AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
319 AM PDT THU MAR 29 2012

.SHORT TERM...
RAISED POP (ESPECIALLY IN THE SIERRA) SATURDAY NIGHT AND HOISTED
WIND/WINTER WATCHES FOR EASTERN CALIFORNIA AND FAR WESTERN NEVADA
FOR LATE FRIDAY NIGHT THROUGH SATURDAY NIGHT.

THE PATTERN THROUGH FRIDAY WILL FEATURE A FLAT UPPER RIDGE OVER
THE REGION WITH A MODEST PACIFIC MOISTURE TAP AIMED AT FAR
NORTHWEST CALIFORNIA AND SOUTHWEST OREGON. THE FAR NORTHERN AND
NORTHWESTERN CWA WILL BE ON THE EDGE OF THE FEED WITH SOME LIGHT
WARM AIR ADVECTION PRECIPITATION POSSIBLE THROUGH FRIDAY. FURTHER
SOUTH, A SOLID WARM UP WILL BEGIN TODAY WITH TEMPS MAXIMIZING ON
FRIDAY AT 8-15 DEGREES ABOVE AVERAGE AS THE RIDGE PUMPS UP A BIT
MORE AS ENERGY OVER THE EASTERN PACIFIC BUCKLES THE FLOW.

NOW LET'S MOVE ON TO THE MAIN DISCUSSION POINT IN THE SHORT TERM
THAT IS THE STRONG SYSTEM FOR SATURDAY. THERE WILL BE SNOWFALL,
SNOW LEVEL, AND WIND ISSUES WITH THE SYSTEM BUT LET'S START WITH
THE WIND POTENTIAL FOR LATE FRIDAY NIGHT AND SATURDAY. THE 00Z GEFS
ANOMALIES FOR SURFACE PRESSURES AND 700 MB WINDS ARE RANGING AROUND
3 TO 3.5 STANDARD DEVIATIONS FOR EARLY SATURDAY MORNING. MODEL SURFACE
PRESSURES BOTTOM OUT AROUND 985 MB OFF THE FAR NORTHWEST CALIFORNIA
COAST AS A 135-150 KT JET SLAMS INTO THE NORTHERN CALIFORNIA COAST
SATURDAY MORNING. AS THE LOW DEVELOPS, VALLEY WINDS ARE LIKELY TO
BACK TO SOUTHERLY LATE FRIDAY NIGHT. THIS WILL PUT NORTH TO SOUTH
FACING VALLEYS OF FAR WESTERN NEVADA AND EASTERN CALIFORNIA IN
THE BEST POSITION TO GET STRONG WINDS AHEAD OF THE COLD FRONT DUE
IN AROUND MIDDAY SATURDAY.

AS WINDS ALOFT BACK TO A MORE SOUTHERLY DIRECTION, THIS DOES NOT
LOOK LIKE A MAJOR DOWNSLOPE SITUATION AS WINDS NEED TO BE MORE
PERPENDICULAR TO THE SIERRA TO GET EFFICIENT DOWNSLOPING. HOWEVER,
THE GRADIENT OVER THE REGION LOOKS TO BE QUITE STOUT SO SUSTAINED
WINDS COULD GET QUITE STRONG LATE FRIDAY NIGHT AND SATURDAY
MORNING. IN FACT, THE CURRENT PROGS LOOK SIMILAR TO A HIGH WIND
EVENT BACK IN NOVEMBER, 2009.

WITH ALL THIS IN MIND, WE HAVE HOISTED A HIGH WIND WATCH FOR MONO
COUNTY UP THROUGH FAR WESTERN NEVADA AND THE SURPRISE VALLEY OF
EASTERN MODOC COUNTY. STRONG WINDS ARE ALSO QUITE POSSIBLE OVER
EASTERN LASSEN COUNTY AND INTO THE TAHOE BASIN (ESPECIALLY SOUTH
LAKE TAHOE WHERE WINDS CAN EFFICIENTLY FUNNEL OUT OF THE SOUTH).
HOWEVER, WITH HEAVY SNOWFALL POSSIBLE WITH THE COLD FRONT, WE HAVE
DECIDED TO ROLL WINDS AND SNOW INTO A WINTER STORM WATCH FOR THE
NORTHERN SIERRA AND UP INTO LASSEN COUNTY.

TURNING TO SNOWFALL POTENTIAL, WINDS ARE PROGGED TO GO MORE
SOUTHERLY THAN WESTERLY FOR THE NORTHERN SIERRA AHEAD OF THE COLD
FRONT. THIS IS MOST FAVORABLE FOR PLUMAS COUNTY TO GET STRONG
OROGRAPHIC ENHANCEMENT. MODELS SEEM TO HINT AT THIS AS THEY
DEVELOP A COLD POCKET IN THE 700 MB TEMPS FRIDAY NIGHT (INDICATIVE
OF COOLING DUE TO STRONG LIFT) TO THE NORTH OF LAKE TAHOE. THIS
STRONG FORCING COULD HOLD DOWN SNOW LEVELS MORE THAN ONE WOULD
OTHERWISE EXPECT, ESPECIALLY FROM THE TAHOE CREST UP INTO PLUMAS
AND WESTERN LASSEN COUNTIES. EITHER WAY, THE HIGHER ELEVATIONS OF
THE NORTHERN SIERRA COULD SEE A PERIOD OF MODERATE TO HEAVY
PRECIPITATION WITH THE COLD FRONT AND EVEN AFTER AS A SECONDARY
WAVE MOVES THROUGH SATURDAY EVENING WITH BETTER WESTERLY
OROGRAPHIC FLOW.

OUTSIDE OF THE SIERRA, CURRENT PROGS POINT TO AT LEAST SOME PRECIP
FOR A MAJORITY OF THE CWA AS THE FRONT LOOKS QUITE STRONG ENOUGH
TO HOLD PRECIP TOGETHER AS IT MOVES INTO THE GREAT BASIN. THEREFORE,
I HAVE UPPED POPS SOME FOR MANY BASIN AREAS ESPECIALLY BY SATURDAY
NIGHT. SNYDER

.LONG TERM...SUNDAY THROUGH WEDNESDAY...
FEW CHANGES MADE WITH AN OVERALL BREAK IN SYSTEMS FOR MOST OF THE
PERIOD. MODELS IN GOOD AGREEMENT WITH A LITTLE MORE RIDGING FOR THE
SIERRA AND WESTERN NEVADA EARLY NEXT WEEK BEFORE THE NEXT LOW
ARRIVES. MAIN CHANGE WAS TO DRY OUT ALL AREAS SUNDAY AND SUNDAY
NIGHT. SATURDAY'S SYSTEM WILL BE DEPARTING RAPIDLY WITH FLAT RIDGING
IN ITS WAKE. MOISTURE AND JET STREAM WILL BE PUSHED TO THE NORTH
KEEPING IT DRY. STILL, TEMPS WILL REMAIN BELOW NORMAL SUNDAY IN THE
WAKE OF SATURDAY'S COLD FRONT.

WITH RIDGING MON/TUES CONTINUED WITH THE DRY FORECAST FOR THE MOST
PART WITH WARMING TEMPERATURES. COULD GO BACK ABOVE NORMAL TUESDAY
AFTERNOON IF THE GFS IS RIGHT. EC IS ABOUT 12 HOURS FASTER WITH THE
NEXT WAVE ARRIVING TUES AFTERNOON WHILE GFS IS MORE WED MORNING.
WITH THE WAVE SHOWING SIGNS OF AMPLIFYING PREFER THE SLOWER GFS
SOLUTION HERE. DUE TO THE UNCERTAINTY LEFT A SLIGHT CHC OF SHOWERS
IN NORTHEAST CALIFORNIA IN CASE EC IS RIGHT.

FOR WED, IT APPEARS THE FIRST WAVE OF A DEEP EAST PACIFIC LOW WILL
AFFECT THE SIERRA. WITH MORE WAVE DROPPING DOWN THE BACK SIDE OF THE
PARENT LOW, THIS INITIAL WAVE WILL BE SHUNTED MORE NNEWD. THEREFORE
KEPT CHC POPS MAINLY IN THE SIERRA FROM TAHOE NORTHWARD WITH WRN NV
DRY EAST OF HWY 95. TEMPS WILL COOL SLIGHTLY WITH THE COLD FRONT
TRYING TO MOVE THROUGH. WALLMANN
