SYSTEM WILL DROP INTO THE REGION FROM THE PACIFIC NORTHWEST ON
TUESDAY, LINGERING OVER THE REGION THROUGH THURSDAY. GUSTY
SOUTHWESTERLY WINDS WILL PICK UP ACROSS THE MOJAVE DESERT AND
SOUTHERN GREAT BASIN ON TUESDAY IN RESPONSE TO THIS LOW PRESSURE
SYSTEM. TUESDAY'S WIND ADVISORY FOR THE WESTERN MOJAVE DESERT HAS
BEEN EXPANDED TO NYE COUNTY, ESMERALDA COUNTY, NORTHWESTERN CLARK

LINGER INTO THURSDAY ACROSS THE WESTERN MOJAVE DESERT IN THE BARSTOW
AREA. ELSEWHERE, BREEZY SOUTHERLY TO SOUTHWESTERLY WINDS WILL LINGER
INTO THURSDAY, BUT ARE NOT EXPECTED TO BE AS STRONG AS TUESDAY'S
WINDS.
IN ADDITION TO GUSTY WINDS, THIS SYSTEM WILL ALSO BRING COOLER THAN
NORMAL TEMPERATURES TO THE REGION, WITH TEMPERATURES FALLING AROUND
6 TO 12 DEGREES FROM TUESDAY TO WEDNESDAY. AS THE CENTER OF THIS LOW
