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
