DISCUSSION
PERSISTENT EASTERN PACIFIC TROUGHING WILL FINALLY DISLODGE AND
TRAVERSE ACROSS THE PACIFIC NORTHWEST STATES TODAY WITH AN
ATTENDANT WEAK SURFACE FRONT ENTERING AND STALLING NEAR/JUST
SOUTH OF THE OREGON BORDER. THESE FEATURES WILL ENCOURAGE ANOTHER
AFTERNOON OF BREEZY WINDS WITH W/NW GUSTS REACHING 20-30 MPH,
BROADLY. HOWEVER, A SWATH OF 25-35 MPH GUSTS AND RH REDUCTIONS TO
7-15% WILL SUPPORT ELEVATED TO BRIEFLY CRITICAL FIRE WEATHER THIS
AFTERNOON FROM THE OREGON BORDER SOUTH ALONG THE SIERRA FRONT.
BREEZY WINDS WILL ALSO MAKE FOR MORE HAZARDOUS BOATING CONDITIONS
DUE TO CHOPPY LAKE WATERS -- MOST NOTABLY ON PYRAMID LAKE.
OTHERWISE, ANOTHER VERY WARM AND DRY JULY DAY IS IN STORE TODAY.
FOR THE REST OF THE WEEK AND WEEKEND, THE REGION WILL BE
POSITIONED BETWEEN DEEPENING LOW PRESSURE TO THE NORTHWEST AND
EXPANDING HIGH PRESSURE TO THE SOUTHEAST. TEMPERATURES SLOWLY
INCREASE THROUGH SATURDAY IN RESPONSE, CULMINATING IN DAYTIME
HIGHS IN THE MID-UPPER 80S IN THE SIERRA AND UPPER 90S TO TRIPLE
DIGITS FOR LOWER ELEVATION VALLEYS ON SATURDAY. MOREOVER,
NIGHTTIME LOWS WILL STAY ON THE WARMER SIDE IN WESTERN NEVADA
VALLEYS OVER THE WEEKEND AS TEMPERATURES ONLY FALL INTO THE 60S.
THESE TEMPERATURES WILL YIELD MINOR TO MODERATE HEATRISK FRIDAY
THROUGH THE WEEKEND WITH MAJOR HEATRISK SPREADING INTO LOWEST W NV
VALLEYS ON SATURDAY. FRIDAY AND SATURDAY AFTERNOONS WILL ALSO
FEATURE INCREASED BREEZES ACROSS FAR NE CALIFORNIA AND NW NEVADA,
RENEWING FIRE AND RECREATION CONCERNS IN THESE AREAS.
WITH TIME, HIGH PRESSURE WILL CONTINUE TO BROADEN ACROSS THE
CENTRAL CONUS, ALLOWING SOUTH TO SOUTHEAST FLOW TO ADVECT
MONSOONAL MOISTURE TOWARDS THE REGION. HIGHER QUALITY MOISTURE
ALOFT AND TYPICAL JULY HEAT SHOULD INCREASE THE POTENTIAL OF
SHOWERS AND THUNDERSTORMS EARLY NEXT WEEK, BUT THERE ARE STILL
SOME QUESTIONS ON THE LOCATION OF THE MOISTURE AXIS AND DURATION
OF THE MONSOONAL PATTERN. STILL, IT'S BECOMING INCREASINGLY LIKELY
THAT SHOWERS AND THUNDERSTORMS WILL RETURN NEXT WEEK, SO BE SURE
TO CHECK BACK WITH THE LATEST FORECAST AND MAKE PLANS ACCORDINGLY.
