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.

Public Information Statement
Mobile & Email Alerts Statement as of 6:15 PM EDT on May 21, 2013

... The National Weather Service and neracoos (northeastern regional
association of coastal ocean observing systems) continues to observe
may 18th through 24th as National safe boating week...

... Wind and waves...

The following is a safe boating message from the National safe
boating Council and the National Weather Service... reminding you
that National safe boating week is may 18th through may 24th.

National statistics in 2011 indicated that 377 boats went down in
calm seas nationally. However... 287 crafts also sunk under
choppy... rouch or very rough conditions during this period.

Wind and waves affect all types of boats so it is important all
boaters know some basic facts about winds and waves. Wind over water
is usually stronger than over nearby land. Wind is the main factor
in wave development and in general... the stronger the wind... the
larger the waves.

Individual waves are measured from trough to crest. Seas are the
combination of both locally generated wind waves and distantly
generated swell waves and are expressed in the terms of the
significant-wave-height... the mean or average height of the highest
one third of the waves. It approximates the value an experienced
observer would report if visually estimating sea height. When
expressed as a range (for example... seas 3 to 5 ft)... this indicates
a degree of uncertainty in the forecast and/or expected changing
conditions. The danger presented to a vessel is a function of wave
steepness as well as wave height and is unique to each vessel. In
general for small vessels... for a given wave height the danger
increases as the wave period decreases.

"The seventh wave of the seventh set"... an old fisherman's tale?
Perhaps... but it does serve to highlight that wave and surf
conditions are not always constant. In open waters... the occasional
wave may be twice that of the surrounding sea. There are occasional
reports of "rogue" waves of an even greater ratio. Near
shore... waves are even less predictable. So-called "sneaker waves"
can grab the unwary who venture too close to the unpredictable sea.
Mariners may be drawn too close to the surf zone during periods of
relative calm. Proceed cautiously and always be wary of this not
uncommon phenomenon... especially in areas where breaking surf is
known to occur or appears likely.

Winds and waves can change quickly in speed... direction and
steepness so it is important you include a marine forecast in your
preparations for boating.

This message from the National safe boating Council was forwarded to
you by the National Weather Service and the northeast regional ocean
observing system... neracoos.
