.DISCUSSION...High pressure over Texas will slide west over the weekend
forcing monsoonal moisture into central and western UT then curving east
across northern CO and UT. The High center will move to just south of
the Four Corners by Monday cutting off direct northerly flow of moisture
into the area. Instead moisture will recycle around the High through the
week. The general flow aloft will be from the northwest.
