AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
1039 AM MDT MON AUG 28 2006

.DISCUSSION...UPDATED FORECASTS AVAILABLE. MINOR ADJUSTMENTS TO
TEMPERATURES TODAY AS THERMAL AXIS WILL BE NEAR ORE-IDA BORDER
AROUND 6 PM. BOISE SOUNDINGS 00-12Z AND DESCENDING AIRCRAFT AT 5Z
INDICATE 13C OR WARMER TEMPERATURES AT 700 MB THIS AFTERNOON WHICH
SUPPORTS 96F OR WARMER AT BOISE. SOUTHEAST WINDS WILL PERSIST
ADDING A DOWNSLOPE FACTOR THROUGH THE IDAHO TREASURE VALLEY.
UPDATED TEMPERATURES ACCORDINGLY. THERMAL AXIS OVER S CENTRAL
IDAHO LATE TUESDAY MORNING FOR COOLER TEMPERATURES AND SW/W WINDS.
THEN COLD FRONT WITH W TO NW WINDS AND TIGHTER LI PACKING IN NAM40
PLACES COLD FRONT FROM AROUND RIGGINS TO BURNS OREGON AT 00Z/5 PM
PDT TUESDAY EVENING. BY 9 -10 PM CURRENT EXPECTATIONS ARE FOR THE
COLD FRONT BE FROM MCCALL TO ONTARIO-BOI TOWARDS FIELDS. BY 2 AM
THE FRONT SHOULD BE THROUGH TWIN FALLS. EXPECT 2-3 HOURS OF
NORTHWEST WINDS OF 15 TO LOCALLY 30 MPH WITH THE FRONT.
THUNDERSTORM POTENTIAL IS STILL ON THE NORTHERN FRINGE OF ZONES
INCLUDING NE BAKER COUNTY INTO ADAMS AND N VALLEY COUNTY DUE TO
LIMITED MOISTURE WHICH BOTH NAM12 AND GFS SHOW.

&&

.AVIATION...VFR CONDITIONS MOST AREAS UNDER CLEAR SKIES THROUGH
TUESDAY.  MAIN AVIATION CONCERN WILL BE SMOKE FROM WILDFIRES.
VISIBLE SATELLITE FROM LATE LAST EVENING SHOWED SMOKE PLUMES OVER
AREAS OF THE CENTRAL MOUNTAINS OF IDAHO EAST OF THE LONG VALLEY AND
IN SOUTHEAST OREGON TO THE NORTHWEST OF KREO.  CAN EXPECT AREAS OF 6
TO 10SM IN SMOKE OVER SOUTHEAST OREGON AND SOUTHWEST IDAHO WITH
SMOKE LAYERS TO AROUND 15000 FEET MSL.  LATE NIGHT AND EARLY MORNING
VALLEY INVERSIONS WILL PRODUCE ISOLATED IFR CONDITIONS IN SMOKE
ESPECIALLY IN THE MOUNTAIN VALLEYS EAST OF KMYL.

&&

.PREV DISCUSSION...
SHORT TERM...UPPER RIDGE CONTINUES TO BUILD OVER THE FORECAST AREA
TODAY WITH CLEAR SKIES AND VERY WARM TEMPERATURES.  TODAY IS
EXPECTED TO BE THE WARMEST DAY DURING THIS LATEST RUN OF HOT TEMPS
WITH READINGS TOPPING OUT IN THE MID TO UPPER 90S ACROSS THE
TREASURE VALLEY OF SOUTHWEST IDAHO AND EASTWARD INTO THE SNAKE RIVER
CANYONS. RIDGE AXIS MOVES EAST OF THE CWFA ON TUESDAY AS A VIGOROUS
TROF FROM THE EASTERN PACIFIC APPROACHES THE AREA. TEMPERATURES
AGAIN EXPECTED TO BE ON THE TOASTY SIDE BUT NOT QUITE AS WARM AS
MONDAY WITH THE CORE OF THE HEAT GETTING PUSHED TO OUR EAST. LOW
LEVEL EASTERLY WINDS EXPECTED TO INCREASE TODAY AHEAD OF THERMAL
FEATURE AND THIS SHOULD HELP RAISE HIGH TEMPERATURES EVEN MORE.
ALTHOUGH RECORDS WILL BE APPROACHED IN MANY AREAS...THEY ARE NOT
EXPECTED TO BE BROKEN.

LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...MODELS ARE CONSISTENT IN
MAINTAINING A PROGRESSIVE PATTERN...DRY ACROSS ALL OF OUR CWA WITH
THE EXCEPTION OF OUR NORTHERN EXTREMITIES. ONLY THE DGEX DIFFERS
SIGNIFICANTLY WITH A MUCH SLOWER DEEPER TROUGH CLOSING OFF A LOW
OVER SOUTHWEST IDAHO THURSDAY NIGHT. THIS APPEARS TO BE AN ANOMALY
AS THE OTHER AVAILABLE MODELS ARE QUITE CLOSE MOVING THE TROUGH IN
TUESDAY NIGHT AND OUT ON FRIDAY. THE GFS ENSEMBLES HAVE VERY LITTLE
SPREAD. THE BEST CHANCE OF PRECIPITATION STILL LOOKS LIKE TUESDAY
NIGHT AND WEDNESDAY MORNING ASSOCIATED WITH THE COLD FRONT.
TEMPERATURES WILL START OUT 10 DEGREES BELOW NORMAL WEDNESDAY AND
THURSDAY THEN RECOVER TO A LITTLE ABOVE NORMAL FOR SATURDAY AND
SUNDAY.
