between systems Sunday. Upper low well to the west while the ridge is in
the foothills of the Rockies. This will bring a dry day with mild
temperatures and abundant sunshine. As a result, mixing level rises
fairly rapidly during the day. Down side is that mixing worsens even more
rapidly in the evening and becomes very poor overnight. Transport light
early but sets up a southwest to westerly flow during the afternoon.
Mixed bag for dispersion. Poor until the wind increases, good to
excellent in the afternoon but becoming poor again in the evening.<o:p></o:p></span></p>

Wednesday but temperatures will be on the cool side. Likely to see some
snow at the higher elevations late Tuesday and Wednesday. Dispersion
improves with the trough but begins to worsen again Wednesday.<o:p></o:p></span></p>
