KEY MESSAGES
* GENERALLY QUIET WEATHER THROUGH THE FORECAST PERIOD, WITH THE
EXCEPTION OF A SIGNIFICANT WARMING TREND, WHICH WILL INCREASE
TEMPERATURES TO NEAR-20 DEGREES ABOVE-NORMAL.
DISCUSSION
TODAY THROUGH SUNDAY.
THE AREA OF LOW PRESSURE THAT BROUGHT GUSTY CONDITIONS TO THE REGION
LAST WEEK WILL FINALLY PUSH INLAND INTO NORTHERN MEXICO TODAY. AS IT
PUSHES EASTWARD, BETWEEN 0.50 AND 0.75 INCHES OF PWAT WILL SURGE
NORTHWARD INTO OUR FAR SOUTHERN ZONES. AS A RESULT, THERE IS AROUND
A 20 PERCENT CHANCE OF ISOLATED SHOWERS AND THUNDERSTORMS IN FAR
SOUTHERN MOHAVE COUNTY THIS AFTERNOON AND EVENING INCLUDING THE
LOWER COLORADO RIVER VALLEY. OTHERWISE, QUIET AND DRY CONDITIONS ARE
EXPECTED THROUGH THE REST OF THE WORK WEEK AND INTO THIS WEEKEND.
THE MOST NOTABLE WEATHER WILL BE THE SIGNIFICANT WARMING TREND. A
RIDGE OF HIGH PRESSURE WILL BUILD ACROSS THE WESTERN UNITED STATES
THROUGH THE REMAINDER OF THE WEEK, WHICH WILL ALLOW TEMPERATURES TO
SOAR TO NEAR-20 DEGREES ABOVE SEASONAL NORMALS. THESE TEMPERATURES
WILL YIELD MINOR HEATRISK ACROSS DESERT VALLEYS, WITH THE EXCEPTION
OF DEATH VALLEY AND THE COLORADO RIVER VALLEY, WHERE HEATRISK WILL
INCREASE TO MODERATE. TEMPERATURES WILL CONTINUE TO CLIMB THROUGH
THE WEEKEND INTO NEXT WEEK AS THE RIDGE OF HIGH PRESSURE CENTERS
OVERHEAD. WITH SPRING BREAK ACROSS MUCH OF CLARK COUNTY NEXT WEEK
COUPLED WITH TYPICAL TOURISM RATES, THESE POTENTIALLY RECORD-
BREAKING TEMPERATURES WILL WARRANT INCREASED HEAT SAFETY MESSAGING
AS WE MOVE THROUGH THE FORECAST PERIOD.
