SW Kansas is still under the influence of the deep positively tilted
trough that RAP Mesoanalysis moving across the eastern Great Plains.
On the back side of the system, storms are wrapping around and
dumping more rain into the CWA. These storms/showers have remained
unorganized and very scattered. Due to the limited thermodynamic
potential, the severe threat early this morning is virtually zero.

western Kansas. Currently a Flood Warning is in effect for Trego and
Ness counties. The nearby counties (including Logan and Scott) has
also received large amounts of rain that approach or surpass radar

and cloud cover, Wednesday is expected to be cooler with highs
in the low 70s. This is expected to be the coolest day of the
forecast period before warming back up into the 80s.
Beyond Wednesday, a significant synoptic pattern change is expected
bringing a long and very dry stretch of benign weather. The LREF,

CWA, is poised to create an Omega Blocking pattern. This will

few days. For as long as this pattern dominates, light winds
