Issued at 249 AM CDT THU SEP 21 2017

Scattered showers and thunderstorms are continuing to develop along
and just north of a front extending across northern Missouri back
into the KC Metro. These are being fueled by the LLJ and will
continue through the morning hours when the focus of the LLJ shifts
north of the area. A upper level ridge residing just east of the
area will retrograde back west bringing the local area under its
influence. This will lead to warm and dry conditions beginning today
and continuing through Sunday. highs will range from the mid 80s to
lower 90s through this timeframe which is 10 to 15 degrees above
normal.

The next weather maker for the area is a upper level trough that
currently resides across the Pacific Northwest. This trough will
slowly dig its way into The Great Basin by Sunday. Sunday night into
Monday the trough will move into the eastern Rockies forcing a cold
front into the Plains. Showers and thunderstorms developing along
this front west of the area on Sunday will move into northwestern
Missouri Sunday night. Monday night the cold front will approach the
area with storms overspreading the entire CWA. The cold front will
then move through the area early Tuesday continuing thunderstorm
chances. The frontal passage will also usher in cooler temperatures
as highs behind the front on Wednesday will be in the low to mid 70s.

VFR conditions are expected for the TAF period. Scattered storms
will continue through the morning mainly for areas east of I-35
and north of HWY 36. They should diminish not long after sunrise.
Patchy fog is possible around STJ, so have put a tempo in for 5SM.
Finally, winds will be southerly as the cold front retreats
north. In addition, winds will pick up during the afternoon hours,
being the strongest in far western MO and eastern KS. Winds will
diminish a little after sunset.
