Areas affected...southeastern Nebraska...northeastern
Kansas...southwestern Iowa...and northwestern Missouri
Concerning...Severe potential...Watch likely
Valid 260413Z - 260515Z
Probability of Watch Issuance...95 percent
SUMMARY...Scattered strong/severe storms over portions of Nebraska
and southern Iowa should expand southeastward and increase in
coverage over the next few hours. New WW -- extending into
northeastern Kansas and northwestern Missouri, will be needed
shortly.
DISCUSSION...Latest radar loop shows clusters of strong/severe
storms from north-central Nebraska to southwestern Iowa, moving
steadily southeastward. With a moderately unstable airmass (3000 to
3500 J/kg mixed-layer CAPE per RAP-based objective analysis) ahead
of the convection into Kansas/Missouri, and a moderate southwesterly
low-level jet observed, continued southeasterly advance of the
convection is expected. With this area beneath the
leading/expanding edge of stronger mid-level northwesterly flow,
storms should organize/grow upscale with time, propagating southward
with attendant risks for large hail and damaging winds. The
anticipated/expanding risk will warrant new WW issuance shortly.
