WEATHER PATTERN OVERVIEW: A LARGE DOME OF HIGH PRESSURE CONTINUES
TO GRIP THE SW CONUS KEEPING HIGH TEMPERATURES WELL ABOVE NORMAL.
AFTERNOON HIGHS 10-15 DEGREES ABOVE NORMAL HAVE PROMPTED AN
EXTREME HEAT WATCH FOR THE REGION BEGINNING THURSDAY AND LASTING
AT LEAST THROUGH THE WEEKEND. TIME OUTDOORS SHOULD BE LIMITED FOR
BOTH PEOPLE AND ANIMALS. THOSE THAT WORK OUTSIDE SHOULD PRIORITIZE
HYDRATION.
SMOKE FROM AREA WILDFIRES CONTINUES TO PLAGUE THE AREA WITH
HAMPERED VISIBILITY AND LOW AIR QUALITY. THOSE WITH RESPIRATORY
ISSUES SHOULD AVOID TIME OUTDOORS. SMOKE IS EXPECTED TO REMAIN IN
THE FORECAST IN THE SHORT TERM UNDER HIGH PRESSURE AND LIGHT
WINDS.
A SLIGHTLY TIGHTER PRESSURE GRADIENT IN ZONAL FLOW JUST NORTH OF
THE SILVER STATE WILL INCREASE WESTERLY WIND SPEEDS ACROSS THE
NORTHERN BORDER LATER THIS WEEK. AFTERNOON BREEZES COMBINED WITH
VERY LOW RH VALUES AND EXTREME HEAT WILL CREATE ELEVATED FIRE
WEATHER CONDITIONS ACROSS NORTHERN NV.
FRIDAY AND SATURDAY THE POSITIONING OF THE SURFACE HIGH WILL
MEANDER EASTWARD INTO THE REGION OF THE FOUR CORNERS. THIS WILL
OPEN CENTRAL AND SOUTHERN NV UP SOMEWHAT TO MONSOONAL FLOW.
CURRENT GUIDANCE HAS WESTERN AZ AND THE BAJA BEING THE MAIN SOURCE
REGIONS FOR MOISTURE. WHILE PW VALUES AREN'T SPECTACULAR (0.7-0.9
INCHES) THE THREAT OF CONVECTION WILL RETURN TO NORTHERN PORTIONS
OF NYE AND SOUTHERN WHITE PINE COUNTIES POSSIBLY AS SOON AS
SATURDAY. DIURNAL FORCING AND SUFFICIENT INSTABILITY MAKE THE
THREAT OF MORE DRY THAN WET CONVECTION A POSSIBILITY THOUGH
CURRENT PROBABILITIES FOR STORM ACTIVITY REMAIN LOW.
FORECAST CONFIDENCE & DEVIATIONS: HIGH CONFIDENCE CONTINUES FOR
EXTREME HEAT AND SMOKE THROUGH THE REMAINDER OF THE WEEK. MODERATE
CONFIDENCE EXISTS IN ELEVATED FIRE WEATHER CONDITIONS ACROSS
NORTHERN NV. LOW CONFIDENCE REMAINS IN DRY STORM ACTIVITY OVER NYE
AND WHITE PINE COUNTIES THIS WEEKEND. NO MAJOR CHANGES NEEDED FOR
GRIDS AT THIS TIME.
AVIATION
VFR CONDITIONS ARE EXPECTED AT ALL TERMINALS THROUGH THURSDAY
AFTERNOON WITH NO PRECIPITATION FORECASTED. WEDNESDAY AFTERNOON
WIND GUSTS OF 18-20KTS AT KWMC, KEKO, KELY, AND KTPH WILL DIMINISH
AFTER SUNSET WEDNESDAY EVENING.
FIRE WEATHER
FAIRLY BENIGN FIRE WEATHER CONDITIONS CONTINUE THROUGH MID WEEK
ACROSS ALL FIRE WEATHER ZONES THANKS TO LIGHT WINDS. ELEVATED
CONDITIONS ARE POSSIBLE STARTING THURSDAY THROUGH THE WEEKEND FOR
NORTHERN NV FIRE ZONES DUE TO STRONGER SUSTAINED WINDS ALONG THE
NORTHERN NV BORDER. A LOW CHANCE OF DRY THUNDERSTORM ACTIVITY IS
POSSIBLE FOR FIRE WEATHER ZONES 425/426/470 THIS WEEKEND.
