A return to clouds and precipitation is expected across Western Wyoming early this coming week as very moist air spreads eastward from the Pacific. However as the weeks progresses the air mass is expected to dry leading to a precipitation free and relatively mild Thanksgiving day. In fact the further south you go the warmer it gets, with potentially record setting temperatures near 90F in the Phoenix Area.
The building of a large high pressure system aloft over the Southwest by mid week shifts the storm track mainly to the north of Wyoming.
