DRY WEATHER WILL CONTINUE THROUGH THIS AFTERNOON FOR MOST
LOCATIONS WITH A WEAKENING LOW PRESSURE SYSTEM TRANSITIONING
MOVING OVERHEAD, WHICH WILL PROVIDE ONLY A SLIGHT CHANCE OF
SHOWERS THROUGH THIS AFTERNOON. RAINFALL ESTIMATES FROM THE COAST
TO THE MOUNTAINS ARE EXPECTED TO BE MOSTLY LESS THAN ONE-TENTH
INCH WEST OF THE MOUNTAINS TO LOCALLY ONE-QUARTER INCH IN THE
MOUNTAINS BEING POSSIBLE IF A HEAVIER SHOWER DEVELOPS. THE SNOW
LEVEL WILL FALL TO AROUND 6500 FEET THIS MORNING.
FOR LATE TONIGHT THROUGH SUNDAY, A SECOND LOW PRESSURE SYSTEM
FROM THE NORTHWEST WILL BRING ADDITIONAL RAINFALL RANGING FROM
AROUND ONE-THIRD INCH NEAR THE COAST TO ONE-HALF TO ONE INCH IN
THE MOUNTAINS WITH LESS THAN ONE-QUARTER INCH IN THE HIGH DESERT,
AND LESS THAN ONE-TENTH INCH IN THE LOWER DESERTS, WITH THE
HIGHEST AMOUNTS EXPECTED WITHIN THE SAN BERNARDINO MOUNTAINS OF UP
TO ONE AND A HALF INCHES ACROSS THE COASTAL-FACING SLOPES. A SNOW
LEVEL AROUND 6500 FEET LATE SATURDAY NIGHT WILL RISE TO 6500 TO
7000 FEET LATE ON SUNDAY.
SOME ADDITIONAL SHOWERS COULD LINGER SUNDAY NIGHT INTO MONDAY
MORNING, WITH THE SNOW LEVEL LOWERING TO 5000 TO 5500 FEET LATE
SUNDAY NIGHT INTO MONDAY MORNING.
THERE IS ONLY A SLIGHT CHANCE OF SHOWERS AGAIN TOWARDS THE LATER
HALF OF THE UPCOMING WORK WEEK.
