KEY MESSAGES
1. TEMPERATURES WILL GRADUALLY WARM THIS WEEK AND RISE BACK TO
AROUND 5 DEGREES ABOVE AVERAGE BY THE MIDDLE OF THE WEEK.
2. BREEZY CONDITIONS TAKE PLACE OVER TYPICAL WIND-PRONE AREAS
INCLUDING SAN LUIS RESERVOIR, LAKE ISABELLA AND THE MOJAVE
DESERT SLOPES THROUGH THIS WEEK.
DISCUSSION
WE WILL CONTINUE IN A GRADUAL WARMING TREND THIS WEEK WITH DRY
CONDITIONS THROUGH AT LEAST THE MIDDLE OF THE WEEK. HIGH
TEMPERATURES REMAIN IN THE 90S AT THE WARMEST VALLEY LOCATIONS
TODAY AS WELL AS THE NEXT FEW DAYS, BUT TRIPLE DIGIT HEAT IS IN
STORE FOR MUCH OF THIS WEEK IN THE MOJAVE DESERT. WE WILL BE
EDGING CLOSER TO THE CENTURY MARK AS WE PROGRESS INTO MIDWEEK.
THE BEST CHANCE FOR TRIPLE DIGIT HEAT IN THE SAN JOAQUIN VALLEY
WILL BE ON WEDNESDAY AND THURSDAY, OR AT 45-55 PERCENT FOR
FRESNO COUNTY SOUTHWARD AND MUCH LOWER CHANCES TOWARDS MADERA
AND MERCED COUNTIES (5-15 PERCENT). IN ADDITION, THERE WILL BE A
LOWERING TREND IN HUMIDITY AND OVERNIGHT RECOVERY WILL DECLINE
A LITTLE EACH NIGHT IN THE MOUNTAINS, FOOTHILLS, AND HIGHER
TERRAIN ADJACENT TO THE WEST SIDE OF THE SAN JOAQUIN VALLEY.
LATER THIS WEEK, AN UPTICK IN MONSOONAL MOISTURE OCCURS IN THE
HIGHER ELEVATIONS OF THE SIERRA NEVADA, MAINLY FRIDAY INTO NEXT
WEEKEND. THE RIDGE OF HIGH PRESSURE WILL BE CENTERED FROM THE
FOUR CORNERS REGION TO THE GREAT BASIN, SO FLOW WILL BECOME MORE
SOUTH-SOUTHEASTERLY. ON NEXT WEEKEND OR EARLY NEXT WEEK, THERE
IS A LOW CHANCE FOR REMNANTS OF A TROPICAL SYSTEM TO IMPACT OUR
AREA. OTHERWISE, TEMPERATURES WILL REMAIN STEADY AND RELATIVELY
WARM ACROSS THE REGION.
