SYNOPSIS
 
MOSTLY SUNNY SKIES AND DRY CONDITIONS ARE  
LIKELY THROUGH THE WEEK. WINDS WILL BE ON THE DECREASE BUT  
TEMPERATURES WILL BE ON THE INCREASE THROUGH THE MIDDLE OF THE WEEK.  
AFTER THAT, TEMPERATURES WILL RETREAT ONLY A FEW DEGREES THROUGH THE  
WEEKEND.  
 

 
   
DISCUSSION
 
THROUGH SUNDAY.  
 
ANOTHER AREA OF HIGH CLOUDS IS IN THE PROCESS OF DEVELOPING OVER  
SOUTHERN INYO COUNTY THIS MORNING. HREF HIGH CLOUD COVER DATA SHOWS  
THIS AREA WILL LIFT NORTH ACROSS INYO, NYE, ESMERALDA AND LINCOLN  
COUNTIES THROUGHOUT THE DAY. OTHERWISE, THIS AUGUST 'NONSOON'  
CONTINUES WITH DRY CONDITIONS AND ABOVE NORMAL TEMPERATURES TODAY. A  
FEW ONGOING WILDFIRES AROUND THE REGION MAY PRODUCE LOCALIZED SPOTS  
OF SMOKE OR HAZE.  
 
TUESDAY-THURSDAY: AREA WILL EXPERIENCE ANOTHER ROUND OF HEAT. STRONG  
MID-LEVEL RIDGE TO OUR EAST IS PROGGED TO SHIFT WEST DURING THE  
MIDDLE OF THE WEEK. HIGH TEMPERATURES WILL BE SOME 6-8 DEGREES ABOVE  
NORMAL ON WEDNESDAY WHICH WILL BE THREATENING SOME RECORDS. LITTLE  
RELIEF INTO THURSDAY WITH OUR EXCESSIVE HEAT WARNING RUNNING THROUGH  
THURSDAY EVENING.  
 
FRIDAY-SUNDAY: LITTLE RELIEF EXPECTED OVER THE WEEKEND WITH  
EXPANSIVE AREA OF HIGH PRESSURE STAYING INTACT OVER NORTHERN  
CALIFORNIA AND THE GREAT BASIN. TEMPERATURES WILL BE ABOUT 5 DEGREES  
ABOVE NORMAL. MODELS STILL SHOWING A TROPICAL CYCLONE DEVELOPING IN  
THE EASTERN PACIFIC LATER THIS WEEK. MODELS CONTINUE TO SHOW THIS  
CYCLONE MOVING NORTHWEST TO NEAR THE BAJA PENINSULA THIS WEEKEND.  
HOWEVER, THE ORIENTATION OF THE RIDGE OVER THE GREAT BASIN LOOKS TO  
INHIBIT ANY SIGNIFICANT SURGE OF MOISTURE INTO OUR AREA AT THIS  
TIME.  
 

 
   
FIRE WEATHER
 
DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES WILL  
CONTINUE THROUGH THE WEEK. MINIMUM HUMIDITIES WILL LIKELY CONTINUE  
TO DROP INTO THE SINGLE DIGITS IN THE AFTERNOONS WITH POOR RECOVERY  
OVERNIGHT. THERE WILL BE A SHALLOW INCREASE IN LOW LEVEL MOISTURE  
INTO SOUTHEAST CALIFORNIA AND SOUTHERN MOHAVE COUNTY FRIDAY AND  
BEYOND LEADING TO BETTER HUMIDITY RECOVERY.
