UPDATE...
A WEAK SHORT WAVE IS STILL FORECAST TO MOVE INTO SOUTHWEST MONTANA
THIS AFTERNOON AND COULD TRIGGER A FEW SHOWERS OVER FAR SOUTHWEST
MONTANA. THESE SHOWERS ARE HANDLED WELL BY THE CURRENT FORECAST.
DID LOWER SKY COVER ALONG THE EAST SLOPES FOR THIS AFTERNOON BASED
ON LATEST GUIDANCE AND EXPECTED STRONG DOWNSLOPE. SPEAKING OF
DOWNSLOPE INCREASED THE WINDS SOME OVER THE EAST SLOPES FOR THE
REST OF THIS MORNING AND ALSO DURING THE AFTERNOON. BUT IT LOOKS
LIKE WINDS SHOULD STAY BELOW HIGH WIND CRITERIA. BLANK
