Weather Summary

Weather Underground Forecast for Monday, May 20, 2013.

Heavy rains and severe thunderstorm activity will continue for areas of the Plains into the Midwest on Monday as a broad, nearly stationary low sits over the Northern Plains. As the system lingers, ample moisture and energy will stream northward from the Gulf of Mexico, while an associated cold front extends from the low into Iowa and back across the Central and Southern Plains. The sharpening cold front combined with a dry line in the Southern Plains and the moisture laden conditions of the region will allow for multiple clusters of thunderstorms to develop across the Plains and into the Mid-Mississippi Valley. Portions of Oklahoma, southeastern Kansas, extreme, northwestern Arkansas, an southwestern Missouri are at moderate risk of severe thunderstorm activity as environmental conditions remain favorable for strong tornadoes, damaging wind gusts, and very large hail. Areas surrounding this moderate risk region from the parts of the southwestern Texas into the Upper Great Lakes are at slight risk of severe thunderstorm development with hail and isolated tornadoes.

Meanwhile, areas of heavy rain and widely scattered showers will persist near the low and it's associated warm front in portions of the north-central U.S. Continued precipitation in these already saturate areas combined with rapid runoff will continue flood concerns from parts of North Dakota into northwestern Wisconsin.

Elsewhere, scattered showers and thunderstorms are expected in the Mid-Atlantic and southeastern corner of the nation as a weak upper trough of low pressure drops southward over the region. Locally heavy rain amounts of up to 2 inches may result in areas of minor flooding, especially in poor drainage areas. To the north, additional showers will be possible in the Northeast.

Public Information Statement
Mobile & Email Alerts Statement as of 5:00 am EDT on May 20, 2013

... National safe boating week may 18 through may 24...

This is the third in a daily series of messages produced by the
partnered National Weather Service and National safe boating Council.

The cospas-sarsat system is an international satellite based search
and Rescue system used to locate emergency radio beacons
transmitting on a frequency of 406 megahertz. Since 1982... this
cospas-sarsat system has been instrumental in the Rescue of over 30
thousand individuals worldwide including more than sixty seven
hundred here in the United States. NOAA is the lead representative
for the United States to the cospas-sarsat organization.

Emergency position indicating radio beacons or epirbs are a type of
emergency radio Beacon developed for use in marine environments.

There are two types of epirbs which when equipped with GPS may help
Rescue forces find you more quickly. Category 1 epirbs can be
activated automatically or manually. Category two epirbs can only be
activated manually.

These are becoming increasingly affordable and act as a last line of
defense if disaster strikes.

Once an epirb is purchased..it must be registered. The information
provided for the registration may help Rescue forces find you faster
in an emergency. The information also allows the Rescue coordination
center to determine if a distress alert is real or false and
possibly prevent a needless dispatch for a false alert.

You can Register on line at www.Beaconregistration.NOAA.Gov. For
questions please call 888-212-7283.

For more information on epirbs visit www.Sarsat.NOAA.Gov
