MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
310 AM PDT SUN JUL 1 2001

SYNOPSIS...HIGH PRESSURE BUILDING OVER THE FOUR CORNERS REGION WILL 
ALLOW HOT CONDITIONS TO CONTINUE INTO THE EARLY PART OF THE WEEK. 
SUBTROPICAL MOISTURE WILL MOVE AROUND THE SOUTH SIDE OF THE HIGH AND 
INTO THE SOUTHERN GREAT BASIN AND MOJAVE DESERT AND PRODUCE A THREAT 
OF THUNDERSTORMS EACH AFTERNOON.

DISCUSSION...CLOUDS CONTINUE TO DEVELOP THIS MORNING OVER THE 
SOUTHERN CWA AS MID LEVEL MOISTURE WORKS INTO THE REGION. SOME LIGHT 
SHOWERS WERE REPORTED OVER WESTERN LAS VEGAS AROUND MIDNIGHT IN  
ASSOCIATION WITH AN UPPER LEVEL VORTMAX MOVING NORTH INTO LINCOLN 
COUNTY. THIS VORT WILL CONTINUE TO TRACK NORTH AND IS FORECAST TO BE 
OVER EASTERN UTAH BY 18Z. FOUR CORNERS HIGH REMAINS IN PLACE AND 
THIS IS HELPING TO DRAW UP MID LEVEL MONSOONAL MOISTURE. NOT A LOT 
OF DYNAMICS OVER THE REGION AND NOT A LOT IS EXPECTED OVER THE NEXT 
COUPLE OF DAYS. HOWEVER...WITH THE HOT TEMPERATURES AND ENOUGH MID 
LEVEL MOISTURE...A COUPLE OF THUNDERSTORMS MAY DEVELOP OVER AREAS OF 
MOHAVE COUNTY THIS AFTERNOON. HAVE GONE AHEAD AND ADDED THIS INTO 
THE FORECAST. THE SAME GOES WITH THE NORTHERN AREAS OF THE CWA. 
THERE MAY BE ENOUGH MOISTURE AVAILABLE OVER NORTHERN NYE AND LINCOLN 
COUNTIES ALONG WITH THE TYPICAL AFTERNOON LI'S AROUND 0 TO KICK OFF 
A THUNDERSTORM OR TWO. LOOKS AS IF THE MAJORITY OF THE LOWER LEVEL 
MOISTURE WILL ARRIVE IN THE AREA BY TUESDAY AND WEDNESDAY. THESE 
LOOK TO BE THE BEST DAYS FOR THUNDERSTORMS WITH HEAVY RAINFALL 
POTENTIAL. WILL ALSO HAVE TO WATCH FOR EMBEDDED VORTMAXES TO ROTATE 
THROUGH THE REGION. MODELS HAVE SHOWN A FEW OVER THE NEXT FEW 
DAYS...BUT MOST REMAIN WEAK. WILL GO AHEAD AND KEEP THE EXTENDED 
BROADBRUSHED WITH A CHANCE OF THUNDERSTORMS EACH DAY AS THE FOUR 
CORNERS HIGH REMAINS IN PLACE AND CONTINUES TO DRAW UP MOISTUREH FROM 
THE SOUTH.

.LAS....NONE.
