..COOLER WITH SCATTERED PRECIP THE NEXT SEVERAL DAYS
..DRYING THIS WEEKEND WITH WARMING INTO NEXT WEEK
METEOROLOGICAL CONDITIONS (WED AM - TUE AM)
THE COOL UPR LOW THAT DRIFTED SOUTH-SOUTHEAST FROM THE CENTRAL OR
COAST YESTERDAY HAS SETTLED OVER THE VICINITY OF BISHOP CA THIS
MORNING...BRINGING BELOW NORMAL TEMPERATURES ON THE ORDER OF MINUS
10- TO MINUS 25-DEGF UNDER SEASONAL NORMALS AND AREAS OF SCATTERED
SHOWERS AND THUNDERSTORMS THAT PRIMARILY IMPACTED PORTIONS OF
NORTHERN CA OVER INTO NORTHWEST NV. GIVEN THE CONVECTIVE NATURE OF
THE PRECIP...SOME AREAS SAW A FEW HUNDREDTHS OF AN INCH WHILE THOSE
LOCATIONS UNDER STRONGER CELLS SURPASSED THE 1.00-INCH MARK.
TODAY WILL SEE THE UPR LOW WOBBLE AROUND A SIMILAR LOCATION TO
ITS PRESENT SPOT WITH SCATTERED PRECIP IMPACTING THE REGION WITH THE
BEST TOTALS FROM THE TRINITY ALPS...THE SOUTHERN CASCADES...AND MUCH
OF THE SIERRA SPREADING INTO PORTIONS OF WESTERN NV. SPC DOES
HIGHLIGHT THIS AREA FOR GENERAL THUNDERSTORMS OVER THE NEXT 24
HOURS. THIS CONVECTIVE NATURE TO THE PRECIP WILL MAKE SPECIFIC
AMOUNTS TOUGH TO PREDICT...BUT AVERAGED AMOUNTS ANYWHERE FROM 0.25-
TO 0.75-INCH ARE ANTICIPATED.
INTO THURSDAY...THE UPR LOW WILL INITIALLY REMAIN RELATIVELY
STATIONARY BEFORE FINALLY STARTING TO DRIFT OFF TOWARD THE EAST AS A
KICKER SYSTEM MOVES TOWARD THE GULF OF ALASKA AND NORTHEAST PACIFIC.
INDIVIDUAL DISTURBANCES ROTATING AROUND THE UPR LOW WILL BRING THE
BEST OPPORTUNITY FOR PRECIP ACROSS A COUPLE AREAS...INCLUDING THE
SOUTHERN CASCADES AND LENGTH OF THE SIERRA...AS WELL AS AN AREA
ALONG THE CENTRAL CA COAST FROM THE SANTA CRUZ TO THE SANTA LUCIA
MOUNTAINS. AGAIN...AREAL AVERAGED AMOUNTS WILL GENERALLY RANGE FROM
0.25- TO 0.75-INCH.
THE UPR LOW WILL MOVE OVER THE GREAT BASIN ON ITS WAY TOWARD THE
WASATCH ON FRIDAY WITH PRECIP SHIFTING EASTWARD AND PRIMARILY
FOCUSED OVER NORTHEAST CA AND THE NORTHERN PORTIONS OF NV WITH THE
BEST AMOUNTS DURING THE FIRST HALF OF THE DAY. FINALLY INTO THE
WEEKEND AND EARLY NEXT WEEK...THE SYSTEM WILL LIFT NORTHWARD TO THE
NORTHERN ROCKIES...WHILE HEIGHTS START TO INCREASE OVER CA AND NV.
THIS WILL BRING DRIER CONDITIONS TO THE REGION AND WARMING
TEMPERATURES.
FREEZING LEVELS THIS MORNING ARE LOWEST ACROSS NORTHERN/CENTRAL CA
INTO WESTERN NV...GENERALLY RANGING FROM 6500- TO 7500-FEET AND
INCREASING AS DISTANCE FROM THE UPR LOW BECOMES GREATER. THESE
OVERALL NUMBERS WILL CONTINUE THROUGH TODAY BEFORE STARTING TO
INCREASE TOMORROW AS THE SYSTEM WEAKENS A BIT AND STARTS TO MOVE OFF
TOWARD THE EAST. BY LATE THURSDAY INTO FRIDAY...LOOK FOR FREEZING
LEVELS TO RANGE FROM 8000- TO 9000-FEET NEAR THE CORE OF THE SYSTEM
OVER DEATH VALLEY NP...INCREASING AT GREATER DISTANCES FROM THE
PRIMARY CIRCULATION. THEN THROUGH THE WEEKEND AS HEIGHTS BUILD...THE
FREEZING LEVELS WILL JUMP AND RANGE FROM 10000-FEET NORTH TO ABOUT
14500-FEET SOUTH. INTO NEXT WEEK...BY TUESDAY MORNING...LOOK FOR
A RANGE OF ABOUT 13000- TO 15000-FEET.
