Areas affected...Southern Nebraska...Northern Kansas

Concerning...Severe potential...Watch unlikely=20

Valid 090543Z - 090815Z

Probability of Watch Issuance...5 percent

SUMMARY...An isolated large hail threat may continue for a couple
more hours in parts of southern Nebraska and northern Kansas. The
threat should be too marginal for watch issuance.

DISCUSSION...A mid-level shortwave trough is evident on water vapor
imagery over the central Plains. Large-scale ascent associated with
this feature is supporting isolated thunderstorm development over
parts of south-central Nebraska. This activity is located along the
eastern edge of a north-to-south axis of moderate instability,
located from central Nebraska into western Kansas. Short-term model
forecasts suggest the storms will continue to persist over the next
couple of hours and will move south-southeastward into north-central
Kansas. These cells are elevated due to a sharp low-level
temperature inversion, evident on RAP forecast soundings. The
WSR-88D VWP at Hastings suggests that effective shear around 30
knots. This, combined with steep mid-level lapse rates will support
an isolated large hail threat. The threat could persist for a couple
more hours.
