Areas affected...far eastern Nebraska into western Iowa
Concerning...Severe Thunderstorm Watch 407...
Valid 130211Z - 130415Z
The severe weather threat for Severe Thunderstorm Watch 407
continues.
SUMMARY...The threat of large hail persists over a small area of
eastern Nebraska into western Iowa in the near term. Storms will
likely shrink in size during the next 1-2 hours.
DISCUSSION...A pair of large supercells with history of very large
hail remain over western IA into far eastern NE near the Omaha area.
The 00Z sounding from OAX shows a rather deep moist layer up to
nearly 700 mb, not far from the LFC, with favorable deep-layer
shear.
Given the loss of heating, the cooling boundary layer will gain
convective inhibition relatively quickly, perhaps in the next hour,
which should result in a weakening trend with these cells. Until
then, hail will remain likely through about 03-04Z, with locally
gusty winds as well prior to
