KEY MESSAGES

AND EASTERN KERN COUNTY THURSDAY INTO THE WEEKEND. MINIMUM RHS

DISCUSSION
LATEST SATELLITE IMAGERY SHOWS SOME CLOUDS STILL LINGERING OVER
THE SIERRA NEVADA AS THE TROUGH MOVES INLAND ALONG WITH WHATEVER
IS LEFT OF RACHEL. LUCKILY FOR US TONIGHT, THE CLEARING SKIES
ALLOWS FOR TEMPERATURES TO DROP WITH THE VALLEY TO HAVE A 70 TO
100 PERCENT CHANCE OF LOWS OF 50 DEGREES AND BELOW. THE COOLER
OVERNIGHT TEMPERATURES CONTINUE AS THE VALLEY HAS A GREATER THAN
50 PERCENT CHANCE OF LOWS AT OR BELOW 60 DEGREES.
DESPITE THE FALL-LIKE NIGHT TEMPERATURES, WE WILL WARM UP AGAIN
THANKS TO A RIDGE OF HIGH PRESSURE WHICH SLIDES IN TOMORROW AND
WILL STRENGTHEN THROUGH THE WEEK THAT IT COVERS MOST OF THE U.S.
BY THIS WEEKEND. LATEST PROBABILITIES SHOWS A 30 TO 55 PERCENT
CHANCE OF HIGHS GETTING UP TO 90 FRIDAY THROUGH SUNDAY. HOWEVER,
THE BIG STORY WITH THIS ALSO IS THE POSSIBILITY OF THE
DEVELOPMENT OF MONO WINDS. THIS IS LARGELY DUE TO PART OF THE
TROUGH GETTING CUTOFF AND RETROGRADING WEST THAT THE RIDGE OF
HIGH PRESSURE BECOMES A REX BLOCK BY THURSDAY. LATEST MODELS
SHOW MINIMUM RH VALUES OVER THE SIERRA NEVADA AND MOJAVE DESERT
IN THE TEENS WITH STRONGER EASTERLY FLOWS. AS A RESULT, NO
PRECIPITATION IS EXPECTED THROUGH SUNDAY. HOWEVER, THE CPC SHOWS
EQUAL CHANCES TO A 33 TO 40 PERCENT CHANCE OF ABOVE AVERAGE
PRECIPITATION IN THE 6-10 AND 8-14 DAY OUTLOOKS AS ENSEMBLES ARE
PICKING UP ON A TROUGH SLIDING IN NEXT MONDAY INTO THE WEEK.
