KEY MESSAGES
* ANOMALOUS EARLY-SEASON HEAT CONTINUES THROUGH THE FORECAST PERIOD.
DISCUSSION
TODAY THROUGH FRIDAY.
A RIDGE OF HIGH PRESSURE PERSISTS OVER THE DESERT SOUTHWEST,
RESULTING IN CONTINUED ANOMALOUS EARLY-SEASON HEAT. A WEAK SHORTWAVE
WILL RIDE ALONG THE UPPER-LEVEL RIDGE TODAY, WHICH WILL BRING BREEZY
SOUTHWEST WINDS TO THE REGION AS WELL AS INCREASED CLOUD COVER MID-
TO-LATE AFTERNOON. THIS CLOUD COVER MAY ARRIVE LATE ENOUGH TO
PRODUCE LITTLE IN THE WAY OF RELIEF TO AFTERNOON HIGH TEMPERATURES
FOR THE MOJAVE DESERT, BUT SHOULD HELP COOL THE SOUTHERN GREAT BASIN
COMPARED TO THE LAST FEW DAYS. ADDITIONALLY, THIS CLOUD COVER WILL
TRAP THE HEAT OVERNIGHT, LIKELY RESULTING IN NUMEROUS RECORD WARM
MORNING LOWS. AFTERNOON TEMPERATURES COOL BY 3 TO 5 DEGREES ON
SUNDAY AND MONDAY... BUT WILL STILL REMAIN AROUND 30 DEGREES ABOVE
SEASONAL NORMALS. AS THE RIDGE REBOUNDS MID-WEEK, AFTERNOON HIGH
TEMPERATURES INCREASE ONCE AGAIN TO SIMILAR VALUES AS SEEN OVER THE
LAST FEW DAYS. THERE IS NO SUBSTANTIAL COOLDOWN EXPECTED IN AT LEAST
THE NEXT 7 DAYS.
AVIATION...FOR HARRY REID...FOR THE 12Z FORECAST PACKAGE
LIGHT
WINDS WILL CONTINUE THROUGH THE MORNING. INCREASING SOUTHWEST WINDS
ARE EXPECTED THIS AFTERNOON AFTER 18Z. GUSTS OVER 15KT ARE EXPECTED
WITH A 30% CHANCE FOR GUSTS OVER 20KT. WINDS WILL DIMINISH THIS
EVENING AS GUSTS END BUT WIND SPEEDS AT 8-10KT PERSIST UNTIL AROUND
12Z SUNDAY. LIGHT WINDS ARE THEN EXPECTED THROUGH SUNDAY MORNING.
CLEAR SKIES WILL GIVE WAY TO INCREASING CLOUD AT 20KFT LATE THIS
AFTERNOON AND TONIGHT.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 12Z FORECAST PACKAGE...LIGHT WINDS ARE EXPECTED
OVERNIGHT. BREEZY SOUTHWEST WINDS WILL DEVELOP THIS AFTERNOON ACROSS
THE WESTERN MOJAVE DESERT INTO SOUTHERN NEVADA AND WESTERN ARIZONA.
WIDESPREAD GUSTS OF 15-25KT ARE EXPECTED IN THIS AREA. ELSEWHERE,
LIGHT WINDS UNDER 10KT WILL CONTINUE THROUGH THE AFTERNOON. GUSTS
WILL DISSIPATE AFTER SUNSET AND TYPICAL OVERNIGHT WIND PATTERNS
SHOULD RETURN. INCREASING SCT-BKN CLOUDS AT OR ABOVE 15KFT FROM WEST
TO EAST ARE EXPECTED THROUGH THE TAF PERIOD.
