..DISCUSSION FROM RNOFWFVEF
HOT AND DRY CONDITIONS CONTINUE TODAY AND TOMORROW WITH MINIMUM
HUMIDITY IN THE SINGLE DIGITS TO LOW TEENS FOR MOST LOCATIONS. A
SIGNIFICANT CHANGE IN THE WEATHER PATTERN ARRIVES EARLY NEXT WEEK
AS TROPICAL MOISTURE MOVES INTO THE REGION. TEMPERATURES RETURN TO
BELOW AVERAGE VALUES AND MINIMUM HUMIDITY INCREASES TO THE 15 TO
30 PERCENT RANGE. UNCERTAINTY REMAINS IN THE TIMING AND MAGNITUDE OF
PRECIPITATION, BUT THE HIGHEST CONFIDENCE FOR WIDESPREAD
PRECIPITATION IS IN NORTHWESTERN ARIZONA ON SUNDAY AND SUNDAY
NIGHT.
..DISCUSSION FROM LAXFWFSGX
SEVERAL DEGREES WARMER TODAY FOR INLAND AREAS. A WEAK UPPER LEVEL
LOW PRESSURE SYSTEM OFF THE BAJA COAST WILL DRAW SOME TROPICAL
MOISTURE NORTHWARD INTO THE AREA FOR THE WEEKEND. SOME LIGHTER
SHOWERS COULD OCCUR AS EARLY AS SATURDAY, BUT THE MOST LIKELY TIME
FOR MORE WIDESPREAD SHOWERS IS FOR SUNDAY AFTERNOON AND EVENING
ALONG WITH A SLIGHT CHANCE OF THUNDERSTORMS. CHANCES FOR WETTING
RAINFALL RANGE AROUND 10 PERCENT FOR ORANGE COUNTY TO AROUND
50 PERCENT FOR THE MOUNTAINS AND SAN DIEGO COUNTY DESERTS. THERE
WILL BE A COOLING TREND FOR SATURDAY THROUGH TUESDAY WITH A DEEPER
MARINE LAYER FOR EARLY NEXT WEEK. THEN DRY WITH WARMING FOR
WEDNESDAY AND THURSDAY.
..DISCUSSION FROM PHXFWFPSR
AFTER A HOT AND SEASONABLY DRY DAY TODAY, MOISTURE WILL DRAMATICALLY
INCREASE OVER THE WEEKEND AS A WEATHER SYSTEM MOVES THROUGH THE
REGION. EXPECT MINRHS AROUND 8 TO 15 PERCENT TODAY BEFORE RHS
QUICKLY INCREASE THIS WEEKEND. VERY GOOD CHANCES FOR RAIN WILL
EXIST FROM SATURDAY NIGHT THROUGH SUNDAY NIGHT, WITH A 20-30%
CHANCE FOR THUNDERSTORMS ON SUNDAY. WINDS WILL FAVOR TYPICAL
DIURNAL TENDENCIES THROUGH SATURDAY WITH SOME BREEZY WINDS THIS
EVENING. WINDS SUNDAY SHOULD ALSO BE BREEZY AT TIMES WITH SHOWER
AND THUNDERSTORM ACTIVITY LIKELY INFLUENCING WINDS.
