Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
1044 AM CDT Thu Apr 12 2018

A major spring storm system will bring severe weather and heavy snow
to the region. This storm system is moving on to the West Coast and
will develop over the northern Rockies today...slowly shifting east
into the Rockies tonight and the western Plains Friday.

Despite the clouds and cooler east and northeast flow, we do expect
to have above normal temperatures today. The cool front has slipped
to the south and an east or northeast wind will keep the really warm
temperatures to the south in Kansas.

As the low level flow strengthens tonight and the surface low tracks
along the boundary and the warm front lifts northward. Drizzle and
showers will begin to develop this evening. The chance for showers
and thunderstorms will increase overnight. Some of the thunderstorms
may become strong enough to produce hail.

Friday will be an active day with the rain changing to snow in
western Nebraska and there is the potential for all modes of severe
weather developing along the Missouri River into western Iowa during
the afternoon into early evening. Winter storm watches and warnings
are in effect from late tonight into Saturday.

Highs today will range from the lower 60s to the 70s. Lows tonight
will slip back into the 40s for northeast Nebraska, but will only be
in the 50s and 60s for the rest of eastern Nebraska and southwest
