AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
236 PM MDT MON JUN 6 2011
.SHORT TERM...TONIGHT THROUGH WEDNESDAY...GOOD SHEAR/INSTABILITY
AHEAD OF UPPER LOW...WHICH IS CENTERED OVER NORTHERN NV...WILL
SUPPORT ISOLATED STRONG-SEVERE THUNDERSTORMS IN PORTIONS OF SW IDAHO
THROUGH EARLY THIS EVENING BASICALLY EAST OF A MCCALL-MOUNTAIN HOME
LINE. MAIN CONCERN WILL CONTINUE TO BE HEAVY RAINFALL ASSOCIATED
WITH SHOWERS AND THUNDERSTORMS. EVEN SOME OF THE WEAKER CELLS WERE
PRODUCING HEAVY RAINFALL. ONE EXAMPLE OF THIS IS AT THE BURNS
AIRPORT...KBNO...WHICH PICKED UP ABOUT A HALF INCH OF RAIN IN ONE
HOUR. THE FLASH FLOOD WATCH WILL REMAIN IN EFFECT FOR PORTIONS OF SE
OREGON/SW IDAHO THROUGH THIS EVENING. SYSTEM WILL PUSH
EAST-NORTHEAST OF THE AREA LATE TONIGHT AND TUESDAY...BUT ANOTHER
UPPER LOW WILL DROP INTO THE REGION FROM BRITISH COLUMBIA ON
WEDNESDAY. THIS WILL MAINTAIN AT LEAST A SLIGHT CHANCE OF
SHOWERS/THUNDERSTORMS IN THE FORECAST THROUGH THE REMAINDER OF THE
SHORT TERM PERIOD...BUT NOT EXPECTING TO BE A MAJOR RAINFALL
PRODUCER. COOLING TREND WILL CONTINUE AS WELL...WITH HIGHS WELL
BELOW NORMAL ON WEDNESDAY.
.LONG TERM...TUESDAY NIGHT THROUGH MONDAY...ANOTHER LOW CENTER IS
STILL FORECAST TO DROP INTO SOUTHWEST IDAHO THURSDAY MORNING. THE
ECMWF AND GFS SOLUTIONS HAVE SHIFTED EAST WITH THE TRACK OF THE LOW.
THIS PUTS THE BEST CHANCE OF PRECIPITATION OVER SW IDAHO ZONES.
WEDNESDAY NIGHT AND THURSDAY. MEAN TROUGH SETS UP OVER THE WESTERN
U.S FOR THE WEEKEND. DIFFERENCES IN DETAILS OF TIMING AND INTENSITY
OF ENERGY DROPPING INTO THE TROUGH THROUGH THE WEEKEND. HAVE KEPT
