.SYNOPSIS...LOW PRESSURE WILL SLOWLY MOVE AWAY TO THE SOUTHEAST ON
SATURDAY...ALLOWING DRY AIR TO MOVE IN FROM THE NORTHWEST. SKIES ARE
EXPECTED TO BE CLEAR AREAWIDE BY SATURDAY NIGHT...WITH THE
POSSIBILITY OF SOME PATCHY FOG MONDAY MORNING. DRY WEATHER IS
EXPECTED FOR NEXT WEEK WITH TEMPERATURES WELL ABOVE NORMAL.
&&

.SHORT TERM...THROUGH SATURDAY NIGHT...LOW PRESSURE WAS NEARLY
STATIONARY OVER FAR SOUTHERN NEVADA THIS AFTERNOON. RAIN HAD BEGUN
TO BREAK UP OVER MUCH OF THE AREA SINCE NOON. HIGH RESOLUTION MODELS
SUGGEST ANOTHER ROUND OF PRECIP OVERNIGHT AS THE LOW STARTS TO
MOVE...SO WILL STICK WITH HIGH POPS OVERNIGHT BUT LOWERED THE
AMOUNTS SOMEWHAT. HIGH PRESSURE NOSING IN FROM THE NORTHWEST
TOMORROW WILL SUPPRESS THE LOW TO THE SOUTHEAST...WITH PRECIP
CHANCES AND CLOUDS DECREASING FROM NORTHWEST TO SOUTHEAST. MOST
AREAS SHOULD SEE CLEAR OR MOSTLY CLEAR SKIES BY SATURDAY
NIGHT...LEADING TO THE POTENTIAL FOR PATCHY FOG EARLY SUNDAY MORNING
IN AREAS WHICH GOT SIGNIFICANT RAIN TODAY. GUSTY NORTH WINDS WILL BE
AN ISSUE SATURDAY...WITH THE STRONGEST GUSTS IN THE MOUNTAINS AND IN
NORTH SOUTH ORIENTED VALLEYS SUCH AS THE COLORADO RIVER VALLEY. DID
NOT ISSUE ANY WIND ADVISORIES AT THIS TIME BUT NIGHT CREW WILL NEED
TO TAKE A CLOSE LOOK.

.LONG TERM...SUNDAY THROUGH FRIDAY.

THE UPPER LOW RESPONSIBLE FOR THE RAIN WILL PUSH SOUTH SUNDAY AS
HIGH PRESSURE BUILDS IN FROM THE WEST. THERE WILL STILL BE SOME
LOWER LEVEL RESIDUAL MOISTURE HANGING AROUND SUNDAY MORNING AND
PATCHY FOG WILL BE POSSIBLE...BUT BY SUNDAY AFTERNOON DRIER AIR WILL
BE WORKING INTO THE AREA. HIGH PRESSURE WILL THEN BE IN CONTROL FOR
THE REMAINDER OF THE WEEK WITH JUST A COUPLE OF MINOR WEAK
SHORTWAVES MOVING OVER THE TOP OF THE RIDGE. THESE SYSTEMS DO NOT
LOOK TO IMPACT OUR WEATHER OTHER THAN VARIABLE HIGH CLOUDS AT TIMES
THROUGH THE WEEK. ABOVE NORMAL TEMPERATURES CAN BE EXPECTED THROUGH
THE WEEK WITH READINGS BY WEEKS END CLOSE TO 10 DEGREES ABOVE
NORMAL.
&&

.AVIATION...FOR MCCARRAN...RAIN CHANCES AND LOWER CEILINGS WILL
CONTINUE THROUGH THE NIGHT...WITH IMPROVING CONDITIONS EXPECTED ON
SATURDAY...ESPECIALLY AFTER NOON. NORTH WINDS COULD CAUSE RUNWAY
CONFIGURATION ISSUES ON SATURDAY. MUCH BETTER WEATHER IS EXPECTED
FROM SUNDAY ONWARDS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...RAIN CHANCES...LOWER CEILINGS...AND MOUNTAIN
OBSCURATION WILL CONTINUE THROUGH THE NIGHT. CONDITIONS WILL IMPROVE
FROM NORTHWEST TO SOUTHEAST SATURDAY INTO SATURDAY NIGHT...WITH
GUSTY NORTH WINDS EXPECTED OVER MUCH OF THE AREA. MUCH BETTER
WEATHER IS EXPECTED FROM SUNDAY ONWARDS.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED
AT THIS TIME. SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT RAIN
OR SNOW.
