Weather Summary
Weather Underground Forecast for Sunday, May 19, 2013.

Severe thunderstorm activity will persist for the Plains on Sunday as a broad low pressure system continues trekking through the region. The system will move from the Northern Plains and into the Great Lakes, creating two frontal boundaries. The warm front associated with this system will extend eastward over the Great Lakes and into the Northeast, kicking up scattered showers and thunderstorms into Sunday night. At the same time, a cold front extends southward from this system which will move off the Central Rockies and into the Central and Southern Plains. Counter-clockwise flow around this broad system will pull moisture and energy into the Plains from the Gulf of Mexico. This will support moderate to heavy showers and thunderstorms in between these two fronts. This system has a history of severe thunderstorm development across the Northern and Central Plains, thus, there is a moderate risk of severe thunderstorm development with large hail, damaging winds, and multiple tornadoes. These severe thunderstorms will most likely develop across central and eastern Oklahoma, through eastern Kansas, and into western Missouri. A slight risk of severe storm development remains in effect from northern Texas, through southern Minnesota and Wisconsin on Sunday. At the same time, the back side of this system will continue spreading moisture over the Intermountain West and Rockies. This will trigger more showers with isolated thunderstorms over the region through Sunday evening.

Meanwhile in the East, a trough of low pressure slowly moves over the East Coast and maintains shower and thunderstorm activity for the Mid-Atlantic states through the Northeast.

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

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

This boating season make sure that you take advantage of the vessel
safety check program... a free no risk service provided in our area
by the United States Coast Guard auxiliary and the United States
power squadrons.

A qualified vessel examiner will conduct an inspection of all the
required safety equipment carried or installed on a vessel and
certain aspects of the vessels overall condition.

Even if you pay careful attention to safety... dangerous mechanical
problems can crop up on the best maintained boat. That is why the
United States Coast Guard recommends all recreational boats
including personal watercraft... get a free vessel safety check each
year.

A vessel safety check is our best way of learning about conditions
that might put US in violation of state or federal Laws or
worse... create an unsafe condition for ourselves on the water.

If the vessel meets all federal and state requirements... the
examiner will award a vessel safety check decal. If the vessel fails
to receive a decal... no law enforcement action is taken and the
examiner will provide a list of items for correction.
