DISCUSSION
TEMPERATURES ARE ONCE AGAIN REACHING NEAR THE DEWPOINT IN THE
SAN JOAQUIN VALLEY. A FEW SPOTS ARE ALREADY REPORTING MIST WITH
VISIBILITY AT 5 MILES. EXPECT A GRADUAL LOWERING IN VISIBILITY
THROUGH LATER TONIGHT WITH HIGH CONFIDENCE (60-80 PERCENT
PROBABILITY) OF DENSE FOG (VISIBILITY ONE QUARTER MILE OR LOWER)
DEVELOPING BY EARLY FRIDAY MORNING. LOW TEMPERATURES WILL ALSO
REMAIN MILD TONIGHT AND APPROACH THE RECORD HIGH MINIMUM AT
SOME LOCATIONS SUCH AS BAKERSFIELD AND FRESNO. THIS PATTERN WILL
CONTINUE INTO SATURDAY ALONG WITH WARMING DAYTIME HIGHS ACROSS
THE FORECAST AREA.
THE NEXT CHANCE OF RAIN AND HIGH ELEVATION SNOW ARRIVES SUNDAY
OVER THE SIERRA NEVADA AND ADJACENT FOOTHILLS. A SPRINKLE OR A
VERY LIGHT RAIN SHOWER ALSO HAS UP TO A 20 PERCENT CHANCE OF
OCCURRENCE IN NORTHERN PORTIONS OF OUR VALLEY. CHANCES WILL
INCREASE ON SUNDAY NIGHT INTO MONDAY AND SPREAD SOUTHWARD TO
NORTHERN PORTIONS OF KERN COUNTY. DURING SUNDAY EVENING INTO
MONDAY MORNING, THERE IS A SLIGHT CHANCE (UP TO 20 PERCENT) OF A
SPRINKLE OR VERY LIGHT RAIN SHOWER IN NORTHERN PORTIONS OF OUR
