.SYNOPSIS...
SHOWERS AND THUNDERSTORMS OVER THE MOUNTAINS DEVELOPING THIS
AFTERNOON AND INTO ADJACENT PORTIONS OF THE VALLEY. THIS PATTERN
WILL PERSIST INTO NEXT WEEK BRINGING CLOUDS AND MAINLY MOUNTAIN
SHOWERS AND THUNDERSTORMS. WELL ABOVE NORMAL TEMPERATURES ARRIVE
MONDAY AND TUESDAY.

.SHORT TERM DISCUSSION...

THE CENTER OF THE CLOSED UPPER LOW IS CENTERED OVER THE SOCAL
COASTLINE THIS MORNING. THE LOW WILL GRADUALLY MOVE INLAND OVER
SOCAL TODAY BEFORE TRACKING NORTHEASTWARD ON SATURDAY. THIS LOW
WILL MAINTAIN INSTABILITY AND MOISTURE OVER OUR REGION. THUS,
EXPECT THE NEXT SEVERAL DAYS TO BE SIMILAR WITH AFTERNOON/EVENING
SHOWERS AND THUNDERSTORMS PRIMARILY OVER THE MOUNTAINS...WITH
LESSER CHANCES IN THE ADJACENT VALLEY AREAS. RESIDENTS SHOULD BE
PREPARED FOR LIGHTNING, SMALL HAIL, GUSTY WINDS, AND BRIEF
DOWNPOURS IF IN THE VICINITY OF THUNDERSTORMS.

FOR TODAY, THE HRRR INDICATES THAT CONVECTION WILL BEGIN AFTER 10
AM ALONG THE WESTERN SIERRA SLOPES INCLUDING SOME FOOTHILL
LOCATIONS (SUCH AS BUTTE, YUBA & NEVADA COUNTIES). SOME
THUNDERSTORMS MAY WORK THEIR WAY TOWARDS THE EASTERN CENTRAL
VALLEY JUST BELOW THE FOOTHILLS BY EARLY EVENING. THE GREATER
RAIN TOTALS WILL BE TOWARDS THE SIERRA CREST WITH PEAK AMOUNTS
AROUND A HALF INCH. VALLEY HIGHS WILL JUST BE NEAR TO A FEW
DEGREES ABOVE NORMAL. VALLEY MAX TEMPS - UPPER 80S TO LOW 90S,
DELTA - 70S, FOOTHILLS - 70S TO MID 80S, MOUNTAINS - 60S AND 70S.

ON SATURDAY, AS THE LOW MOVES NORTHEASTWARD, THIS WILL BRING A
SLIGHTLY COOLER AIRMASS OVER NORCAL WHICH MEANS DAYTIME HIGHS WILL
NUDGE DOWNWARD A DEGREE OR TWO.

BY SUNDAY AND MONDAY THE LOW WILL BE CENTERED TO OUR EAST OVER
THE GREAT BASIN WHICH MEANS MOST OF THE SHOWER ACTIVITY WILL BE LIMITED
TO THE SIERRA. WITH LESS INFLUENCE FROM THE LOW, TEMPERATURES WILL
WARM AGAIN. SUNDAY HIGHS WILL RANGE A FEW DEGREES UP TO 10 DEGREES
ABOVE NORMAL...WARMEST TEMPS IN THE THE NORTHERN SACRAMENTO VALLEY
WHERE WE MIGHT SEE A FEW TRIPLE DIGIT READINGS. MONDAY IS WHEN THE
HEAT REALLY KICKS IN...MUCH OF THE VALLEY WILL BE IN THE MID 90S

.EXTENDED DISCUSSION (TUESDAY THROUGH FRIDAY)
UPPER RIDGING BUILD INTO THE REGION TUESDAY FROM THE DESERT SW.
HOWEVER, ANOTHER CUTOFF LOW AS PLACED ITSELF OFF OF THE CENTRAL CA
COAST AND SLOWLY KICKS ACROSS THE AREA THROUGH THURSDAY AS A
TRANSITORY TROUGH MOVES THROUGH THE PAC NW. MOISTURE REMNANTS FROM
BLANCA MAY BE ENTRAINED IN WITH THE PASSAGE OF THIS CUTOFF LOW.
THEREFORE MOISTURE, INSTABILITY AND A TRIGGER SHOULD BE IN PLACE
FOR SHOWER AND THUNDERSTORM ACTIVITY. TEMPERATURES DECREASE A FEW
DEGREES WEDNESDAY(STILL IN THE 90S ACROSS THE VALLEY) DUE TO THE
LOWER HEIGHTS FROM THE LOW, AND STABILIZE THROUGH FRIDAY.
