS THAT DEVELOP
WILL MORE LIKELY BE PULSE TYPE WITH BRIEF HEAVY RAIN AND POSSIBLE
SMALL HAIL BUT NOT AS INTENSE OR PERSISTENT COMPARED TO TODAY. A
MODERATE ZEPHYR TYPE BREEZE IS EXPECTED ACROSS MUCH OF WESTERN NV
DURING THE AFTERNOON AND EVENING WITH GUSTS NEAR 30 MPH.

BY SATURDAY, DRYING TREND WILL CONTINUE WITH THE THREAT OF
ISOLATED THUNDER PUSHING FARTHER EAST, MAINLY EAST OF HIGHWAY 95.
THE LATE DAY ZEPHYR BREEZE IN WESTERN NV IS LIKELY TO BE A LITTLE
WEAKER COMPARED TO FRIDAY.

TRIPLE DIGIT TEMPERATURES WILL BE SPARSE TODAY, MAINLY LIMITED TO
THE WARMER VALLEYS OF WEST CENTRAL NV. FOR THE REMAINDER OF THE
HOLIDAY WEEKEND, HIGHS WILL GENERALLY RANGE FROM THE MID TO UPPER
90S IN WESTERN NV AND LOWER TO MID 80S IN THE SIERRA VALLEYS. THE
LARGER CONTRAST FROM THE RECENT HEAT WAVE WILL BE FELT AT NIGHT, AS
EVENINGS COOL OFF QUICKER AND MIN TEMPS DROP CLOSER TO MORE TYPICAL
VALUES OF UPPER 50S TO MID 60S IN LOWER ELEVATIONS, AND 40S IN THE
SIERRA VALLEYS. MJD

.LONG TERM...SUNDAY THROUGH WEDNESDAY...
THE LONG TERM FORECAST REMAINS ON TRACK WITH HIGH PRESSURE OVER THE
GREAT BASIN THROUGH MIDWEEK. WEAK INSTABILITY LINGERS OVER CENTRAL
NEVADA MONDAY, ENOUGH THAT AN ISOLATED STORM CAN NOT BE RULED OUT
FOR THE MONO/MINERAL CONVERGENCE ZONE AND ACROSS FAR EASTERN
CHURCHILL AND PERSHING COUNTIES. ON TUE-WED THE RIDGE DEVELOPS
SLIGHTLY WITH A NEW AXIS OVER THE GREAT BASIN. THIS SHOULD PROVIDE A
DRY STABLE SOUTHWEST FLOW ACROSS THE SIERRA AND WESTERN NV WITH A
WEAK ZEPHYR FOR THE SIERRA FRONT EACH AFTERNOON. ALSO EXPECT
SLIGHTLY WARMER TEMPERATURES TUE-WED WITH HIGHS FOR THE WARMER
LOCATIONS IN THE WESTERN NEVADA DESERT EXCEEDING 100 DEGREES.
WEDNESDAY A WEAK LOW-PRESSURE SYSTEM APPROACHES THE CALIFORNIA
COAST. THIS COULD TURN THE MID-LEVEL FLOW MORE SOUTHERLY AND
POSSIBLY BRING AN INCREASE OF WIND AND INSTABILITY BY THE END OF THE
WEEK. JCM
&&

.AVIATION...
ISOLATED THUNDERSTORMS ARE POSSIBLE THIS MORNING MAINLY OVER THE
SIERRA. BY 1300 THE THREAT FOR SCATTERED THUNDERSTORMS SPREADS
FROM THE SIERRA TO NORTHEAST CALIFORNIA AND ALL OF WESTERN NEVADA.
SOME STORMS WILL PRODUCE STRONG ERRATIC OUTFLOW GUSTS AS WELL AS
HAIL AND HEAVY RAIN. GUSTY WINDS COULD CREATE REDUCTIONS TO VSBY
OVER THE BASIN AND RANGE DUE TO BLOWING DUST. LOCALLY HEAVY RAIN
WILL RESULT IN LOWERED CIGS AND VSBYS WITH IFR VSBYS POSSIBLE.
CONVECTIVE TURBULENCE AND LIGHTNING WILL ALSO BE A DANGER TO
AIRCRAFT NEAR THUNDERSTORMS TODAY. JCM
