.SHORT TERM /THROUGH TONIGHT/...
Issued at 256 PM CDT Sat May 18 2024

Late spring Chamber of Commerce weather to continue through tomorrow
as an approaching cold front stalls and retreats northward
overnight. Weak lift with limited moisture will keep storm
potential to the west and north in the vicinity of the front.

Winds that will be initially variable will return southerly while
upper heights climb as a southwest to northeast orientated ridge
builds overhead, pushing high temperatures on Sunday into the
mid to upper 80s.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 256 PM CDT Sat May 18 2024

Unsettled weather to make a return next week starting Sunday night
into Monday as a series of storms dig into the western US then
progress across the nation.  Medium range models are showing
reasonably good agreement in bringing a modest wave under the
developing western trough and across the central Plains early
Sunday. Precipital water will slowly increase taking a "hard way"
trajectory from the western Gulf through Texas across central
Oklahoma into Kansas before curling in time into Missouri.

As a result, models have trended northward with precipitation
chances late Sunday into Monday along the low level convergence
provided by the front west and north of the forecast area as
the front becomes disconnected to the upper wave exiting into
the Great Lakes.

Attention then turns to a more significant storm system that will
cross the Plains Tuesday into Wednesday. As with several past
systems this spring, the associated upper wave will take on a
negative tilt as it moves across Nebraska into Iowa. Models have
trended slower, potentially making this a nocturnal event.

With the Gulf now open instability will be favorable with kinematics
pointing toward organized  severe convection, though at this
time anticipate the better low level shear to be found north of
the forecast area within the SPC Enhanced region.

Several additional waves are then suggested later in the
workweek, and potentially into the Holiday weekend.
