DISCUSSION
A LOW PRESSURE TROUGH ALONG THE WEST COAST WILL BRING DRIER AIR
AND INCREASED AFTERNOON BREEZES TODAY AND WEDNESDAY, JUST A TOUCH
ABOVE OUR TYPICAL ZEPHYR WINDS (GUSTING 25-30 MPH, LOCALLY UP TO
35 MPH). WITH THE DRY CONDITIONS AND WARM TEMPERATURES (HIGHS IN
THE MID-UPPER 90S FOR LOWER ELEVATIONS AND LOWER-MID 80S FOR
SIERRA COMMUNITIES), EXPECT POCKETS OF ELEVATED TO BRIEF CRITICAL
FIRE WEATHER CONCERNS. WINDS EASE BACK A BIT ON THURSDAY AS THE
TROUGH WEAKENS, BUT SIMILAR WARM AND DRY CONDITIONS WILL PERSIST,
WITH POOR OVERNIGHT HUMIDITY RECOVERY ACROSS MUCH OF WESTERN NV
AND MIDSLOPE/THERMAL BELT AREAS.
WE'LL SEE A FURTHER WARMUP FRIDAY-SATURDAY AS A HIGH PRESSURE
RIDGE EXPANDS OVER THE SOUTHWEST US AND FOUR CORNERS REGION. THIS
TRANSLATES TO HIGHS NEAR OR ABOVE 100 DEGREES FOR WESTERN NV
VALLEYS, AND UPPER 80S FOR SIERRA COMMUNITIES. AS OF NOW, THE RENO
AIRPORT HAS A 40-50% CHANCE FOR REACHING 100F ON FRIDAY, AND
70-80% CHANCE ON SATURDAY. LOWER ELEVATIONS CAN EXPECT WIDESPREAD
MODERATE HEATRISK AND ISOLATED AREAS OF MAJOR HEATRISK, SO IF
YOU HAVE OUTDOOR PLANS, BE SURE TO STAY HYDRATED AND TAKE PLENTY
OF BREAKS IN THE SHADE.
FOR LATER THIS WEEKEND INTO EARLY NEXT WEEK, THE HIGH PRESSURE
RIDGE IS PROJECTED TO SHIFT TO THE ROCKIES AND CENTRAL US, WHILE A
SOUTHERLY FLOW ALOFT OVER CA-NV BRINGS AN INCREASE OF SUBTROPICAL
MONSOON-TYPE MOISTURE AND INSTABILITY. ISOLATED PM SHOWERS AND
T-STORMS MAY RETURN AS EARLY AS SUNDAY NEAR THE EASTERN SIERRA,
WITH INCREASED POTENTIAL EXPANDING INTO PARTS OF WESTERN NV AND
NORTHEAST CA FOR EARLY NEXT WEEK. DAYTIME HIGHS SUNDAY ARE
PROJECTED TO DIP SLIGHTLY TO THE UPPER 90S FOR LOWER ELEVATIONS
WITH MID 80S NEAR THE SIERRA, THEN COULD FALL FURTHER NEXT MONDAY-
TUESDAY AS CLOUD COVER AND PRECIP CHANCES INCREASE. MJD
AVIATION

SW-W BREEZES FOR ALL TERMINALS MAINLY BETWEEN 21-04Z FOR THE NEXT
FEW DAYS, WITH GUSTS MAINLY 20-25 KT. THE WESTERN NV TERMINALS
AND KMMH COULD SEE BRIEF GUSTS NEAR 30 KT TODAY AND WEDNESDAY. MJD
