The southern extent of the upper trough axis will swing across

of Arnold through Valentine, and 30 to 50 percent to the west.
Then mainly a slight chance east of highway 83 after midnight.
Clearing skies after midnight in the eastern panhandle and western
sandhills for lows in the lower to mid 30s. This will allow for
areas of frost to occur beginning 07z through 13z Tuesday. Have
issued a Frost Advisory for the northwestern counties including
Sheridan, Garden, Grant, and western Cherry county. Further east,
lows in the upper 30s to lower 40s as cloud cover holds on

Dry conditions expected Wednesday and Wednesday night as the

Saturday, a closed low in Utah Thursday will lift slowly northward
into Montana by Saturday. This will bring a slight chance for
showers Thursday and Thursday night southwestern areas. A deeper
upper trough will dig from the Pacific NW Friday across the
Northern and Central Rockies By Sunday. This will provide at least
a slight chance for showers to portions of the area Friday through

70s through the entire extended period, fairly close to normal for
