AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
315 AM MST SAT FEB 4 2006

.SHORT TERM...TODAY THROUGH MONDAY. VIGOROUS UPPER TROF TO QUICKLY
MOVE ACROSS FCST/A THIS AFTN/TONIGHT. LATEST IR SAT LOOP SHOWING WAA
CLOUDS ACROSS FCST/A AHEAD OF SFC FRONT CURRENTLY ACROSS OR. COLD
FRONT TO SLIDE ACROSS REGION THIS AFTERNOON (ETA SLIGHTLY SLOWER AND
SHOWING LESS SFC GRAD). SNOFALL ACROSS MTNS SHOULD STAY WELL BELOW
WARNING CRITERIA (2-7 INCHES). SHOULD GET A SHOT OF PRECIP WITH
FRONT AND THEN A BURST OF WINDS ALONG AND BEHIND FRONT LATER THIS
AFTERNOON AND EVENING. DECIDED TO ISSUE A WIND ADV FOR ZONES 17/21
TO COVER GUSTS TO 45 MPH. DEEP OMEGA ALONG WITH 35KT 7H WINDS AND
STRONG COLD AIR ADVECTION SHOULD ENHANCE GUSTS AT SFC. WINDS SHOULD
GRADUALLY WEAKEN LATE TONIGHT. MAY SEE A SECONDARY SPOKE OF ENERGY
SLIDE SOUTH ACROSS FCST/A SUNDAY MORNING BUT BY AFTN CLEARING SKIES
FROM WEST TO EAST SHOULD OCCUR. COLD HIGH PRESSURE TO BUILD INTO
AREA FOR SUNDAY NIGHT.

WINTHER

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY NIGHT.  STRONG RIDGE ON
5-WAVE 500MB PATTERN ONLY BREAKS DOWN SLIGHTLY AT VERY END OF THIS
PERIOD.  EVEN THEN...IT BREAKS DOWN ONLY SLIGHTLY ON ITS EASTERN
EDGE AS SHORTWAVES MOVE THROUGH THE BACKSIDE OF THE UPPER LEVEL
PATTERN.  THE STRONG AMPLITUDE TOWARDS THE END...COUPLED WITH THE
UPPER LEVEL RIDGE AXIS STAYING WEST OF THE FORECAST AREA...MEANS
THAT LOW TEMPERATURES SHOULD BE COLD.  DAYTIME SUNSHINE SHOULD MEAN
STRONG WARMING DURING THE DAY.  THE FLY IN THE OINTMENT FOR THIS
HIGH PRESSURE DOMINATION IS WHAT WILL HAPPEN IN THE BOUNDARY LAYER
WITH A STRENGTHENING INVERSION.  THAT COULD BRING ON FOG PROBLEMS.
HOWEVER THE BEST PART OF FOG SEASON IS JUST ABOUT OVER
CLIMATICALLY-SPEAKING...ALTHOUGH NOT OUT OF THE QUESTION.  WILL
LEAVE FOG MONSTER OUT OF FORECAST FOR NOW. MESSICK

&&

.AVIATION...PLENTY OF TURBULENCE ALOFT SHOULD KEEP GOOD CIG/VSBY
WITH ALL THE MIXING THIS MORNING.  SWIFT-MOVING FRONT WILL PUSH
THROUGH THIS COMING EVENING...BRING SOME PRECIP AND AT LEAST
MARGINAL VFR...WITH IFR LIKELY AT KIDA AND KSUN...TO ALL AIRPORTS.
WINDS WILL BE THE MAIN FEATURE HOWEVER.  SHOULD BE AS MUCH AS 30KT
SUSTAINED THOUGH FOR MOST AIRPORTS STRAIGHT DOWN THE RUNWAY.  FROPA
AT KPIH/KIDA BETWEEN 05/02Z AND 05/03Z...EARLIER AT
KBYI/KSUN..04/23Z AND 05/00Z.  MESSICK

.PIH WATCHES/WARNINGS/ADVISORIES...WIND ADVISORY THIS AFTERNOON AND
