Weather Summary

Weather Underground midday recap for Tuesday, May 21, 2013.

After a devastating severe weather day in the Plains on Monday, severe weather began to fire up again across the nation's mid-section on Tuesday.

The nearly stationary low over the Northern Plains showed signs of gradual weakening as it shifted eastward toward the Mississippi River Valley on Tuesday, while the system's associated cold front trailed southwestward from the low across the Mid-Mississippi Valley through the Southern Plains. Favorable energy and conditions ahead of the cold front combined with the moisture laden conditions of the nation's mid-section set the stage for multiple clusters of thunderstorms to develop from the Midwest into the Ozarks and the Southern Plains. Portions of north-central/northeastern Texas, southern Arkansas, northwestern Louisiana and far southeastern Oklahoma remained at moderate risk of severe thunderstorm activity as environmental conditions remained favorable for tornadoes, damaging wind gusts, and very large hail. In particular, substantial severe weather was expected across north-central Texas to the

ArkLaTex region this afternoon and evening. Areas surrounding this moderate risk region from the Southern Plains to the Tennessee/Ohio valleys and the Lower Great Lakes/Northeast remained at slight risk of severe thunderstorm development with hail, damaging wind gusts, and isolated tornadoes. In addition to severe storms, heavy rains created chances of flood and possible isolated areas of flash flooding from parts eastern Oklahoma through northern Arkansas.

Meanwhile, areas of heavy rain and widely scattered showers continued near the low in the Northern Plains and Upper Mississippi Valley and near and to the north of a nearly stationary frontal boundary extending out ahead of the system from the Great Lakes into the inland areas of the Northeast. Continued precipitation in already saturated areas of the Northern Plains and Upper Midwest maintain flood concerns from parts of North Dakota into northern Wisconsin.

Elsewhere, scattered showers and thunderstorms picked up across the Mid-Atlantic and southeastern corner of the nation through the afternoon.

Mobile & Email Alerts Statement as of 10:47 PM CDT on May 21, 2013

... NWS damage survey for 05/20/2013 tornado event...

.Wyandotte tornado 1...

Rating: EF-2
estimated peak wind: 115-125 mph
path length /statute/: 10 miles
path width /maximum/: 800 yards
fatalities: 0
injuries: 0

Start date: may 20 2013
start time: 625 PM CDT
start location: 4 N Fairland / Ottawa County / OK
start lat/lon: 36.8129 / -94.8461

End date: may 20 2013
end time: 640 PM CDT
end location: 4 NE Wyandotte / Ottawa County / OK
end lat/lon: 36.8298 / -94.6706

Survey summary: this tornado snapped or uprooted numerous trees
and damaged numerous homes. The most significant damage was
located near the area where the tornado crossed Highway 137 where
a metal building was severely damaged and several homes were
damaged. Many Hardwood trees were also snapped in that area.

.Wyandotte tornado 2...

Rating: EF-1
estimated peak wind: 100-110 mph
path length /statute/: 9.5 miles
path width /maximum/: 600 yards
fatalities: 0
injuries: 0

Start date: may 20 2013
start time: 632 PM CDT
start location: 2.8 NW Wyandotte / Ottawa County / OK
start lat/lon: 36.8128 / -94.7701

End date: may 20 2013
end time: 642 PM CDT
end location: 0.5 se Seneca / Newton County / MO
end lat/lon: 36.8359 / -94.6062

Survey summary: this tornado damaged several houses... damaged
barns or outbuildings... and snapped or uprooted a number of trees.
It dissipated over the south side of Seneca Missouri after
snapping or uprooting several trees as it crossed the state line
and crossed Highway 43. Several eyewitnesses north of Wyandotte saw
two tornadoes approaching from the west and radar data as well as
damage patterns support that conclusion. In addition... there was
lots of evidence of straight-line wind damage south of the
tornado paths as the Bow echo storm surged east as it approached
the state line.

.Talala area tornado...

Rating: EF-1
estimated peak wind: 90-100 mph
path length /statute/: to be determined
path width /maximum/: to be determined
fatalities: 0
injuries: 0

Start date: may 20 2013
start time: to be determined
start location: to be determined
start lat/lon: to be determinded

End date: may 20 2013
end time: to be determined
end location: to be determined
end lat/lon: to be determined

Survey summary: this tornado was photographed by a number of
witnesses and apparently remained over open country for much of
its lifecycle to the northwest of Talala. However... the survey
team was able to get a preliminary assessment on this area today
just before sunset and did find one home that had been hit...
probably toward the end of the tornado lifecycle. This home had
roof damage... windows broken out... chimney torn off the roof and a
nearby metal framed barn damaged with Bay doors blown out on both
sides. This may have been the final tornado of several produced by
the storm that first produced a tornado south of Avant in Osage
County. Further surveys will be done in this area on Wednesday and
photos and video from spotters and chasers will be reviewed to
help finalize this portion of the event.

Ef scale: the Enhanced Fujita scale classifies tornadoes into the
following categories.

EF0... weak... ... 65 to 85 mph
EF1... weak... ... 86 to 110 mph
EF2... strong... .111 to 135 mph
EF3... strong... .136 to 165 mph
EF4... violent... 166 to 200 mph
EF5... violent... >200 mph

Note:
the information in this statement is preliminary and subject to change
pending final review of the events and publication in NWS storm
data.
