BROAD TROUGHING ORIGINATING FROM A DEEP CLOSED LOW OVER SOUTH-
CENTRAL CANADA WILL DOMINATE THE SYNOPTIC PATTERN OVER THE NEXT
COUPLE OF DAYS. THIS UPPER-LEVEL FLOW WILL USHER A CLOSED LOW INLAND
OFF THE SOUTHERN CALIFORNIA COAST THROUGH THE DAY TODAY. THIS LOW
WILL BRING GUSTY WINDS AND MODEST MOISTURE ALONG WITH IT. PWATS WILL
INCREASE BY 0.20 TO 0.40 INCHES AS THE DAY PROGRESSES, PUTTING THE
REGION AT 150 TO 200 PERCENT OF NORMAL FOR THIS TIME OF YEAR. BEST
CHANCES AND BEST COVERAGE OF SHOWERS AND THUNDERSTORMS WILL EXIST
ACROSS THE SOUTHERN GREAT BASIN - PARTICULARLY NORTHERN INYO,
ESMERALDA, SOUTHERN NYE, AND LINCOLN COUNTIES LATE THIS AFTERNOON
AND THROUGH THE EVENING. GREATEST RAINFALL AMOUNTS EXPECTED IN THE
MOUNTAINS OF ESMERALDA COUNTY, WITH LOW CHANCES OF ISOLATED FLOODING
UNDERNEATH STRONGER STORMS. SNOW LEVELS WILL FALL TO 6000-7000 FEET,
SO LIGHT FALL CANNOT BE RULED OUT ABOVE 7000 FEET. THERE EXISTS A 20
TO 40 PERCENT CHANCE OF ISOLATED SHOWERS AND THUNDERSTORMS ACROSS
THE MOJAVE DESERT, WITH BEST CHANCES IN THE HIGHER TERRAIN SUCH AS
THE SPRING MOUNTAINS AND SHEEP RANGE. THE LOW LEVELS OF THE
ATMOSPHERE ARE VERY DRY, WITH INVERTED V SOUNDINGS SLOWLY ERODING
TONIGHT; DCAPE VALUES ACROSS THE MOJAVE DESERT WILL RANGE FROM 500
TO OVER 600 J/KG THROUGH THE AFTERNOON AND EARLY PART OF THE EVENING
BEFORE GRADUALLY DECREASING. THIS WILL RESULT IN STRONG GUSTY WINDS
FROM THE DIRECTION OF ANY SHOWERS OR THUNDERSTORMS THAT FORM. IN
ADDITION TO PRECIPITATION-DRIVEN WIND, WIDESPREAD SOUTHWESTERLY WIND
GUSTS BETWEEN 25 AND 35 MPH WILL CONTINUE THROUGH THE AFTERNOON AND
EVENING, WITH STRONGEST SPEEDS IN THE WESTERN MOJAVE DESERT (50 TO
55 MPH) WHERE A WIND ADVISORY IS IN EFFECT UNTIL 11 AM SUNDAY. WILL
CONTINUE TO ASSESS WHETHER OR NOT THE WIND ADVISORY NEEDS TO BE
EXTENDED IN TIME.
LIGHT SHOWERS CONTINUE IN THE SOUTHERN GREAT BASIN ON SUNDAY AND
MONDAY AS SKIES GRADUALLY CLEAR SOUTH TO NORTH. RIDGING SETS UP
ACROSS THE DESERT SOUTHWEST MID-TO-LATE WEEK, WHICH WILL ALLOW
TEMPERATURES TO REBOUND BACK TO ABOVE-NORMAL. LATE-WEEK INTO THE
WEEKEND, THERE IS SUBSTANTIAL UNCERTAINTY REGARDING THE APPROACH OF
ANOTHER CLOSED LOW OFF THE SOUTHERN CALIFORNIA COAST. STAY TUNED TO
THE FORECAST FOR DETAILS AS WE GET CLOSER.

COMPONENT WITH 20 TO 30 KNOT SOUTHWESTERLY WIND GUSTS CONTINUING
THROUGH THE OVERNIGHT PERIOD AND INTO THE DAY ON SUNDAY FOR

OVERNIGHT BEFORE PICKING BACK UP AROUND MID-MORNING SUNDAY. LIGHT
