INCREASING MONSOONAL MOISTURE IN SOUTHEAST FLOW ALOFT WILL BRING A SLIGHT CHANCE OF THUNDERSTORMS WITH A FEW DRY LIGHTNING STRIKES AND STRONG OUTFLOW WINDS TO AROUND 45 MPH FOR THE MOUNTAINS AND DESERTS FOR THIS AFTERNOON AND EARLY EVENING. A CHANCE OF MAINLY AFTERNOON AND EARLY EVENING THUNDERSTORMS WITH WETTING RAINS WILL CONTINUE FOR THE MOUNTAINS AND DESERTS THROUGH AT LEAST SATURDAY AND POSSIBLY INTO EARLY NEXT WEEK. A SHALLOW MARINE LAYER WILL KEEP AREAS NEAR THE COAST COOLER WITH HIGHER HUMIDITIES. Discussion from LAXFWFLOX STRONG HIGH PRESSURE CENTERED OVER THE GREAT BASIN WILL GRADUALLY SHIFT SOUTHWEST AND ABOVE NORMAL TEMPERATURES WILL PERSIST OVER THE AREA. INLAND TEMPERATURES WILL LIKELY RANGE 10 TO 15 DEGREES ABOVE NORMAL THROUGH THURSDAY. SLIGHT COOLING IS EXPECTED FRIDAY AS THE RIDGE OF HIGH PRESSURE WEAKENS AND SHIFTS SOUTHWEST OF THE AREA. A COOLING TREND WILL CONTINUE SATURDAY THROUGH SUNDAY AND INLAND TEMPERATURES WILL LIKELY COOL TO SEASONAL NORMALS BY SATURDAY AND THEN 2 TO 4 DEGREES BELOW NORMAL SUNDAY. MONSOON MOISTURE WILL CONTINUE TO INCREASE OVER VENTURA AND LOS ANGELES COUNTIES THROUGH THURSDAY AND THEN GRADUALLY SHIFT EAST FRIDAY THROUGH SATURDAY. A SLIGHT CHANCE OF DRY LIGHTNING IS EXPECTED SOUTH AND EAST OF HIGHWAY 14 IN THE ANTELOPE VALLEY AND SAN GABRIEL MOUNTAINS THIS AFTERNOON. THE THREAT OF DRY LIGHTNING WILL LESSEN THURSDAY AS THE CHANCE OF WETTING RAIN INCREASES. THE THUNDERSTORMS ARE EXPECTED TO BE NEARLY STATIONARY OVER VENTURA AND LOS ANGELES MOUNTAINS THURSDAY EVENING. Discussion from SFOFWFHNX THE WARMING TREND WILL CONTINUE ACROSS THE DISTRICT TODAY AS A STRONG UPPER LEVEL RIDGE RESIDES OVER THE GREAT BASIN. THERE MAY BE ENOUGH MID LEVEL TROPICAL MOISTURE PULLED NORTHWARD INTO THE AREA TO PRODUCE ISOLATED DRY THUNDERSTORMS OVER THE MOUNTAINS THIS AFTERNOON AND EVENING. THUNDERSTORMS WILL BECOME WET AND MORE NUMEROUS THURSDAY THROUGH FRIDAY AS AN INFLUX OF DEEPER MONSOONAL MOISTURE OCCURS. OTHERWISE...TEMPERATURES WILL AVERAGE ABOVE NORMAL THROUGH THE WEEKEND. Discussion from RNOFWFVEF TEMPERATURES WILL REMAIN AT DANGEROUSLY HOT LEVELS TODAY AS STRONG HIGH PRESSURE STAYS OVER THE GREAT BASIN. INCREASING MONSOON MOISTURE WILL BRING A SLIGHT CHANCE OF THUNDERSTORMS TO MOST AREAS ON THURSDAY WITH BETTER COVERAGE OF THUNDERSTORMS ON FRIDAY AND SATURDAY. HIGH TEMPERATURES WILL BE BELOW NORMAL FRIDAY THROUGH THE WEEKEND WHILE HUMIDITY VALUES WILL BE ON THE RISE. Discussion from PHXFWFPSR SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP AGAIN TODAY...THIS TIME REACHING THE LOWER ARIZONA DESERTS AS WELL AS THE HIGHER TERRAIN EAST OF PHOENIX. SIMILAR STORM CHANCES ARE EXPECTED ON THURSDAY HOWEVER SOME STORMS COULD MAKE THEIR WAY INTO SOUTHEAST CALIFORNIA. GIVEN THE RECENT INCREASE IN MOISTURE...OVERNIGHT RECOVERY IS EXPECTED TO BE VERY GOOD. WINDS WILL FAVOR TYPICAL DIURNAL PATTERNS AND SHOULD BE RELATIVELY LIGHT EXCEPT IN AND NEAR THUNDERSTORMS. ...THUNDERSTORMS IMPLY GUSTY WINDS... NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN THE AREA FORECAST DISCUSSION.
