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.

tornado moved northeast and caused its most intense damage... low
end EF-1... at the intersection of County Highway 418 and 437. In
this area several large trees were either uprooted or snapped
halfway up the trunk. The tornado moved northeast to Highway mm
where it tore about one-quarter of the tin roofing off a farm
building and damaged some trees. The tornado dissipated as it
crossed Highway mm

The thunderstorm continued east northeast and caused considerable
wind damage in Hannibal. The damage area was roughly from Highway
mm north to Hannibal/La Grange College. One building at the
College had a portion of its roof torn off. Numerous trees were
uprooted or snapped along Palmyra Road/mark Twain Avenue. A three
story brick building in downtown Hannibal on Main Street had a
wall collapse and about half of its roof torn off. Wind gusts in
this area were likely around 100 mph. Tree damage was common west
of the downtown area to Highway 61 and then west of 61 along West

numerous large trees branches down. One home near Apollo Lake had
windows broken by flying debris. A small building lost part of its
roof on the south side of Hannibal near Highway 61 and Market street.

Service survey team and is subject to change pending final review
of the event and publication in National Weather Service storm
