AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE RENO NV  
155 PM PDT SAT AUG 27 2016  
   
SYNOPSIS
 
 
LIGHT WINDS AND HIGH TEMPERATURES A FEW DEGREES ABOVE AVERAGE ARE  
EXPECTED THROUGH THE WEEKEND. HIGH PRESSURE BREAKS DOWN MONDAY  
AND TUESDAY FOR INCREASING BREEZES, WITH COOLER TEMPERATURES  
LIKELY BY LATE WEEK.  
 

 
   
SHORT TERM
 
 
ADDED HAZE FOR RENO AND TAHOE THROUGH SUNDAY EVENING, OTHERWISE  
ONLY MINOR TWEAKS TO THE FORECAST.  
 
HIGH PRESSURE WILL BRING DRY AND WARM CONDITIONS INTO EARLY NEXT  
WEEK. TEMPERATURES WILL BE NEAR TO SLIGHTLY (3-6 DEGREES) ABOVE  
AVERAGE WITH HIGHS IN THE UPPER 80S TO MID 90S FOR WESTERN NEVADA  
VALLEYS AND LOW TO MID 80S IN SIERRA VALLEYS. AFTERNOON ZEPHYR  
WINDS ARE EXPECTED TO BE AVERAGE TO WEAK THROUGH SUNDAY. BY MONDAY,  
THE RIDGE OF HIGH PRESSURE BEGINS TO SLIP OFF TO THE SOUTH AND  
EAST WITH A SLIGHTLY STRONGER ZEPHYR POSSIBLE...ALTHOUGH THE  
INCREASE IS NOT EXPECTED TO BE ENOUGH TO WARRANT TOO MUCH FIRE  
WEATHER CONCERN.  
 
TUESDAY, AN UPPER DISTURBANCE WILL MOVE OVER NORTHERN CALIFORNIA  
AND INTO CENTRAL AND EASTERN OREGON. SIMULATIONS HINT AT SOME MID  
LEVEL CLOUDS OVER NORTHEAST CA AND NORTHWEST NV TUESDAY MORNING  
AND EARLY AFTERNOON AS THE DISTURBANCE, WHILE QUICK-MOVING,  
EXHIBITS SHARP FORCING AND MODERATE LAPSE RATES. THE QUESTION WILL  
BE...DOES THE FORCING HANG AROUND LONG ENOUGH TO PRODUCE DEEPER  
ELEVATED CONVECTION? AT THIS TIME, IT LOOKS TO BE MAINLY SOME  
ALTOCUMULUS WITH A FEW ACCAS EMBEDDED NORTH OF A PORTOLA TO  
PYRAMID LAKE TO GERLACH LINE.  
 
IF ANY SHOWERS OR THUNDERSTORMS FORM TUESDAY MORNING, THEY WILL  
VERY LIKELY BE DRY WITH SWIFT MID-LEVEL FLOW AND DRY SUB-CLOUD  
LAYERS. AT THIS TIME, THE CHANCES ARE LOW (10%) FOR ELEVATED  
CONVECTION TUESDAY MORNING. HOWEVER, WITH "DRY" LIGHTNING AND  
GUSTY OUTFLOW WINDS POSSIBLE, THE FIRE WEATHER COMMUNITY AND  
OUTDOOR EVENTS ACROSS NORTHEAST CA AND NORTHWEST NV SHOULD REMAIN  
INFORMED OF THE LATEST FORECASTS AND DISCUSSIONS, ESPECIALLY AS  
TUESDAY AFTERNOON COULD BRING GUSTY WINDS OF 25-35 MPH IN THE WAKE  
OF THE UPPER DISTURBANCE. SNYDER  
   
LONG TERM...WEDNESDAY THROUGH SATURDAY
 
 
THE SECOND HALF OF NEXT WEEK WILL FEATURE A BROAD UPPER TROUGH  
OVER THE WESTERN U.S. THIS WILL BRING PERIODS OF GUSTY WINDS AND  
A GRADUAL COOL DOWN BY LATE WEEK...WITH LITTLE CHANCE FOR RAIN  
UNTIL AT LEAST NEXT WEEKEND. HIGHS FOR THURSDAY AND FRIDAY WERE  
MODERATED/WARMED A TOUCH FOR SOME AREAS AS THE TROUGH DOES NOT  
LOOK QUITE AS DEEP, AT LEAST UNTIL NEXT WEEKEND. SNYDER  
 

 
   
AVIATION
 
 
VFR CONDITIONS ARE LIKELY THROUGH THE WEEKEND WITH MAINLY LIGHT  
WINDS. LATE AFTERNOON AND EARLY EVENING WINDS COULD INCREASE BY  
SUNDAY...BUT THIS IS MORE LIKELY MONDAY AS THERMAL GRADIENTS  
START TO INCREASE.  
 
SOME HAZE HAS LEAKED INTO FAR WESTERN NEVADA TODAY, AT LEAST  
PARTIALLY FROM THE MOKELUMNE FIRE ON THE WEST SLOPES OF THE  
SIERRA SOUTH OF LAKE TAHOE. WITH SOUTHWEST TO WEST WINDS ALOFT,  
HAZE COULD HANG AROUND PERIODICALLY FOR THE NEXT COUPLE DAYS  
(DEPENDING ON SMOKE PRODUCTION FROM FIRES)...POSSIBLY BRINGING  
SOME DECREASE IN SLANTWISE VISIBILITY FOR LANDINGS AT  
KRNO/KCXP/KRTS/KMEV. SNYDER/20  
 

 
   
REV WATCHES/WARNINGS/ADVISORIES
 
 
NV...NONE.  
CA...NONE.
