.SHORT TERM...TONIGHT THROUGH MONDAY...WARM AND DRY S-SW FLOW
THIS AFTERNOON WITH LATEST TEMPS IN THE 60S AND 70S. COLD FRONT
NEAR THE CASCADES IN OREGON IS STILL ON TRACK TO PUSH THROUGH SE
OREGON THIS AFTERNOON AND SW IDAHO THIS EVENING. WINDS ARE NOT
EXPECTED TO BE STRONG...GUSTS TO 35 MPH WITH THE FROPA. TIMING OF
THE FRONT IS 7-9 PM IN BOISE AND AROUND MIDNIGHT IN TWIN
FALLS/JEROME. ISOLATED SHOWERS WITH THE FRONT WILL BE LIMITED TO
NORTH OF BAKER AND MCCALL. COOLER AND DRY ZONAL FLOW WILL FOLLOW
ON SUNDAY. TEMPERATURES WILL BE 6-12 DEGREES LOWER...BUT STILL
NEAR OR SLIGHTLY ABOVE NORMAL. GUSTY POST-FRONTAL WINDS EAST OF
BOISE...OTHERWISE WINDS WILL BE LIGHT. WARMER SOUTHWEST FLOW
RETURNS ON MONDAY WITH HIGHS BACK ABOVE NORMAL /60S AND 70S/ AS
THE NEXT COLD FRONT APPROACHES THE WEST COAST. A SMALL AREA OF
PRE-FRONTAL MOISTURE AND INSTABILITY WILL RESULT IN A SLIGHT
CHANCE OF AFTERNOON SHOWERS SOUTH OF TWIN FALLS.

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...UNSETTLED WEATHER ON
THE WAY FOR SOUTHWEST IDAHO AND SOUTHEAST OREGON. THE UPPER LEVEL
RIDGE WILL MOVE EAST MONDAY NIGHT AS A BROAD UPPER LEVEL LOW
SLOWLY MOVE TOWARD THE PACIFIC NORTHWEST FROM THE GULF OF ALASKA.
GUSTY WINDS...SHOWERS AND MUCH COOLER TEMPERATURES ARE EXPECTED
WITH THIS SYSTEM...AS MUCH AS 20 DEGREES COLDER TUESDAY FROM
MONDAY TEMPERATURES. SNOW LEVELS WILL DROP TO 4000 FT MSL BY
WEDNESDAY MORNING BEFORE COMING BACK UP TO AROUND 6000 FT MSL FOR
THE REST OF THE EXTENDED PERIOD. THURSDAY LOOKS DRIER AS THE
REGION TRANSITIONS THROUGH A SHORTWAVE RIDGE INTO ANOTHER POTENT
PACIFIC TROUGH WHICH ARRIVES BY FRIDAY FOR ANOTHER ROUND OF
PRECIPITATION AND BELOW NORMAL TEMPERATURES.
