AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
916 PM PDT TUE MAY 22 2012

.SHORT TERM DISCUSSION...

WE STILL HAVE MODERATE FLOW THROUGH THE DELTA AT THIS HOUR BUT IT
WILL CONTINUE TO WEAKEN AS THE OVERALL FLOW CONTINUES TO TURN
NORTHWEST OVERNIGHT.

ON WEDNESDAY THERE WILL BE A BREEZY NORTHWEST FLOW OVER THE REGION
WITH ONLY SLIGHT COOLING EXPECTED OVER THE VALLEY AND MOUNTAINS.
WINDS SHOULD GENERALLY BE IN THE 10 TO 20 MPH RANGE FOR THE DAY
FROM THE NORTHWEST BUT IN THE AFTERNOON COULD GET SLIGHTLY
STRONGER FOR A COUPLE OF HOURS. THIS SAME PATTERN CONTINUES FOR
THURSDAY WITH CONTINUED SLIGHT COOLING AND BREEZY WINDS.

BY FRIDAY A TROUGH WILL DROP DOWN FROM THE NORTH BUT AT THIS TIME
IT DOES NOT LOOK LIKE IT WILL BRING A LOT OF RAIN TO THE REGION.
MAINLY SHOWERS AND THUNDERSTORMS ARE EXPECTED AND ARE EVEN
STARTING TO LOOK MORE PROMISING IN THE VALLEY TODAY THAN 24
HOURS AGO. THERE IS SUFFICIENT COLD POOL ALOFT FOR THIS TIME OF
YEAR AND COMBINED WITH THE SURFACE HEATING SHOULD BE ABLE TO
PRODUCE SOME THUNDERSTORMS. THERE ALSO LOOKS TO BE ENOUGH COLD AIR
TO LOWER SNOW LEVELS ENOUGH TO POSSIBLY PRODUCE AN INCH OR TWO OF
SNOW FOR THE HIGHER ELEVATIONS. SOME SNOW MAY BE OBSERVED BELOW
PASS LEVELS ON I-80 AND US 50 DOWN TO AROUND 5000 FEET BUT I DONT
EXPECT ANY THING WOULD STICK TO THE ROAD AT THOSE LEVELS AT THIS
TIME BUT A COUPLE OF THOSE HIGH MOUNTAIN PASSES ON HIGHWAYS 88
AND 4 COULD GET AN INCH OF TWO OF ACCUMULATION.

.EXTENDED DISCUSSION (SATURDAY THROUGH TUESDAY)

BROAD UPPER LOW DRAPED ACROSS THE WESTERN STATES ON SATURDAY...
WITH A DEEPENING TROUGH DIGGING INTO CALIFORNIA. ENERGY EMBEDDED
WITHIN THIS LOW WILL SHIFT THROUGH THE TROUGH AXIS AND OUT OF THE
REGION EARLY IN THE EXTENDED PERIOD. COULD STILL SEE A FEW
LINGERING SHOWERS OVER THE NORTHERN AND CENTRAL SIERRA NEVADA
EARLY SAT... BUT THREAT DIMINISHED LATER SAT. NORTHERLY PRESSURE
GRADIENT STRENGTHENS ACROSS NORCAL IN THE WAKE OF THIS SYSTEM AND
MAY LEAD TO DRY BREEZY WINDS SATURDAY. THE UPPER LEVEL PATTERN
REMAINS BENIGN BUT UNSETTLED SUN INTO MONDAY... BUT HIGH LEVEL
PRESSURE BUILDS THROUGH MID WEEK... LEADING TO MODERATE SUBSIDENCE
WARMING AND SLIGHTLY WARMER THAN AVERAGE TEMPERATURES. DRP

.AVIATION...

PREDOMINATELY VFR SKC CONDS WITH NORTHWESTERLY FLOW ALOFT THROUGH
THE NEXT 24 HOURS.
