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.

15 KNOT SUSTAINED SOUTHWESTERLY WINDS GUSTING TO AROUND 20 TO 25

WILL CONTINUE THROUGH THE OVERNIGHT HOURS, INCREASING IN MAGNITUDE
LATE TUESDAY MORNING. THESE GUSTY SOUTHWESTERLY WINDS WILL

AN EXCEPTION, WITH NORTHWESTERLY WINDS EXPECTED TO SHIFT TO THE
