Issued at 254 PM CDT SAT SEP 24 2016

A large swath of showers and thunderstorms has developed this
afternoon stretching from TX into central KS and into the Dakotas
ahead of a deep upper-level trough over the Intermountain West. Most
of this activity is being driven by an extensive low-level jet
stretching across the Plains. This jet and its associated
precipitation will slowly work their way eastward late this evening,
with the axis of strongest convergence/isentropic ascent not reaching
the I-35 corridor until after 9 pm or so. However, the airmass out
ahead of this activity remains unstable and uncapped, and with weak
warm air advection continuing into the evening, isolated to scattered
thunderstorms remain a possibility across the entire forecast area
until the main axis of precipitation moves in later tonight.

Occasional showers and embedded thunderstorms will slowly track
eastward across the entire forecast area overnight into early Sunday.
Limited instability during this time will prevent much threat for
strong storms or widespread heavy rain, although precipitable water
values approaching 2 inches could lead to a few pockets of an inch or
two of rainfall especially over eastern KS and northwest MO.
Generally, however, rainfall amounts look to stay near or below a
half inch for most locations. Showers and a few storms will continue
into Sunday morning until the main cold front swings through during
the late morning and early afternoon hours.

By Monday an extensive area of high pressure will build into most of
the central U.S. with its influence continuing into most of the rest
of the week. The result will be dry conditions for the remainder of
the week while temperatures stay close to average for late September.

Band of numerous showers and embedded thunderstorms over central KS
will make slow eastward progress, and much of this activity will not
cross into western MO until after dark. However, a few isolated to
scattered weak thunderstorms are possible ahead of this line as early
as 3 to 4 pm for the KC area. Off-and-on showers and a few storms
will continue overnight until a cold front swings through around
sunrise.
