SOUTHEAST IDAHO AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO/IDAHO FALLS ID 340 PM MDT THU JUL 17 2003 SATELLITE SHOWS MOISTURE ROTATING AROUND FOUR CORNERS HIGH AND THROUGH SOUTHEAST IDAHO. SLIGHT DEFORMATION AREA ARCING THROUGH THE CENTRAL MOUNTAINS THIS AFTERNOON WHERE ISOLATED DRY THUNDERSTORM CAN NOT BE RULED OUT THIS EVENING. CHALLIS REPORTED WIND GUST TO 28KTS THAT MIGHT BE THE RESULT OF DRY MICRO BURST...PREVIOUS HOUR WINDS WERE 5 KTS. LITTLE INDICATION ON RADAR AND NO LIGHTNING REPORT AS YET. VISIBLE IMAGERY SHOWS OTHER CONVECTION OVER CASSIA COUNTY ANGLED OFF TO NORTHERN BANNOCK COUNTY AND SWAN VALLEY. AGAIN NO LIGHTNING INDICATED AND NOT MUCH ON RADAR. JUST ENOUGH FOR SLIGHT CHANCE WORDING THIS EVENING. FRIDAY SHOWS LITTLE CHANGE. H7 TEMPERATURES AND 1000-500MB THICKNESS SHOW LITTLE CHANGE. GFS AND MESOETA ARC A FINGER OF MOISTURE THROUGH CENTRAL MOUNTAINS AND PERHAPS SLIGHTLY DRIER AIR THROUGH THE UPPER SNAKE RIVER VALLEY WHILE THE HEAVIER MOISTURE ROTATES INTO WYOMING. DIFFICULT TO TELL FROM WATER VAPOR IF THIS WILL HAPPEN EXACTLY THAT WAY. THERE IS A FINGER OF DRY AIR IN WATER VAPOR RIGHT OVER FOUR CORNERS THAT LOOKS LIKE IT COULD BE DRAWN THIS WAY. MODELS EVEN AT 12 HOURS DO NOT SHOW STRONG CONTINUNITY WITH LITTLE SUBTLE FEATURES. CASE IN POINT IS THUNDERSTORMS THAT SHOULD HAVE BEEN IN POCATELLO AREA THIS AFTERNOON ARE NOW MORE IN UTAH AND SOUTHWEST WYOMING. HAVE GONE WITH MORE PERSISTENCE IN FORECAST...BOTH WITH POPS AND TEMPERATURES. BETTER CHANCE FOR THUNDERSTORMS SATURDAY SINCE MODELS LAST COUPLE RUNS ROTATE DISTURBANCE AROUND HIGH UP THROUGH CENTRAL MOUNTAINS. HAVE ADJUSTED POPS UP SLIGHTLY FOR THIS. GENERAL TREND ESPECIALLY IN GFS IS TO SHIFT CENTER OF HIGH FROM FOUR CORNERS INTO CENTRAL OR NORTHERN NEVADA THROUGH MONDAY AND TUESDAY. GFS TRIES TO SHIFT FLOW OVER FORECAST AREA TO NORTHWEST AND BRING DRIER AIR IN ESPECIALLY ON TUESDAY. GFS ALSO MOVES MOISTURE FROM CLAUDETTE FROM SOUTHERN ARIZONA TO A POINT JUST OFF THE CENTRAL CALIFORNIA COAST AND HOLD IT THERE ROUGHLY IN A COL AREA BY MONDAY. NOT SURE IF THE MODEL KNOWS WHAT TO DO WITH IT AFTER THAT. PREVIOUS MODEL RUN WRAPPED MOISTURE BACK TOWARDS IDAHO MORE. WILL NOT MAKE ANY WHOLESALE CHANGES TO FORECAST AT THIS TIME. SURVICK KSFX...OPERATIONAL...VCP 21. .PIH...NONE.
