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.
