AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
250 AM MDT SAT SEP 12 2015

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT. A RIDGE OF HIGH PRESSURE
REMAINED POSITIONED OVER THE WRN STATES EARLY THIS MORNING AS THE
PACIFIC STORM TRACK PUNCHED EAST THROUGH NRN CANADA. FURTHER SOUTH
AND WEST...SUB-TROPICAL MOISTURE ASSOCIATED WITH SEVERAL WEAK
DISTURBANCES WAS NOTED ROTATING NORTH AROUND THE WRN PERIPHERY OF
THE HIGH. MODEL SOLUTIONS SHOW THIS MOISTURE ROTATING INTO SRN IDAHO
SUNDAY MORNING HELPING TO SUPPORT/FUEL ISOLATED AFTERNOON/EVENING
CONVECTION OVER THE CNTRL MOUNTAINS AND SOUTH-CNTRL HIGHLANDS. BOTH
THE GFS AND NAM ARE A BIT MORE OPTIMISTIC REGARDING COVERAGE AND
CHANCES THIS MODEL CYCLE AND THUS HAVE BUMPED PRECIP CHANCES UP SOME
DURING THIS TIME FRAME. BY MONDAY...A PAC TROUGH BEGINS TO TAKE
SHAPE OFF THE NW COAST WITH THE UPPER FLOW BECOMING MORE
SOUTHWESTERLY AND MOIST. PRECIPITATION CHANCES INCREASE FAIRLY
RAPIDLY MONDAY AFTERNOON INTO TUESDAY AS SEVERAL DISTURBANCES EJECT
NE ACROSS THE REGION AMPLIFYING PRECIPITATION PRODUCTION ACROSS THE
REGION IN THE MOIST SW FLOW. COOLER TEMPERATURES (20 DEG) ARE ALSO
EXPECTED TO FILTER INTO THE REGION WITH EACH PASSING WAVE. NUMERICAL
SOLUTIONS HAVE NOT BEEN ALTOGETHER CONSISTENT WITH THE
EVOLUTION/DETAILS OF THE TROUGH BUT THE POTENTIAL IS FAIRLY HIGH SO
HAVE BOOSTED PRECIP CHANCES HERE AS WELL.

.LONG TERM...WEDNESDAY THROUGH NEXT SATURDAY. A THIRD DISTURBANCE
EJECTS NE THROUGH THE REGION WEDNESDAY AS REINFORCING ENERGY DIGS
INTO THE PAC NW COAST. THIS ENERGY EJECTS EAST THROUGH THE REGION
THURSDAY WITH ANOTHER ROUND OF PRECIPITATION EXPECTED. PREVIOUS
MODEL RUNS WERE SHOWING A BREAK IN THE ACTION WEDNESDAY WHEREAS THIS
CYCLE IS NOT AS CLEAN. FRIDAY AND BEYOND...THE MAIN STORM TRACK
LIFTS JUST NORTH OF THE REGION WITH LITTLE OR NO PRECIP ANTICIPATED
AT THIS TIME AND SLIGHTLY MODERATING TEMPS THROUGH THE PERIOD.
HUSTON
&&

.AVIATION...VFR CONDITIONS TO PERSIST THROUGH THE TAF PERIOD AS HIGH
PRESSURE REMAINS IN PLACE. SOUTHWESTERLY AFTERNOON WINDS EXPECTED
ACROSS THE SNAKE PLAIN...WITH SOME GUSTS AROUND 15 KTS POSSIBLE AT
PIH AND IDA. AD
&&

.FIRE WEATHER...HIGH PRESSURE IN PLACE OVER THE GREAT BASIN WILL
ALLOW A FOR A CONTINUATION OF THE UNSEASONABLY WARM AND DRY WEATHER
TODAY. WIDESPREAD MINIMUM RELATIVE HUMIDITY VALUES IN THE 10 TO 15
PERCENT RANGE ANTICIPATED. EXPECT WINDS TO NUDGE UP SLIGHTLY OVER
WHAT WAS EXPERIENCED ON FRIDAY...BUT SHOULD STILL REMAIN UNDER 20
MPH ACROSS SE ID. SOME INCREASE IN MOISTURE EXPECTED SUNDAY AS THE
HIGH PRESSURE RIDGE BEGINS TO WEAKEN. ISOLATED SHOWERS AND
THUNDERSTORMS ANTICIPATED...PARTICULARLY ACROSS THE SOUTHERN
HIGHLANDS...CENTRAL MOUNTAINS...AND UPPER SNAKE HIGHLANDS. MIN RH
VALUES EXPECTED TO GENERALLY BE IN THE 15 TO 20 PERCENT
RANGE...SLIGHTLY HIGHER THAN SATURDAY. MAIN STORY SUNDAY WILL BE AN
INCREASE IN WINDS WITH WIDESPREAD GUSTS IN THE 20 TO 30 MPH
RANGE...WHICH COULD CERTAINLY EXCITE ANY EXISTING FIRE ACTIVITY.
WILL HOLD OFF ON ANY FIRE WEATHER HEADLINES ATTM...HOWEVER FIRE
ACTIVITY MAY INCREASE DUE TO THE INCREASE IN WINDS AND CONTINUED LOW
RH. MOISTURE WILL INCREASE MONDAY AND TUESDAY AHEAD OF A STRONG
PACIFIC SYSTEM. EXPECT SHOWER AND THUNDERSTORM ACTIVITY TO INCREASE
THROUGHOUT THE DAY MONDAY...WITH WIDESPREAD SHOWERS AND ISOLATED TO
POTENTIALLY SCATTERED THUNDERSTORMS BY LATE AFTERNOON AND EVENING.
THIS ACTIVITY SHOULD CONTINUE INTO TUESDAY...WITH A DRAMATIC
DECREASE IN TEMPERATURES BEHIND A STRONG COLD FRONT TUESDAY.
TEMPERATURES SHOULD FALL AROUND 20 DEGREES COMPARED TO MONDAY. THIS
FRONT WILL BRING AN INCREASE IN WINDS...WITH SOME GUSTS TO 35 MPH
POSSIBLE TUESDAY AFTERNOON AND EVENING. SOME DRYING EXPECTED
WEDNESDAY BEFORE ANOTHER TROUGH SWEEPS THROUGH THE REGION BY LATE
WEEK...AGAIN INCREASING PRECIPITATION POTENTIAL AND WINDS. AD
&&

.PIH WATCHES/WARNINGS/ADVISORIES...NONE.
