LONG TERM [Sunday through Thursday]...
An unsettled weather pattern will begin the period with abundant
moisture in place. An upper trough will approach Sunday and swing
through the region Sunday night scouring out the moisture to our
south and east. Deep layer ridging quickly builds in overhead along
with a very dry airmass Monday into Tuesday. Short term models show
a developing low pressure system over Texas Tuesday that moves into
the Lower Mississippi Valley Wednesday and then becomes vertically
stacked as it lifts northeastward into the Missouri Valley Thursday.
Showers and possible thunderstorms ahead of the associated cold
front should begin to spread into our western zones late Wednesday
sweeping across the remainder of our CWA Wednesday night and
