NWS Pocatello, ID wrote its last area forecast discussion before the first event at May 9, 12:55 PM MST, 1 hour 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 155 PM MDT FRI MAY 9 2014 .SHORT TERM...TONIGHT THROUGH MONDAY. THE LATEST SATELLITE IMAGERY WAS SHOWING A BROAD UPPER TROUGH ACROSS THE NW STATES WITH AN INITIAL EJECTING WAVE SHEARING EAST INTO WYOMING AND THE MAIN UPPER LOW EXTENDING INTO THE WASHINGTON COAST. THE MODELS SHOW A DECREASING PRECIPITATION TREND THIS EVENING AS THE INITIAL WAVE EXITS TO THE EAST AND THE LOSS OF DAYTIME HEATING REMOVE BOTH DYNAMIC AND THERMO-DYNAMIC SUPPORT FOR CONVECTION. WITH THE LOSS OF CONVECTION...WE SHOULD ALSO SEE A DECOUPLING FROM THE FLOW ALOFT AND DECREASING WINDS. AFTER MIDNIGHT...THE SECOND ROUND OF PRECIPITATION IS EXPECTED TO BEGIN SPREADING ACROSS THE CNTRL AND SRN MOUNTAINS AS THE MAIN UPPER LOW SHIFTS INLAND. THE ADDITION OF DAYTIME HEATING SATURDAY AFTERNOON COUPLED WITH THE SLOW PROGRESSION OF THE UPPER LOW WILL HELP TO ENHANCE THE CONVECTIVE PRECIPITATION POTENTIAL THROUGHOUT THE DAY WITH NUMEROUS SHOWERS IN THE MOUNTAINS AND A GOOD CHANCE OF SHOWERS IN THE VALLEYS. DECENT CONVECTIVE ACTION MAY ARTIFICIALLY LOWER SNOW LEVELS TO VALLEY FLOORS DURING THE DAY AS WELL WITH UPWARDS OF 3 INCHES OF SNOWFALL ACROSS THE HIGHER MOUNTAIN PASSES BY SATURDAY AFTERNOON. THE UPPER LOW SHIFTS SOUTHEAST OF THE REGION SATURDAY NIGHT/SUNDAY WITH LINGERING MOISTURE AND INSTABILITY SUPPORTING ISOLATED MAINLY MOUNTAIN SHOWER ACTIVITY SUNDAY AFTERNOON. BY MONDAY FAIRLY DRY CONDITIONS ARE ANTICIPATED ACROSS THE REGION AS A RIDGE OF HIGH PRESSURE BUILDS ALONG THE COAST. WITH THE GRADUAL CLEARING SUNDAY MORNING INTO MONDAY MORNING WE ARE ANTICIPATING THE NEED FOR A FROST ADVISORY SUNDAY MORNING AND A HARD FREEZE WARNING FOR A PORTION OF THE SNAKE RIVER PLAIN MONDAY MORNING. MORE ON THAT AS THE EVENT DRAWS NEAR. HUSTON .LONG TERM...MONDAY NIGHT THROUGH FRIDAY. OVERALL PATTERN IS FOR UPPER RIDGE TO STILL BUILD TO THE WEST OF IDAHO WITH NORTHWEST FLOW ALOFT THROUGH THE PERIOD. SHOULD BE A DRY PERIOD WITH LITTLE IF ANY PRECIPITATION AND ONLY HAVE SLIGHT CHANCE OCCASIONALLY IN THE EASTERN HIGHLANDS. EXPECT SLOWLY MODERATING TEMPERATURES THROUGH THE PERIOD WITH WELL ABOVE NORMAL TEMPERATURES EXPECTED BY WEDNESDAY AND CONTINUING INTO FRIDAY. GK && .AVIATION...EXPECT THE VERY WINDY CONDITIONS TO PERSIST THROUGH LATE AFTERNOON AT IDA AND PIH WITH 25 TO 35 KNOT SUSTAINED WINDS EXPECTED. SHOULD DIE DOWN BY SUNSET. SHOWER ACTIVITY HAS THINNED OUT A BIT AND HAVE VICINITY AT BYI...PIH AND IDA THROUGH THE AFTERNOON AS WELL. FOR THE MOST PART EXPECT VFR CONDITIONS OTHER THAN UNDER A SHOWER WHERE THEY OCCUR. ANOTHER UPPER LOW PUSHES EAST SATURDAY AND SURFACE GRADIENT TIGHTENS AS WELL AND EXPECT WINDS TO PICK UP AGAIN SATURDAY MORNING TO THE 15 TO 25 KNOT SUSTAINED LEVEL AT BYI...PIH AND IDA ONCE AGAIN. LIKELY NOT QUITE AS STRONG AS TODAY HOWEVER. WILL LIKELY HAVE SHOWERS UNDER THIS UPPER TROF ONCE AGAIN BUT NOT WIDESPREAD OR CONTINUAL AT ANY SITE. GK && .PIH WATCHES/WARNINGS/ADVISORIES... WIND ADVISORY CONTINUES THROUGH 9 PM MDT THIS EVENING IDZ017-020-021. &&
