DISCUSSION
PACIFIC NORTHWEST TROUGHING WILL MAKE FOR A COOLER THAN NORMAL LABOR
DAY WEEKEND WITH DAYTIME HIGHS IN THE 60S AND 70S THROUGH MONDAY.
SW/W WIND GUSTS INCREASE TO 30-40 MPH SUNDAY AFTERNOON IN RESPONSE
TO AN APPROACHING COLD FRONT, POSING IMPACTS TO HOLIDAY TRAVEL AND
RECREATION (I.E., BUMPY FLIGHTS, CHOPPY LAKE WATERS). THESE WINDS
ALSO ELEVATE FIRE CONCERNS FROM MONO COUNTY INTO S.LYON AND MINERAL
COUNTIES WHERE DAYTIME HUMIDITY IS LOW (MORE DETAILS IN THE FIRE
WEATHER SECTION BELOW). THE AFOREMENTIONED COLD FRONT WILL INCREASE
SHOWER CHANCES TO 30-60% FOR AREAS NORTH OF A SUSANVILLE-GERLACH
LINE ON SUNDAY, WITH A LOW 10-30% CHANCE OF THUNDERSTORMS IN THE
AFTERNOON. LABOR DAY IS FAVORED TO BE DRY WITH WEAKER (ALBEIT STILL
BREEZY) WINDS IN THE AFTERNOON.
A SLOW WARMING TREND WILL BRING TEMPERATURES CLOSER TO THE SEASONAL
AVERAGES AFTER MONDAY, WITH DAYTIME HIGHS STAYING IN THE 70S AND 80S
FOR MUCH OF THE WEEK. SOUTHERLY FLOW ALOFT WILL DRAW DEEP MOISTURE
NORTHWARD INTO THE REGION AROUND MIDWEEK, INCREASING SHOWER AND
THUNDERSTORM CHANCES BETWEEN TUESDAY AND THURSDAY. THE EASTERN
SIERRA FROM TAHOE SOUTHWARD IS MOST FAVORED FOR ANY RAIN AND STORMS,
BUT CONFIDENCE REMAINS LOW ON EXACT TIMING/LOCATION DETAILS.

AVIATION
VFR CONDITIONS PREVAIL. WINDS ARE EXPECTED TO BE WEAKER TODAY,
BUT S/SW GUSTS OF 20-25 KTS SHOULD ARRIVE IN THE EARLY AFTERNOON
BEFORE SHIFTING TO MORE W/SW IN THE LATE AFTERNOON.
WINDS ALOFT AND AT THE SURFACE INCREASE ON SUNDAY, RENEWING LLWS AND
MOUNTAIN WAVE TURBULENCE POTENTIAL FOR ALL MAIN TERMINALS. GUSTY
WINDS MAY ALSO PRODUCE BLOWING DUST AND REDUCED VISIBILITIES AT KHTH-
KNFL-KLOL SUNDAY AFTERNOON.
-SALAS
FIRE WEATHER
SW/W GUSTS OF 30-40 MPH AND RH REDUCTIONS TO 15% OR LESS WILL
SUPPORT 2-5 HOURS OF CRITICAL CONDITIONS ACROSS VALLEYS AND MIDSLOPE
AREAS OF MONO, S. LYON, AND MINERAL COUNTIES SUNDAY AFTERNOON. WIND
SHIFT TO A MORE WESTERLY DIRECTION FOLLOWING A DRY FRONTAL PASSAGE
IN THE LATE AFTERNOON AND EARLY EVENING. NIGHTTIME RECOVERIES
WILL BE MODERATE TO GOOD (UP TO 50-70%) SUNDAY NIGHT INTO MONDAY,
WITH THE EXCEPTION OF THE CHALFANT VALLEY WHERE RH STRUGGLES TO
40%.
FARTHER NORTH, HIGHER HUMIDITY WILL MITIGATE FIRE CONCERNS SOMEWHAT,
BUT SIMILAR WIND GUSTS WILL AT LEAST ELEVATE FIRE CONCERNS FROM THE
NORTHERN SIERRA FRONT INTO THE WEST-CENTRAL NEVADA SUNDAY AFTERNOON.
