KEY MESSAGES
* EXPECT ONE MORE DAY OF DRY, MILD, AND WARM WEATHER TOMORROW.
* A PATTERN SHIFT WILL BRING COOLER TEMPERATURES TO THE REGION OVER
THE WEEKEND AND NEXT WEEK.
DISCUSSION
THROUGH WEDNESDAY.
THE CURRENT PATTERN ALOFT FEATURES A RIDGE OVER THE SOUTHWESTERN
UNITED STATES, A WEAK DISTURBANCE OFF OF THE SOUTHERN CALIFORNIA
COAST, AND A SHORTWAVE MOVING INTO THE PACIFIC NORTHWEST. THE RIDGE
IS RESPONSIBLE FOR THE WARM AND DRY WEATHER OVER THE PAST WEEK.
EXPECT ONE MORE DAY OF PLEASANT CONDITIONS TOMORROW, INCLUDING
TEMPERATURES 5 TO 10 DEGREES ABOVE NORMAL FOR LATE NOVEMBER. HIGH
CLOUD COVER WILL CLEAR OUT OF THE AREA TOMORROW AS THE WEAK
DISTURBANCE DISSIPATES.
A CHANGE IN THE WEATHER PATTERN ARRIVES ON SATURDAY AS THE SHORTWAVE
OVER THE PACIFIC NORTHWEST MOVES SOUTHEAST THROUGH THE INTERMOUNTAIN
WEST, FOLLOWED CLOSELY BY ANOTHER SHORTWAVE ON SUNDAY. THE INLAND
TRACK OF THESE DISTURBANCES MEANS THAT THE INCOMING AIR WILL BE DRY
AND PRECIPITATION CHANCES ARE LOW (15 TO 20 PERCENT) AND LIMITED TO
NORTHERN LINCOLN/MOHAVE COUNTIES. THE MORE NOTABLE IMPACT WILL BE A
10 TO 15 DEGREE DECREASE IN TEMPERATURES BETWEEN FRIDAY AND MONDAY
AS 500 MB HEIGHTS ALOFT LOWER. FOR LAS VEGAS, THIS MEANS HIGH
TEMPERATURES IN THE UPPER 50S TO LOW 60S. NORTHWESTERLY FLOW BEHIND
THESE SHORTWAVES LEAVES THE DOOR OPEN FOR ADDITIONAL SYSTEMS TO MOVE
INTO THE REGION THROUGH THE WEEK. ONE MIDWEEK BRINGS THE POTENTIAL
FOR PRECIPITATION AND REENFORCEMENT OF COLD TEMPERATURES. DETAILS
WILL BECOME MORE APPARENT WITH UPCOMING FORECAST CYCLES - STAY
TUNED.
