AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
204 PM PDT WED JUL 16 2014

.SYNOPSIS...
ABUNDANT MOISTURE...INSTABILITY AND LIGHT WINDS ALOFT WILL LEAD TO
SLOW MOVING THUNDERSTORMS WITH HEAVY RAIN AND GUSTY OUTFLOW WINDS.
A FLASH FLOOD WATCH IS IN EFFECT FOR PORTIONS OF THE SIERRA AND
WESTERN NEVADA THROUGH FRIDAY. FOR THIS WEEKEND THROUGH EARLY NEXT
WEEK...LOW PRESSURE APPROACHING THE PACIFIC NORTHWEST WILL BRING A
DRYING TREND AND BREEZY WINDS.

&&

.SHORT TERM...
MAIN ISSUE IS THE FLASH FLOOD POTENTIAL THROUGH FRIDAY.
THUNDERSTORMS WILL DEVELOP EACH DAY WITH A FEW SHOWERS AND PERHAPS
A THUNDERSTORM DURING THE OVERNIGHT AND EARLY MORNING HOURS. IN
ADDITION TO THE HEAVY RAIN THUNDERSTORMS MAY PRODUCE OUTFLOW WINDS
OF 30 TO 50 MPH. ONLY POTENTIAL DRAWBACK TO THUNDERSTORMS IS
CLOUD COVER FROM THE PREVIOUS DAYS CONVECTION, WHICH WOULD LIMIT
INSTABILITY DUE TO A LACK OF SURFACE HEATING.

THERE IS NO CHANGE TO THE FORECAST REASONING WITH ABUNDANT
MOISTURE...INSTABILITY AND LIGHT STEERING FLOW ALOFT. ANTECEDENT
MOIST SOILS AND CREEK BEDS WILL START TO PLAY A BIGGER ROLE IN THE
FLASH FLOOD THREAT TOMORROW AND FRIDAY, ESPECIALLY ACROSS ALPINE,
MONO AND WESTERN MINERAL COUNTY.

FOR THIS EVENING, BEST THUNDERSTORM COVERAGE WILL BE FROM SIERRA
COUNTY TO THE RENO-SPARKS NORTH VALLEYS SOUTHWARD TO MONO AND
WESTERN MINERAL COUNTY. ISOLATED THUNDERSTORMS WILL ALSO IMPACT PLUMAS
AND LASSEN COUNTIES.

FOR THURSDAY THE FLASH FLOOD THREAT WILL EXTEND AS FAR NORTH AS
PLUMAS, LASSEN AND THE SURPRISE VALLEY. MODELS ARE SHOWING AN
ACTIVE LASSEN CONVERGENCE ZONE AS THE WINDS ALOFT NORTH OF
SUSANVILLE-GERLACH SHIFT TO THE SOUTHWEST. FARTHER SOUTH MODELS
ARE HINTING AT A WEAK ZEPHYR DEVELOPING, WHICH MAY HELP FOCUS A
FEW STRONGER CELLS ALONG HIGHWAY 395.

BY FRIDAY A TROUGH STARTS TO APPROACH THE PACIFIC NORTHWEST. THIS
WILL SHIFT THE RIDGE AXIS TO OUT EAST WITH AN INCREASING
SOUTHWEST FLOW ALOFT NORTH OF INTERSTATE 80. A 10-15 MPH STORM
MOTION NORTH OF INTERSTATE 80 GREATLY LIMITS THE FLASH FLOOD
THREAT. HOWEVER SOUTH OF INTERSTATE 80 THE WINDS ALOFT WILL REMAIN
LIGHT, THOUGH THEY WILL START TO TURN TO THE SOUTHWEST. THE RIDGE
AXIS MOVING TO OUR EAST WILL CREATE A 10-15 MPH ZEPHYR WIND IN THE
AFTERNOON. MAIN CONCERN HERE IS THE ZEPHYR ACTING AS A SURFACE
BOUNDARY WITH POTENTIAL FOR ORGANIZED STORMS PERSISTING FOR A FEW
HOURS. HIGHEST FLASH FLOOD THREAT WOULD SET UP ALONG AND JUST
EAST OF HIGHWAY 395 FROM CA/NV STATE LINE SOUTH THROUGH RENO-
SPARKS TO DOUGLAS/LYON COUNTIES AND INTO EASTERN MONO/WESTERN
MINERAL COUNTIES. THIS INCLUDES THE BISON FIRE BURN SCAR. BRONG

.LONG TERM...SATURDAY THROUGH WEDNESDAY...
THE LARGE SCALE PATTERN IN THE EXTENDED FORECAST WILL FOCUS ON THE
DEVELOPMENT OF AN UPPER LEVEL TROUGH OFF THE WEST COAST THIS WEEKEND
AND INTO EARLY NEXT WEEK. THIS WILL RESULT IN A DRIER PATTERN WITH
TEMPERATURES NEAR SEASON AVERAGES. PERIODS OF BREEZY WINDS ARE
POSSIBLE AS THE TROUGH BEGINS TO PUSH ONSHORE NEXT WEEK. LINGERING
MOISTURE AND INSTABILITY SHOULD BE SUFFICIENT TO ALLOW FOR SHOWERS
AND STORMS TO DEVELOP WITH THE BEST CHANCES EXISTING MAINLY SOUTH OF
HWY 50. BY SUNDAY THE OFFSHORE TROUGH BEGINS TO DEEPEN AND
INCREASES A DRIER SOUTHWESTERLY FLOW ALOFT. THIS SHOULD BEGIN TO
DIMINISH PRECIPITATION CHANCES SUNDAY INTO EARLY NEXT WEEK WITH AN
INCREASE IN WINDS EXPECTED. FIRE WEATHER CONCERNS ARE POSSIBLE WITH
THE INCREASE IN WINDS AND DRIER CONDITIONS, ESPECIALLY NORTH OF HWY
50 WHERE DRIER CONDITIONS HAVE EXISTED.

THE PAST FEW MODEL RUNS HAVE SHOWN BROAD AGREEMENT IN DEVELOPING
THIS TROUGH OFFSHORE BUT HAVE HAD SOME DIFFICULTY AGREEING ON HOW
FAR INLAND THE TROUGH WILL PENETRATE. THIS MORNING'S MODEL RUNS HAVE
SHOWN CONSISTENCY WITH LAST NIGHTS RUNS IN KEEPING THE TROUGH
FURTHER INLAND WHICH WOULD PROVIDE BETTER POTENTIAL FOR INCREASED
WINDS. HAVE TRENDED WIND SPEEDS UP A BIT SUNDAY THROUGH TUESDAY BUT
CONSIDERABLE ENSEMBLE SPREAD REMAINS SO CONFIDENCE REMAINS ON THE LOWER
END MAINLY ON TIMING ITS INLAND PROGRESSION. FUENTES

&&

.AVIATION...
THUNDERSTORMS WILL BE THE MAIN FOCUS THROUGH FRIDAY WITH THE MAIN
THREATS BEING LOCALLY HEAVY RAINS, OUTFLOW WIND GUSTS TO 40 KTS, AND
SMALL HAIL POSSIBLE.

THUNDERSTORMS WILL BE POSSIBLE FROM THRU 04Z THIS EVENING WITH THE
BEST THREAT SOUTHEAST OF A RENO-PORTOLA LINE WITH MORE ISOLATED
STORMS ELSEWHERE. ON THURSDAY, MOST AREAS SHOULD SEE A STRONG CHANCE
AT STORMS WITH HEAVY RAINFALL EXCEPT NORTHEAST OF A LOVELOCK-GERLACH
LINE WHERE THEY WILL REMAIN ISOLATED. FRIDAY ALSO LOOKS TO BE AN
ACTIVE DAY BEFORE THE THREAT DIMINISHES THIS WEEKEND. WALLMANN/TF
