DISCUSSION
TEMPERATURES WILL CONTINUE TO RAMP UP SLOWLY FOR THE NEXT COUPLE
OF DAYS, PEAKING FRIDAY AND SATURDAY AS HIGHS REACH OR SURPASS 100
DEGREES FOR MOST LOWER ELEVATIONS OF WESTERN NV/NORTHEAST
CA/CHALFANT VALLEY, AND NEAR 90 FOR SIERRA COMMUNITIES. IN MOST
AREAS, THE DRY AIR MASS WILL ALLOW FOR DECENT COOLING INTO THE
UPPER 50S-LOWER 60S FOR MOST LOWER VALLEYS, BUT ALONG US-95 IN
MINERAL COUNTY THE NIGHTS THIS WEEKEND LOOK WARMER, WITH LOWS NEAR
OR ABOVE 70 DEGREES WITH HEATRISK EDGING INTO THE MAJOR CATEGORY.
THEREFORE WE HAVE ISSUED A HEAT ADVISORY FOR MINERAL/SOUTHERN LYON
COUNTIES.
WHILE CLEAR SKIES ARE EXPECTED TO PREVAIL FOR THE NEXT FEW DAYS,
AREAS OF HAZE WILL LIKELY CONTINUE DUE TO LARGE FIRES BURNING IN
OREGON WITH WINDS CARRYING SMOKE ALOFT ACROSS MOST OF NORTHWEST-
WEST CENTRAL NV, AND A SMALL PORTION OF NORTHEAST CA. IN ADDITION,
DAILY FLARE UPS WITHIN THE INTERIOR OF THE ELEPHANT FIRE WILL
PRODUCE PATCHY SMOKE AND SHORT PERIODS OF REDUCED AIR QUALITY EAST
OF THIS FIRE INTO RENO'S NORTH VALLEYS DURING THE AFTERNOON-EARLY
EVENING THROUGH AT LEAST THURSDAY.
TYPICAL AFTERNOON SW-W BREEZES WITH GUSTS NEAR 25 MPH, LOCALLY UP
TO 30 MPH ARE EXPECTED FOR FAR NORTHEAST CA/NORTHWEST AND FAR
WESTERN NV THROUGH THURSDAY, THEN LIGHTER WINDS RETURN FRIDAY. FOR
SATURDAY, WINDS COULD EDGE UP A BIT (CLOSER TO 30 MPH) AS A
SHORTWAVE PASSAGE IN THE NORTHWEST US BRUSHES ACROSS OUR REGION.
THIS WOULD PRODUCE SHORT PERIODS OF ELEVATED FIRE WEATHER
CONCERNS SATURDAY AFTERNOON.
OTHERWISE, BEHIND THIS SHORTWAVE PASSAGE, TEMPERATURES EASE BACK
SLIGHTLY SUNDAY-MONDAY BUT REMAIN PLENTY WARM FOR THE START OF
AUGUST. BLENDED GUIDANCE THEN FAVORS MORE TRIPLE DIGIT HEAT
RETURNING TO LOWER ELEVATIONS TOWARD THE MIDDLE OF NEXT WEEK,
ALTHOUGH CONFIDENCE ISN'T AS HIGH DUE TO SOME DIVERGING SCENARIOS,
SOME OF WHICH KEEP THE HIGH PRESSURE RIDGE SUPPRESSED FARTHER TO
THE SOUTH WHICH WOULD FAVOR HIGHS REMAINING IN THE 90S. HOWEVER,
CONFIDENCE IS HIGHER FOR DRY CONDITIONS AND TYPICAL AFTERNOON
BREEZES CONTINUING THROUGH AT LEAST THE MIDDLE OF NEXT WEEK. MJD
AVIATION
VFR CONDITIONS PREVAIL THROUGH THE UPCOMING WEEK WITH LITTLE TO
NO CLOUD COVER. HOWEVER, HAZY SKIES FROM WILDFIRES ACROSS THE
WESTERN US COULD BRING MINOR REDUCTIONS IN SLANTWISE VISIBILITY.
SW-W WIND GUSTS 20-25 KT EACH AFTERNOON (MAINLY 21-04Z) THROUGH
THURSDAY AT THE MAIN TERMINALS, THEN LIGHTER ON FRIDAY. MJD
