Issued at 300 AM CDT Sat Oct 22 2016

Today and Tonight, An upper level ridge across the southern high

trough will ride around the upper ridge axis across the northern
plains. A weak front will approach north central KS by 12Z SUN.

A lee surface trough will deepen across the central and norther high
plains. The surface  pressure gradient across western and central KS
will be weaker, thus southerly winds will only increase to 10 to 20
MPH with some higher gusts.

east central KS with mid to upper 70s across north central and
central KS. Overnight lows will be mild, with lows only dropping into

From Sunday morning through early afternoon, a frontal passage
will make its way though northeast Kansas. No precipitation is
expected with this front, but light southerly winds will shift out
of the northeast by late Sunday afternoon. This will act to cool
low temperatures slightly from the previous night into the middle
40s early Monday morning. An upper level ridge builds in over the
Central Plains Monday and temperatures stay near 70 degrees.
Southerly winds build back in by Tuesday bringing an influx of
moisture with dewpoints reaching into the 60s. A shortwave quickly
progresses across the central CONUS Tuesday night into Wednesday
morning bringing chances for thunderstorms across the entire area.
A mid-level ridge moves in behind the wave and dry conditions are
expected through Friday. High temperatures from Wednesday onwards
will be in the lower 70s, with lows in the upper 40s to lower 50s.
