* DRY CONDITIONS WILL CONTINUE AT LEAST THROUGH TUESDAY, BUT RENEWED
RAIN CHANCES ARRIVE NEW YEAR'S EVE ONWARD.
DISCUSSION
THROUGH SUNDAY. MIDNIGHT SATELLITE LOOP SHOWED MOSTLY
CLEAR SKIES AREAWIDE. SURFACE OBS SHOWED LOCALLY GUSTY NORTH WINDS,
STRONGEST IN AREAS OF FAVORED TERRAIN, TEMPERATURES SIMILAR TO 24
HOURS AGO AND DEWPOINTS SIGNIFICANTLY LOWER.
THE WINDS WILL BE THE MAIN CONCERN AGAIN TODAY. KATHERINE LANDING
AND BULLHEAD CITY GUSTED TO 40 MPH YESTERDAY, AND SIMILAR WINDS
SHOULD OCCUR AGAIN TODAY BEFORE SETTLING DOWN A LITTLE TONIGHT. THE
WIND ADVISORY LOOKS GOOD.
HIGH PRESSURE ALOFT WILL KEEP OUR WEATHER DRY FOR A FEW MORE DAYS,
BUT PERHAPS NOT QUITE AS LONG AS SOME WOULD PREFER. LOW PRESSURE WAS
SPINNING NEAR 20N 127W AT MIDNIGHT, WITH A SUBSTANTIAL PLUME OF
MOISTURE GETTING PULLED NORTHWARD AROUND ITS EASTERN SIDE. THOSE WHO
HAVE BEEN FOLLOWING ALONG WILL REMEMBER THAT TWO DAYS AGO A MAJORITY
OF MODEL SOLUTIONS SHOWED RAIN HOLDING OFF UNTIL AFTER THE MIDNIGHT
FESTIVITIES ON NEW YEAR'S EVE, BUT YESTERDAY, A MAJORITY SUGGESTED
RAIN REACHING LAS VEGAS BEFORE MIDNIGHT. TODAY, THERE IS EVEN MORE
SUPPORT FOR RAIN BEFORE MIDNIGHT, SO THE RUN TO RUN TRENDS SEEM
CLEAR. THE TRANSVERSE RANGES IN SOCAL SHOULD INTERCEPT A LOT OF
MOISTURE AND WRING IT OUT ON THE WINDWARD (SOUTH) SIDE, SO RAIN IN
OUR AREA WOULD MOST LIKELY BE LIGHT, BUT STILL ENOUGH TO MAKE
OUTDOOR REVELRY UNCOMFORTABLE. AS SHOULD BE EXPECTED, THERE ARE
INCREASING DIFFERENCES AMONG THE MODELS AT LONGER TIME RANGES, BUT
THERE IS REASONABLE CONSENSUS ON WEAK, DIRTY RIDGING FRIDAY FOLLOWED
BY SOME FLAVOR OF UNSETTLED WEATHER NEXT WEEKEND. TEMPERATURES
SHOULD BE NEAR TO SLIGHTLY ABOVE NORMAL THROUGH THE PERIOD.
AVIATION...FOR HARRY REID...FOR THE 18Z FORECAST PACKAGE

TAF PERIOD WITH INCREASING HIGH CLOUDS TONIGHT INTO TUESDAY.
FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 18Z FORECAST PACKAGE...WINDS OVER MOST AREAS
WILL PERSIST OUT OF THE NORTH TO NORTHEAST WITH WINDS 10-20KT

THROUGH 18Z. WINDS WILL DIMINISH THIS EVENING WITH LIGHT WINDS
