Areas affected...far eastern Nebraska into western Iowa
Concerning...Severe potential...Watch unlikely
Valid 122317Z - 130145Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated cells may produce locally damaging gusts and
hail.
DISCUSSION...Strong heating has led to an uncapped air mass near a
surface trough extending from eastern NE into northwest KS. Visible
imagery and radar indicate storms beginning to form near SUX, with
additional towering Cu into NE along the boundary.
Convergence near this boundary and the uncapped air mass where mid
90s F have been achieved may support isolated severe storms over the
next 1-2 hours. This threat is likely to be short lived as capping
eventually returns, however, moderate mid to high level
northwesterlies will favor southeastward-moving cells capable of
hail, and strong gusts cannot be ruled out given the hot and
well-mixed boundary layer.
