AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
237 PM PDT SAT AUG 30 2014

.SYNOPSIS...
LOW PRESSURE MOVING ACROSS THE PACIFIC NORTHWEST WILL CREATE DRY AND
BREEZY CONDITIONS THROUGH THIS EVENING. NEAR AVERAGE TEMPERATURES ARE
EXPECTED FOR THE HOLIDAY WEEKEND. TEMPERATURES WILL WARM A FEW
DEGREES EARLY NEXT WEEK WITH SLIGHTLY COOLER TEMPERATURES AND BREEZY
CONDITIONS POSSIBLE BY THE MIDDLE OF NEXT WEEK.

&&

.SHORT TERM...
A TIGHT SURFACE PRESSURE GRADIENT ALONG WITH AN EXITING UPPER LEVEL
JET WILL PRODUCE GUSTY WEST TO SOUTHWEST WINDS ACROSS THE REGION
THIS EVENING. WIND GUSTS UP TO 35 MPH WILL PRODUCE CRITICAL FIRE
WEATHER CONDITIONS FOR PORTIONS OF WESTERN NEVADA AND CHOPPY
WATERS ON AREA LAKES INCLUDING LAKE TAHOE AND PYRAMID LAKE. FOR
MORE DETAILS ON THE FIRE WEATHER CONCERNS, CHECK OUT THE FIRE
WEATHER DISCUSSION.

HIGH PRESSURE RETURNS ACROSS THE REGION AS THE LONGWAVE TROUGH
ACROSS THE PACIFIC NORTHWEST MOVES ACROSS THE ROCKIES. HIGH PRESSURE
WILL BRING LIGHT WINDS AND DRY CONDITIONS TO THE SIERRA AND WESTERN
NEVADA THROUGH EARLY NEXT WEEK. TEMPERATURES WILL ALSO INCREASE TO
NEAR NORMAL WITH RIDGING ACROSS THE REGION. ELW

.LONG TERM...TUESDAY THROUGH SATURDAY...
A PERSISTENT DRY SOUTHWEST FLOW WILL DEVELOP ACROSS THE REGION WITH
BROAD TROUGHING ACROSS THE WEST COAST. MODEL GUIDANCE IN GENERAL
CONSENSUS IN DEEPENING AN UPPER LEVEL TROUGH LATE TUESDAY WITH THE
TROUGH REMAINING IN PLACE THROUGH THE START OF NEXT WEEKEND. THIS
WILL PROVIDE LITTLE POTENTIAL FOR PRECIPITATION AND WILL KEEP US IN
A COOLER PATTERN WITH PERIODS OF BREEZY WINDS. MOSTLY CLEAR
CONDITIONS EXPECTED ACROSS THE REGION AS A RATHER LARGE SWATH OF DRY
AIR ALOFT PUSHES ACROSS CENTRAL CALIFORNIA. OVERALL, TEMPERATURES
WILL REMAIN NEAR SEASONAL AVERAGES WITH HIGHS IN THE MID TO UPPER
80S ACROSS WESTERN NEVADA AND MID TO UPPER 70S ACROSS SIERRA
VALLEYS. THE DRY AND CLEAR CONDITIONS WILL MAKE FOR EFFICIENT
COOLING ALLOWING FOR A FEW COLDER SIERRA VALLEYS TO REACH LOWS IN
THE 30S THROUGH NEXT WEEK. FUENTES

&&

.AVIATION...
GUSTY WINDS EXPECTED AGAIN THIS AFTERNOON AND EVENING WITH STRONGEST
WINDS FROM I-80 SOUTH INCLUDING KRNO/KCXP/KMMH WITH GUSTS 25-30KTS.
BLDU POSSIBLE AT KLOL/KNFL AND BURNING MAN AIRFIELD.

SOME LIGHT TO MODERATE MOUNTAIN WAVE TURBULENCE IS POSSIBLE ALONG
AND EAST OF THE SIERRA CREST THROUGH TONIGHT WITH THE STRONGER
WINDS ALOFT. LIGHTER WINDS SUNDAY AND MONDAY AS HIGH PRESSURE
BUILDS BACK INTO THE REGION. HOON/TF

&&

.FIRE WEATHER...
BREEZY AND DRY CONDITIONS WILL CONTINUE INTO THE EVENING HOURS
TONIGHT WITH ANOTHER ROUND OF POOR TO MODERATE OVERNIGHT RECOVERIES.
AFTERNOON WINDS AND LOW RELATIVE HUMIDITY HAVE REACHED CRITICAL
CONDITIONS ALONG THE SIERRA FRONT INTO CENTRAL NEVADA. THIS EVENT
HAS BEEN MORE ON THE MARGINAL SIDE EARLY SATURDAY, BUT IS BECOMING
MORE CONSISTENT THIS AFTERNOON ESPECIALLY ALONG THE NEVADA SIERRA
FRONT. WINDS ARE LACKING INTO THE NEVADA INTERIOR, BUT SHOULD PICK
UP LATE IN THE AFTERNOON AND CONTINUE INTO THE EVENING. LOCALIZED
RED FLAG CONDITIONS ARE APPARENT IN MONO COUNTY BUT THESE AREAS
SHOULD ONLY HIT SPORADICALLY THROUGH THE REST OF THE DAY.

RECOVERIES OVERNIGHT AND THE NEXT COUPLE OF NIGHTS WILL BE POOR TO
MODERATE AS DRY CONDITIONS LINGER. FORTUNATELY, WINDS WILL NOT BE
STRONG AND RED FLAGS WILL NOT BE A CONCERN. WILL CONTINUE TO WATCH
FOR THE POTENTIAL LATE THIS WEEK AS A POSITIVELY TILTED TROUGH
APPROACHES THE REGION. IF THIS TROUGH HOLDS TOGETHER, RED FLAG
CRITERIA COULD BE MET AGAIN ALONG THE SIERRA FRONT INTO THE SIERRA.
THIS TYPE OF TROUGH FAVORS RED FLAG CONDITIONS FOR THE TAHOE BASIN.
HOWEVER, THERE COULD BE A LOT OF VARIATION BETWEEN NOW AND THE END
OF THIS WEEK SO JUST MENTIONING AS AN OUTSIDE CHANCE FOR NOW. BOYD
