HIGH PRESSURE MAINTAINS ANOMALOUSLY HOT TEMPERATURES ACROSS THE
SOUTHWESTERN UNITED STATES THROUGH EARLY NEXT WEEK. TEMPERATURES
WILL BE 5 TO 10 DEGREES ABOVE NORMAL FOR LATE JULY THROUGH MONDAY,
WITH DAYTIME HIGHS IN THE 110S AND OVERNIGHT LOWS IN THE UPPER 80S
TO LOW 90S ACROSS MOST DESERT VALLEYS. NUMEROUS DAILY RECORD HIGH
TEMPERATURES AND WARM LOW TEMPERATURE RECORDS ARE IN JEOPARDY - SEE
THE CLIMATE SECTION BELOW FOR DETAILS. HOT DAYTIME TEMPERATURES AND
WARM OVERNIGHT TEMPERATURES THAT OFFER LITTLE RELIEF YIELD LARGE
SWATHS OF MAJOR (LEVEL 3 OF 4) TO EXTREME (LEVEL 4 OF 4) HEAT RISK
IN THE MOJAVE DESERT. TEMPERATURES BACK OFF A FEW DEGREES ON TUESDAY
AND WEDNESDAY AS THE RIDGE SHIFTS EAST AND HEIGHTS ALOFT FALL.
HOWEVER, PARTICULARLY DANGEROUS HEAT RETURNS THURSDAY THROUGH NEXT
WEEKEND AS THE RIDGE BUILDS BACK TO THE WEST. EXPECT WIDESPREAD
MAJOR TO EXTREME HEATRISK ACROSS SOUTHERN NEVADA, SOUTHEASTERN
CALIFORNIA, AND NORTHWESTERN ARIZONA AS THIS OCCURS.
BUILDING HIGH PRESSURE OVER THE SOUTHWESTERN UNITED STATES AND LOW
PRESSURE OVER THE PACIFIC NORTHWEST WILL LEAD TO DRY SOUTHWESTERLY
FLOW OVER THE FORECAST AREA. THIS PATTERN COMBINED WITH A LACK OF A
LIFTING MECHANISM BESIDES DAYTIME HEATING WILL INHIBIT CONVECTION
FOR MOST LOCATIONS THROUGH NEXT WEEK. NORTHWESTERN ARIZONA MAY STILL
BE ABLE TO TAP INTO SOUTHERLY MOISTURE FLOW AND THERE ARE LOW (10 TO
20 PERCENT) CHANCES OF AFTERNOON THUNDERSTORMS OVER HIGH TERRAIN,
ESPECIALLY ON TUESDAY AND WEDNESDAY.
