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.

Special Weather Statement
Mobile & Email Alerts Statement as of 3:23 AM PDT on May 21, 2013

... Much cooler weather today snow levels lowering to pass level
tonight...

There will be a drastic change in temperatures today as a cold
low pressure system moves over northwest Oregon. Many locations
will see temperatures 15 to 20 degrees cooler than those
experienced Monday.

Snow levels will start out high... above 8000 feet this morning...
then lower to 4000 feet this evening... and down to 3000 feet by
Wednesday morning. Snow accumulations are expected to remain below
advisory conditions with 2 to 4 inches expected between 3000 and
6000 feet Tuesday night through Wednesday. Higher snow amounts... 6
to 9 inches are likely above 6000 feet.

Showers at lower elevations may include small hail this
afternoon... potentially resulting in extra slick roadways. There
may also be a few thunderstorms this afternoon and evening.

Drivers should use extra caution... especially while driving over
the Cascade passes or encountering small hail on the roads. Slow
down and leave plenty of room between cars.

Hikers and climbers venturing into the mountains will want to be
prepared for a quick change to cold and wet weather today...
especially following a deceptively warm and sunny Monday. From 3000
feet and up... be prepared for accumulating snow starting this
evening and continuing through at least Wednesday night.
