THE WARMING TREND WILL CONTINUE THROUGH WEDNESDAY. MID-LEVEL

SHOWERS AND THUNDERSTORMS THIS AFTERNOON THROUGH WEDNESDAY
AFTERNOON FOR THE MOUNTAINS OF SAN BERNARDINO AND RIVERSIDE
COUNTIES EAST AND NORTHEASTWARD ACROSS THE DESERTS OF SOUTHERN
CALIFORNIA. LITTLE IF ANY RAINFALL WILL REACH THE GROUND AND ANY
THUNDERSTORMS THAT DEVELOP COULD PRODUCE DRY LIGHTNING STRIKES AND
LOCALLY GUSTY AND ERRATIC WINDS. DRY LIGHTNING STRIKES COULD RESULT
IN FIRE STARTS THAT HAVE THE POTENTIAL FOR INITIALLY RAPID GROWTH.
ONSHORE FLOW WILL STRENGTHEN FOR THURSDAY INTO THE WEEKEND, WITH
SUNDAY HIGH TEMPERATURES COOLING TO AS MUCH AS 10 TO 15 DEGREES
