AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
233 AM PDT SUN JUN 9 2013

.SYNOPSIS...

ONE LAST DAY OF RECORD HIGH TEMPERATURES TODAY AHEAD OF AN AREA OF
LOW PRESSURE LIFTING THROUGH CALIFORNIA AND NEVADA THIS AFTERNOON
INTO MONDAY. THIS WILL BRING CHANCES FOR SHOWERS AND THUNDERSTORMS
TO THE REGION. STORMS TODAY MAY PRODUCE STRONG AND ERRATIC WINDS
IN EXCESS OF 50 MPH. FOR THE UPCOMING WEEK, DRY CONDITIONS ARE
EXPECTED AS TEMPERATURES DROP CLOSER TO SEASONAL AVERAGES, WITH
BREEZY AFTERNOON WINDS THROUGH WEDNESDAY.

&&

.SHORT TERM...

FAIRLY COMPLEX WEATHER PATTERN SETTING UP OVER THE NEXT COUPLE OF
DAYS AS AN AREA OF LOW PRESSURE, CURRENTLY SITTING OFF THE
SOUTHERN CALIFORNIA COAST, LIFTS NORTHEAST AND BREAKS DOWN THE
RIDGE OF HIGH PRESSURE THAT HAS BEEN BRINGING SEVERAL DAYS OF
RECORD HEAT. RECORD HIGH TEMPERATURES ARE FORECAST ONCE AGAIN
TODAY IN SEVERAL LOCATIONS, BUT THIS WILL BE THE FINAL DAY OF THE
EXTREME HEAT.

BIGGEST CONCERN OF THE FORECAST REMAINS THE LOW THAT WILL LIFT
THROUGH THE REGION TODAY INTO MONDAY BRINGING THUNDERSTORMS TO THE
SIERRA, NORTHEAST CALIFORNIA, AND NORTHWEST NEVADA. THESE STORMS
WILL INITIALLY BE DRY AND THERE IS A CONCERN FOR LIGHTNING STRIKES
TO INITIATE NEW FIRES, THEREFORE THE FIRE WEATHER WATCH WAS
UPGRADED TO A RED FLAG WARNING AND EXPANDED IN COVERAGE. STORM
BASES WILL BE 12-15,000 FEET MSL AND WITH A VERY HOT AND DRY SUB-
CLOUD LAYER STRONG TO SEVERE WINDS OF 60 MPH OR MORE ARE LIKELY.
THIS ENVIRONMENT IS PERFECT FOR OUTFLOWS TO BE CARRIED WELL AHEAD
OF THE PARENT STORM AND OUTFLOWS COULD PICK UP DUST, CAUSING
VISIBILITY RESTRICTIONS. PLEASE SEE THE FIRE WEATHER SECTION
BELOW FOR ADDITIONAL DETAILS. STORMS ARE EXPECTED TO BECOME A HYBRID
BY EARLY THIS EVENING AND WILL BE WET ON MONDAY.

MODELS HAVE CONTINUED THE TREND OF SLOWING DOWN THE PROGRESSION OF
THE LOW LIFTING NORTHEAST AND ARE STILL DIFFERING IN THE EXACT
TRACK THIS COMPACT SYSTEM WILL TAKE. WHILE DIFFERENCES ARE SMALL,
THEY WILL HAVE AN IMPACT ON THE AREAS OF BEST THUNDERSTORM
COVERAGE. HAVE MADE ADJUSTMENTS TO THE FORECAST TO DELAY THE ONSET
OF THUNDERSTORMS AND TOOK THE AVERAGE CONSENSUS ON THE TRACK OF
THE LOW, WHICH TAKES THE CORE OF THE LOW OVER THE SOUTHERN SIERRA.
HIGHEST POPS ARE FOCUSED ALONG THE BEST AREA OF DEFORMATION MAINLY
STRETCHING ACROSS THE SIERRA AND INTO PORTIONS OF NORTHWESTERN
NEVADA.

TEMPERATURES TO DROP 15 TO 20 DEGREES AREA WIDE ON MONDAY COMPARED
TO SUNDAY DUE TO THE THUNDERSTORMS AND COOLER AIRMASS IN PLACE
OVER THE REGION. RIDGE TRIES TO REBUILD TUESDAY, BUT IS HELD IN
CHECK BY A DRY TROUGH CARVING INTO THE WEST. THIS WILL BRING
BREEZY WINDS TO THE REGION EACH AFTERNOON AND NEAR NORMAL
TEMPERATURES.

.LONG TERM...WEDNESDAY THROUGH SATURDAY...

30-40 MPH GUSTS REMAIN POSSIBLE WEDNESDAY WITH TROUGH PUSHING INTO
THE PACIFIC NORTHWEST, THOUGH WITH LITTLE TO NO MOISTURE.  MODELS
ARE DIGGING THE TROUGH A BIT FARTHER SOUTH FOR THURSDAY, WHICH MAY
DROP AFTERNOON HIGHS DOWN INTO THE UPPER 70S TO MID 80S FOR WESTERN
NEVADA AND MID 60S TO LOW 70S FOR THE SIERRA.

FRIDAY AND SATURDAY, MODELS DIVERGE A BIT WITH EITHER A SECOND
TROUGH MOVING INTO THE PACIFIC NORTHWEST FRIDAY OR SATURDAY WITH
THE TYPICAL SUMMER TIME AFTERNOON AND EVENING WINDS. THERE IS A
HINT OF SHOWERS AND THUNDERSTORMS DEVELOPING LATE IN THE WEEK
ACROSS LASSEN AND NORTHERN WASHOE COUNTIES. AFTERNOON HIGHS SHOULD
REMAIN NEAR NORMAL, 80S TO NEAR 90 FOR NEVADA VALLEYS AND 70S FOR
THE SIERRA. BRONG

&&

.AVIATION...

LOW OFF THE CALIFORNIA COAST WILL SLOWLY LIFT NORTH TODAY AND
TRACK ACROSS CENTRAL NEVADA FOR MONDAY.

THUNDERSTORMS WITH CLOUD BASES ABOVE 12,000 FEET SHOULD START TO
DEVELOP BY 21Z SOUTH OF TRUCKEE-CARSON CITY, THEN SPREAD NORTHWARD
INTO THE RENO AREA BY 00Z. MAIN THREAT IS POTENTIAL FOR SEVERE
OUTFLOW WINDS OVER 50 KTS. OUTFLOWS WILL KICK UP BLOWING DUST AND
COULD TRAVEL A LONG DISTANCE FROM THE THUNDERSTORMS THAT SPAWNED
THEM.

THUNDERSTORMS WILL CONTINUE SUNDAY NIGHT AND MONDAY AS LOW PRESSURE
TRACKS ACROSS NEVADA, THOUGH THE TREAT FOR STRONG OUTFLOW WINDS WILL
DECREASE.  BY MONDAY STORMS COULD PRODUCE MVFR CONDITIONS AND SMALL
HAIL.  BRONG

&&

.FIRE WEATHER...

* THUNDERSTORMS WITH DRY STRIKES AND STRONG/SEVERE OUTFLOWS TODAY.
* THUNDERSTORMS TURNING WETTER LATE TONIGHT AND MONDAY.
* 30-40 MPH GUSTS AND LOW HUMIDITY LIKELY TUESDAY AND WEDNESDAY.

WITH THE HIGH OVER NORTHERN NEVADA SHIFTING EAST AND LOW OFF THE
SOUTHERN CALIFORNIA COAST SLOWLY MOVING NORTHWARD, INSTABILITY WILL
INCREASE WITH HIGH BASED THUNDERSTORMS DEVELOPING OVER A HOT AND DRY
AIR MASS BELOW 12,000 FEET.  THIS IS A FAVORABLE SET UP FOR STORMS
TO PRODUCE DRY STRIKES WITH OUTFLOW WINDS OF 60 MPH OR MORE.  SOME
RAINFALL WILL REACH THE GROUND BUT THE DEEP DRY LAYER BELOW CLOUD
BASES WILL KEEP RAIN CORES SMALL. STORMS SHOULD FIRE BY MID
AFTERNOON FROM NORTHERN MONO, DOUGLAS, ALPINE, AND TAHOE BASIN THEN
SPREAD NORTHWARD DURING THE LATE AFTERNOON AND EARLY EVENING INTO
WASHOE, STOREY, CARSON CITY, LASSEN, AND PLUMAS COUNTIES.

THE TRANSITION TO WETTER STORMS WILL START LATER THIS EVENING AS
THE LOW PASSES OVER THE OWENS VALLEY. THE LOW WILL ALLOW STORMS TO
BE MORE EFFICIENT PRECIPITATION PRODUCERS WITH A BAND OF SHOWERS AND
STORMS DEVELOPING NORTH OF INTERSTATE 80 TONIGHT. ONE CONCERN IS
THE LARGE AMOUNT OF DRY AIR WRAPPING AROUND THE LOW TONIGHT WHICH
COULD INHIBIT NEW STORMS FROM DEVELOPING AFTER MIDNIGHT, EXCEPT
FOR AREAS FROM THE TAHOE BASIN NORTHWARD TO LASSEN COUNTY.

FOR MONDAY, STORMS SHOULD RE-DEVELOP BY LATE MORNING AS THE LOW
LIFTS INTO CENTRAL NEVADA WITH PLENTY OF INSTABILITY IN PLACE.
SURFACE COOLING WILL ALLOW RAINFALL TO REACH THE GROUND AND LIMIT
THE NUMBER OF DRY STRIKES. STRONG OUTFLOWS REMAIN POSSIBLE, BUT
SHOULD STAY BELOW 50 MPH.

TUESDAY AND WEDNESDAY, A TROUGH DEVELOPS OVER THE PACIFIC NORTHWEST
WITH A DRY AND STABLE SOUTHWEST FLOW ALOFT.  THIS WILL INCREASE
SURFACE GUSTS TO 30-40 MPH WITH AFTERNOON HUMIDITY NEAR AND BELOW
15%.  GUSTY WINDS GUSTY AFTERNOON AND EVENING WINDS SHOULD PERSIST
FOR THURSDAY AND FRIDAY BUT PEAK GUSTS SHOULD BE LOWER AS THE FLOW
ALOFT WEAKENS. BRONG
