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.
