STRONG SOUTHERLY WINDS WILL EXIST AHEAD OF THE ASSOCIATED COLD
FRONT PASSAGE AROUND MID TO LATE MONDAY AFTERNOON. PEAK WINDS AHEAD
OF THE FRONT WILL OCCUR BETWEEN 1100-1600 MDT...WITH A PERIOD OF

AROUND 1600-1900 MDT. THE CHANCE FOR WETTING RAINS WILL BE SMALL
DUE TO LIMITED AVAILABLE MOISTURE AND THE CONVECTIVE NATURE OF THE
PRECIPITATION. SUBSTANTIALLY COOLER AND MORE STABLE AIR WILL FOLLOW
THE COLD FRONT FOR LATE MONDAY NIGHT THROUGH TUESDAY.
