Area forecast discussion, Jun 30, 1:07 PM MST, 4 hours 48 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 207 PM MDT WED JUN 30 2010 .SHORT TERM...SITTING ON THE EDGE WITH THE FORECAST FOR THIS EVENING. THE 12Z NAM BRINGS A 700MB TROUGH INTO THIS AREA WITH A SURFACE LOW PRESSURE WAVE DEVELOPING IN NORTHEAST NEVADA AND TRACKING TOWARDS IDAHO FALLS AND DRIGGS. BEST CHANCE FOR PRECIPITATION SHOULD BE 00-06Z. ISOLATED LIGHTNING STRIKES ALREADY THIS AFTERNOON NEAR CHALLIS AND AFTERNOON CLOUDS DEVELOPING TO THE SOUTHWEST. THE BIG QUESTION IS WAS THE DRY AIR MOVING IN FROM THE GREAT BASIN TOO DRY? SURFACE ANALYSIS SHOWS SOME EVIDENCE OF A SURFACE WAVE DEVELOPING NEAR WENDOVER. SATELLITE DERIVED LIS FROM BURLEY TO ISLAND PARK ARE DEFINITELY DESTABILIZING AND THE SURFACE HEATING UP WITH LACK OF CLOUD COVER. THE RUC SEEMS TO HAVE TRENDED A LITTLE BIT DRIER BUT STILL DEVELOPS CONVECTION IN THE SNAKE PLAIN THIS EVENING. WILL KNOW IN A FEW HOURS. MESO SCALE DISCUSSION JUST ISSUED FROM SPC SUPPORTS CONTINUED VIGILANCE THE NEXT FEW HOURS. THE 12Z NAM SUPPORTED STRONG DOWN DRAFT WINDS NEAR SEVERE 50-60 MPH RANGE. THE NAM STILL FAVORS CONVECTION IN THE SNAKE PLAIN EVEN THURSDAY MORNING AND AFTERNOON. NO SIGNIFICANT CHANGE TO THE FORECAST HERE. THE GFS IS AMPLIFYING THE TROUGH MOVING INLAND FRIDAY NIGHT AND SATURDAY WITH GUIDANCE SUPPORTING HIGH TEMPERATURES IN THE LOWER 70S FOR THE SNAKE PLAIN...ALMOST 15 DEGREES BELOW NORMAL. THE GFS IS A LITTLE MORE AMPLIFIED THAN THE OTHER MODELS AND COULD BE AN OUTLIER. OTHERWISE...A MORE ZONAL AND DRIER PATTERN SUNDAY AND MONDAY MAYBE AND ISOLATED AFTERNOON SHOWER IN THE CENTRAL MOUNTAINS. RS && .AVIATION...VFR CONDITIONS WILL RULE THROUGH THE NEXT 24 HOURS. ISOLATED THUNDERSTORMS THIS AFTERNOON WILL BECOME SCATTERED ACROSS THE THE AREA THIS EVENING. NUMEROUS THUNDERSTORMS ARE POSSIBLE IN THE CENTRAL MOUNTAINS...INCLUDING THE KSUN AREA. SOME STORMS MAY BE STRONG TO SEVERE AND WILL CONTAIN WIND GUSTS TO 60 MPH IN ADDITION TO FREQUENT LIGHTNING. ACTIVITY WEAKENS AND DIMINISHES AFTER MIDNIGHT. ISOLATED MOUNTAIN THUNDERSTORMS ARE POSSIBLE FOR THURSDAY AFTERNOON. && .FIRE WEATHER...ISOLATED THUNDERSTORMS ARE EXPECTED TO BECOME SCATTERED THROUGH THIS EVENING ACROSS THE FORECAST AREA WITH NUMEROUS THUNDERSTORMS DEVELOPING IN THE CENTRAL MOUNTAINS. SOME OF THESE STORMS MAY CONTAIN VERY STRONG GUSTS AND FREQUENT LIGHTNING. ACTIVITY WEAKENS AND DIMINISHES AFTER MIDNIGHT. A TROUGH MOVES THROUGH THE AREA THURSDAY INTO THE WEEKEND AND WILL BRING COOLER TEMPERATURES AND ISOLATED AFTERNOON AND EVENING MOUNTAIN THUNDERSTORMS. && .PIH WATCHES/WARNINGS/ADVISORIES...NONE. &&
