KEY MESSAGES

UPCOMING WEEK.

DISCUSSION
THROUGH SUNDAY.
A RIDGE OVER THE SOUTHWESTERN UNITED STATES MAINTAINS WARM AND DRY
CONDITIONS FOR MOST OF THE AREA THROUGH THE END OF THE WEEK. HIGH
TEMPERATURES WILL BE 10 TO 15 DEGREES ABOVE AVERAGE FOR THIS TIME OF
YEAR AT MOST LOCATIONS. DAILY TEMPERATURE RECORDS WILL BE IN
JEOPARDY FOR MANY REGIONAL CLIMATE SITES - SEE THE CLIMATE SECTION
BELOW FOR MORE DETAILS. MEANWHILE, LOW SUN ANGLES AND LIGHT SURFACE
WINDS PROMOTE INVERSIONS IN CERTAIN NARROW VALLEYS INCLUDING DEATH
VALLEY, WHICH MEANS TEMPERATURES WILL STAY RELATIVELY COOL FOR THOSE
LOCATIONS THROUGH AT LEAST MIDWEEK.
ZONAL FLOW DEVELOPS ALOFT LATER THIS WEEK AS A SYSTEM MOVES INTO THE
PACIFIC NORTHWEST AND THE RIDGE OVER THE SOUTHWEST DEAMPLIFIES. THIS
PATTERN ALLOWS FOR IMPROVED MOISTURE ADVECTION AND INCREASING
PRECIPITATION CHANCES THIS WEEKEND, MOSTLY IN INYO AND ESMERALDA
COUNTIES. THE REST OF THE FORECAST AREA SHOULD REMAIN DRY WITH AN
INCREASE IN HIGH CLOUDS.
