Areas affected...parts of northeast Kansas into southeast Nebraska
and vicinity
Concerning...Severe potential...Watch unlikely=20
Valid 041829Z - 042130Z
Probability of Watch Issuance...20 percent
SUMMARY...A few strong to severe storms are possible from northern
Kansas into southwest Iowa late this afternoon. Locally damaging
gusts or a brief/weak tornado cannot be ruled out.
DISCUSSION...Satellite imagery shows an MCV over north-central KS
and into south-central NE, while surface obs show a weak low near
Russell KS. East of this feature, a leading outflow extends from
just west of the NE/IA border southwestward toward the surface low.=20
A warming air mass with southerly winds and upper 60s F dewpoints is
aiding the development of thunderstorms near the boundary in
southeast NE and trailing into north-central KS. The 18Z OAX and TOP
soundings show high PWAT but poor lapse rates overall and lightly
veering winds with height.
As heating continues, the zone ahead of the MCV should continue to
see increased storm coverage and intensity. Low-level shear near the
modifying outflow and ahead of the MCV may increase later today,
possibly supporting isolated supercells. While deep-layer shear is
marginal, the very moist air mass combined with locally stronger 0-1
SRH may support a brief/weak tornado or two. Otherwise, marginal
hail or localized damaging gusts may occur.
