.DAY ONE...TODAY AND TONIGHT

WIDESPREAD PRECIPITATION IS EXPECTED ACROSS SOUTHEAST IDAHO DURING

IN THE CENTRAL MOUNTAINS TODAY.  ELEVATED SNOW LEVELS HOWEVER WILL
RAISE THE CONCERN FOR RAPIDLY RISING RIVERS. RIVER STAGE FORECASTS
ARE BELOW WARNING LEVELS WITH THE EXCEPTION OF THE PORTNEUF WHICH
MAY REACH FLOOD STAGE LATER THIS WEEK.  WITH RECENT AND EXPECTED
RAINFALL WILL ALSO NEED TO MONITOR THE BIG AND LITTLE WOOD RIVER
REGION. A STRONG UPPER LEVEL JET WILL ALSO BRING ELEVATED AWARENESS
FOR MODERATE TO STRONG THUNDERSTORM DEVELOPMENT FROM THE SNAKE
PLAINS EASTWARD TODAY.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH WEDNESDAY

THE EXITING PACIFIC STORM AND FALLING SNOW LEVELS WILL HEIGHTEN THE
POTENTIAL FOR HEAVY SNOW ACROSS THE EASTERN HIGHLANDS INTO THURSDAY.
A WINTER STORM WATCH CONTINUES FOR THAT REGION.
