.SHORT TERM...(This evening through Friday)
Issued at 308 PM CDT Thu Aug 10 2017

This evening, the scattered showers and storms currently over
north central Colorado may move into southwest Nebraska, south of
I80. Overnight, skies will become mostly clear. Patchy fog
expected from the southeast panhandle into the southwest, which
seems plausible from the recent rainfall today. Lowest
visibilities should be west of Ogallala toward Big Springs and
Chappell, lasting until 15z Friday.

Friday afternoon, a disturbance in northwest flow will move move
into western South Dakota and the Nebraska panhandle. A 20-30
percent chance mainly west of highway 61 after 21z. Otherwise a
partly to mostly sunny day with warmer highs around 80.

.LONG TERM...(Friday night through Thursday)
Issued at 308 PM CDT Thu Aug 10 2017

Likely pops Friday evening in the eastern panhandle, with chances
spreading east overnight. A few strong storms possible Friday
evening near and west of Highway 61. On Saturday, a fairly strong
upper trough located across Montana eastward through North Dakota,
will drop southeast and bring good chances for thunderstorms
beginning Saturday into Saturday night. Chances are around 50
percent most areas, with likely pops in some areas. Some strong
storms are possible, mainly west of Valentine through Broken Bow.
In addition, heavy rainfall may be fairly widespread with this
system, from the latest model output. According to WPC, there is a
slight risk for excessive rainfall east of the panhandle.

Thunderstorm chances continue Sunday through Thursday. Coverage
looks to be much more limited however. Some upper troughing will
occur across the western U.S., with fairly zonal flow across the
Plains. Highs in the upper 70s to lower 80s Sunday through Tuesday
warm into the low to mid 80s Wednesday and upper 80s by next
Thursday.
