* ISOLATED SHOWER AND THUNDERSTORM ACTIVITY POSSIBLE IN THE SIERRA
AND SOUTHWESTERN GREAT BASIN THIS AFTERNOON.

WEATHER RETURNING LATE-WEEKEND.
DISCUSSION
TODAY THROUGH MONDAY.
A SHORTWAVE EMBEDDED IN THE UPPER-LEVEL FLOW WILL MOVE THROUGH THE
MOJAVE DESERT THIS AFTERNOON, ALLOWING FOR A RENEWED CHANCE OF
ISOLATED SHOWERS AND THUNDERSTORMS IN THE SIERRA AND SOUTHWESTERN
GREAT BASIN. RAINFALL AMOUNTS WILL REMAIN LESS THAN A TENTH OF AN
INCH, WITH TOTALS ABOVE 0.05" CONFINED TO THE HIGHER TERRAIN AND
EMBEDDED THUNDERSTORMS. EXPECT WIND GUSTS BETWEEN 20 AND 30 MPH FROM
THE DIRECTION OF THE SHOWER ACTIVITY.
RIDGING BUILDING OVER NORTHERN MEXICO WILL ALLOW TEMPERATURES TO
GRADUALLY WARM UP THROUGH THE WEEK, WITH TEMPERATURES 6 TO 8 DEGREES
ABOVE SEASONAL NORMAL BY FRIDAY. A CLOSED LOW PRESSURE SYSTEM WILL
WEAKEN AS IT PUSHES INTO BAJA CALIFORNIA WEDNESDAY NIGHT INTO
THURSDAY, BRINGING A VERY MODEST SURGE OF MOISTURE INTO THE DESERT
SOUTHWEST. RESULTANT PRECIPITATION CHANCES HAVE FLUCTUATED A BIT,
WITH SLIGHT (10-20 PERCENT) POPS STILL LINGERING IN THE OUTER EDGES
OF THE CWA WEDNESDAY INTO THURSDAY. THAT SAID, ANY PRECIPITATION
THAT FALLS IS EXPECTED TO REMAIN LIGHT. HEADING INTO THE WEEKEND,
TEMPERATURES WILL CONTINUE TO INCREASE UNDER MOSTLY CLEAR SKIES. THE
NEXT WEATHER SYSTEM TO IMPACT OUR FORECAST AREA WILL DROP DOWN THE
CALIFORNIA COAST LATE-WEEKEND INTO EARLY NEXT WEEK, WHICH WILL
INCREASE PRECIPITATION CHANCES, INCREASE SOUTHWESTERLY WINDS, AND
DECREASE TEMPERATURES.
