NORTHERN ROCKIES...AFTER HAVING BROUGHT A STRONGER PUSH OF MARINE
AIR THAN ORIGINALLY EXPECTED. CENTRAL AND SOUTHERN SAN JOAQUIN
VALLEY HIGHS SUNDAY WERE ONLY IN THE LOWER TO MID 70S...DOWN SEVERAL
DEGREES FROM SATURDAY.

BASED ON THE LATEST QPF...SNOW AMOUNTS OF AROUND 2 FEET ARE LIKELY
IN THE HIGH COUNTRY OF YOSEMITE NATIONAL PARK...TAPERING OFF TO
AROUND 10 INCHES IN THE HIGH COUNTRY OF SEQUOIA NATIONAL PARK.
WILL UPGRADE THE WINTER STORM WATCH FOR THE SIERRA FROM YOSEMITE
TO KINGS CANYON TO A HEAVY SNOW WARNING...AND ISSUE A SNOW
ADVISORY FOR THE TULARE COUNTY MOUNTAINS. SNOW ACCUMULATIONS ARE
FORECAST TO BE BELOW ADVISORY LEVELS IN THE KERN COUNTY
MOUNTAINS...BUT WILL KEEP THE SPECIAL WEATHER STATEMENT IN PLACE
DUE TO THE POTENTIAL FOR ACCUMULATING SNOW ON THE MAJOR HIGHWAYS

SNOW LEVELS ARE FORECAST TO BE LOW WITH THIS SYSTEM...WITH THE 06Z
GFS AND 12Z NAM FORECASTING 700-MB TEMPERATURES OVER THE AREA TO
FALL TO -12 C BY 12Z TUESDAY. THIS IS IN GOOD AGREEMENT WITH THE
FORECASTED DROP IN 1000-500-MB THICKNESSES TO 5310-5340 METERS...AND
EQUATES TO SNOW LEVELS DOWN TO 3000 FEET. THIS LIKELY WILL LEAD TO
AT LEAST A FEW OF SNOW ON THE HIGHER ELEVATIONS OF THE GRAPEVINE AND
TEHACHAPI PASS...AND SEVERAL INCHES ON THE HIGHER PARTS OF WALKER
PASS.

WINDS IN THE MOUNTAINS AND DESERTS ARE FORECAST TO REACH ADVISORY
LEVELS BY MONDAY AFTERNOON AND CONTINUE THROUGH TUESDAY EVENING.

FORECASTS A 500-MB COLD POOL WITH TEMPERATURES AROUND -32 C OVER THE
REGION AT 12Z TUESDAY...AND TEMPERATURES REMAINING AROUND -30 C
THROUGH 21Z TUESDAY. A 300-MB 120+ KT JET MAX IS FORECAST TO MOVE
OVER THE SOUTHERN HALF OF THE HANFORD WARNING/FORECAST AREA DURING

NEVADA NORTH OF LAKE ISABELLA IN A GENERAL RISK AREA...SO MENTION OF

AIRMASS WILL REMAIN UNSTABLE TUESDAY...WITH ANY HEATING THROUGH
BREAKS IN THE OVERCAST TRIGGERING MORE CONVECTION. WILL KEEP
MENTION OF ISOLATED THUNDERSTORMS FOR ALL PARTS OF THE HANFORD
WARNING/FORECAST AREA FOR TUESDAY.
