Weather Summary
Shaun Tanner
Weather Underground Forecast for Sunday, May 20, 2012. The tropical season got off to a bit of an early start on Saturday as a tropical disturbance off the Carolina Coast became Tropical Storm Alberto. The storm is expected to slowly make its way up the eastern seaboard over the next couple of days, possibly skirting the Outer Banks of North Carolina. Rain and thunderstorms could make their way to the Mid-Atlantic coast as the storm moves northeastward. For more information on this storm, please see http://www.wunderground.com/tropical/.

Meanwhile, a cold front will move through the Plains on its way into the Upper Midwest and Mississippi Valley. This front will provide rain and thunderstorms from Oklahoma through Michigan. Some of these thunderstorms could turn severe, so residents in the Plains should stay on alert for any thunderstorm development in their area. Cool air will spill into the Northern Plains and Upper Midwest behind this front, bringing cool overnight temperatures to the Dakotas and Minnesota.

Also, mostly sunny skies are expected for California and the Southwest, making for nice viewing conditions for the solar eclipse. The eclipse will begin just after 5:00 p.m. Pacific time, and should be able to be viewed from California through western Texas.

The Northeast will rise into the 70s and 80s, while the Southeast will see temperatures in the 80s and 90s. The Mississippi Valley will also rise into the 80s and 90s, while the Southwest will see temperatures in the 90s and 100s.

Excessive Heat Watch
Mobile & Email Alerts Statement as of 1:54 AM PDT on May 20, 2012

... Excessive heat watch in effect from Monday morning through
Monday evening...

The National Weather Service in Phoenix has issued an excessive
heat watch... which is in effect from Monday morning through
Monday evening.

* Affected area... the lower deserts of southwest and south central
Arizona... as well as southeast California.

* Temperature... Max temperatures around 108 are expected in and
around Phoenix... possibly exceeding 110 degrees across portions of
southeast California and southwest Arizona.

* Impacts... excessively hot temperatures are dangerous and can
negatively impact the body very quickly. Take the proper
precautions to protect yourself from the heat.

Precautionary/preparedness actions...

Take extra precautions if you work or spend time outside.
When possible... reschedule strenuous activities to early
morning or evening. Know the signs and symptoms of heat
exhaustion and heat stroke. Wear light weight and loose
fitting clothing when possible and drink plenty of water.
If you wear a wide-brimmed hat... your head and body will be
much cooler.

To reduce risk during outdoor work... the occupational safety
and health administration recommends scheduling frequent
rest breaks in shaded or air conditioned environments.
Anyone overcome by heat should be moved to a cool and
shaded location. Heat stroke is an emergency... call 9 1 1.
