AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
311 PM PDT SAT AUG 4 2007

.SHORT TERM...
STRONG GUSTY WINDS AND DRY CONDITIONS ALONG THE SIERRA FRONT WILL
CONTINUE INTO THIS EVENING...DYING OFF TONIGHT. WINDS WILL AGAIN
INCREASE TOMORROW MORNING...PROMPTING ANOTHER RED FLAG WARNING FOR
TOMORROW. SEE FIRE WEATHER DISCUSSION FOR MORE DETAILS.

UPPER LOW OFF THE CA COAST WILL MERGE INTO THE MAIN POLAR FLOW AS A
STRONG SHORTWAVE TROUGH...MOVING ONSHORE INTO NORTHERN CA OVERNIGHT
TONIGHT. AS THE SHORTWAVE MOVES CLOSER TO THE WESTERN GREAT
BASIN...PRESSURE GRADIENT WILL TIGHTEN SIGNIFICANTLY IN RESPONSE.
THIS WILL CAUSE US HAVE ANOTHER DAY OF STRONG GUSTY WEST TO
SOUTHWEST WINDS...WITH GUSTS NEAR 35 MPH AND STRONGER GUSTS ALONG
RIDGE TOPS AND WIND PRONE AREAS.

THIS POTENT SHORTWAVE IS EXPECTED TO HAVE SOME IMPRESSIVE DYNAMICS
ALOFT AS IT APPROACHES THE AREA...INCLUDING A VERY STRONG JET STREAK
FOR THIS TIME OF YEAR AROUND 95 KTS AND GOOD COLD AIR ADVECTION
ALOFT THAT WILL STEEPEN LAPSE RATES ACROSS THE AREA. ISOLATED ELEVATED
CONVECTION WILL BEGIN AROUND MIDDAY TOMORROW...MAINLY TO THE EAST OF
RENO. STORMS WILL HAVE VERY FAST CELL MOVEMENT...PUSHING
NORTHEASTWARD. GIVEN THE DRY ENVIRONMENT AND FAST STORM
MOVEMENT...ANY CELLS THAT DEVELOP TOMORROW SHOULD BE DRY AND CAPABLE
OF PRODUCING LOCALIZED SEVERE DOWNBURST WINDS. ISOLATED DRY
THUNDERSTORM COVERAGE WILL SPREAD EASTWARD THROUGH THE DAY AS THE
SHORTWAVE MOVES ACROSS THE AREA. BY TOMORROW EVENING...STORM
ACTIVITY WILL PUSH NORTHEAST OF THE AREA...LEAVING MOSTLY CLEAR
SKIES AND DRY AIR ALOFT. GUSTY GRADIENT WINDS WILL BEGIN TO WEAKEN
AFTER THE WAVE MOVES UP INTO IDAHO.

ON A POSITIVE NOTE...TEMPERATURES OVER THE NEXT COUPLE DAYS WILL BE
QUITE PLEASANT...ACTUALLY DROPPING BELOW NORMAL FOR A CHANGE FOR
HIGHS...MID-UPPER 80S EXPECTED ACROSS THE DESERT VALLEYS AND 70S IN
THE HIGH SIERRA. LOWS WILL BE A BIT ON THE COOLER SIDE... WHICH WILL
BE MOST NOTICEABLE MONDAY AND TUESDAY FOR EARLY MORNING COMMUTERS.
HOON

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
NO MAJOR CHANGES IN THE EXTENDED.  AS WITH PREVIOUS RUNS THE MEDIUM
RANGE MODELS ARE SHOWING A STRONG RIDGE OVER THE SERN CONUS ON
WEDNESDAY.  THEY ALSO PROG THIS RIDGE TO STRENGTHEN AND RETROGRADE
INTO THE CNTRL PLAINS FRIDAY AND SATURDAY.  THIS BLOCKING RIDGE WILL
KEEP A WEAK TROUGH OVER THE WEST COAST THROUGH THE PERIOD.  WEAK
WSWLY FLOW ALOFT WILL GIVE THE NRN SIERRA AND NWRN NEVADA DRY
CONDITIONS WEDNESDAY THROUGH FRIDAY.

THE RIDGE SHOULD MOVE WEST TO THE PLAINS ON SATURDAY AND THIS WILL
HELP TO AMPLIFY THE FLOW OVER THE WRN CONUS.  THE UPPER FLOW WILL
BACK TO MORE SWLY AS A RESULT.  THE GRADIENT BETWEEN THE WRN TROUGH
AND THE RIDGE TO THE EAST WILL TIGHTEN AND THIS WILL CAUSE WIND
SPEEDS TO INCREASE OVER THE KREV CWFA ON SATURDAY.  DAYTIME TEMPS ON
WEDNESDAY WILL BE A FEW DEGREES BELOW NORMAL. TEMPERATURES HOWEVER
WILL INCREASE TO NEAR NORMAL LEVELS BY FRIDAY AND SATURDAY.  OHARA

&&

.AVIATION...
VFR CONDITIONS THROUGH SUNDAY.  GUSTY WINDS ARE POSSIBLE THIS AFTN
AND EVENING FROM 20Z THRU 03Z.  OHARA

&&

.FIRE WEATHER...
UPPER LOW OFF THE BAY AREA WILL GET PICKED UP AND PUSHED THROUGH THE
AREA BY SUN AFTERNOON. SO FAR...WINDS HAVE INCREASED BUT NOT BLOWING
QUITE AS STRONG AS EXPECTED. SUSPECT THAT THE EAST SFC GRADIENT FROM
THE UPPER LOW IS FIGHTING THE PREVAILING SW FLOW ALOFT. STILL
GETTING WINDS RIGHT AROUND RED FLAG CRITERIA IN AREAS WITH THE
WARNING AND AS SFC GRADIENT BECOMES WEST LATE...EXPECT A FURTHER
INCREASE IN WINDS. HAVE EXTENDED THE WARNING THROUGH 10 PM...AS A
FEW WINDY SITES DID NOT DECOUPLE UNTIL ABOUT THAT TIME LAST NIGHT.

TONIGHT AS THE UPPER LOW MOVES THROUGH...WINDS WILL INCREASE FURTHER
ON THE RIDGES. STILL EXPECT THE DECOUPLING TO HOLD TONIGHT...BUT THE
RADIATION INVERSION THAT DOES FORM SHOULD BE WEAK. ALSO EXPECT
HORRIBLE HUMIDITY RECOVERY MID-SLOPES WITH A FEW SITES LIKELY TO
REMAIN BELOW 15% WITH OTHERS 20-30% EXCEPT THE COLDEST VALLEYS.

WITH A WEAK INVERSION...STRONGER GRADIENT AT THE SFC AND
ALOFT...EXPECT WINDS TO INCREASE EARLY TOMORROW. HAVE STARTED THE
WARNING AT 10 AM AS A RESULT...BUT WOULD NOT BE SURPRISED FOR
FAVORED WINDY LOCATIONS (WALKER...GALENA...ETC) TO BE HITTING
CRITERIA BY 8 AM. WINDS SHOULD BE STRONGER TOMORROW IN THE DESERTS
WITH SUSTAINED WINDS 20-25 MPH AND GUSTS AROUND 40 MPH. EXPECT
INCREASED WINDS IN 271/272 AS WELL WHICH NORMALLY DONT BLOW AS HARD
AS THE DESERTS WITH GUSTS TO 35 MPH EXPECTED.

FINAL ISSUE IS POTENTIAL FOR DRY LIGHTNING ACROSS WESTERN NEVADA
SUNDAY. INSTABILITY IS NOT THAT GREAT...BUT DYNAMICS FROM
APPROACHING LOW ARE VERY IMPRESSIVE AND WILL BRING IN JUST ENOUGH
MID-LEVEL MOISTURE FOR SOME ISOLATED DRY THUNDERSTORMS. WOULD NOT BE
SURPRISED TO SEE MORE SCATTERED COVERAGE AS MODELS (AND WE
FORECASTERS) CAN UNDERESTIMATE WHAT THESE NEG TILT SYSTEMS CAN DO IN
SOMEWHAT DRY ENVIRONMENTS LIKE THIS. HOWEVER...NOT ENOUGH CONFIDENCE
IN THIS IDEA AND WILL KEEP ISOLD AND MENTION IN THE WARNING FOR
ZONES 453/459. WALLMANN
