AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
214 AM PDT WED JUN 12 2013

.SYNOPSIS...

WINDY CONDITIONS CAN BE EXPECTED TODAY AHEAD OF A TROUGH MOVING
INTO THE WEST COAST WITH WIDESPREAD GUSTS OF 30 TO 40 MPH. THIS
WILL CAUSE ROUGH AND CHOPPY WATERS ON AREA LAKES. THE INCREASED
WINDS AND DRY AIR WILL CREATE CRITICAL FIRE WEATHER CONDITIONS
FOR PORTIONS OF THE EASTERN SIERRA AND WESTERN NEVADA.
TEMPERATURES WILL COOL OFF THURSDAY BEFORE WARMING BACK UP TO
NEAR NORMAL THIS WEEKEND.

&&

.SHORT TERM...

DRY, SOUTHWEST FLOW REMAINS ACROSS THE REGION THIS MORNING AND
WHILE A WEAK SHORTWAVE IS LIFTING THROUGH NEVADA EARLY THIS
MORNING, IT APPEARS THE MAIN IMPACT WILL ONLY BE CLOUDS. THERE IS
A SMALL CHANCE A FEW SPRINKLES OF RAIN MAY REACH THE GROUND
THROUGH THE CENTRAL NEVADA BASIN, BUT WITH THE STABILIZING
ATMOSPHERE, HAVE DECIDED TO LEAVE MENTIONABLE WEATHER OUT OF THE
FORECAST.

THE GREATEST CONCERN TODAY IS THE INCREASING SOUTHWEST WINDS
AHEAD OF A TROUGH DIGGING INTO THE WEST COAST. WIDESPREAD GUSTS OF
30 TO 40 MPH CAN BE EXPECTED WITH LOCALLY HIGHER GUSTS THROUGH
WIND PRONE AREAS. THESE WINDS WILL CAUSE ROUGH AND CHOPPY WATERS
ON ALL AREA LAKES AND LAKE WIND ADVISORIES REMAIN IN EFFECT. IN
ADDITION TO THE WINDS, A MUCH DRIER AIR MASS SHIFTS INTO NORTHEAST
CALIFORNIA, THE SIERRA, AND WESTERN NEVADA AND THE COMBINATION OF
WIND AND LOW HUMIDITY WILL CREATE CRITICAL FIRE WEATHER
CONDITIONS. RED FLAG WARNINGS ARE IN EFFECT FOR MUCH OF THE SIERRA
AND WESTERN NEVADA. PLEASE SEE THE FIRE WEATHER SECTION BELOW FOR
ADDITIONAL DETAILS.

AS THE MAIN UPPER LOW MOVES ACROSS THE PACIFIC NORTHWEST ON
THURSDAY, INCREASING MOISTURE AND INSTABILITY MAY TRIGGER THE
LASSEN CONVERGENCE ZONE. THEREFORE, A SLIGHT CHANCE OF THUNDERSTORMS
WILL REMAIN IN THE FORECAST FOR LASSEN AND NORTHERN WASHOE
COUNTIES THURSDAY AFTERNOON. OTHERWISE, DRY AND STABLE CONDITIONS
WILL BE IN PLACE FOR THE REMAINDER OF THE WORK WEEK. TEMPERATURES
WILL DROP SLIGHTLY BELOW NORMAL THURSDAY WITH THE TROUGH PASSAGE,
BUT WILL QUICKLY RETURN TO NEAR NORMAL HEADING INTO THE WEEKEND.
DF

.LONG TERM...SATURDAY THROUGH TUESDAY...

TROUGH ALONG THE WEST COAST WITH DRY SOUTHWEST WILL CONTINUE THIS
THE WEEKEND.  THIS WILL HELP MAINTAIN BREEZY AFTERNOON AND EVENING
WINDS WITH HIGHS WITHIN A FEW DEGREES OF NORMAL. THE TROUGH SHOULD
MOVE INTO THE PACIFIC NORTHWEST EARLY NEXT WEEK WITH A VERY LOW
CHANCE OF SHOWERS AND THUNDERSTORMS FOR THE SURPRISE VALLEY AND THE
FAR NORTHERN PORTIONS OF LASSEN AND WASHOE COUNTIES.

THE GUSTY WINDS WILL IMPACT BOATING CONDITIONS ON AREA LAKES WITH
PEAK GUSTS UP TO 30 MPH FOR THE WEEKEND.  FOR MONDAY AND TUESDAY
GUSTS COULD BE AS HIGH AS 40 MPH ALONG THE HIGHWAY 395 CORRIDOR AS
THE TROUGH MOVES INLAND.  BRONG

&&

.AVIATION...

DRY AND STABLE SOUTHWEST FLOW TODAY AND THURSDAY, WITH LIGHTER
WINDS FOR THE END OF THE WEEK. PEAK AFTERNOON GUSTS SHOULD REACH
35 KTS ACROSS THE SIERRA AND WESTERN NEVADA TERMINALS. BRONG


&&

.FIRE WEATHER...

* CRITICAL CONDITIONS TODAY WITH GUSTS 30-45 MPH AND LOW HUMIDITY.

DRY SOUTHWEST FLOW FOR TODAY WITH TROUGH ALONG THE PACIFIC NORTHWEST
COAST AND JET SEGMENT OVER THE EASTERN SIERRA AND WESTERN NEVADA.
RED FLAG CONDITIONS WILL OCCUR ALONG AND SOUTH OF A LINE FROM
TRUCKEE TO PYRAMID LAKE TO WINNEMUCCA. GUSTS FOR MOST LOCATIONS
IN THIS AREA WILL REACH 30 MPH BY LATE MORNING TO EARLY AFTERNOON
WITH GUSTS AS HIGH AS 45 MPH IN WIND PRONE AREAS ALONG HIGHWAYS
50...95 AND 395.

A PIECE OF ENERGY FROM THE TROUGH OVER THE PACIFIC NORTHWEST WILL
PASS THROUGH SOUTHERN OREGON ON THURSDAY.  THIS COULD WILL LIKELY
PUSH GUSTS BACK ABOVE 30 MPH, BUT WITH COOLER TEMPERATURES AND
HIGHER HUMIDITY POTENTIAL FOR CRITICAL CONDITIONS WILL BE PUSHED
TO THE SOUTH OF INTERSTATE 80.

WINDS WILL LIGHTEN FOR FRIDAY AS THE TROUGH RELOADS OFF THE WEST
COAST.  BREEZY CONDITIONS WILL RETURN AS EARLY AS SATURDAY WITH A
SECOND PERIOD OF 30-40 MPH POSSIBLE EARLY NEXT WEEK.  BRONG
