Area Forecast Discussion
National Weather Service Hastings NE
117 AM CDT Sun Oct 23 2016

Issued at 611 PM CDT Sat Oct 22 2016

Updated the forecast to end the Red Flag warning as winds have
begun to diminish this afternoon and relative humidity values are
recovering above 20 percent. No other significant changes to the
forecast are necessary at this time.


.SHORT TERM...(This evening through Sunday)
Issued at 359 PM CDT Sat Oct 22 2016

Clear skies continue across the area this afternoon. Winds from the
south have warmed up temperatures this afternoon and the mixing has
lowered relative humidity. The red flag warning will continue for
the afternoon. Surface analysis has a surface low in western South
Dakota with trough through western Nebraska and Kansas.

The surface low and a cold front is expected to move through the
forecast area during the night. There is a weak upper level wave
with it as well, but still expect there to be mostly clear skies and
dry conditions. Behind the front on Sunday winds will be from the
north and temperatures will be a little cooler.

.LONG TERM...(Sunday night through Saturday)
Issued at 359 PM CDT Sat Oct 22 2016

Sunday night through Monday night there is a surface high that
settles into the area Sunday night, then moves to the east Monday.
There will be south winds as the high moves to the east and there
will be an increase in moisture through the period. Clouds will
increase Monday afternoon into Monday night.

An upper level wave will move into the area Tuesday and Tuesday
night. A cold front will also move through and the models have some
slight timing differences with the front. This will also impact
thunderstorm development. The thunderstorms are more likely during
the afternoon and evening near the front.


.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Sunday night)
Issued at 112 AM CDT Sun Oct 23 2016

The primary aviation concern will center on the strong low level
wind shear this morning. Initially it is a strong southwesterly
low level jet out ahead of the cold front and then there will be a
strong northerly wind at about 1,500 ft AGL behind the cold front.
That wind shift will generally occur between 2-4am. VFR ceilings
and visibility are expected.
