NWS Pocatello, ID wrote its last area forecast discussion before the first event at Aug 14, 12:50 PM MST, 3 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 150 PM MDT THU AUG 14 2014 .DISCUSSION...THE PERSISTENT UPPER LOW WAS LOCATED OVER THE COLUMBIA GORGE THIS AFTN...AND EXPECTED TO FILL AND MOVE TO NC MT ON SATURDAY. MOST OF THE MONSOON MOISTURE HAS MOVED OFF TO THE NORTH AND EAST...BUT ENOUGH MOISTURE LINGERS TO FUEL SHOWERS/TSTMS OVER THE FCST AREA. GREATEST COVERAGE WILL BE IN THE EAST AND NORTH PARTS OF THE FCST AREA. SOME TSTMS MAY PRODUCE GUSTY WINDS AND SMALL HAIL...ESPECIALLY LATE THIS AFTN. ACTIVITY WILL DIMINISH THIS EVENING OVER THE WESTERN PARTS AND THE SNAKE RIVER PLAIN... BUT CONTINUE NEAR THE WY AND MT BORDERS. ON FRIDAY...DRIER AIR BECOMES MORE DOMINANT. THIS WILL LIMIT ACTIVITY TO ONLY ISOLD TSTMS IN THE CENTRAL MTNS AND EASTERN HIGHLANDS. BY SATURDAY...THE UPPER LOW MOVES FAR ENOUGH AWAY TO LIMIT ACTIVITY TO ALONG THE DIVIDE. WEAK UPPER RIDGING SETS UP FOR THE REST OF THE WEEKEND AND PERSISTS THRU TUE. THIS WILL RESULT IN DRY CONDITIONS AND WARMER TEMPS THRU TUE. BY WED...THE PATTERN SHOWS SIGNS OF CHANGE. THE NORTHERN STREAM BEGINS TO SAG SOUTHWARD INTO THE PAC NW...AND SUGGEST COOLER TEMPS FOR WED AND THU. ALSO...THE POSSIBILITY OF SHOWERS NEAR THE DIVIDE. HEDGES && .AVIATION...UPPER LEVEL LOW IN THE PACIFIC NORTHWEST CONTINUES TO BRING MOIST UNSTABLE AIR INTO SOUTHERN/CENTRAL IDAHO. NOT MUCH IN THE WAY OF WIND UNLESS THUNDERSTORM OUTFLOW REACHES AIRDROME. GFS HAD THE BETTER INSTABILITY FORECAST...AND KSUN SHOULD BE OUT OF ANY SERIOUS THUNDERSTORM ACTIVITY. BUT KIDA AND KPIH HAVE NEGATIVE LIFTED INDICES AND CAPE GREATER THAN 300J/KG THROUGH NEARLY 15/06Z. SO HAVE EXTENDED VCTS FORECAST FOR THOSE TWO AIRPORTS AND INTRODUCED ONE UNTIL 15/00Z AT KBYI...WHEN LIFTED INDEX AND CAPE ARE NEGATIVE/ABOVE 300J/KG. SPC IS CONSIDERING A SEVERE THUNDERSTORM WATCH WITH GOOD INVERTED-V SOUNDINGS...SO HAVE PUT IN TEMPO GROUP OF TSRA ACTIVITY FOR MID- TO LATE AFTERNOON PERIOD AT THESE TWO LOCATIONS. BOTH HAVE MORE THAN 40 PERCENT CHANCE OF THUNDERSTORMS IN MOS GUIDANCE...GOOD UPPER LEVEL DIFFLUENCE...AND STABILITY PARAMETERS ALL POINT TO INTENSE AND WIDESPREAD TSRA ACTIVITY. CLEARING SHOULD TAKE PLACE TONIGHT AS THIS UPPER LEVEL LOW FINALLY GETS IN PHASE WITH A MORE NORTHERN SHORTWAVE WHICH ACTS AS A KICKER TO THE PACIFIC NORTHWEST LOW. THERE IS ALSO A POTENTIAL ROUND OF SHRA LATE TONIGHT. ONLY IMPACT TO CIG OR VSBY WOULD BE REDUCED VSBY IN TSRA. WINDS OUTSIDE OF TSRA CONTINUE LIGHT. MESSICK && .FIRE WEATHER...CLOSED UPPER LEVEL LOW LINGERING OVER THE PACIFIC NORTHWEST FOR ANOTHER 24 HOURS OR SO...THUS EXPECT MORE THUNDERSTORM ACTIVITY WITH LESS INTENSE SHOWERS. STILL...A GOOD PORTION OF THE THUNDERSTORMS WILL BRING WETTING RAINS. THE LOW...AFTER LINGERING FOR NEARLY 9 DAYS...WILL BEGIN TO MOVE OUT AS IT GETS ABSORBED BY A STRONG TROUGH MOVING THROUGH NORTHERN CANADA. AS IT CLEARS OUT FRI...DRYING DEVELOPS...ALBEIT SLOW. THE UPPER LEVEL HAS A STRONGER WESTERLY FLOW THAT WILL MEAN STRONGER WINDS THAN WE HAVE BEEN HAVING LATELY WITH WED AND THU LOOKING MUCH STRONGER FOR WIND. SLOW DRYING OF HUMIDITY AS TEMPERATURES WILL NOT SEE MUCH OF A WARM UP DESPITE MAINLY CLEAR SKIES. MESSICK && .PIH WATCHES/WARNINGS/ADVISORIES... NONE. &&
