239 PM CDT Wed Aug 9 2017

.SHORT TERM...(This evening through Thursday)
Issued at 239 PM CDT Wed Aug 9 2017

There will be a few early evening storms possible in the far
southern counties. Then, overnight, the surface front will stall
in southern Nebraska as monsoonal moisture is drawn into Colorado
and Wyoming. A northern stream disturbance will move into
Wyoming. This will bring a slight chance for showers late tonight
to the panhandle and western sandhills. This disturbance will
move through western and southwest Nebraska Thursday. The highest
chances near 50 percent will be across the southeast panhandle
into southwest Nebraska during the afternoon. A stronger belt of
500 mb winds around 40 kts will be supportive of a few strong
storms near and south of Interstate 80. also, with ample moisture
available (PWATS increasing to around 1.25 inches) locally heavy
rainfall is possible.

.LONG TERM...(Thursday night through Wednesday)
Issued at 239 PM CDT Wed Aug 9 2017

Thursday evening, most of the activity should slide south of the
area. There will still be a 20 to 30 percent chance in the evening
across the southwest.

On Friday, a fairly strong upper trough located across Montana
into the far southern Canadian Prairies, will drop southeast and
bring good chances for thunderstorms beginning Friday afternoon,
and continuing into Saturday. Chances are around 50 percent most
areas, with likely pops in the southeast half of the area. A few
strong storms are possible, mainly south of highway 2. in
addition, heavy rainfall may be more widespread with this system,
from the latest model output.

Chances continue Sunday through Wednesday. The northern stream
will be active across the northern tier of the U.S., bringing in
weak fronts every few days. With northwest flow aloft maintained,
this will will bring the best chances during the afternoon and
evening hours. Highs in the mid and upper 70s Sunday warm into the
low to mid 80s Tuesday and Wednesday.
