.DISCUSSION...
Issued at 332 AM CDT Sat Jul 5 2025

A diffuse, slow moving cold front extended south across central
Kansas this morning. A shortwave trough was also located across
the region which along with a 30-40kt 850mb LLJ was aiding in
persistent convection within an atmosphere characterized by
500-1000J/KG of CAPE but modest shear of less than 20kts. PWATs
were likely near record values at or just above 2" and freezing
levels were at or above 15kft so storms will likely produce
heavy rainfall rates of 1-2"/hr this morning.

Expect the greatest coverage of storms/precip to occur north of
I-70 this morning but any severe weather risk appears very low
this morning given poor lapse rates and weak shear. As the mid
level wave moves to the northeast of Kansas, the 850mb jet
should also weaken and translate away from the area later this
morning. This should cause the precip coverage to wane by
late morning or early afternoon. Meanwhile, the slow moving
cold front will sag southward and should be the focus for
renewed scattered storms this evening. MLCAPE of 2000j/kg or
higher and some mid level drying behind the wave may aid in
increasing the risk for damaging winds in any of the stronger
storms this evening. The coverage and duration of any storms
remains in question however as the wave is departing and heights
are beginning to rise tonight so we expect any severe risk to
diminish by midnight.

The front will sag into southeast Kansas on Sunday with some
lingering low chances for storms in that area. Otherwise, most
areas should be dry with weak high pressure in place.

Sunday night into Monday...another complex of storms may develop
across Nebraska late Sunday and move southward. 850mb winds are
weak across the area and do not favor sustaining any MCS this
far east so would expect that batch of storms to remain west of
the CWA or weaken as it moves southeast.

The remainder of the week will feature continued weak
disturbances moving just north of Kansas in a somewhat zonal to
northwest flow regime. That suggests at least daily/nightly
chances for storms.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1155 PM CDT Fri Jul 4 2025

Expect VFR conds to prevail through much of the forecast period.
Scattered showers and ceilings around or just above 4kft may
arrive around the TAF sites after 10z this morning but coverage
is expected to gradually diminish so confidence is low to insert
anything more than vcsh at this time. There will be a break in
any precip at least from mid morning through late afternoon with
better chcs for more scattered tsra after 00z this evening and
those storms would move north to south through 6z before
diminishing thereafter.
