Weather Summary
Jessica Parker
Weather Underground midday recap for Sunday, May 27, 2012.

Tropical Storm Beryl, located about 110 miles east of Jacksonville, Florida, continued to effect the coasts of northeastern Florida and Georgia on Sunday. Beryl moved toward the west near 10 mph this afternoon, with sustained winds of 43 mph and gust to 52 mph. A westward motion was expected to continue through landfall Sunday night. Tropical storm conditions reached the coast of northeast Florida and southeastern Georgia this afternoon and were expected to continue through tonight. Dangerous surf conditions, including rip currents and storm surge effected coastal areas of northeastern Florida and Georgia, while rain spread inland. For more information on Tropical Storm Beryl, please visit http://www.wunderground.com/tropical.

Meanwhile, to the north, a deep storm from the Northwest moved into the Dakotas. The storm kicked up rain showers and high elevation snow across the Northern and Central Rockies and rain showers in North Dakota. Winter Weather Advisories remained in effect for elevations above 5,000 feet in the Northern Rockies through this evening. New snow accumulations of 1 to 3 inches were anticipated across the lower elevations, with 4 to 6 inches possible for higher elevations through this evening. Moist winds from this system also supported a few light showers and thunderstorms in parts of the Northern Intermountains West and Upper Central Great Basin.

Ahead of the system, an associated warm front reached from the Northern Plains through the Lower Great Lakes. Moisture from the Gulf of Mexico spread across the front and aided in producing rain and thunderstorms across northern Michigan and northwestern Pennsylvania. Behind this activity, a cold front with a wave of low pressure extended southwestward from the low and pushed across the Central Plains. Portions of the Central Plains, from northern Kansas across eastern Nebraska and northwestern Iowa and southwestern Minnesota were at moderate risk of severe weather development. The main concerns with severe storms in these areas were large hail events, damaging wind gusts, and possible tornadoes. A slight risk of severe development surrounded the moderate risk area from the Southern and Central Plains into the Upper Great Lakes. Parts of northeastern Ohio to extreme western New York were also at slight risk of severe weather development with damaging winds and heavy rainfall.

Nowcast as of 5:08 PM EDT on May 27, 2012
Scattered showers and thunderstorms are expected to continue developing across the area through early this evening. The forward motion of these should tend to be slow, and this combined with lots of moisture in the atmosphere will result in locally heavy rain. This can result in some ponding of water on the roads and some flooding in areas of poor drainage. In addition, frequent cloud to ground lightning and small hail are possible with any stronger thunderstorm that can develop.
Excessive heat warning in effect from noon Monday to 7 PM EDT Tuesday...

Excessive Heat Warning
Mobile & Email Alerts Statement as of 3:01 PM EDT on May 27, 2012

... Excessive heat warning in effect from noon Monday to 7 PM EDT
Tuesday...

The National Weather Service in Mount Holly has issued an
excessive heat warning... which is in effect from noon Monday to
7 PM EDT Tuesday. The excessive heat watch is no longer in
effect.

* Heat index values... in the mid 90s due to temperatures around 90
degrees... and dew points in the upper 60s.

* Timing... Monday afternoon through Tuesday evening.

* Impacts... the first heat spell of the season is expected to peak
Monday and Tuesday afternoons with hot and humid conditions
affecting Philadelphia and the surrounding Metro area.
Temperatures on Monday night are not expected to drop much below
the 70 degree mark in urban areas before warming up again on
Tuesday.

Precautionary/preparedness actions...

An excessive heat warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of hot
temperatures and high humidity will create a dangerous situation
in which heat illnesses are likely. Drink plenty of fluids... stay
in an air-conditioned room... stay out of the sun... and check up
on relatives and neighbors.

Take extra precautions if you work or spend time outside. When
possible... reschedule strenuous activity 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.

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.
