Heavy rainfall from monsoon thunderstorms may bring isolated flash and urban flooding to the Desert Southwest. A near-stationary front will bring numerous showers and thunderstorms to much of the Mid-Atlantic and Southeast. Tropical wave (AL94) is likely to become a depression. Significant uncertainty remains in the track and intensity, but chances for impacts to the Southeast are increasing. Read More >

At approximately 6:55 PM CDT on Thursday,
April 17, a tornado developed near Highway
133, and appeared to produce first damage by
snapping limbs in an area of trees. The
tornado moved to the east, impacting trees,
homes, and destroying a garage near 108th
Street. It damaged trees along Little
Papillion Creek and then impacted a home and
large garage near 84th Street, south of
Dutch Hall Road. This was the point along
the tornado track where the most intense
damage was observed, as a well-built
all-brick home was destroyed with only some
walls still standing. Tree damage near the
site, as well as the destruction of a large,
well-built garage, supported the estimate of
high-end EF-2 to low-end EF-3 damage at this
location. The tornado proceeded to destroy
another large shed, and remove the roof from
a brick home a half mile to the east. It
then destroyed a very large garage-type
building in-between two homes at 78th Street
south of Dutch Hall Road. The tornado passed
directly between the homes, causing
extensive tree damage, lifting and moving a
full-size pickup truck approximately 30
yards, and throwing large trees nearly a
quarter of a mile downstream. The tornado
weakened slightly but damaged several
outbuildings and trees near 72nd Street. At
that point, it began to move more
northeasterly, snapping several trees and
flipping recreational vehicles at Nashville,
NE. It directly impacted another home,
destroying two outbuildings and causing tree
damage near Country Road P38. The tornado
impacted one more home and destroyed another
outbuilding near Country Road P51 before
dissipating in an open field at
approximately 7:15 PM CDT. The tornado is an
EF-3 with estimated maximum wind speeds
based on damage of 140 mph. The maximum
track width was approximately 170 yards and
the track length approximately 8.3 miles.

until cross U.S. 275, producing EF-0 damage
to roofs and farm outbuildings just south of
130th Street, reaching a width of about 1/4
mile. Based on video, the tornado weakened
briefly east of U.S. 275 until it crossed
280th Avenue, where it again reached a width
of about 1/4 mile and strengthened again
before crossing 290th Avenue, producing EF-0
damage to trees and flipping irrigation
pivots. The tornado continued until about
the intersection of 300th Avenue and 140th
