AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE RENO NV  
258 AM PDT WED JUN 26 2019  
   
SYNOPSIS
 
 
GUSTY WINDS CONTINUE THROUGH THURSDAY AS LOW PRESSURE STAYS PARKED  
OFF THE PACIFIC NORTHWEST COAST. THE STRONGEST WINDS ARE EXPECTED  
THIS AFTERNOON WITH BREEZY CONDITIONS ON THURSDAY. BELOW AVERAGE  
TEMPERATURES WILL BE IN PLACE INTO THE WEEKEND WITH A WARM UP BY  
SUNDAY INTO NEXT WEEK WITH TYPICAL SUMMERTIME AFTERNOON WEST TO  
SOUTHWEST WINDS.  
 

 
   
SHORT TERM
 
 
A LOW PRESSURE SYSTEM OFF THE PACIFIC NORTHWEST COAST WILL PROVIDE  
GUSTY WINDS THIS AFTERNOON WITH THE OVERALL HIGHEST WINDS EXPECTED  
TODAY IN COMPARISON TO YESTERDAY AND THURSDAY. PEAK GUSTS OF 40-45  
MPH WILL DEVELOP MAINLY FROM HIGHWAY 50 NORTHWARD, PARTICULARLY  
THROUGH THE HIGHWAY 395/I-580 CORRIDOR. GUSTY WINDS ACROSS SIERRA  
RIDGETOPS COULD REACH TO AROUND 75 MPH. GUSTS ON THURSDAY AFTERNOON  
WILL LARGELY BE IN THE 30-35 MPH RANGE.  
 
FIRE WEATHER REMAINS A CONSIDERABLE CONCERN FOR AREAS WITH DRIED  
OUT/CURED GRASSES. AS SUCH, A RED FLAG WARNING WILL BE IN EFFECT  
TODAY (SEE FIRE WEATHER SECTION). IMPACTS FOR HIGH PROFILE VEHICLES  
AND HAZARDOUS BOATING CONDITIONS ON AREA LAKES CAN BE EXPECTED WITH  
LAKE WIND ADVISORIES IN EFFECT THROUGH THURSDAY.  
 
BEGINNING FRIDAY AND INTO THE WEEKEND, THE MAIN LOW WILL MOVE INLAND  
WITH LIGHTER SOUTHWEST FLOW. TYPICAL AFTERNOON ZEPHYR WINDS WILL BE  
IN PLACE ON FRIDAY. COOLER WEATHER WILL ALSO PREVAIL HEADING INTO  
THE WEEKEND WITH HIGHS RUNNING ABOUT 7-10 DEGREES BELOW AVERAGE FOR  
LATE JUNE. HIGHS THURSDAY AND FRIDAY WILL GENERALLY BE IN THE MID TO  
UPPER 70S ACROSS WESTERN NEVADA WITH MID-60S FOR SIERRA VALLEYS.  
OVERNIGHT LOWS IN COLDER SIERRA VALLEYS WILL SEE TEMPERATURES  
SINKING TO NEAR THE FREEZING MARK BY THURSDAY NIGHT. FUENTES  
   
LONG TERM...SATURDAY THROUGH NEXT WEEK
 
 
TROUGHING REMAINS OVER THE WEST COAST THROUGH THE WEEKEND WITH  
STABLE AND DRY SOUTHWEST FLOW OVER THE SIERRA AND WESTERN NEVADA.  
TEMPERATURES WILL BE INCREASING THROUGH THE WEEKEND AND NEXT WEEK.  
WINDS COULD BECOME A LITTLE GUSTY ON SUNDAY AFTERNOON AS A SHORTWAVE  
TROUGH PASSES OVER NORTHERN CA/NV. WE WILL HAVE TO KEEP AN EYE ON  
THAT FEATURE FOR POTENTIAL CHOPPY LAKE CONDITIONS.  
 
AS THE RIDGE OVER THE GREAT BASIN CONTINUES TO STRENGTHEN, WE WILL  
SEE TEMPERATURES PUSHING BACK UP TO THE UPPER 80S AND NEAR 90 FOR  
WESTERN NEVADA AND UPPER 70S/LOW 80S IN THE SIERRA VALLEYS. NO  
THUNDERSTORMS ARE CURRENTLY IN THE FORECAST THROUGH NEXT WEEK AS THE  
FLOW ALOFT REMAINS OUT OF THE SOUTHWEST. -HOON  
 

 
   
AVIATION
 
 
 
GUSTY WINDS ARE THE MAIN CONCERN WITH VFR CONDITIONS  
CONTINUING THROUGH THURSDAY. EXPECT MTN WAVE TURBULENCE WITH LOCAL  
LLWS, ESPECIALLY AROUND LAKE TAHOE AND THE SIERRA FRONT. GUSTS TO 40  
KTS THIS AFTERNOON AND 35 KTS THURSDAY. PEAK WINDS ARE EXPECTED 19-  
02Z EACH DAY.  
 
OVERNIGHT, WINDS WILL DIMINISH AT THE TERMINALS TO AROUND 10 KTS.  
HOWEVER, WITH RIDGE WINDS CONTINUING, LLWS IS MORE LIKELY FOR  
KTRK/KTVL 03-16Z. X/HOON  
 

 
   
FIRE WEATHER
 
 
RED FLAG WARNING FOR GUSTY WINDS AND DRY CONDITIONS REMAINS IN  
EFFECT FOR ELEVATIONS BELOW 6000 FT ACROSS MUCH OF WESTERN NEVADA  
AND FAR NORTHEASTERN CALIFORNIA SOUTH OF SUSANVILLE AND EAST OF  
HIGHWAY 395. THE RED FLAG WARNING GOES INTO EFFECT FROM THIS  
AFTERNOON THROUGH THURSDAY EVENING.  
 
WIND GUSTS UP TO 45 MPH WILL BE LIKELY TODAY, EVEN STRONGER IN WIND  
PRONE AREAS. WINDS ON THURSDAY WILL BE SLIGHTLY LESS, WIND GUSTS  
AROUND 35 MPH. DURATION OF THE EVENT IS ALSO GOING TO BE AN ISSUE,  
WITH SOME TYPICALLY WINDY LOCATIONS SEEING MANY HOURS RED FLAG  
CONDITIONS TODAY AND TOMORROW.  
 
FUELS ARE NEARING CRITICAL STATUS ACROSS THE LOWER ELEVATIONS OF  
WESTERN NEVADA. ACCORDING TO OUR FIRE PARTNERS ON THE SIERRA FRONT,  
THE SAGEBRUSH IS NOT QUITE AT CRITICAL VALUES, BUT DUE TO THE  
EXPECTED STRONG GUSTY WINDS, POTENTIAL WILDFIRES WILL BE ABLE TO  
CARRY EASILY. THERE WAS A WILDLAND FIRE IN LYON COUNTY OVER THE  
WEEKEND THAT EXHIBITED SOME ACTIVE FIRE BEHAVIOR THROUGH THE GRASS  
AND PINYON-JUNIPER, WITH TORCHING AND SPOTTING EVEN IN LIGHTER  
WINDS.  
 
BOTTOM LINE--EVEN THOUGH THE VEGETATION IS STILL NOT TO PEAK FIRE  
SEASON DRYNESS, PEOPLE AROUND THE REGION SHOULD TAKE GREAT CARE TO  
NOT SPARK ANY NEW FIRES DURING THIS WIND EVENT. -HOON
