SHORT TERM...
SNOW CONTINUES ACROSS THE REGION THIS MORNING...MAINLY FROM LAKE
TAHOE NORTH. AREA RADARS SHOW PRECIP ACROSS CALIFORNIA MAINLY FROM
I-80 NORTH. SATELLITE IMAGERY SHOWS THE DEEP UPPER LOW JUST OFF THE
WASHINGTON COAST. THIS SYSTEM WILL START TO MOVE INLAND TODAY. A
VORT MAX SEEN ON IR SATELLITE SHOULD MOVE INTO NRN CALIFORNIA TODAY
AS A RESULT OF A JET MAX MOVING EAST THROUGH THE BASE OF THE
TROUGH. A SECOND VORT MAX SEEN ON SATELLITE IS PROGGED BY THE GFS
TO DIG THE TROUGH FARTHER SOUTH AND CARRY MOISTURE INTO THE CENTRAL
SIERRA OVERNIGHT. AS THE JET MOVES ACROSS THE REGION ITS DYNAMICS
WILL COMBINE WITH OROGRAPHICS TO PRODUCE HEAVY SNOWFALL FROM APPROX
21Z TODAY THROUGH 06Z TUESDAY. ONE TO 2 FEET OF SNOW IS EXPECTED IN
THE NRN SIERRA WITH 2 TO 3 FEET EXPECTED THIS AFTERNOON AND OVERIGHT
IN THE CENTRAL SIERRA FROM THE TAHOE BASIN SOUTH INTO MONO COUNTY.
STRONG WINDS AHEAD OF THIS SYSTEM WILL CAUSE WHITEOUT CONDITIONS IN
THE HIGHER ELEVATIONS.
THE SNOWFALL WILL START TO TAPER OFF LATE TUESDAY. HOWEVER...WITH
UPPER TROUGH OVER THE REGION...THE CYCLONIC FLOW AND COLD AIR ALOFT
WILL KEEP THE CHANCE OF SNOW IN THE FORECAST THROUGH WEDNESDAY. A
VERY COLD AIR MASS WILL FILTER INTO THE REGION ON WEDNESDAY. AS THE
AFTERNOON DISCUSSION MENTIONED...THIS COLD AIR MASS COMBINED WITH
THE SNOW COVER...WILL BRING VERY COLD TEMPERATURES TO THE REGION
WEDNESDAY AND ESPECIALLY THURSDAY MORNINGS WITH READINGS CLOSE TO 10
DEGREES BELOW NORMAL. OHARA
.LONG TERM...THURSDAY THROUGH SUNDAY...
MODELS IN BETTER AGREEMENT THIS MORNING ON THE PATTERN INTO THE
WEEKEND. DIRTY NORTHWEST FLOW WILL CONTINUE THURSDAY BEFORE A
MODERATE AMPLITUDE RIDGE MOVES INTO THE REGION BY SAT. MODELS
CONTINUE TO SHOW A PROGRESSIVE PATTERN...BUT WITH THE BETTER
AGREEMENT THE ONLY ISSUE IS HOW LONG DOES THE RIDGE REMAIN. FOR
NOW...HAVE DECIDED TO HOLD ONTO THE RIDGE THROUGH SUN PER EURO WITH
MORE SOUTHWEST FLOW. 00Z GFS AGREES...ALTHOUGH SOME ENSEMBLE MEMBERS
ARE A BIT FASTER WITH THE NEXT SYSTEM. WILL KEEP DRY FORECAST INTO
THE WEEKEND WITH NEAR NORMAL TEMPS. AHEAD OF THE NEXT SYSTEM...WOULD
NOT BE SURPRISED TO SEE A DAY OR TWO OF ABOVE NORMAL TEMPS BUT WITH
TIMING ISSUES...WILL PLAY IT CONSERVATIVE. WALLMANN
