WEATHER PATTERN OVERVIEW: SKIES REMAIN FAIRLY HAZY AND SMOKY DUE
TO THE ACTIVE WILDFIRES ACROSS THE WESTERN UNITED STATES. LOOK FOR
THE SMOKE TO CONTINUE THROUGH THE OVERNIGHT WITH MINOR IMPACTS TO
VISIBILITY AND AIR QUALITY. WINDS WILL BE ON THE LIGHT SIDE WITH
OVERNIGHT LOWS IN THE 50S. NO PRECIPITATION IS EXPECTED.
WEDNESDAY THROUGH FRIDAY, THE MAIN STORY CONTINUES TO BE THE
WARMING TEMPERATURES THROUGH THE MID-WEEK PERIOD. THIS IS DUE TO A
FAIRLY STRONG UPPER LEVEL RIDGE THAT WILL UNDERGO SOME
STRENGTHENING AS IT RETROGRADES WEST IN THE COMING DAY OR TWO. AS
A RESULT, HIGH TEMPERATURES WILL CLIMB BACK INTO THE TRIPLE DIGITS
IN SOME LOCALES ON WEDNESDAY WITH AN EXPANSION OF THOSE TRIPLE
DIGIT READINGS TO MANY LOCATIONS ON THURSDAY. SOME RECORD
TEMPERATURES ARE SURE TO BE BROKEN DURING THE UPCOMING HEATWAVE.
DUE TO THE INTENSITY AND DURATION OF THE HEAT, HAVE ISSUED EXTREME
HEAT WATCHES FOR ALL OF NORTHERN AND CENTRAL NEVADA FROM THURSDAY
AFTERNOON TO SUNDAY EVENING. HIGH TEMPERATURES WILL BE IN THE 90S
WEDNESDAY AFTERNOON, RISING INTO THE UPPER 90S TO LOW 100S ON
THURSDAY AND FRIDAY. OVERNIGHT LOW TEMPERATURES WILL BE IN THE 50S
AND 60S FOR THE PERIOD. WINDS WILL GENERALLY REMAIN LIGHT THOUGH
SOME OCCASIONAL GUSTS TO 20 MPH ARE EXPECTED IN THE AFTERNOON.
SATURDAY AND SUNDAY, THE HEAT IS EXPECTED TO CONTINUE INTO THE
UPCOMING WEEKEND, THOUGH MODEL SIMULATIONS ARE SHOWING SLIGHT
INCREASES IN MID-LEVEL MOISTURE. AS THE UPPER RIDGE SHIFTS EAST
TO THE FOUR-CORNERS REGION, LOOK FOR THIS MOISTURE TO SLOWLY MAKE
ITS WAY INTO CENTRAL NEVADA. A LOW PROBABILITY OF ISOLATED DRY
THUNDERSTORMS CONTINUES ACROSS PORTIONS OF CENTRAL NEVADA THROUGH
THE WEEKEND. CONFIDENCE REMAINS LOW ON THE TIMING AND COVERAGE OF
STORMS AND MAY COMPLICATE CURRENT FIRE FIGHTING EFFORTS IN CENTRAL
NEVADA. THIS SCENARIO WILL NEED TO BE WATCHED FOR POSSIBLE
HEADLINE FIRE WEATHER PRODUCTS. AFTERNOON HIGH TEMPERATURES WILL
CONTINUE TO BE HOT WITH READINGS IN THE UPPER 90S TO LOW 100S.
OVERNIGHT LOWS WILL BE IN THE 50S AND 60S. ONE ADDITIONAL AREA OF
CONCERN FIRE WEATHER WISE IS ACROSS NORTHERN NEVADA, WHERE BREEZY
WINDS WILL COMBINE WITH LOW RELATIVE HUMIDITY VALUES TO BRING
ELEVATED FIRE WEATHER CONDITIONS. WHILE WIND SPEEDS ARE SLIGHTLY
BELOW RFW CRITERIA AT THIS TIME, FUTURE MODEL RUNS WILL NEED TO BE
SCRUTINIZED FOR FIRE WEATHER PRODUCT POTENTIAL.
MONDAY CONTINUES TO LOOK WARM ACROSS THE NORTH WITH READINGS IN
THE UPPER 90S TO LOW 100S REMAINING, THOUGH SLIGHTLY COOLER
TEMPERATURES IN THE LOW TO MID 90S MAY BRING SOME RELIEF TO THE
HOT TEMPERATURES FOR CENTRAL NEVADA.
FORECAST CONFIDENCE & DEVIATIONS: HIGH CONFIDENCE EXISTS IN
CONTINUED SMOKY CONDITIONS AFFECTING THE AREA THROUGH THE NEAR
TERM. HIGH CONFIDENCE ALSO CONTINUES WITH HOT TEMPERATURES
RETURNING FOR THE MID-WEEK PERIOD, PROMPTING AN EXTREME HEAT
WATCH FOR ALL LOCATIONS FROM THURSDAY THROUGH THE WEEKEND.
MODERATE CONFIDENCE EXISTS FOR ELEVATED FIRE WEATHER CONDITIONS
ACROSS NORTHERN NV LATE THIS WEEK. LOW CONFIDENCE IN THE TIMING
AND PLACEMENT FOR ISOLATED DRY THUNDERSTORMS CONTINUE FOR THE
WEEKEND PERIOD ACROSS CENTRAL NEVADA. GRID EDITS WERE NOT NEEDED
FOR NBM OUTPUT AT THIS TIME.
AVIATION
AREAS OF SMOKE FROM AREA WILDFIRES WILL CREATE
MOMENTARY REDUCTIONS OF MVFR/IFR CONDITIONS AT ALL TERMINALS
THROUGH TOMORROW. OTHERWISE, VFR CONDITIONS ARE FORECAST, WITH NO
PRECIPITATION EXPECTED THROUGH THE UPCOMING 24-HOUR PERIOD.
FIRE WEATHER
A FAIRLY EXPANSIVE UPPER LEVEL HIGH PRESSURE SYSTEM WILL BRING
OCCASIONAL AFTERNOON BREEZES TO ARE EXPECTED ACROSS ALL FIRE
WEATHER ZONES TODAY. ELEVATED WESTERLY FLOW ACROSS FIRE WEATHER
ZONES 437/424/438/469/470 FRIDAY AND THIS WEEKEND ARE CLOSELY
BEING WATCHED. CURRENTLY WIND SPEEDS FALL BELOW RED FLAG CRITERIA
BUT SHOULD THOSE INCREASE, THE COMBINATION OF INCREASED SPEEDS
WITH ANTECEDENT DRY, HOT CONDITIONS WILL WARRANT RFW PRODUCTS FOR
THOSE ZONES. IN ADDITION, MID-LEVEL MOISTURE CONTINUES TO SHOW A
SLOW INCREASE FOR THE UPCOMING WEEKEND. BY SUNDAY, A LOW
PROBABILITY FOR ISOLATED DRY THUNDERSTORMS EXISTS FOR ZONES
425/426/427.
