KEY MESSAGES
* A BUILDING AREA OF HIGH PRESSURE WILL RESULT IN HOT TEMPERATURES
AND INCREASING HEAT RISK THROUGH THE END OF THE WEEK
* TROPICAL MOISTURE MAY INCREASE THIS WEEKEND LEADING TO A SLIGHT
CHANCE OF SHOWERS AND THUNDERSTORMS OVER PORTIONS OF NORTHWEST
ARIZONA.
DISCUSSION
TODAY THROUGH TUESDAY.
HIGH PRESSURE BUILDS OVER THE WESTERN UNITED STATES THROUGH THE END
OF THE WEEK AND SURFACE TEMPERATURES WILL RISE IN RESPONSE. HIGH
TEMPERATURES PEAK ON SATURDAY BETWEEN 5 AND 10 DEGREES ABOVE NORMAL
FOR MID-JUNE. FOR LAS VEGAS, THIS MEANS AFTERNOON HIGHS IN THE
UPPER 100S AND MORNING LOWS IN THE LOW TO MID 80S. A COMBINATION
OF HOT DAYTIME TEMPERATURES AND WARM OVERNIGHT LOWS WILL BRING
WIDESPREAD MODERATE (LEVEL 2 OF 4) HEAT RISK TO MOST OF THE
REGION, ALONG WITH AREAS OF MAJOR (LEVEL 3 OF 4) TO CERTAIN
VALLEYS, INCLUDING DEATH VALLEY, THE COLORADO RIVER VALLEY, AND
THE LAS VEGAS VALLEY BETWEEN FRIDAY AND SUNDAY. THIS LEVEL OF HEAT
WILL AFFECT ANYONE WITHOUT ACCESS TO SUFFICIENT COOLING AND
HYDRATION, ESPECIALLY THOSE SPENDING TIME OUTDOORS.
ALSO TRACKING A PLUME OF MOISTURE ORIGINATING FROM TROPICAL STORM
CRISTINA AND THE REMNANTS OF TROPICAL STORM BORIS. ENSEMBLES
INDICATE THIS MOISTURE TRAVELING UP THE GULF OF CALIFORNIA INTO THE
DESERT SOUTHWEST THIS WEEKEND, DRIVING PWATS TO BETWEEN 150 AND 200
PERCENT ABOVE NORMAL FOR THIS TIME OF YEAR. THIS MOISTURE MAY
PRODUCE ENOUGH HIGH CLOUD COVER TO HELP MODERATE TEMPERATURES.
ISOLATED SHOWERS AND THUNDERSTORMS CANNOT BE RULED OUT EITHER,
ESPECIALLY OVER HIGH TERRAIN IN NORTHWESTERN ARIZONA.
