DISCUSSION
THE AXIS OF A WEAK RIDGE WILL BE MOVING OVERHEAD TODAY, ALLOWING
OUR REGION TO STAY DRY AND PARTLY CLOUDY. THIS RIDGE WILL HANG
AROUND FOR ANOTHER DAY OR SO, UNTIL IT STARTS TO BREAKDOWN AND A
TROUGH PUSHES ITS WAY IN. TEMPERATURES TODAY AND WEDNESDAY WILL
TOP OUT IN THE MID 70S FOR NE CA AND W NV VALLEYS AND MID 60S FOR
SIERRA VALLEYS. TYPICAL AFTERNOON GUSTS UP TO 25 MPH OUT OF THE
WEST WILL ALSO BE AROUND THROUGH WEDNESDAY.
AS THAT TROUGH APPROACHES THE WEST COAST WEDNESDAY AFTERNOON,
THERE'S ABOUT A 20-30% CHANCE OF SHOWERS (10% CHANCE OF LIGHTNING)
ALONG THE SIERRA CREST FROM TAHOE NORTHWARD, INTO NE CA AND N
WASHOE COUNTY. SOME CAMS ARE ALSO SHOWING SOME SHOWERS POPPING UP
IN MONO COUNTY AND MOVING NORTHEAST THROUGHOUT THE EVENING INTO
MINERAL COUNTY, BUT THOSE CHANCES ARE LESS THAN 20%. THE
POSITIONING OF THE LOW OFF THE COAST PUTS NE CA RIGHT UNDER AN
AREA OF UPPER LEVEL DIFFLUENCE, AIDING THE DEVELOPMENT OF SHOWERS
AND THUNDERSTORMS. RIGHT NOW THE CAMS ARE SHOWING ANYWHERE FROM
200-600 J/KG OF MUCAPE AND 20-30 KT 0-6KM BULK SHEAR, JUST ENOUGH
OF THE RIGHT INGREDIENTS TO PRODUCE A COUPLE NON-SEVERE
THUNDERSTORMS.
COVERAGE AND PROBABILITIES INCREASE THURSDAY (25-40%) FOR THE
SAME AREAS. FRIDAY, COVERAGE INCREASES TO THE WHOLE SIERRA CREST
FROM MONO COUNTY UP TO LASSEN COUNTY. FRIDAY CURRENTLY HAS THE
HIGHEST CHANCE (60-80%) FOR THE SIERRA FRONT (RENO, CARSON,
MINDEN) TO SEE SHOWERS AND THUNDERSTORMS (15-25% CHANCE
LIGHTNING), ALTHOUGH SATURDAY MAY ALSO HAVE EQUAL CHANCES. THIS
FAR OUT IT'S STILL A LITTLE TOO UNCERTAIN TO TELL. TEMPERATURES
WILL TAKE A HIT LATER THIS WEEK AS WELL, WITH HIGH TEMPERATURES
DIPPING DOWN INTO THE UPPER 50S FOR W NV VALLEYS AND UPPER 40S FOR
SIERRA VALLEYS BY SUNDAY. WE'LL KNOW MORE AS WE GET LATER IN THE
WEEK, BUT AT IT STANDS RIGHT NOW, EXPECT A STORMY PATTERN THROUGH
SUNDAY.

AVIATION
VFR CONDITIONS ARE EXPECTED ONCE AGAIN FOR ALL AREA TAF SITES
TODAY. DRY CONDITIONS PERSIST TODAY WITH KRNO/KCXP/KMEV/KMMH
SEEING AFTERNOON GUSTS UP TO AROUND 15-20 KTS.
AN APPROACHING PACIFIC LOW CHANGES THE WEATHER PATTERN ON
WEDNESDAY CAUSING RAIN AND ISOLATED THUNDERSTORM CHANCES (20-30%)
IN NE CA AND FAR NW NV. THE PRECIPITATION CHANCES THEN INCREASE
AND BECOME MORE WIDESPREAD ALONG THE SIERRA CREST AND INTO THE
SIERRA FRONT THROUGH THE REMAINDER OF THE WEEK. ISOLATED TO
SCATTERED THUNDERSTORMS ARE POSSIBLE THURSDAY AND FRIDAY ALONG
WITH POTENTIAL SIERRA SNOW SHOWERS GOING INTO THE WEEKEND.
