AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 435 AM PDT TUE SEP 2 2003 .SYNOPSIS...HIGH PRESSURE NEAR THE FOUR CORNERS WILL KEEP MONSOON MOISTURE OVER THE AREA THROUGH WEDNESDAY. THIS WILL RESULT IN A CHANCE OF THUNDERSTORMS...MAINLY IN THE AFTERNOON AND EVENINGS. && .SHORT TERM...UPPER HIGH NEAR THE FOUR CORNERS THIS MORNING WITH A DECENT AMOUNT OF MOISTURE BEING PUSHED UP INTO THE MOJAVE DESERT AND TO SOME EXTENT THE SOUTHERN GREAT BASIN. ILL-DEFINED DISTURBANCE OVER ARIZONA HAS BEEN KEEPING THE THUNDERSTORMS GOING ALL NIGHT IN THE SOUTHEAST PORTION OF THE FORECAST AREA AND WILL PROBABLY CONTRIBUTE TO MORE ACTIVITY DURING THE DAY. AIRMASS OVER MOST OF THE FORECAST AREA IS PROGGED TO BECOME FAIRLY MOIST AND UNSTABLE TODAY ALTHOUGH THE MODELS SHOW THE FAR NORTHERN AREAS A BIT MORE STABLE. WILL GO WITH A CHANCE OF THUNDERSTORMS TODAY EXCEPT ONLY A SLIGHT CHANCE FAR NORTH. AS THE UPPER HIGH MIGRATES SLOWLY TO THE WEST...I EXPECT THE MOISTURE ALREADY IN PLACE TO JUST CONTINUE TO RECIRCULATE UNDER THE HIGH AND KEEP THE FORECAST AREA UNDER A CHANCE OR SLIGHT CHANCE OF THUNDERSTORMS THROUGH THURSDAY. && .LONG TERM...MOISTURE SHOULD BE MOVING OUT OF AREA ON FRIDAY AS THE UPPER HIGH MOVES SOUTH AND WEST TO OFF BAJA AND WESTERLY FLOW STARTS TO OCCUR. HAVE TRIMMED DOWN POPS IN WESTERN PART OF CWA. BELIEVE PRECIPITATION WILL BE AROUND FRIDAY AND SATURDAY IN THE EAST DUE TO RESIDUAL MOISTURE IN THE LOW LEVELS AND A JET MAX NOSING IN ON FRIDAY. BY SUNDAY EXPECT WEAK RIDING TO ZONAL FLOW IN THE AREA AHEAD OF AN APPROACHING PACIFIC TROUGH / FRONT. MODELS DIFFER IN THE DETAILS BUT AGREE ON THE GENERAL IDEA. GFS APPEARS THE FASTEST WITH THE SYSTEM. WENT ALONG WITH SOME TEMPERATURE DROPS MONDAY. HAVE KEPT IT DRY AS SOUTHWEST FLOW AHEAD OF SYSTEM WILL DRY AREA OUT. THAT BEING SAID I AM LEARY OF SEEING SUCH A STRONG PUSH OF COLD AIR THIS EARLY. WILL LET NEXT SHIFTS DECIDE IF THEY WANT TO LOWER TEMPERATURES MORE AND PICK UP THE WINDS THAT SUCH A FRONT WOULD BRING. && .LAS...NONE. && HARRISON/JACQUES
