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.

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 eighteenth through may
twenty-fourth. Emergency position indicating radio beacons are a
type of emergency radio Beacon developed for use in marine
environments. Other types of emergency radio beacons such as
personal locator beacons are available for different applications,
however their effectiveness can be compromised when used in the
marine environment. 406 mega-hertz emergency position indicating
radio beacons are divided into two categories. Category 1 emergency
position indicating radio beacons are activated automatically or may
be activated manually. Category 2 emergency position indicating
radio beacons can only be activated manually. Either of these two
types of emergency position indicating radio beacons may be equipped
with GPS which will help Rescue forces locate you more quickly. As
proven by experience, an emergency position indicating radio Beacon
often serves as the last line of defense when disaster strikes. All
types of emergency position indicating radio beacons are becoming
increasingly affordable and all mariners should investigate
procuring one, especially those operating in harsh environments or
offshore areas. Once your Purchase is made, make certain that you
Register your emergency position indicating radio Beacon, which is
mandatory. The information you provide on your registration may help
Rescue forces find you faster in an emergency. This information also
allows Rescue coordination center personnel to determine if a
distress alert is real or false and prevent the needless dispatch of
Rescue forces to locate a false alert. You may Register online at W

questions, please call 1, 8, 8, 8, 2, 1, 2, 7, 2, 8, 3. For more
