NATIONAL WEATHER SERVICE LAS VEGAS NV

.SYNOPSIS...A LOW PRESSURE SYSTEM IS APPROACHING THE CENTRAL
CALIFORNIA COAST AND IS BRINGING SNOW TO THE HIGHER ELEVATIONS OF
THE SIERRA AND SOME BREEZY WINDS THERE. CLOUDS WILL OVER SPREAD THE
ENTIRE AREA BY THIS AFTERNOON WITH SNOW SHOWERS OVER THE HIGHER
ELEVATIONS OF ESMERALDA...INYO AND NORTHERN LINCOLN COUNTIES. GUSTY
SOUTHWEST WINDS WILL OCCUR OVER MOST LOCATIONS AS WELL. THE

&&

.UPDATE...SNOW STILL COMING DOWN IN THE SIERRA WITH 9 TO 12 INCHES

GUIDANCE POINT TO AT LEAST ANOTHER 3 OR 4 HOURS OF SNOW UP
THERE...SO ISSUED A WINTER STORM WARNING FOR 12-15 INCHES OF SNOW.
FURTHER EAST...CLOUDS ON THE MARCH AND EXPECT THE EASTERN HALF OF
THE CWA TO SEE A FEW CLOUDS THIS AFTERNOON WITH THE BEST CHANCE FOR
PRECIP THERE IN THE NORTHEAST PORTION OF THE CWA...BUT POPS
JUSTIFIABLY LOW GIVEN ONLY MARGINAL MOISTURE. EXPECT ALL PRECIP TO
WIND DOWN QUICKLY THIS EVENING LEAVING CLEARING SKIES FOR SATURDAY.
&&

.PREV DISCUSSION...330 AM PST FRI MAR 3 2006...SHORT TERM...FETCH OF
LOW LEVEL MOISTURE FROM A SHORTWAVE THAT MOVED INTO NORTHERN
CALIFORNIA YESTERDAY WILL CONTINUE TO WORK SOUTHEAST TODAY. RADAR
AND SURFACE OBSERVATIONS INDICATING LIGHT RAIN ACROSS THE SOUTHERN
SAN JOAQUIN VALLEY WITH MOISTURE BUILDING UP ON THE WESTERN SLOPES
OF THE SOUTHERN SIERRA. SO FAR NO MOISTURE HAS MADE IT OVER THE
CREST...BUT THAT SHOULD CHANGE WITHIN THE NEXT FEW HOURS. STILL
LACKING ANY DEEP MOISTURE AND THIS SHOULD MAINLY BE A WESTERN SLOPES
EVENT...BUT WILL STILL CALL FOR A FEW INCHES OF SNOW ON OUR SIDE.
WILL KEEP SNOW TOTALS BELOW ADVISORY CRITERIA. SOME PRECIPITATION
STARTING TO WORK THROUGH KERN COUNTY AND MAY BRUSH NORTHERN SAN
BERNARDINO COUNTY...HAVE GONE AHEAD AND INCREASED POPS INTO THE
SLIGHT CHANCE CATEGORY THERE. HAVE ALSO ADDED POPS BACK INTO THE
FORECAST FOR THE SOUTHERN NEVADA MOUNTAINS AS IT LOOKS LIKE ENOUGH
ENERGY AND MOISTURE WILL MAKE FOR GOOD OROGRAPHIC CONDITIONS. ONLY
LOOKING FOR A COUPLE OF INCHES OF SNOW THOUGH. WINDS WILL BE THE BIG
STORY OVER SOUTHERN NEVADA WHERE WINDY CONDITIONS SHOULD BE SEEN
OVER MOST AREAS BY THIS AFTERNOON. BOTH THE GFS/NAM SHOWING AN
INCREASE IN SURFACE AND THERMAL GRADIENTS THIS AFTERNOON AND EXPECT
THE STRONGEST WINDS TO OCCUR AFTER NOON AND DROP OFF FAIRLY QUICKLY
AFTER SUNSET THIS EVENING. NEXT IN A SERIES OF PACIFIC STORM SYSTEMS
APPROACHES THE COAST LATE SATURDAY WITH CLOUDS SPREADING OVER MUCH
OF THE CWA BY SUNDAY. NOT LOOKING FOR A LOT OF MOISTURE INITIALLY
WITH ONLY THE EASTERN SIERRA SLOPES SEEING A CHANCE SUNDAY NIGHT.

SHIFTING INTO THE GREAT BASIN IN SOME FORM THE LATER PART OF NEXT
WEEK. PER CURRENT GFS...CLOSED 523 LOW TO BE OVER NORTHEAST NEVADA
BY 00Z FRIDAY WHILE EURO AS A 530 LOW SOUTH OF KLAS. ORIENTATION OF
