DISCUSSION
THROUGH THE END OF THE WEEK.
HEAT WILL PEAK ACROSS THE REGION TODAY WITH AFTERNOON HIGHS
CLIMBING 3-7 DEGREES ABOVE NORMAL, WITH A GRADUAL COOLING TREND
TUESDAY ONWARD. THE REMAINDER OF THE WEEK WILL FEATURE DECREASING
HEIGHTS AND INCREASING MID-LEVEL MOISTURE, RESULTING TEMPERATURES
RETURNING TO NEAR OR EVEN SLIGHTLY BELOW NORMAL. WHILE CONTINUED
WARMING IS ANTICIPATED TODAY, HEIGHTS WILL ACTUALLY BEGIN TO
DECREASE FROM THEIR VALUES SUNDAY, AND MAJORITY OF THE ADDED
WARMING IS THANKS TO ENHANCED SURFACE MIXING AND CONTINUED LOW
LEVEL WARMING. HOWEVER, TONIGHT'S GUIDANCE HAS SHAVED OFF A
DEGREE OR TWO OF EXPECTED HEAT FROM THE FORECAST, WHICH MAKES
SENSE GIVEN THE EXPECTATIONS OUTLINED ABOVE. AS SUCH, MODERATE
HEAT RISK IS EXPECTED ACROSS MOST OF THE DESERT TERRAIN, THOUGH
MAJOR HEAT RISK IS QUITE LIMITED. SUBTLE COOLING WILL BEGIN ON
TUESDAY WITH MORE PRONOUNCED SURFACE COOLING MIDWEEK.
MEANWHILE, STILL ANTICIPATING A PUSH OF LOW GRADE MONSOONAL
MOISTURE INTO THE REGION AS EARLY AS TUESDAY AFTERNOON ACROSS
NORTHWEST ARIZONA. LOW LEVELS WILL REMAIN QUITE DRY INITIALLY,
WHICH WILL POSE SOME RISK FOR DRY LIGHTNING STRIKES AND VERY
STRONG SURFACE WIND GUSTS WITH THE ACTIVITY THAT FORMS. MOISTURE
WILL DEEPEN WEDNESDAY AS CONTINUED MID-LEVEL MOISTURE ADVECTION
CREEPS WESTWARD AND INTERACTS WITH AN INCOMING LOW PRESSURE SYSTEM
OVER SOCAL. THIS WILL RESULT IN INCREASED STORM COVERAGE ACROSS
THE EASTERN MOJAVE DESERT AND FAR SOUTHERN NEVADA WEDNESDAY INTO
THURSDAY. AS THE SOCAL LOW LIFTS INLAND, DRIER SOUTHWESTERLY FLOW
WILL PUSH IN BY FRIDAY WITH DRY CONDITIONS RESUMING AND BREEZY
SOUTHWESTERLY WINDS.
