KEY MESSAGES
* WELL ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH TUESDAY
BEFORE DECREASING DURING THE SECOND HALF OF THE WEEK, ALTHOUGH
TEMPERATURES WILL REMAIN SEVERAL DEGREES ABOVE NORMAL.
DISCUSSION
TODAY THROUGH NEXT MONDAY.
WELL ABOVE NORMAL TEMPERATURES WILL REMAIN THE MAIN WEATHER CONCERN
TODAY AND TUESDAY, WITH READINGS PEAKING 12 TO 16 DEGREES ABOVE
NORMAL ACROSS MUCH OF THE REGION AS A RIDGE OF HIGH PRESSURE REMAINS
IN PLACE. THIS WILL RESULT IN MODERATE HEATRISK (LEVEL 2 OUT OF 4)
ACROSS THE SOUTHERN HALF OF THE FORECAST AREA THROUGH TUESDAY,
INCLUDING LAS VEGAS, KINGMAN, BARSTOW, AND TWENTYNINE PALMS. AREAS
OF MAJOR HEATRISK (LEVEL 3 OUT OF 4) ARE EXPECTED IN THE LOWER
DESERT VALLEYS, INCLUDING DEATH VALLEY, LAUGHLIN, AND LAKE HAVASU.
THE RIDGE WILL BEGIN TO WEAKEN SLIGHTLY AND SHIFT EASTWARD FROM
MIDWEEK ONWARD, AS A QUICK MOVING SHORTWAVE PUSHES THROUGH THE GREAT
BASIN. THIS WILL INCREASE AFTERNOON WINDS AND BRING A SLIGHT COOLING
TREND FROM MIDWEEK ONWARD, ALTHOUGH TEMPERATURES WILL STILL REMAIN
SEVERAL DEGREES ABOVE NORMAL. A GENERALLY ZONAL FLOW PATTERN WILL
CONTINUE THROUGH NEXT WEEKEND, ALLOWING WARM AND DRY CONDITIONS TO
PERSIST.
