0629 PM CDT Thu Jun 30 2022

Areas affected...Southern NE...Northern KS

Concerning...Severe potential...Watch unlikely

Valid 302329Z - 010130Z

Probability of Watch Issuance...20 percent

SUMMARY...Gusty winds with isolated 50kt+ wind gusts possible this
evening across southern NE and northern KS.

DISCUSSION...Remnants of a very weak mid-level disturbance, that was
over UT Wednesday evening, have progressed into the central High
Plains. This feature appears to be partly responsible for scattered
convection that is evolving across eastern CO into southern NE.
Latest diagnostic data exhibits a well-defined pre-frontal trough
draped from southeast NE into southwest KS. Temperatures have soared
into the 90s to low 100s along this boundary and scattered storms
are now evolving from southeast of HLC to near HJH. Modest mid-level
flow extends to near the NE/KS border where roughly 25k of flow
exists at 500mb. While shear is not that significant, it appears
adequate flow does exist for the maintenance of at least multicell
updrafts and perhaps some clustering along the surface trough. Given
the steep lapse rates gusty winds are certainly possible, along with
isolated 50kt+ winds. Even so, at this time it does not appear the
severe risk will be widespread enough to warrant a watch. Convection
should spread east along the KS/NE border over the next several
hours.
