DISCUSSION
FROM CURRENT RADAR IMAGERY WE CAN DETERMINE A HANDFUL OF THINGS:
IT CONTINUES TO SNOW IN THE SIERRA AROUND THE TAHOE BASIN, LIGHT
SHOWERS CONTINUE TO SPREAD ALONG THE SIERRA FRONT INTO THE BASIN
AND RANGE, AND MORE INTENSE BANDS OF SNOW CAN BE SEEN POPULATING
OFF OF LAKE TAHOE. AREAS WITHIN THESE MORE INTENSE SNOW BANDS CAN
EXPECT LOCALLY HIGHER SNOWFALL TOTALS AND SNOWFALL RATES, BUT
WE'LL GET INTO THE DETAILS BELOW.
THE LOW PRESSURE SYSTEM CONTINUING OUR WINTER WEATHER THIS WEEK
CAN BE SEEN SPINNING OFF THE COAST OF THE PACIFIC NORTHWEST. THE
FORECAST CONTINUES TO STAY ON TRACK WITH 1-4" OF SNOW ON VALLEY
FLOORS AND 3-6" FOR FOOTHILLS ABOVE 5000'. SNOWFALL RATES FOR
VALLEYS WILL REMAIN UNDER 1"/HR BUT THOSE MORE INTENSE SNOW BANDS
COULD SEE RATES OVER 1"/HR.
SNOW SHOWERS WILL CONTINUE IN THE SIERRA THROUGH MUCH OF TODAY.
FOR DETAILS ON SNOWFALL TOTALS, RATES, AND SLRS, PLEASE SEE THE
AVALANCHE SECTION BELOW. AREAS OF NE CA ARE STILL ON TRACK TO SEE
2-6" OF SNOW, WITH UP TO 12" ABOVE 7000' AND LOCALLY UP TO 18"
ALONG THE HIGHEST PEAKS THROUGH LATE TONIGHT. OUR FRIENDS OUT IN
THE BASIN AND RANGE ALSO HAVE THE POTENTIAL TO GET IN ON THE SNOW
ACTION TODAY. THAT AFOREMENTIONED LOW? THERE'S TWO TRACKS THAT IT
COULD TAKE TODAY; A HANDFUL OF THE HI-RES MODELS SHOW THE LOW
TRACKING ALONG I-80 OUT PAST WINNEMUCCA. HOWEVER, THE OTHER HALF
WANT TO DRAG THE LOW SOUTH TOWARDS TONOPAH. DEPENDING ON THIS
TRACK, WE COULD SEE ADDITIONAL SNOW IN THE BASIN AND RANGE, BUT
THE QUESTION REMAINS WHERE. IF IT TAKES THE I-80 TRACK, WE COULD
SEE A COUPLE INCHES IN FERNLEY/FALLON, POSSIBLY EVEN DOWN TO
YERINGTON. IF THE LOW DROPS SOUTH, AREAS IN HAWTHORNE AND SMITH
VALLEY COULD SEE A COUPLE OF INCHES, WITH INCREASED SNOWFALL IN
MONO COUNTY AS WELL.
DESPITE THE UNCERTAINTY, WHAT WE ARE CERTAIN ABOUT IS TRAVEL AND
COMMUTE IMPACTS ACROSS MUCH OF THE AREA TODAY. THE AM COMMUTE WILL
BE SLICK ALONG THE SIERRA FRONT, ESPECIALLY OVER BRIDGES, AND NOT
JUST BECAUSE OF LIGHT SNOW SHOWERS OVERNIGHT. ANY REMAINING WATER
WILL HAVE LIKELY REFROZEN, CREATING ICY CONDITIONS. THE PM COMMUTE
MAY ALSO EXPERIENCE IMPACTS AS THE HEAVIEST SNOWFALL IS EXPECTED
BY MIDDAY. WITH TEMPERATURES PLUNGING OVERNIGHT AFTER THE SNOW
TAPERS OFF, BE AWARE OF SLICK AND ICY PATCHES PERSISTING INTO THE
FRIDAY MORNING COMMUTE AS WELL. REMEMBER, TAKE IT SLOW IN SNOW!
ANOTHER PLEASANT WEEKEND IS IN STORE AS DRY CONDITIONS SETTLE BACK
IN, BRINGING LIGHT WINDS AND MILD TEMPERATURES. SAID CONDITIONS
WILL CONTINUE THROUGH AT LEAST SUNDAY. MODEL GUIDANCE HINTS AT
ANOTHER SYSTEM ARRIVING AS EARLY AS MONDAY. WHILE TIMING CONTINUES
TO TREND THIS SYSTEM LATER AND LATER (SEEMS TO BE THE TREND OF
THIS SEASON IN GENERAL), THERE'S HIGHER CONFIDENCE ON THIS BEING A
WARMER SYSTEM. THIS WILL ALLOW FOR HIGHER SNOW LEVELS (CURRENTLY
AROUND OR ABOVE 7000') AND THE RISK FOR RAIN ON SNOW, AND THE
CORRESPONDING FLOODING CONCERNS, FOR VALLEY LOCATIONS. STAY TUNED
FOR MORE CONCRETE DETAILS OVER THE WEEKEND.
