AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
331 AM PDT THU JUL 2 2020
SYNOPSIS
AVERAGE SUMMER TEMPERATURES WILL CONTINUE THROUGH INDEPENDENCE DAY
WEEKEND. AFTERNOON AND EVENING BREEZES ARE EXPECTED THIS WEEK
WITH SLIGHTLY INCREASED WINDS POSSIBLE EARLY NEXT WEEK. NO
APPRECIABLE PRECIPITATION IS FORECAST OVER THE NEXT WEEK.
DISCUSSION
NO MAJOR CHANGERS WERE MADE TO THE PREVIOUS FORECAST. THE REGION
WILL REMAIN UNDER A SOUTHWEST FLOW REGIME WHICH WILL PROMOTE
CONTINUED DRY CONDITIONS, TEMPERATURES AROUND TO SLIGHTLY ABOVE
SEASONAL AVERAGES, AND CURING OF FUELS ABOVE VALLEY FLOORS.
IN GENERAL, AFTERNOON BREEZES WILL BE FAIRLY TYPICAL, GUSTING
20-30 MPH. THESE SPEEDS COMBINED WITH LOW RH AND STEADILY CURING
FUELS WILL RAISE SOME CONCERNS HEADING INTO THE INDEPENDENCE DAY
WEEKEND. IT WOULD BE PRUDENT TO SUSPEND ACTIVITIES THAT WOULD
CAUSE A SPARK NEAR DRY VEGETATION.
ADDITIONALLY, THERE IS A WEAK 700MB TROUGH SWINGING ALONG THE
OREGON BORDER SUNDAY WHICH COULD INCREASE AFTERNOON WIND SPEEDS
MARGINALLY ALONG THE SIERRA FRONT AND MORE CONSISTENTLY CLOSER TO
THE OREGON BORDER; GUSTS AROUND 30 MPH AND UP TO 35 MPH CLOSER TO
THE OREGON BORDER. A MORE CONSOLIDATED 700/500MB TROUGH IS
EXPECTED TO DIP INTO FAR NORTHERN NEVADA LATER ON TUESDAY AND
COULD BUMP AFTERNOON GUSTS TO AROUND 35 MPH IN THE AFTERNOON FOR
PORTIONS OF NORTHERN NEVADA. THERE WOULD BE SOME FIRE WEATHER
CONCERNS WITH GUSTS TO 35 MPH EARLY NEXT WEEK.
OTHERWISE, THERE COULD BE A FEW CUMULUS BUILDUPS IN THE VICINITY
OF THE SWEETWATERS THIS AFTERNOON. CHANCES OF A SHOWER WERE
BUMPED UP FROM RIGHT AT 5% TO 5-10% FOR TODAY. AFTER TODAY
CONDITIONS REMAIN DRY WITH LITTLE CHANCE OF PRECIPITATION. IT'S
TOO SOON TO TELL WITH MUCH CERTAINTY, BUT THERE COULD BE A FEW
SHOWERS AND POSSIBLY A THUNDERSTORM OR TWO ASSOCIATED WITH THE
TUESDAY SHORTWAVE. BEST CHANCES FOR A SHOWER/STORM WOULD BE NORTH
OF A SUSANVILLE TO GERLACH LINE IF THE WAVE CAN PICK UP SOME
MOISTURE ADVECTION. BOYD
AVIATION
VFR CONDITIONS WILL PERSIST FOR THE REGION WITH TYPICAL AFTERNOON
ZEPHYRS, GUSTS AROUND 25KTS, THROUGH SATURDAY. SOME SFC GUSTS TO
30KTS BECOME MORE LIKELY SUNDAY-TUESDAY MAINLY NORTH OF HIGHWAY 50
WITH A COUPLE OF TROUGHS MOVING THROUGH FAR NORTHERN NEVADA. NO
LARGE SCALE PRECIPITATION/THUNDERSTORMS ARE FORECAST, BUT A FEW
CUMULUS BUILDUPS WILL BE POSSIBLE IN THE VICINITY OF THE
SWEETWATERS AND NORTHERN LASSEN COUNTY TODAY. BOYD
