Weather Summary
Kari Kiefer
Weather Underground Forecast for Thursday, May 23, 2013. A strong, large storm will continue making its way through the eastern third of the country on Thursday, producing more, active weather east of the Mississippi Valley. While the active weather is not likely to produce the severe thunderstorms that have greeted the country over the past several days, scattered thunderstorms will be likely, especially in the Southeast. In addition, moderate to occasionally heavy rain will move through the Northeast, followed by cool showers in the Ohio Valley and Upper Midwest.

Meanwhile, some moisture pushing into the Southern Plains could possibly instigate some severe thunderstorms in northern Texas and western Oklahoma. Due to this possibility, the Storm Prediction Center has issued a slight risk of severe weather in the area for Thursday. This means residents in the area should prepare as if severe weather will develop, making any necessary preparations to protect life and property.

Also, a seasonably strong low pressure system will linger over the Pacific Northwest today, allowing wet weather to continue in the area. While rain will be the overwhelming precipitation due to this storm, a few snow showers will be possible in the higher elevations of the Cascades.

Additionally, rain will also spread as far east as central Montana.

The Northeast will rise into the 70s and 80s, while the Southeast will see temperatures in the 80s and 90s. The Southern Plains will rise into the 80s and 90s, while the Southwest will see similar temperatures.

Mobile & Email Alerts Statement as of 7:25 am PDT on May 23, 2013

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. Thunderstorms can be a mariners worst nightmare. They
can develop quickly and create dangerous wind and wave conditions.
Thunderstorms can bring shifting and gusty winds, lightning,
waterspouts, and torrential downpours which can turn a days pleasure
into a nightmare of distress. There are no specific warnings or
advisories for lightning but all thunderstorms produce lightning. A
lightning strike to a vessel can be catastrophic, especially if it
results in a fire or loss of electronics. If your boat has a cabin,
then stay inside and avoid touching metal or electrical devices. If
your boat does not have a cabin, stay as low as you can in the boat.
Boaters should use extra caution when thunderstorm conditions exist
and have a plan of escape. Mariners are especially vulnerable as at
times they may unable to reach port quickly. It is therefore
strongly recommended you do not venture out if thunderstorms are a
possibility. If you do venture out and recognize thunderstorms
nearby, head to port or safe shelter as quickly as possible.
Ultimately, boating safety begins ashore with planning and training.
Keep in mind that thunderstorms are usually brief so waiting it out
is better than riding it out. To learn more, visit the National
