Weather radar at 4 PM is showing a lot of precip coming in.
By the way, for anyone that doesn't know how to interpret the dBZ scale, here is a nice link:

EXPECTED EARLY INTO MID NEXT WEEK.

INDICATING THE SNOW LEVEL IS RUNNING ABOVE 9000 FEET...BUT SNOW
LEVELS WILL LOWER AS COLDER AIR FILTERS INTO OUR AREA THIS
EVENING. VISIBLE SAT PICS SHOWING INCREASED CLOUDS FROM FRESNO
COUNTY NORTHWARD...BUT SOUTH OF FRESNO COUNTY SKIES ARE MOSTLY
SUNNY AT THIS TIME. WV INDICATING THE LARGE UPPER LOW OFF THE PAC

WRF/GFS INDICATING SHORTWAVE ENERGY ROTATING AROUND THIS UPPER LOW
WILL MOVE INTO OUR AREA TONIGHT SPREADING INCREASED CLOUDS AND

WILL BE MOST NOTICEABLE FROM FRESNO COUNTY NORTHWARD WHERE
PRECIPITATION WILL BECOME LIKELY BY THURSDAY AFTERNOON AS THE
UPPER LOW BEGINS TO PUSH EASTWARD ACROSS NORCAL. TEMPERATURES ON
THURSDAY WILL CONTINUE THEIR DOWNWARD TREND AS THE LOW TO OUR
NORTH PROVIDES OUR AREA WITH UNSEASONABLY COOL AIR FOR LATE MAY.
HOWEVER...THE MAIN UPPER COLD POOL WITH THIS SYSTEM WILL REMAIN
NORTH OF OUR AREA...AND THE 12Z MODELS KEEP THE CAPE AND INSTABILITY
THAT WOULD BE SUFFICIENT FOR THUNDERSTORM DEVELOPMENT WELL TO THE
NORTH OF OUR CWFA. HAVE THEREFORE REMOVED MENTION OF THUNDERSTORMS
FOR THE NORTHERN HALF OF OUR AREA FOR THURSDAY. SNOW ACCUMULATIONS
WITH THIS SYSTEM WILL BE MOST SIGNIFICANT AROUND YOSEMITE PARK
WHERE UP TO 8 INCHES OF NEW SNOW WILL BE POSSIBLE NEAR THE RIDGE
TOPS BY FRIDAY MORNING. ALTHOUGH SNOW LEVELS ARE FAIRLY HIGH AT
THIS TIME...SNOW LEVELS WILL LOWER TO AROUND 5000 FEET BY THURSDAY
NIGHT WITH CAA TAKING PLACE. SINCE THIS STORM IS OUT OF SEASON
WILL LET THE WINTER STORM WARNING RIDE FOR THE SOUTHERN SIERRA
NEVADA FROM KINGS CANYON NORTHWARD THROUGH THURSDAY NIGHT. SOUTH
OF KINGS CANYON ONLY SCATTERED SHOWERS ARE EXPECTED...BUT SOME
RIDGE TOPS MAY PICK UP A FEW INCHES OF FRESH SNOWFALL BY THURSDAY
NIGHT. A SPECIAL WEATHER STATEMENT WAS ISSUED TO HIGHLIGHT THE
SNOWFALL POTENTIAL FOR THE SOUTHERN SIERRAS IN TULARE COUNTY.
MODELS ARE INDICATING THE UPPER TROUGH PUSHING EAST INTO THE GREAT
BASIN ON FRIDAY WITH BACKLASH MOISTURE PROVIDING FOR SOME RESIDUAL
SHOWERS OVER THE SOUTHERN SIERRA NEVADA. MEANWHILE...DRYER AIR
WILL ALLOW FOR SKIES TO CLEAR OUT OVER THE SAN JOAQUIN VALLEY ON
