AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE ELKO NV  
306 PM PDT FRI AUG 14 2020  
   
SYNOPSIS
 
HIGH PRESSURE BUILDS INTO THE REGION, AND WILL HELP  
AFTERNOON HIGHS OVER THE WEEKEND APPROACH RECORD NUMBERS. WELL  
ABOVE AVERAGE TEMPERATURES CONTINUE THROUGH THE WORKWEEK.  
TROPICAL MOISTURE WRAPPING AROUND THE HIGH COULD TRIGGER  
THUNDERSTORMS EACH DAY, WITH MOST OF THEM BEING DRY IN NATURE.  
 

 
   
SHORT TERM
 
TODAY THROUGH MONDAY AFTERNOON  
 
BUILDING FOUR CORNERS HIGH IS ENTRENCHED ACROSS NV AND WILL STAY  
AS SUCH THROUGH THE WEEKEND. THIS WILL BRING HOT TO EXTREMELY HOT  
TEMPERATURES ACROSS NV. THE HIGH WILL BE IN THE UPPER 90S TO LOW  
100S WHICH IS FAR ABOVE NORMAL FOR THIS TIME OF YEAR. THIS HEAT IS  
EXPECTED TO APPROACH OR EVEN EXCEED RECORD VALUES. THE HEAT IS  
SUCH THAT AN EXCESSIVE HEAT WATCH IS IN EFFECT FOR THIS SUNDAY  
THROUGH TUESDAY. THIS WATCH HAS A VERY HIGH CHANCE OF BEING  
UPGRADED TO AN ADVISORY OR WARNING AS THE HEAT WAVE UNFOLDS. WINDS  
ARE ALSO EXPECTED TO BE LIGHT DURING THIS TIME SO LITTLE IN THE  
WAY OF RELIEF CAN BE FOUND IN THEM. THERE IS SOME TROPICAL  
MOISTURE ROUNDING THE AXIS OF THE HIGH WHICH IS EXPECTED TO  
PERMEATE INTO NV DURING THE WEEKEND. THIS WILL CAUSE SOME ISOLATED  
DRY THUNDERSTORMS DURING THE DAYTIME EACH DAY STARTING AS EARLY AS  
SATURDAY BUT MORE LIKELY ON SUNDAY. THESE THUNDERSTORMS WILL NOT  
RESULT IN MUCH IF ANY RAINFALL BUT CAN CAUSE GUSTY OUTFLOW WINDS.  
HAZE CAUSED BY SMOKE FROM A FEW GREAT BASIN FIRES WILL BE PRESENT,  
MOST NOTICEABLY IN THE EARLY MORNING WHEN AN INVERSION WILL BE IN  
PLACE  
 
   
LONG TERM
 
SUNDAY NIGHT THROUGH FRIDAY  
 
THE STRONG HIGH PRESSURE SYSTEM SHOULD HAVE SETTLED IN OUR  
REGION FOR A LONG DURATION STAY. THE HOTTEST TEMPERATURES ARE  
LIKELY TO BE ON MONDAY THEN COOLING SLIGHTLY ONWARD, BUT THEY ARE  
STILL EXPECTED TO BE WELL ABOVE NORMAL THROUGH THE WEEK. THE  
AVERAGE AFTERNOON HIGH THIS TIME OF YEAR IS IN THE MID 80S TO LOW  
90S. EXPECT HIGHS THROUGH THE WEEK TO BE MOSTLY IN THE UPPER 90S  
TO LOW 100S.  
 
SOME TROPICAL MOISTURE WRAPS AROUND THE HIGH PRESSURE SYSTEM IN  
THE MID-LEVELS, AND MAKE ITS WAY INTO CENTRAL NEVADA. THIS SHOULD  
LEAD TO THUNDERSTORMS EACH DAY THROUGH THE WEEK. MOST OF THEM  
SHOULD BE DRY THUNDERSTORMS, BUT WE ARENT RULING OUT ONE OR TWO  
HUNDREDTHS OF AN INCH MAKING IT TO THE GROUND IN SOME LOCATIONS.  
 

 
   
AVIATION
 
VFR AT ALL TERMINALS FOR THE NEXT 24 HOURS. THE ONLY  
EXCEPTION MAY BE KWMC WHICH COULD SEE HAZE REDUCE VISIBILITY TO  
MVFR BRIEFLY IN THE MORNING. ISOLATED THUNDERSTORMS WILL BE  
POSSIBLE IN CENTRAL NV STARTING DURING THE WEEKEND. EXTREME HIGH  
TEMPERATURES WILL PRODUCE VERY HIGH DENSITY ALTITUDE AT ALL  
TERMINALS FOR THE NEXT SEVERAL DAYS.  
 

 
   
FIRE WEATHER
 
HOT AND DRY CONDITIONS WILL OCCUR IN ALL FIRE  
ZONES THROUGH AT LEAST NEXT WEEK WITH STRONG HIGH PRESSURE IN  
PLACE IN THE WEST. THE TEMPERATURES WILL BE WELL ABOVE NORMAL AND  
MAY APPROACH OR EXCEED RECORD LEVELS. TROPICAL MOISTURE ROUNDING  
THE HIGH SHOULD PERMEATE INTO NV WHICH COULD LEAD TO AN ISOLATED  
DRY THUNDERSTORM AS EARLY AS SATURDAY IN FIRE ZONES 426, 427, AND  
WESTERN PORTIONS OF 437. ISOLATED THUNDERSTORMS SHOULD EXPAND IN  
COVERAGE A BIT EACH DAY SUNDAY THROUGH AT LEAST TUESDAY IN  
NORTHERN AND CENTRAL NEVADA, BUT IS LOOKING AT THIS TIME TO REMAIN  
ISOLATED IN NATURE. CONFIDENCE REMAINS LOW THOUGH AT THIS TIME IN  
THE THUNDERSTORM COVERAGE. AT LOT WILL DEPEND UPON THE EXACT  
LOCATION OF THE RIDGE EACH DAY AND THE AMOUNT OF TROPICAL  
MOISTURE.  
 

 
   
CLIMATE
 
MUCH ABOVE NORMAL TEMPERATURES ARE EXPECTED SATURDAY  
THROUGH AT THURSDAY ACROSS ALL OF NEVADA. HOT DAYTIME TEMPERATURES  
COUPLED WITH SOME RELATIVELY MILD TO HOT OVERNIGHT LOWS WILL  
LIKELY LEAD TO SOME FAIRLY WIDESPREAD HEAT ADVISORIES TO BE ISSUED  
DUE TO THE HIGH RISK OF HEALTH RELATED ISSUES FOR THOSE WHO ARE  
SENSITIVE TO HEAT AND/OR WITHOUT EFFECTIVE INDOOR COOLING. KEEPING  
HYDRATED IS HIGHLY RECOMMENDED. PLEASE PREPARE FOR THIS AS IT IS  
A LONGER THEN NORMAL DURATION HEAT EVENT AND SOME RECORD  
TEMPERATURES IN THE LOWER 100'S COULD BE REACHED AT TIMES.
