METEOROLOGICAL CONDITIONS (TUE AM - MON AM)
THE PRIMARY WEATHER FEATURE THAT WILL IMPACT THE REGION THROUGH THE
REST OF THIS WEEK IS CURRENTLY MOVING SOUTH-SOUTHEAST FROM THE
CENTRAL OR COAST TO FAR NORTHERN CA THIS MORNING IN THE FORM OF AN
UPR LOW THAT ORIGINATED OVER THE GULF OF ALASKA. THIS SYSTEM IS
ANTICIPATED TO MEANDER ACROSS NORTHERN/CENTRAL CA THE NEXT SEVERAL
DAYS BEFORE BEING KICKED OFF TOWARD THE EAST ACROSS THE GREAT BASIN
BY GENERAL TROFFING EXPECTED TO SET UP OVER THE NORTHEAST PACIFIC.
WHAT THIS MEANS FOR THE REGION THIS WEEK IS WELL BELOW NORMAL
TEMPERATURES RANGING FROM NEGATIVE 10- TO NEGATIVE 25-DEGF BELOW
SEASONAL NORMALS...AND SCATTERED PRECIP PRIMARILY IMPACTING THE
HIGHER TERRAIN OF NORTHERN/CENTRAL CA INTO NORTHWEST NV. BEST TOTALS
LOOK TO BE OVER THE UPPER KLAMATH RIVER BASIN DOWN INTO THE PIT
RIVER BASIN WITH AMOUNTS FROM 0.75- TO 1.50-INCHES. DOWN THE LENGTH
OF THE SIERRA THERE COULD BE ANYWHERE FROM 0.25- TO 0.75-INCH WITH
NORTHWEST NV SEEING SIMILAR AMOUNTS. SOME LOWER ELEVATION STATIONS
COULD SEE SOME LIGHT PRECIP AS WELL. INTO THE WEEKEND...AFTER THE
UPR LOW IS PUSHED DOWNSTREAM...LOOK FOR HEIGHTS TO BEGIN TO RISE
WITH SOUTHWEST FLOW ALOFT. DRIER CONDITIONS WILL BE IN STORE.
FREEZING LEVELS NEAR THE CORE OF THE SYSTEM WILL GENERALLY RANGE
FROM 7500- TO 8500-FEET. AFTER THE AREA OF LOW PRESSURE MOVES EAST
OF THE AREA...LOOK FOR WARMING WITH FREEZING LEVELS FROM 11000- TO
14500-FEET.
