.DISCUSSION...
No fire weather concerns expected this weekend as wetting rainfall
impacts much of the area on Saturday and sub-tropical moisture sticks
around for Sunday. Precipitable water values remain quite high for this
time of year, meaning wetting rainfall will continue through at least
Sunday. Drier conditions start to work back into the region Monday, with
areas west of the Laramie Range starting to see afternoon minimum humidity
values in the 25 to 35 percent range, while areas east remain at and
above about 40 percent. Widespread dry conditions expected to return to
the entire region by Thursday. Winds will be breezy through Wednesday as
is fairly typical this time of year.
