STILL PATIENTLY AWAITING THE ARRIVAL IN SOUTHEAST IDAHO. IN THE
MEANTIME...SATELLITE ALSO SHOWS A MINOR DISTURBANCE IN EASTERN
NEVADA WORKING THIS WAY. NOT MUCH ON RADAR YET BUT HAVE INCLUDED A
SLIGHT CHANCE OF A THUNDERSTORMS IN THE ROCKLAND...POCATELLO AND

NORTH TO ISLAND PARK TOWARDS MORNING. SOUTHERLY WINDS INCREASE
SHARPLY OVER THE CARIBOU HIGHLANDS FRIDAY AFTERNOON...SOUTH WINDS OF
15 TO 25 WITH GUSTS UP TO 35 MPH POSSIBLE. AS FOR THE LOW DIGGING
DOWN THE COAST...WE HAVE A CHANCE OF SHOWERS IN THE CENTRAL
MOUNTAINS AROUND CHALLIS AND STANLEY TONIGHT AND FRIDAY. MODELS
CONTINUE TO SUPPORT THE IDEA OF THIS SYSTEM CROSSING SOUTHEAST IDAHO
SATURDAY SO WE ARE STANDING FIRM ON THE CHANCE OF SHOWERS WITH
ISOLATED THUNDERSTORMS. BY SUNDAY...THIS SYSTEM MOVES NORTHEAST
LEAVING A WEST TO NORTHWEST FLOW PATTERN THAT IS MOSTLY DRY FOR
SEVERAL DAYS...WITH THE EXCEPTION OF A DISTURBANCE OVER NORTHERN
IDAHO MONDAY THAT MAY LEAVE SPOTTY SHOWERS NEAR THE MONTANA LINE.
EARLY NEXT WEEK...CONDITIONS MAY BE DRY ENOUGH FOR MORNING LOWS TO
APPROACH FREEZING AND THREATEN THOSE SENSITIVE GARDEN PLANTS. RS
