330 PM MDT SUN APR 8 2007

.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT. UPPER LOW SITUATED NEAR
SLC WILL MOVE SLOWLY EAST. WRAP-AROUND MOISTURE/INSTABILITY
COULD RESULT IN SHOWERS WITH POSSIBLY AN ISOLATED THUNDERSTORM ACROSS
SE ZONES THRU 06Z.  SHORT WAVE RIDGE BUILDS INTO AREA LATE TONIGHT.
THIS WILL BE SHORT LIVED...GFS FORECASTING A COLD FRONT TO TRACK
ACROSS AREA BY MID-DAY MONDAY. FRONT WILL PRODUCE MTN SHOWERS AND
STRONG GUSTY WINDS ACROSS THE SNAKE VALLEY. IN FACT...WIND SCHEME
SUGGESTS ADVISORY LEVEL WINDS FROM BYI TO IDA...25 TO 35 MPH WITH

.LONG TERM...LOW CONFIDENCE FORECAST FOR THIS ENTIRE PERIOD.  RUN TO
RUN CONSISTENCY HAS NOT BEEN PRESENT FOR SOME MODERATE TO STRONG
WAVES FOR THIS PERIOD.  AND THE REASON WHY IS FAIRLY SIMPLE.  500MB
5-WAVE PATTERN INDICATES NEAR ZONAL FLOW FOR WESTERN NORTH AMERICA
OF A MODERATE TO STRONG INTENSITY.  SO TIMING OF EMBEDDED SHORT
WAVES CAN CHANGE WITH THE SLIGHTEST CHANGE IN PERTURBATION.  BY SAT
NIGHT...ECMWF AND GFS/LR ARE 180 DEGREES OUT OF PHASE WITH GFS
SHOWING UPPER LEVEL RIDGE...ECMWF SHOWING UPPER LEVEL TROUGH.
PREFER NOT TO WHIP-SAW AROUND...BUT HAVE INCREASED POPS IN SOME
PERIODS TO BRING IN AT LEAST A MENTION OF PRECIP THREAT FOR THE
DAY.  TEMPERATURES HAVE TRENDED COLDER BUT WARMEST DAY STILL
DEPENDENT ON SHORTWAVE TIMING.  MESSICK

&&

.AVIATION...SHORTWAVE ALONG ID-UT BORDER COULD WREAK SOME HAVOC IN
THAT AREA THIS LATE AFTERNOON AND EVENING...AND STRATUS CONTINUES TO
BE PROBLEMATIC FOR KSUN.  GUIDANCE IN GENERAL HAS BEEN NO HELP WITH
EVEN WINDS BEING INCORRECT.  ONLY A GENERAL CLEARING TREND FOR THE
REMAINDER OF TDA APPEARS CORRECT.  HOWEVER...FOR MON
AFTERNOON...EVEN GUIDANCE IS IN AGREEMENT THAT A SIGNIFICANT WIND
EVENT IS APPROACHING.  THIS WILL AFFECT VALLEY AIRPORTS KBYI KPIH
AND KIDA.  EXPECTING ONLY LIGHT PRECIPITATION AND CEILING TO STAY
VFR CONDITIONS.  MESSICK
