DISCUSSION
THROUGH NEXT WEEKEND.
CONSIDERABLE HIGH CLOUD COVER HAS OVERSPREAD THE REGION THIS
AFTERNOON, RESTRAINING AFTERNOON TEMPS SLIGHTLY AND HERALDING A
MUCH ANTICIPATED RETURN TO COOLER TEMPERATURES. MID AND HIGH LEVEL
MOISTURE WILL CONTINUE TO STREAM INTO THE REGION TONIGHT INTO
TUESDAY, WITH OVERALL FAIRLY GLOOMY AND OVERCAST CONDITIONS
EXPECTED MOST OF THE DAY TUESDAY. BY THE AFTERNOON, MOISTURE WILL
BECOME DEEP ENOUGH FOR SOME LIGHT SHOWERS ACROSS THE SOUTHERN
GREAT BASIN AND NORTHWEST ARIZONA, AS WELL AS THE SIERRA AND
SPRING MOUNTAINS. LIGHTER PRECIPITATION AMOUNTS OF SPRINKLES OR A
HUNDREDTH OR TWO WILL BE POSSIBLE ACROSS THE DESERT VALLEYS AS
WELL, MAINLY NORTH OF I-40 DURING THE EVENING AND OVERNIGHT HOURS.
WHILE SOUTHWESTERLY SURFACE WINDS HAVE ALREADY BECOME FAIRLY
GUSTY ACROSS THE REGION TODAY, THEY WILL BECOME EVEN STRONGER
TUESDAY, WITH AFTERNOON GUSTS OF 35 TO 50 MPH ACROSS MUCH OF THE
MOJAVE DESERT EXTENDING EASTWARD INTO NORTHWEST ARIZONA. CLOUD
COVER TOMORROW MAY INITIALLY LIMIT MIXING AND KEEP WIND SPEEDS
MODERATED, BUT LIGHT VIRGA SHOWERS MAY CONVERSELY MIX LOW LEVEL
WINDS TO THE SURFACE. THERE IS ALSO THE POTENTIAL FOR SOME
DOWNSLOPE ENHANCEMENT ACROSS THE SOUTHERN OWENS VALLEY AND EAST OF
THE SPRING MOUNTAINS, WHERE GUSTS MAY LOCALLY EXCEED 50 MPH.
WINDS WILL GRADUALLY EASE OVERNIGHT.
AN ADDITIONAL SHORTWAVE WILL MOVE INTO THE PACNW THURSDAY WHICH
WILL RESULT IN ANOTHER ROUND OF GUSTY WINDS, ESPECIALLY ACROSS
THE WESTERN MOJAVE DESERT WHERE ECMWF METEOGRAMS FAVORING GUSTS
EXCEEDING 50 MPH THURSDAY AFTERNOON NEAR BARSTOW. THE SHORTWAVE
ITSELF LOOKS TO TREK EAST ACROSS THE GREAT BASIN, KEEPING
PRECIPITATION CHANCES LIMITED MAINLY TO AREAS NORTH OF OUR REGION.
TEMPERATURES WILL BOTTOM OUT FRIDAY BEFORE HIGH PRESSURE RIDGING
WILL BEGIN TO BUILD BACK OVER THE WEEKEND. THIS WILL ALLOW
TEMPERATURES TO GRADUALLY CLIMB, THOUGH GUSTY NORTH WINDS WILL
PERSIST ALONG THE COLORADO RIVER VALLEY.
AVIATION...FOR HARRY REID
FOR THE 06Z FORECAST
PACKAGE...ELEVATED SOUTH TO SOUTHWEST WINDS WILL PERSIST THROUGH THE
NIGHT AS GUSTS 20-25KT CONTINUE. WINDS MAY TURN MORE WESTERLY
BETWEEN 07Z-12Z, IF THEY DON'T THEN THE WILL REMAIN MORE SOUTH
GUSTING TO 20KT AT TIMES. STRONG SOUTHWEST WINDS ARE EXPECTED ON
TUESDAY AS GUSTS OVER 30KT ARE LIKELY (70% CHANCE) BETWEEN 18Z AND
00Z. THERE IS A 30% CHANCE FOR GUSTS OVER 35KT, MAINLY AFTER 21Z.
WINDS WILL DIMINISH SLIGHTLY AFTER SUNSET BUT SOUTHERLY GUSTS OVER
20KT ARE EXPECTED THROUGH MUCH OF THE NIGHT. MODERATE CONFIDENCE
THAT WINDS WILL STOP GUSTING AND MAY EVEN BECOME LIGHT BY 12Z
WEDNESDAY. MOST LIKELY, IT WILL REMAIN DRY THROUGH THE TAF PERIOD
WITH ANY RAIN REMAINING IN THE MOUNTAINS. IF RAIN WERE TO MAKE IT
NEAR THE TERMINALS, IT WOULD BE AROUND 12Z. CIGS TO 8000FT WOULD BE
POSSIBLE WITH ANY RAIN. OTHERWISE, BKN TO OVC CIGS ARE EXPECTED
THROUGH TUESDAY NIGHT, LOWERING TO 12KFT BY TUESDAY AFTERNOON.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 06Z FORECAST PACKAGE...WINDS SHOULD DIMINISH
SOMEWHAT TONIGHT AS SPEEDS DROP TO AROUND 10KT. ON TUESDAY, GUSTY
SOUTHWEST WINDS WILL DEVELOP ACROSS MUCH OF THE REGION. EXPECT
WIDESPREAD GUSTS OF 25-35KT BY TUESDAY AFTERNOON. THE STRONGEST
WINDS WILL BE IN THE WESTERN MOJAVE DESERT WHERE GUSTS UP TO 40KT
ARE POSSIBLE. THE OWENS VALLEY AND KBIH MAY NOT SEE THE WEST TO
SOUTHWEST GUSTS UNTIL AFTER 21Z. WINDS WILL DROP BACK AFTER SUNSET
BUT REMAIN GUSTY OUT OF THE WEST TO SOUTHWEST IN MOST LOCATIONS AS
GUSTS 20-30KT CONTINUE THROUGH THE NIGHT. LIGHTER WINDS ARE EXPECTED
IN THE COLORADO RIVER VALLEY TUESDAY NIGHT. PRECIPITATION WILL
SPREAD ACROSS THE REGION TUESDAY, MAINLY FAVORING THE TERRAIN UNTIL
SPILLING INTO THE SOUTHERN GREAT BASIN TUESDAY NIGHT. CIGS TO 7000FT

GUSTY WINDS AT TIMES IN THE AFTERNOON.
