DISCUSSION
A WEAK LOW PRESSURE TROUGH OVER CA/NV WILL GRADUALLY RETREAT TO
JUST OFF THE PACIFIC NW COAST AS WE REACH THE JULY 4TH HOLIDAY
WEEKEND. THIS WILL ALLOW FOR CONTINUED WARMING FOR THE NEXT FEW
DAYS. FROM JULY 4TH THROUGH AT LEAST EARLY NEXT WEEK, HIGHS ARE
PROJECTED TO REMAIN STEADY IN THE MID-UPPER 90S FOR MOST LOWER
ELEVATIONS AND LOWER-MID 80S FOR SIERRA COMMUNITIES--A BIT WARMER
THAN AVERAGE BUT NOT UNUSUAL FOR EARLY JULY. THE DRY AIR MASS WILL
ALLOW FOR DECENT COOLING EACH NIGHT WHICH LIMITS THE OVERALL
HEATRISK, ALTHOUGH POCKETS OF MODERATE HEATRISK RETURN TO WARMER
VALLEYS EACH AFTERNOON FROM SATURDAY ONWARD, WHEN TAKING THE USUAL
HEAT SAFETY PRECAUTIONS IS ADVISED.
EACH AFTERNOON WILL BRING TYPICAL ZEPHYR-TYPE BREEZES WITH GUSTS
NEAR 25 MPH, ALTHOUGH ON ANY AFTERNOON OCCASIONAL GUSTS AROUND 30
MPH ARE WITHIN REACH MAINLY NEAR THE US-395/I-580 CORRIDORS. WITH
THE RECENT DRY CONDITIONS ACROSS THE REGION, ANY SPARK COULD
IGNITE AND CARRY IN DRY VEGETATION, SO AVOID ACTIVITIES THAT COULD
START A FIRE, AND BE EXTRA CAUTIOUS WITH FIREWORKS FOR THE HOLIDAY
FESTIVITIES. WHILE THE OVERALL WINDS WON'T MEET LAKE WIND
ADVISORY THRESHOLDS, BE AWARE OF LOCALIZED CHOPPY CONDITIONS EACH
AFTERNOON-EVENING, WHICH COULD BE ENHANCED A BIT WITH INCREASED
WATERCRAFT USAGE ON AREA LAKES.
WHILE THERE ISN'T A SIGNIFICANT THUNDERSTORM THREAT FOR THE
UPCOMING WEEK, AS TEMPERATURES CLIMB WE'LL SEE DAILY FORMATION
OF CUMULUS EACH AFTERNOON. ANY SUBTLE WEAK UPPER DISTURBANCE
COMBINED WITH TERRAIN-DRIVEN CONVERGENCE COULD ALLOW FOR A FEW
SHORT-LIVED SHOWERS CAPABLE OF ISOLATED LIGHTNING. THIS POTENTIAL
IS MINIMAL (LESS THAN 10%) BUT NON-ZERO, BUT IF ANY SHOWERS MANAGE
TO FORM, FAVORED AREAS WOULD BE NEAR THE EASTERN SIERRA AND
ADJACENT PORTIONS OF WESTERN NV MAINLY FROM US-50 SOUTHWARD. THE
LATEST HIGH RESOLUTION MODEL GUIDANCE CONTINUES TO SHOW A MIX OF
SCENARIOS TODAY THROUGH FRIDAY, RANGING FROM JUST FLAT TO MODERATE
CUMULUS TO A FEW SHOWER/T-STORM CELLS POPPING UP BETWEEN 3-9 PM.
