AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
222 PM MDT MON APR 4 2011

.SHORT TERM...SURFACE LOW AND COLD FRONT STILL ON TRACK TO MOVE
INTO THE WESTERN EDGE OF THE FORECAST AREA LATE TONIGHT AND SPREAD
LOW ELEVATION RAIN AND MOUNTAIN RAIN AND SNOW INTO CENTRAL AND
EASTERN IDAHO. JET ALOFT WILL PUT A RIGHT ENTRANCE TO A JET STREAK
DIRECTLY OVER THE FORECAST AREA AND ENHANCE THE PRECIPITATION. SO
WILL ISSUE SNOW ADVISORY FOR VERY HIGH ELEVATIONS...ZONE 18 ABOVE
6000 FT...ZONE 31 ABOVE 7000 FEET...AND THE EAST SIDE MOUNTAINS
ZONES 19 23 AND 25 ABOVE 7000 FEET. MORE IMPACT WILL COME FROM THE
WINDS. THE STRONG 140KT JET AND STRONG 500MB WIND FLOW...ALONG
WITH STRONG COLD AIR ADVECTION WITH THE FRONT...SHOULD PRODUCE A
VERY STRONG SURFACE WIND. 700MB AIRFLOW IS NOT AS STRONG...NEITHER
IS THE INSTABILITY...BUT LOCAL WIND STUDY INDICATED NEAR HIGH WIND
WARNING FOR 05/18Z THROUGH 06/00Z. MUST BE MONITORED TO SEE IF THE
ADVISORY NEEDS TO GO TO WARNING...OR IF EASTERN MAGIC VALLEY
SHOULD BE ADDED. CURRENTLY...A SURFACE LOW EXPECTED IN
NORTHWESTERN UTAH FLATTENS THE GRADIENT IN EXTREME SOUTH CENTRAL
IDAHO IS ABOUT THE ONLY THING THAT IS KEEPING WIND LOWER IN THAT
ZONE COMPARED TO THE TWO SNAKE RIVER PLAIN ZONES. CONDITIONS CALM
DOWN TUE NIGHT WITH SNOW ENDING IN THE EASTERN BORDER ZONES IN THE
LATE NIGHT HOURS/WED MORNING. WED MORNING IS ABOUT THE ONLY
BREATHER AS YET ANOTHER SHORTWAVE MOVES IN FOR WED NIGHT. THIS IS
A MUCH COLDER SHORTWAVE THAT COULD PRODUCE SOME LIGHT SNOW AS LOW
AS THE SNAKE RIVER PLAIN.  MESSICK

.LONG TERM...THURSDAY THROUGH MONDAY. THE ACTIVE PATTERN LOOKS TO
CONTINUE THROUGH THE TIMEFRAME. MODELS CONTINUE TO SHOW A COLD LOW
MOVING INTO THE AREA FOR THE THURSDAY TIMEFRAME. SOME
AREAS...ESPECIALLY THE VALLEYS COULD START WITH A BIT OF SUNSHINE
ALTHOUGH WITH STEEP LAPSE RATES AND NEGATIVE LIFTED INDICIES
SHOWERS WILL POP UP AROUND THE REGION. THERE COULD EVEN BE SOME
THUNDER AND POSSIBLY SOME GRAUPEL BUT DIDNT INCLUDE IN THE
FORECAST AT THIS TIME. THERE WERE FEW CHANGES PAST THURSDAY WITH
THE LOW MOVING TO THE EAST AND SOME RAIN AND SNOW SHOWERS
CONTINUING...ESPECIALLY ACROSS THE FAVORED UPSLOPE AREAS OF THE
CENTRAL MOUNTAINS AND THE EASTERN HIGHLANDS. THINGS BEGIN TO DRY
OUT LATER SATURDAY AS SOME RIDGING BUILDS ACROSS THE REGION.
SUNDAY LOOKS BE THE DRIEST DAY OF THE PERIOD AT THIS POINT. MODELS
REALLY DIVERGE FOR MONDAY WITH THE GFS BRINGING LOOKING MORE
PROGRESSIVE IN BRINGING IN ANOTHER SYSTEM WHILE THE EUROPEAN MODEL
BUILDS THE RIDGE AND KEEPS IT DRY. AT THIS TIME WE WENT CLOSE TO
CLIMO. TEMPERATURES WILL REMAIN BELOW NORMAL THROUGH THE PERIOD
WITH SOME MODERATION DURING THE WEEKEND. HATTINGS

&&

.AVIATION...CEILINGS WILL CONTINUE TO LOWER AND SOUTHWEST TO WEST
WIND WILL REMAIN UP AT THE LOWER ELEVATIONS AIRDROMES AS A COLD
FRONT APPROACHES FOR LATE TONIGHT.  THE HIGHER ELEVATION KSUN SHOULD
HAVE PROBLEMS LATE TONIGHT AND TUE MORNING DUE TO SNOW REDUCING
VISIBILITY AND CEILING.  HOWEVER...THIS IS A LOW CONFIDENCE FORECAST
AS TEMPERATURES WILL BE VERY CLOSE TO THE FREEZING MARK AND COULD
STAY ABOVE.  ELSEWHERE...RAIN WILL BRING THE CEILING LOW BUT SHOULD
STAY GOOD VFR. VERY WINDY FOR MUCH OF TUE BUT SHOULD BE RIGHT DOWN
THE RUNWAY MOST LOCATIONS.  KSUN SHOULD BE THE LEAST WINDY WITH
NORTHWEST WIND WHILE THE OTHER AIRPORTS STAY WESTERLY.  SHOULD BE
EVEN STRONGER IN THE AFTERNOON.  MESSICK
