AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
235 AM MDT MON OCT 28 2013

.SHORT TERM...TODAY THROUGH WED NIGHT. UPPER LEVEL LOW HAS DUG
WELL SOUTH AND WILL START LIFTING TO THE NORTHEAST...BARELY
CLIPPING SOUTHERN IDAHO ON TUE...THEN LINGERING IN NORTHWEST
WYOMING ON WED. THUS EXPECT A WET AND COLDER THAN NORMAL NEAR TERM
PERIOD. STRONG SOUTHERLY WIND SHOULD DOMINATE IN THE SOUTHERN
ZONES TODAY...WHILE THE NORTHERLY WIND MSLP GRADIENT WILL SOMEWHAT
OFFSET THE STRONG SOUTHERLY WINDS ALOFT IN THE NORTHERN ZONES.
WINDS APPEAR STRONG ENOUGH IN THE SOUTH CENTRAL HIGHLANDS THAT
SUSTAINED WINDS OF 30 MPH WILL OCCUR IN THE NORTH-SOUTH ORIENTED
VALLEYS...SO HAVE ISSUED A WIND ADVISORY FOR THE AFTERNOON. MAIN
LOCATION WILL BE THE WESTERN HALF OF THAT ZONE. ELSEWHERE...IT
ALSO GETS CLOSE IN THE BURLEY AREA AND SOMEWHAT CLOSE IN THE
SOUTHERN SNAKE RIVER PLAIN. THE OTHER MAIN FORECAST PROBLEM IS
SNOWFALL AMOUNTS IN THE CENTRAL IDAHO MOUNTAINS AND THE UPPER
SNAKE HIGHLANDS. AT THIS TIME...AMOUNTS DO NOT APPEAR TO BE ENOUGH
TO GENERATE THE MINIMUM OF 5 INCHES IN 12 HOURS. 5 TO 8 INCHES IN
24 HOURS IS MORE LIKE IT. THE MAIN SNOW FALL COMES TONIGHT AS THE
COLD AIR MOVES IN AND THE AIR IN GENERAL TURNS COLDER WITH
NIGHTFALL. THE PROLONGED SOUTHERLY AIRFLOW TODAY WILL PREVENT LOW
SNOW LEVELS IN THE SOUTHERN AND EASTERN ZONES...BUT THIS WILL HAVE
TO BE MONITORED AS THE EVENT PROGRESSES...AS THE NORTHWEST AND
WESTERLY FLOW AFTER THE LOW LIFTS OUT OF THE GEM STATE WILL
CONTINUE TO PRODUCE SOME ENHANCED OROGRAPHIC PRECIPITATION AMOUNTS
FOR ALL THE EASTERN HIGHLANDS. TEMPERATURES TURN MUCH COLDER AS
THE AIRMASS MOVES INTO SOUTHERN IDAHO...TEMPERATURES ON TUE AND
WED WILL STRUGGLE INTO THE 40S FOR SNAKE RIVER PLAIN ELEVATIONS.
MESSICK

.LONG TERM...THURSDAY THROUGH NEXT MONDAY. THE GFS AND ECMWF WERE IN
FAIRLY GOOD AGREEMENT THROUGHOUT THE FORECAST PERIOD SHOWING A
MODEST IMPULSE RIDING OVER THE ERN PAC RIDGE AND DIGGING SE OVER THE
NRN ROCKIES THURSDAY RESULTING IN LIGHT PRECIPITATION ALONG THE
MONTANA/WYOMING DIVIDE THURSDAY AFTERNOON AND CONTINUING THROUGH
THURSDAY NIGHT. FRIDAY/SATURDAY...THE MODELS SHOWED DRIER CONDITIONS
SHIFTING INLAND WITH THE UPPER RIDGE AS THE NEXT PAC TROUGH
PROGRESSED TOWARD THE COAST. BY SUNDAY/MONDAY...BOTH MODELS SHOWED
THE TROUGH LIFTING INTO THE NW AND ADVANCING EAST THROUGH CANADA AND
THE NRN ROCKIES WITH ACCOMPANYING PRECIPITATION SPREADING ACROSS THE
REGION ALONG WITH COOLER TEMPERATURES. HUSTON
&&

.AVIATION...MODELS SUGGEST VFR CIGS LOWERING TO MVFR OVERNIGHT AS
THE UPPER LOW BEGINS TO SWING EAST ACROSS NRN NEVADA TODAY AND THEN
INTO THE UTAH BORDER REGION TONIGHT. ACCOMPANYING PRECIPITATION MAY
PRODUCE REDUCED VISIBILITY AT TIMES...ESPECIALLY ALONG THE FRONT
RANGE LEADING INTO THE CNTRL MOUNTAINS WHERE UPSLOPE FLOW WILL BE
MOST PRONOUNCED. HUSTON

.PIH WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY FROM NOON TODAY TO 6 PM MDT THIS EVENING IDZ022.
