..DISCUSSION FROM LOS ANGELES/OXNARD
 
 
...AN EXTENDED PERIOD OF VERY WARM CONDITIONS OVER VALLEYS AND  
MOUNTAINS WILL BRING ELEVATED FIRE DANGER THIS WEEK...  
 
...SLIGHT CHANCE OF AFTERNOON THUNDERSTORMS OVER INTERIOR VENTURA  
AND LOS ANGELES COUNTIES THROUGH AT LEAST THURSDAY...  
 
A STRONG UPPER LEVEL HIGH PRESSURE SYSTEM WILL REMAIN CENTERED OVER  
THE FOUR CORNERS REGION THROUGH MOST OF THE WEEK. VERY WARM  
CONDITIONS WILL PERSIST THROUGH THE WEEK OVER THE VALLEYS AND  
MOUNTAINS AS A RESULT, WITH DAILY MAX AND MIN TEMPERATURES 5 TO 10  
DEGREES ABOVE NORMAL. TUESDAY AND WEDNESDAY LOOK THE HOTTEST WITH  
POTENTIAL HEAT RISK ISSUES. COASTAL AREAS SHOULD REMAIN INFLUENCED  
BY A SHALLOW MARINE LAYER WITH DENSE FOG ISSUES. WINDS WILL BE  
FAIRLY SEASONAL WITH OCCASIONALLY BREEZY ONSHORE WINDS OVER THE  
LOWER ELEVATION INTERIOR AREAS. WITH THE POSITION OF THE HIGH,  
MOIST SOUTHEAST FLOW ALOFT HAS BROUGHT SUB-TROPICAL MOISTURE TO THE  
REGION. THIS WILL MINIMIZE THE RISK OF VERY LOW HUMIDITIES WITH THE  
HEAT, BUT BRING THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS. WHILE  
SHOWERS AND THUNDERSTORMS COULD FORM ANYWHERE THIS MORNING, THE  
FOCUS THIS AFTERNOON AND FOR THE REST OF THE PERIOD WILL BE INTERIOR  
LOS ANGELES AND VENTURA COUNTIES. WHILE THERE IS A SMALL RISK FOR  
DRY LIGHTNING TODAY, THAT POTENTIAL WILL DECREASE BY THIS AFTERNOON  
AS THE CONCERN FOR MODERATE TO HEAVY RAIN INCREASES.  
 
   
..DISCUSSION FROM MONTEREY
 
 
BUILDING HIGH PRESSURE EAST OF THE REGION WILL RESULT IN A WARMING  
AND DRYING TREND ACROSS THE MARINE LAYER COMPRESSES ALONG THE  
COAST. WINDS WILL REMAIN ONSHORE ALLOWING FOR NIGHTLY INTRUSIONS OF  
COASTAL LOW CLOUDS AND FOG INTO THE VALLEYS. ABOVE THE MARINE  
LAYER, HUMIDITY RECOVERY WILL BECOME POOR TO MODERATE AT NIGHT  
ALLOWING THE FINE FUELS TO CONTINUE TO DRY OUT. THE LONG RANGE  
TRENDS SUGGEST THAT HIGH PRESSURE WILL PERSIST OVER THE REGION WITH  
CONTINUED DRY AND WARM WEATHER. AT THIS TIME, DRY WEATHER  
CONDITIONS WILL ALSO PREVAIL.  
 
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.  
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
