MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
935 AM PDT SAT APR 27 2002

SYNOPSIS...AN UPPER LOW OVER THE PACIFIC NORTHWEST WILL DROP SOUTH 
ALONG THE WEST COAST TODAY AND SUNDAY. THIS WILL RESULT IN CONTINUED 
BREEZY AND COOL WEATHER FOR MOST OF THE REGION THROUGH THE WEEKEND. 
SCATTERED SHOWERS AND THUNDERSTORMS WILL REMAIN A THREAT ACROSS 
PARTS OF SOUTH CENTRAL NEVADA TODAY WITH DRIER CONDITIONS EXPECTED 
SUNDAY. 

DISCUSSION...LOW CLOUDS COULD BE SEEN ON SATELLITE IMAGERY ACROSS 
MUCH OF SOUTHERN NEVADA AND NORTHWEST ARIZONA THIS MORNING. THE 
850-700 MB RH FIELDS ON THE 12Z ETA AND AVN DEPICTED THE SITUATION 
FAIRLY WELL AND BOTH INDICATE IT WILL GRADUALLY LIFT TO THE 
NORTHEAST FOR SOME CLEARING BY AFTERNOON. THE UPPER LOW STRADDLING 
THE OREGON COAST WILL SLOWLY DROP SOUTH TODAY AND ENHANCE UPWARD 
MOTION OVER NYE AND LINCOLN COUNTIES TODAY FOR A MENTION OF SHOWERS 
AND ISOLATED THUNDERSTORMS AS PREVIOUSLY EXPECTED. UPDATED ZONES TO 
REFLECT THE LATEST SKY CONDITION TRENDS FOR TODAY.

BEYOND TODAY THE MAIN FOCUS WILL CENTER AROUND THE UPPER LOW NEAR 
THE WEST COAST. THE 12Z ETA WAS SIMILAR TO THE 06Z AVN IN BRINGING 
THE CENTER OF THE LOW NEAR SAN FRANCISCO BY MONDAY AFTERNOON. STILL 
LOOKS ON TRACK TO MOVE INLAND BY TUESDAY.

.LAS...NONE.
