SATELLITE IMAGERY SHOWS NORTHWEST FLOW ACROSS IDAHO WITH UPPER
HIGH CENTERED OFF THE CALIFORNIA COAST TODAY. HIGH CLOUDS
STREAMING ACROSS THE REGION OTHERWISE PATTERN IS MUCH QUIETER
TODAY COMPARED TO PREVIOUS DAYS, ALBEIT MUCH COOLER. SOME GUSTY
WINDS ARE STILL IN PLACE, BUT MAX GUSTS TODAY LOOK TO TOP OUT AT
25-35 MPH, WHICH IS BELOW WHAT SUSTAINED SPEEDS REACHED ON
SATURDAY. WEAK SHORTWAVES DRIVING OVER THE TOP OF THE BUILDING
RIDGE OF HIGH PRESSURE TONIGHT INTO TUESDAY COULD PRODUCE A FEW
LIGHT SNOW SHOWERS MAINLY ACROSS THE ISLAND PARK HIGHER
ELEVATIONS AND PORTIONS OF THE CENTRAL MOUNTAINS. LIQUID QPF
AMOUNTS REMAIN EXTREMELY LIGHT, AND IMPACTS ARE EXPECTED TO BE
MINIMAL. LOOKING AHEAD INTO THE WEEK, UPPER RIDGE CONTINUES TO
STRENGTHEN OVER THE WESTERN STATES, LEADING TO A PERIOD OF VERY
STRONG WARMING FOR EAST IDAHO. BY WEDNESDAY, ALMOST ALL LOWER
ELEVATIONS WILL BE INTO THE 70S BASED ON THE DETERMINISTIC NBM.
IT IS IMPORTANT TO NOTE THAT THE DETERMINISTIC VALUES ARE
RUNNING SEVERAL DEGREES BELOW THE ENSEMBLE SPREADS.
PROBABILISTIC DATA SUPPORTS INCREASING CHANCES FOR PORTIONS OF

LIKELY BE THREATENED BEGINNING AS EARLY AS TUESDAY AND
CONTINUING THROUGH THE REMAINDER OF THE WORK WEEK.
