AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 314 AM MDT SAT AUG 4 2007 .SHORT TERM...SATURDAY THROUGH TUESDAY. VERY LITTLE CHANGE IN THE PATTERN OVER SOUTHEAST ID AS CWA REMAINS IN SOUTHWESTERLY FLOW REGIME WITH BROAD UPPER RIDGE TO THE EAST AND UPPER TROF DIGGING ALONG PACNW COAST. SPOTTY MONSOONAL MOISTURE WILL ROTATE ALONG THE WESTERN BOUNDARY OF THE UPPER RIDGE NEXT 48 TO 72 HRS TO PRODUCE ISOLATED THUNDERSTORMS EACH AFTN/EVE. EASTERN AND SOUTHERN HIGHLANDS ARE THE FAVORED LOCATION FOR CONVECTION ALTHOUGH A FEW CELLS MAY POP UP IN THE SNAKE PLAIN. BY LATE SUN/MON THE PACNW SYSTEM BEGINS TO SPLIT WITH A MODERATELY STRONG SHORTWAVE TROUGH MOVING ACROSS CENTRAL ID AND THE SOUTHERN PORTION CONTINUING TO DIG SOUTHWESTWARD WITH THE TROF BASE OUT TO AT LEAST 140W. MONSOONAL MOISTURE BEGINS TO THIN OUT ON MON/TUES SO HAVE DECREASED POPS FOR THOSE DAYS.
