.PREV DISCUSSION...
SHORT TERM...WARMING TREND WELL UNDERWAY WITH MAX TEMPS TODAY
EXPECTED ANOTHER 2-6F HIGHER THAN YESTERDAY.  HOWEVER...THIS
INCREASE IS A LITTLE LESS THAN FORECAST BY PREVIOUS MODELS.
TODAY/S MODELS ALSO AVERAGE ANOTHER 2-6F WARMING SATURDAY.  EVEN
THEN THE UPPER RIDGE AXIS AND WARMEST AIR WILL STILL BE TO OUR
WEST.  OCCASIONAL HIGH CLOUDS WILL MOVE THROUGH IDAHO ZONES TODAY
AND SATURDAY IN NWLY FLOW ALOFT.  MODELS HAVE ALSO CONSISTENTLY
RAISED DEW POINTS FOR FRIDAY NIGHT WHICH WOULD LIMIT RADIATIONAL
COOLING COMPARED TO PREVIOUS NIGHTS...I.E. NOT AS COLD.  OUR
FORECASTS REFLECT THIS.  OF COURSE NO PCPN THROUGH SATURDAY.  WINDS
THROUGH SATURDAY WILL BE LIGHT DIURNAL.

LONG TERM...SATURDAY NIGHT THROUGH THURSDAY...A WEAK COLD FRONT
WILL MOVE ACROSS THE REGION LATE SATURDAY NIGHT FOR SLIGHTLY COOLER
MAXIMUM TEMPERATURES SUNDAY AFTERNOON. BY MONDAY THE RIDGE AXIS
BEGINS TO MOVE INLAND FROM THE WEST COAST AND TEMPERATURES TUESDAY
WILL APPROACH 70F IN VALLEY LOCATIONS AS THE RIDGE AXIS SWINGS
ACROSS THE AREA. TUESDAY WILL BE THE WARMEST DAY OF THE PERIOD
BEFORE THE RIDGE BEGINS TO BREAK DOWN BY WEDNESDAY AFTERNOON WITH
INCREASING HIGH CLOUDS AHEAD OF A WEAK TROUGH THAT WILL BRING
SHOWERS ACROSS THE REGION WEDNESDAY THROUGH FRIDAY. SNOW LEVELS WILL
REMAIN QUITE HIGH WITH THIS SYSTEM...6 TO 7K FEET MSL. RIDGING
BEHIND THIS SYSTEM WILL BRING ABOVE NORMAL TEMPERATURES AND DRY
CONDITIONS FOR NEXT WEEKEND.
