AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
208 AM PDT SAT JUL 25 2015

.SYNOPSIS...

A DRIER AIR MASS WITH SEASONABLE TEMPERATURES WILL CONTINUE INTO THE
WEEKEND. TYPICAL AFTERNOON ZEPHYR BREEZES EXPECTED THE NEXT FEW DAYS
WITH STRONGER WINDS EXPECTED SUNDAY AS THE NEXT TROUGH APPROACHES.
HAZARDOUS BOATING CONDITIONS AND POSSIBLE FIRE WEATHER CONCERNS ARE
POSSIBLE ON SUNDAY AFTERNOON.

&&

.SHORT TERM...

ONLY MINOR ADJUSTMENTS IN THE SHORT TERM FORECAST WITH AN OVERALL
PLEASANT WEATHER PATTERN CONTINUING INTO EARLY NEXT WEEK. WE WILL
REMAIN IN THE UPPER 80S ACROSS MUCH OF WESTERN NEVADA THROUGH THE
WEEKEND WITH MID 70S ACROSS SIERRA VALLEYS. TYPICAL AFTERNOON ZEPHYR
BREEZES WILL PREVAIL AGAIN THIS AFTERNOON WITH GUSTS UP TO 25-30
MPH POSSIBLE BY LATE AFTERNOON.

STRONGER WIND GUSTS NEAR 30-35 MPH ARE EXPECTED BY SUNDAY AS AN
UPPER LEVEL TROUGH SWINGS ACROSS NORTHERN NEVADA SUNDAY NIGHT. DID
SLOW THE TIMING OF THE WINDS A BIT AS THE PERIOD OF HIGHER GUSTS IS
EXPECTED BY LATE AFTERNOON INTO EARLY EVENING WITH THE AXIS OF THE
HIGHEST 700MB WINDS. HAZARDOUS BOATING CONDITIONS ARE POSSIBLE BY
SUNDAY AFTERNOON ALONG WITH SOME POTENTIAL FIRE WEATHER CONCERNS.
ALTHOUGH WIDE SPREAD CRITICAL FIRE WEATHER CONDITIONS ARE NOT
EXPECTED AT THIS TIME, THERE COULD STILL BE ISOLATED AREAS WHICH
MEET RED FLAG CONDITIONS.

DID ADD A MENTION OF SHOWERS ACROSS FAR NORTHERN WASHOE COUNTY NEAR
THE OREGON BORDER AS THE TROUGH PUSHES THROUGH SUNDAY NIGHT.
ALTHOUGH DYNAMIC FORCING IS PRESENT, MOISTURE IS LIMITED AND
INSTABILITY IS VERY WEAK. AS SUCH, ANY SHOWERS THAT DO DEVELOP
WILL BE VERY LIGHT AND COULD END UP JUST AS VIRGA WITH DRY
SUBCLOUD LAYERS EVIDENT ON MODEL SOUNDINGS. WINDS THEN SHIFT
NORTHERNLY BEHIND THE TROUGH FOR MONDAY WHICH WILL RESULT IN A FEW
DEGREES OF COOLING. FUENTES


.LONG TERM...TUESDAY THROUGH FRIDAY...

ON TUESDAY, A STRONG SURFACE HIGH FOR JULY WILL CONTINUE OVER THE
GREAT BASIN WHICH WILL RESULT IN A NORTHEAST TO EAST GRADIENT IN THE
LOW LEVELS AND TEMPERATURES ONLY MODERATING SLIGHTLY UPWARD FROM
MONDAY. THIS GRADIENT WILL WEAKEN AS AN UPPER RIDGE BUILDS OVERHEAD
AND ALLOWS FOR STRONG SURFACE HEATING AND MUCH WARMER TEMPERATURES
WED-FRI. TEMPERATURES WILL PUSH 100 DEGREES IN SOME WESTERN NV
VALLEYS.

CONDITIONS WILL BE DRY AND STABLE FOR TUE-WED. BY THU-FRI, MODELS
ARE BECOMING A BIT MORE UNSTABLE AS SOUTHEAST FLOW DEVELOPS ALONG
THE SIERRA AND HELPS BRING SOME MOISTURE BACK INTO THE REGION. GIVEN
THE VERY WARM TEMPERATURES, THE POTENTIAL FOR THUNDERSTORMS IS
INCREASING. WE ADDED A SLIGHT CHANCE NEAR MAMMOTH LAKES THURSDAY AND
INCREASED POPS FOR FRIDAY, SPREADING THEM FARTHER NORTH. HOHMANN

.AVIATION...

VFR CONDITIONS ARE EXPECTED AT MAIN TERMINALS WITH TYPICAL WEST WIND
GUSTS 20-25KT TODAY MAINLY BTWN 21Z-04Z. A TROUGH PASSAGE SUNDAY
WILL ENHANCE WINDS A BIT WITH GUSTS AROUND 30KT. BOYD/HOHMANN
