200 AM PST TUE NOV 4 2008

.SYNOPSIS...A LOW PRESSURE SYSTEM WILL GRADUALLY MOVE THROUGH THE
GREAT BASIN DURING THE FIRST HALF OF THIS WEEK. SHOWERS WILL
TRANSITION FROM RAIN TO SNOW EARLY THIS MORNING AS COLD AIR MOVES
INTO THE REGION. THE THREAT OF SHOWERS WILL CONTINUE THROUGH
WEDNESDAY...WITH A DRYING TREND THURSDAY AND FRIDAY. &&

.SHORT TERM...COLD UNSTABLE AIR MOVING INTO NORTHERN AND CENTRAL
NEVADA THIS MORNING WILL BRING THE THREAT OF ISOLATED
THUNDERSTORMS ALONG WITH THE TRANSITION OF RAIN SHOWERS TO SNOW.
SNOW ACCUMULATIONS ON VALLEY FLOORS TODAY WILL BE LIGHT
HOWEVER...AS MOST OF THE MOISTURE ASSOCIATED WITH THIS SYSTEM IS
PRE-FRONTAL.

COLD AND SLIGHTLY UNSTABLE AIR BEHIND THE INITIAL FRONT WILL KEEP
THE THREAT OF SNOW SHOWERS ACROSS MOST OF NORTHERN NEVADA THROUGH
WEDNESDAY. THE COLD NORTHWESTERLY FLOW WILL KEEP HIGH TEMPERATURES
NEAR OR SLIGHTLY BELOW NORMAL THROUGH THE MIDDLE OF THE WEEK.
BREEZY TO LOCALLY WINDS CONDITIONS ARE POSSIBLE AT TIMES OVER THE

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY. MODELS START OUT IN
GOOD AGREEMENT WITH UPPER RIDGE OVER AREA WITH WARM AND DRY
CONDITIONS IN PLACE. MODELS SHOWING SOME FAIRLY LARGE
DISCREPANCIES WITH SYSTEM MOVING IN DURING THE WEEKEND. GFS IS
MUCH QUICKER JUST BRINGING THROUGH A FAST MOVING OPEN WAVE WHILE
THE ECMWF IS SLOWER AS IT DIGS A CUTOFF LOW INTO SOUTHERN NV BY
LATE SUNDAY. GIVEN RECENT TRACK RECORD OF MODELS...WILL GO CLOSER
TO THE ECMWF FOR THIS FORECAST. USING THE ECMWF SOLUTION...EXPECT
A SLOWER ONSET OF PRECIPITATION WITH POSSIBLY JUST NWRN CWA SEEING
PRECIP LATE SAT AND SPREADING ACROSS AREA FOR SUNDAY. RAISED
TEMPERATURES A FEW DEGREES FOR SAT WITH THE SLOWER TIMING OF THE
SYSTEM AND THE GOOD MIXING THAT USUALLY OCCURS AHEAD OF THESE
STRONG STORM SYSTEMS. AS PRECIP SPREADS ACROSS AREA SUNDAY SNOW
LEVELS WILL BE FALLING TO AROUND 5000-6000 FEET. GIVEN
DISAGREEMENT WITH MODELS WILL NOT HIT THIS SYSTEM REAL HARD IN THE
HWO BUT HAVE MENTION OF ANOTHER COLD FRONT MOVING THROUGH WITH A
CHANCE FOR A LITTLE MORE SNOW. LOOKS LIKE SOME DRIER AIR WILL MOVE
IN FOR EARLY NEXT WEEK AS STORM SYSTEM MOVES ONTO THE PLAINS. JMG
