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.
