AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
442 AM PDT SUN SEP 29 2013

.SYNOPSIS...
MOIST PACIFIC STORM WILL BRING RAIN AND BREEZY TO WINDY
CONDITIONS TODAY INTO MONDAY WITH POTENTIAL SNOWFALL WELL ABOVE
PASS LEVELS. DRY WITH CONTINUED BELOW NORMAL TEMPERATURES TUESDAY
THROUGH MIDWEEK WITH NORTHERLY WINDS RETURNING WEDNESDAY INTO
FRIDAY.

DISCUSSION...
BROAD UPPER LEVEL TROUGH OVER EASTERN PACIFIC WITH SEVERAL
VORTICITY WAVES IN THE PATTERN. THE FIRST WAVE MOVED INTO
WASHINGTON/OREGON EARLIER THIS MORNING. THE SOUTH END OF THIS
FEATURE IS BRINGING SOME RAIN TO NORTHWEST CALIFORNIA. THE PATTERN
IS PRETTY ZONAL (WEST TO EAST ORIENTATION) WITH DECENT OROGRAPHIC
OVER THE COASTAL RANGE AND SIERRA. THE SYSTEM WILL SPREAD
PRECIPITATION EAST AND SOUTHWARD DURING THE DAY AS THE NEXT WAVE
INFLUENCES THE AREA. THE GREATEST PRECIPITATION CHANCES THROUGH
TONIGHT LOOK TO BE PRIMARILY NORTHWARD OF I-80 IN THE VALLEY TO
JUST SOUTH OF HWY 50 IN THE MOUNTAINS. SHOWER CHANCES WILL REMAIN
ON MONDAY BEHIND THE FRONT BEFORE ENDING EARLY MONDAY EVENING FOR
MOST LOCATIONS. SOME ISOLATED SHOWERS MAY LINGER OVER THE WEST
SLOPES NORTH OF I-80 UNTIL AROUND MIDNIGHT TUESDAY.

WINDY CONDITIONS WILL INCREASE OVER THE CREST THIS MORNING WITH
THE STRONGEST WINDS LIKELY TO OCCUR FROM AROUND US-50 NORTHWARD.
WINDS WITHIN THE VALLEY WILL ALSO INCREASE LATER TODAY AS THE FRONT
APPROACHES WITH THE WINDS BECOMING BREEZY. SNOW LEVELS WILL BE
VERY HIGH WITH THIS SYSTEM, SO ONLY THE HIGHER PEAKS MAY BE ABLE TO
SEE SOME SNOWFALL FROM THIS SYSTEM. THIS SYSTEM DOES NOT LOOK
UNSTABLE ENOUGH TO PRODUCE ANY SIGNIFICANT THUNDERSTORM COVERAGE.
PRECIPITATION AMOUNTS WILL BE GREATEST OVER SHASTA COUNTY WHERE A
COUPLE OF INCHES OF PRECIPITATION COULD FALL OVER THE WESTERN
MOUNTAINS AND FOOTHILLS. AMOUNTS WILL TAPER TO AROUND AN INCH OVER
THE FEATHER RIVER BASIN TO AROUND A QUARTER INCH OVER NEVADA
COUNTY. RAIN WITHIN THE VALLEY WILL RANGE FROM NEAR AN INCH
SURROUNDING REDDING TO A FEW HUNDREDTHS AROUND THE SACRAMENTO
AREA. THE LOCALIZED CONVERGENCE THAT CAUSES BANDS OF SHOWERS TO
TRAIN OVER NORTHWEST TO NORTH REDDING HAS A POTENTIAL TO FORM
TODAY AND MONDAY AS THE SOUTHERLY LOW LEVEL WINDS INTERACT WITH
THE WESTERLY MID LEVEL WINDS.

DRY CYCLONIC FLOW WILL CONTINUE OVER THE REGION FOR TUESDAY AS THE
TROUGH AXIS MOVES THROUGH CALIFORNIA. AS THE TROUGH MOVES INTO
NEVADA, THE UPSTREAM PATTERN AMPLIFIES WITH A NORTHWEST JET OVER
NORCAL. THIS PATTERN WILL GENERATE A DRYING, OFFSHORE WIND EVENT
WEDNESDAY INTO FRIDAY. AFTER THE TROUGH PASSAGE, FREEZING
OVERNIGHT TEMPS ARE A CONCERN TUESDAY AND WEDNESDAY MORNINGS OVER
HIGHER MOUNTAIN REGIONS, ESPECIALLY NORTHEAST SHASTA COUNTY/BURNEY
BASIN AND WESTERN PLUMAS COUNTY/LAKE ALMANOR AND QUINCY BASINS.
