.PREVIOUS DISCUSSION...
A VERY BRIEF RESPITE BETWEEN SHORT WAVE TROUGHS IS OVER THE REGION
EARLY THIS MORNING. WARM ADVECTION SHOWERS ARE ALREADY SPREADING
THROUGH NORTHERN CALIFORNIA AHEAD OF THE NEXT SHORT WAVE WEST OF THE
OREGON AND CALIFORNIA BORDER. IT LOOKS LIKE EVEN THE 06Z MODELS ARE
HAVING DIFFICULTY HANDLING THE RAPIDLY MOVING AND INTENSIFYING
SYSTEM OFF THE COAST. IT APPEARS THE CLOSEST MATCH IS WITH THE
GFS...WHICH AT LEAST HAS A CLOSED UPPER LOW DEVELOPING BY 12Z.
WITH PRECIPITATION ALONG THE RAPIDLY MOVING COLD FRONT SLAMMING INTO
THE SIERRA BY EARLY AFTERNOON (INCREASING THE CROSS SIERRA PRESSURE
GRADIENT)...ALONG WITH 50 KNOTS OF 700 MB FLOW AHEAD OF THE SYSTEM
MOVING IN...WE HAVE ISSUED YET ANOTHER SET OF WIND ADVISORIES FOR
THE REGION THROUGH THIS AFTERNOON.
ONCE AGAIN IT LOOKS LIKE STRONG RAIN SHADOWING FOR WESTERN
NEVADA...ESPECIALLY FROM RENO SOUTHWARD...AS A MID LEVEL DRY SLOT
LOOKS TO MOVE OVERHEAD THIS REGION TODAY. THIS WILL MAKE FOR
SHALLOWER MOISTURE...WHICH WHEN COMBINED WITH STRONG MID LEVEL FLOW
ACROSS THE SIERRA WILL PRODUCE MAJOR RAIN SHADOWING TODAY SOUTH OF
INTERSTATE 80. FOR THE SIERRA...QPF LOOKS MEEK WITH THE RAPID
MOVEMENT OF THE SYSTEM...ALTHOUGH THE FLY IN THE OINTMENT MAY BE A
SECONDARY VORT MAX PROGGED BY THE GFS TO MOVE THROUGH TONIGHT. THIS
MAY DEVELOP SCATTERED TO NUMEROUS SNOW SHOWERS TONIGHT FOR THE
SIERRA AND PARTS OF WESTERN NEVADA.
TONIGHT THROUGH SATURDAY...THE UPPER TROUGH WILL SLOWLY ROTATE
THROUGH NEVADA AND INTO UTAH. THIS WILL LINGER SHOWER CHANCES FOR
THE REGION INTO SATURDAY. THERE COULD EVEN BE A THUNDERSTORM EAST OF
LOVELOCK SATURDAY AFTERNOON WITH THE GFS PROGGING NEGATIVE LI/S AND
LOW 30S MODIFIED TOTAL TOTALS THERE. SUNDAY...ANOTHER RIDGE MOVES IN
FOR DRY AND WARMER WEATHER. SNYDER
.LONG TERM...MONDAY THROUGH THURSDAY...
MEDIUM RANGE MODELS IN REASONABLE AGREEMENT ON HANDLING OF
PROGRESSIVE UPPER TROUGH THAT MOVES OUT OF GULF OF ALASKA TUESDAY
AND ACROSS THE CWA TUESDAY NIGHT AND WEDNESDAY. THE
GFS...CANADIAN...AND ECMWF MODELS VERY SIMILAR IN TIMING WHILE THE
UKMET IS FASTER MOVING THE SYSTEM THROUGH THE AREA. HAVE BUMPED POPS
UP TO AT LEAST SLIGHT CHANCE TUESDAY NIGHT TO ACCOUNT FOR RECENT
TENDENCY OF MODELS TO BE TOO WEAK WITH SYSTEMS. SNOW LEVELS WILL BE
AT OR A LITTLE ABOVE VALLEY FLOORS TUESDAY NIGHT/WEDNESDAY MORNING.
BREEZY TO WINDY CONDITIONS DEVELOP AHEAD OF THE APPROACHING SYSTEM
ON TUESDAY. TROUGH MOVES ACROSS NEVADA WEDNESDAY AND INTO THE
ROCKIES LATE THURSDAY WITH A NORTHWEST FLOW REMAINING OVER NEVADA. RC
