DISCUSSION
PER LATEST WATER VAPOR IMAGERY, A MID-LEVEL TROUGH IS CURRENTLY
LOCATED OVER EAST-CENTRAL CALIFORNIA, AND WILL CONTINUE ITS
EASTWARD TREK THROUGH THIS EVENING, MAINTAINING PRECIPITATION
CHANCES ACROSS PORTIONS OF THE AREA. EARLY THIS MORNING, THE
GREATEST CONCENTRATION OF LIGHT TO MODERATE SHOWERS EXISTS FROM
THE SOUTHERN GREAT BASIN SOUTHEASTWARD ACROSS NORTHWESTERN
ARIZONA, WITH ADDITIONAL ACTIVITY OVER NORTHERN INYO COUNTY.
RAINFALL TOTALS ACROSS THE LOWER ELEVATIONS HAVE THUS FAR REMAINED
UNDER 0.20 INCH, WITH THE EXCEPTION OF BISHOP AND OTHER LOCATIONS
IN THE NORTHERN OWENS VALLEY WHERE AROUND 0.50 INCH OF RAINFALL
HAS BEEN MEASURED. IN THE HIGHER TERRAIN, AMOUNTS GENERALLY RANGE
FROM 0.25 TO 0.50 INCH, WITH THIS ACTIVITY EXPECTED TO CONTINUE TO
SHIFT NORTHWARD THROUGH THE MORNING HOURS. AS THE AFOREMENTIONED
TROUGH TRANSLATES EASTWARD OVER THE REGION TODAY, PRECIPITATION
CHANCES WILL LINGER, FOCUSED MAINLY ACROSS THE SOUTHERN GREAT
BASIN AND MOHAVE COUNTY (60 TO 90 PERCENT CHANCE), THOUGH ISOLATED
TO SCATTERED LIGHT SHOWERS CAN BE EXPECTED ELSEWHERE (10 TO 30
PERCENT CHANCE). A BULK OF THE ACTIVITY WILL CONTINUE TO BE LIGHT
TO MODERATE SHOWERS, THOUGH COOLING TEMPERATURES ALOFT AND
MAINTAINED ASCENT WILL YIELD AROUND A 10 PERCENT CHANCE FOR
EMBEDDED THUNDERSTORMS AND LOCALLY ENHANCED RAINFALL RATES,
PARTICULARLY OVER LINCOLN COUNTY AND THE ARIZONA STRIP.
TEMPERATURES TODAY WILL BE AROUND 10 TO 15 DEGREES BELOW NORMAL,
RANGING FROM THE MID 50S TO MID 70S FOR MOST. THESE COOLER
TEMPERATURES LINGER INTO MONDAY, ALONG WITH SOUTHERN GREAT BASIN
RAIN CHANCES, BEFORE THE SYSTEM FINALLY EXITS THE REGION. IN
ADDITION TO THE PRECIPITATION AND COOLER TEMPERATURES, BREEZY TO
WINDY CONDITIONS PERSIST, ESPECIALLY ACROSS THE WESTERN MOJAVE
DESERT AND MORONGO BASIN, WHERE A WIND ADVISORY REMAINS IN EFFECT
THROUGH THIS AFTERNOON. WHILE THE STRONGEST WINDS WITH GUSTS TO 50
MPH ARE EXPECTED THIS MORNING, WINDS WILL BE SLOW TO DIMINISH,
GRADUALLY WEAKENING THROUGH MID TO LATE AFTERNOON. LIGHTER
SOUTHWESTERLY BREEZES WILL CONTINUE MONDAY.
TUESDAY ONWARD, A QUICK RETURN TO ABOVE NORMAL TEMPERATURES IS
EXPECTED, WITH ENSEMBLES AND CLUSTER ANALYSES IN GOOD AGREEMENT
REGARDING RIDGING BUILDING OVER THE PACIFIC NORTHWEST AND GREAT
BASIN. THE FLY IN THE OINTMENT IS A DISTURBANCE THAT WILL TAKE
SHAPE OFF OF THE SOUTHERN CALIFORNIA COAST MIDWEEK AND EVENTUALLY
TRANSLATE EASTWARD TOWARD THE END OF THE WEEK. THERE IS STILL
UNCERTAINTY REGARDING THE TIMING AND TRAJECTORY OF THIS SYSTEM,
THOUGH CURRENT INDICATIONS ARE THAT IT WILL PASS TO THE SOUTH OF
THE AREA, CLOSER TO THE US-MEXICO BORDER. ITS DEPTH AND PRECISE
LOCATION WILL DICTATE WHAT, IF ANY, LOCAL IMPACTS ARE FELT, THOUGH
INCREASED CLOUD COVER AND A RETURN OF LOW PRECIPITATION CHANCES
CANNOT BE RULED OUT, MAINLY SOUTH OF I-15. STAY TUNED.
