TO PEAK TODAY. CONDITIONS WILL SLOWLY EASE EARLY NEXT WEEK WITH RAIN
POTENTIAL MID WEEK.
KEY MESSAGES
-INTERIOR HIGHS IN THE LOW 80S THIS WEEKEND.

DISCUSSION
A RIDGE OF HIGH PRESSURE WILL PEAK TODAY. MUCH WARMER
HIGHS FRIDAY HAVE MADE CONDITIONS MUCH COOLER OVERNIGHT, THOUGH SOME
VERY LIMITED FROST AT HIGHER ELEVATIONS IS STILL POSSIBLE BY
SUNRISE. HIGH TEMPERATURES WILL APPROACH THE MID 80S WITH A 20%
CHANCE OF SOME HIGHS OVER 85 AROUND UKIAH. EVEN NEAR SHORE, MARINE
INFLUENCE AND WINDS WILL BE SUFFICIENTLY WEAK TO ALLOW HIGH
TEMPERATURES IN THE MID 60S. CONDITIONS SUNDAY WILL BE VERY SIMILAR
THERE IS HIGH CONFIDENCE THAT HIGH PRESSURE WILL GRADUALLY WEAKEN BY
EARLY NEXT WEEK WITH A LOW PRESSURE SYSTEM MOVING IN ALONG SHORE.
THE PATH, STRENGTH, AND MOISTURE ASSOCIATED WITH THIS LOW REMAINS
HIGHLY VARIABLE. OVERALL CHANCES HAVE CONTINUED TO SLIGHTLY
INCREASE, WITH GENERALLY TIMING NOW PUSHING A LITTLE LATER, MORE INTO
WEDNESDAY. ABOUT 55% OF MODEL ENSEMBLE MEMBERS NOW SUGGEST WETTING
RAIN ACROSS THE NORTHERN HALF OF THE AREA, WITH A 20% CHANCE OF LOW
ELEVATION AMOUNTS OVER 0.5 INCHES THOUGH STILL LESS THAN 10% SHOW
POTENTIAL FOR ANY AMOUNT OVER 1.0 INCH. REGARDLESS OF THE ACTUAL
AMOUNT OF RAIN THAT FALLS, LOW PRESSURE PUSH EAST OF THE AREA WILL
ENCOURAGE STRONG NORTH WINDS TO PUSH ALONG SHORE AROUND WEDNESDAY
AND THURSDAY, ENHANCING MARINE INFLUENCE. /JHW

COVERAGE. LIGHT AND VARIABLE WINDS, BECOMING W-NW AROUND 5 KTS IN

OF A WEAK COLD FRONT. WINDS ARE EXPECTED TO CONTINUE STRENGTHENING,
