AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
230 AM MDT FRI JUN 3 2011

DISCUSSION...MUCH OF THE NEAR-TERM WILL BE DOMINATED BY A SHORT WAVE
RIDGE WITH WARM AND DRY CONDITIONS. EASTERN IDAHO WILL BE UNDER A
STEADY SOUTHERLY FLOW ALOFT OVER THE WEEKEND AND INTO MONDAY AS A
CUT-OFF LOW DROPS OFF THE CALIFORNIA COAST. THE PATTERN WILL CHANGE
AS THE UPPER LOW LIFTS ACROSS THE GREAT BASIN AND NORTHERN ROCKIES
ON MONDAY. THIS WILL BRING THE FIRST REAL CHANCE OF SHOWERS AND
ISOLATED THUNDERSTORMS TO THE REGION. GFS/ECMWF SHOWING SIMILAR
TRACKS OF THE UPPER LOW THROUGH TUESDAY. BY TUESDAY NIGHT...ANOTHER
UPPER LOW WILL DROP INTO THE PACIFIC NORTHWEST WITH THE COASTAL
STATES REMAINING UNDER THE INFLUENCE OF UPPER-LEVEL TROUGHING. THIS
SHOULD RESULT IN A SWING TO COOLER TEMPERATURES WITH INCREASING
CHANCES OF PRECIPITATION. ECMWF IS SLIGHTLY AHEAD OF THE GFS IN
TERMS OF TIMING OF THE UPPER LOW ON TUESDAY...BUT BOTH MODELS KEEP
EASTERN IDAHO UNDER THE INFLUENCE OF THIS LOW THROUGH THURSDAY. THE
00Z GEM DROPS THE LOW OVER WESTERN OREGON AND IS THE FURTHEST WEST
OF ALL MODELS IN THE TRACK OF THE LOW.  HINSBERGER
