AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 315 AM MDT SUN JUL 28 2013 .SHORT TERM...TODAY THROUGH TUE NIGHT. HIGH PRESSURE CENTERED OVER THE SOUTHERN TIER OF STATES WILL STRENGTHEN DURING THIS TIME. THIS IS MOVING THE WEAK LOW PRESSURE TRACK FARTHER NORTH. THE THREAT APPEARS LESS THAN YESTERDAY...BOTH IN THE GFS AND IN THE HRRR TRENDS. THUS HAVE LOWERED THE THUNDERSTORM THREAT TO JUST ISOLATED AND SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE THE MAIN WEATHER PHENOMENA AFFECTING THE FORECAST AREA. WIND WILL CONTINUE FAIRLY WEAK UNDER HIGH PRESSURE...AT LEAST OUTSIDE OF THUNDERSTORMS. THUS DO NOT SEE ANY KIND OF LAKE WIND ADVISORY FOR THE THE NEAR TERM FORECAST. DIMINISHING CLOUD COVER DAY TO DAY WILL ALLOW TEMPERATURES TO WARM BACK UP. MESSICK .LONG TERM...WED THROUGH SAT NIGHT. SHOWERS AND THUNDERSTORMS...MAINLY IN THE HIGHER ELEVATIONS AND ESPECIALLY IN THE SOUTHEAST CORNER OF THE FORECAST AREA...WILL CONTINUE TO BE THE MAIN THREAT. A WEAK TROUGH MOVING THROUGH THE MEAN RIDGE ON THU NIGHT/FRI WILL INCREASE THE INSTABILITY AND SO A SLIGHTLY HIGHER THREAT OF SHOWERS AND THUNDERSTORMS FOR THAT DAY...THEN LOWERING CHANCE FOR THE END OF THE PERIOD. ECMWF THEN TURNS WETTER FOR THE WEEKEND WHILE GFS CONTINUES STATUS QUO WITH LITTLE CHANGE TO THE UPPER LEVEL PATTERN. ECMWF HAD SOME WIDE SWINGS IN THE LAST TWO RUNS...THE 27/12Z HAD 594DM HEIGHTS FOR 500MB OVER THE FORECAST AREA...WHILE THE LATEST 28/00Z HAS THE STRONGEST TROUGH DURING THIS PERIOD MOVING IN. HAVE SPLIT THE DIFFERENCE AND OFFER A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS TO THE EASTERN PORTION OF THE FORECAST AREA WHERE THE TIMING OF THE SHORTWAVE PUTS THE BEST CHANCE FOR THUNDERSTORMS FOR THE NEW DAY. BUT THIS WEAK WAVE APPARENTLY DOES LITTLE TO THE WIND AND SO ITS EFFECTS ARE MINIMAL. MESSICK && .AVIATION...ANOTHER WEAK FRONT WILL PASS THROUGH THE REGION TODAY. ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS THE AREA. OTHERWISE VFR CONDITIONS REMAIN LIKELY WITH A FEW GUSTS TO 20 KTS POSSIBLE THIS AFTERNOON. VALLE && .FIRE WEATHER...A WEAK FRONT WILL PASS THROUGH THE REGION TODAY. ISOLATED THUNDERSTORMS AND WIND GUSTS TO 45 MPH ARE POSSIBLE NEAR THUNDERSTORMS. OTHERWISE THE COMBINATION OF WIND GUSTS AND HUMIDITY WILL REMAIN BELOW CRITICAL THRESHOLDS. ISOLATED THUNDERSTORMS WILL PERSIST FOR MUCH OF THE WEEK AS MOISTURE STREAMS INTO THE AREA. VALLE && .PIH WATCHES/WARNINGS/ADVISORIES... NONE. &&
