DISCUSSION
PRELIMINARY LIQUID PRECIPITATION REPORTS RANGE FROM AROUND AN INCH
IN THE UPPER TERRAIN TO NEAR 0.25 INCHES IN FAR WESTERN NV VALLEYS
ALONG THE SIERRA FRONT. RAIN TOTALS DROP OFF CONSIDERABLY EAST OF
HIGHWAY 395 WITH LESS THAN 0.05 INCHES REPORTED IN THE BASIN AND
RANGE SO FAR. A COUPLE STRONGER BANDS ASSOCIATED WITH THE COLD FRONT
PASSAGE ALLOWED PRECIPITATION TO OUTMANEUVER THE DEFENSE OF THE
SIERRA AND BRING A DECENT BOUT OF WETTING RAINS. SNOW LEVELS (AS OF
1AM) HAVE BEEN HOVERING ABOVE 8000 FEET AND SEVERAL REGIONAL WEBCAMS
ARE SHOWING SNOW AT HIGHER ELEVATION SIERRA SITES IN THE TAHOE
BASIN.
RAIN AND HIGH ELEVATION SNOW WILL PERSIST THROUGH MIDDAY TODAY
BEFORE DISSIPATING LATER THIS AFTERNOON. SNOW LEVELS WILL STAY ABOVE
8000 FEET WITH MOST ACCUMULATING SNOWFALL AT THE HIGHEST SIERRA
PEAKS/ELEVATIONS. BE AWARE OF TRAVEL IMPACTS THROUGH THE HIGHER
MOUNTAIN PASSES IN MONO AND ALPINE COUNTIES (I.E. EBBETTS, SONORA,
TIOGA). FOR THE TAHOE PASSES (I.E., DONNER, CARSON, ECHO) THERE
SHOULD BE MAINLY RAIN/WET ROADS THROUGH TODAY. WET ROADS ARE STILL
INCREDIBLY SLICK SO BE SURE TO SLOW DOWN AND ALLOW INCREASED
BRAKING DISTANCE DURING THIS INCLEMENT CONDITIONS.
PLAN ON DECREASING SHOWER COVERAGE FROM NORTH TO SOUTH BY MIDDAY
TODAY, ALTHOUGH SHOWERS MAY PERSIST IN THE EASTERN SIERRA AS THE
UPPER LOW WOBBLES EASTWARD AND WRAPS NORTHWARD AGAIN BY SATURDAY.
THIS WILL RESULT IN A RENEWED PRECIPITATION EFFORT SATURDAY WITH
ADDITIONAL RAIN AND SNOW CHANCES. WE WILL SEE A TRANSITION IN THE
SNOW LEVELS FROM AROUND 9000 FEET DOWN TO NEAR 6500-7000 FEET BY
SUNDAY NIGHT AS THE COLD CORE OF THE UPPER LOW FINALLY ADVANCES
ACROSS THE EASTERN SIERRA AND WESTERN NEVADA. IMPACTS SHOULD REMAIN
LARGELY CONFINED TO THE HIGHEST SIERRA PASSES WITH THE REPEAT VISIT
OF THE LOW. MEANWHILE, THE TRAJECTORY OF THE PRECIPITATION WILL
PROMOTE WIDESPREAD WETTING RAIN POTENTIAL FOR AREAS ALONG AND SOUTH
OF INTERSTATE 80 ON SATURDAY WITH A NORTHWARD PROGRESSION FOR MOST
AREAS IN NE CA AND NW NV ON SUNDAY.
THE STORMY, ACTIVE WEATHER PATTERN STICKS AROUND FOR EARLY NEXT WEEK
AS WE'RE DIALING IN ON ANOTHER STORM FOR MONDAY. THIS COLDER STORM
HAS THE POTENTIAL TO ADVANCE INTO THE REGION WITH LOWER SNOW LEVELS,
BUT IT WILL BE TBD FOR NOW AS THE STORM TRACKS HAVE BEEN FINICKY.
PLAN ON NOTICEABLY COLDER CONDITIONS (HIGHS CLOSER TO JANUARY
NORMALS) AND LOW TEMPERATURES DIPPING INTO THE SUB-FREEZING CATEGORY
FOR MONDAY AND TUESDAY NIGHTS.

WINDS: SURFACE WIND GUSTS HAVE ALSO DISSIPATED RAPIDLY WITH THE
ONSET OF RAIN AT MOST TERMINALS. FL100 WINDS WILL CONTINUE TO TAPER
THROUGH 12Z FRIDAY, BUT REMAIN SOUTHERLY. WITH THE STRONGER WINDS
ALOFT THROUGH EARLY FRIDAY THERE MAY STILL BE REMNANT LLWS IMPACTS.
OTHERWISE, SURFACE WINDS WILL REMAIN LIGHT.
PRECIPITATION: PERIODS OF MVFR TO OCCASIONAL IFR CONDITIONS AND
MOUNTAIN OBSCURATION WILL PERSIST AT KTRK-KTVL-KMMH THROUGH 18Z
FRIDAY. RESIDUAL LIGHT SHOWERS MAY REDUCE CIGS/VIS TO MVFR
CONDITIONS AT KRNO-KCXP-KMEV. PRECIPITATION WILL BACK OFF AFTER 18Z
FRIDAY WITH IMPROVED FLIGHT CONDITIONS INTO SATURDAY MORNING BEFORE
ANOTHER ROUND OF SHOWERS ARRIVES.
