Weather Summary
Jessica Parker
Weather Underground Forecast for Monday, May 28, 2012.

Tropical Storm Beryl will move slowly northwestward and then turn northward over portions of northeastern Florida and southeastern Georgia

on Monday and Monday night. Strong wind and rain will continue to effect these areas up through North Carolina as Beryl moves inland, while dangerous surf conditions, including rip currents, remain a concern along the coastal areas from northeastern Florida to North Carolina. Rainfall totals of 3 to 6 inches are expected from northern Florida through southeastern North Carolina from this system. For more information on Beryl, please visit http://www.wunderground.com/tropical.

Meanwhile, to the north, the deep storm in the Dakotas will lift northeastward across the Upper Mississippi Valley with scattered showers and thunderstorms. The cold front associated with this system will extend southwestward from the low through the Southern Plains. Showers and thunderstorms will form ahead of the front from the Central and Southern Plains into the Upper Great Lakes. There is a slight risk of severe storms from Wisconsin and Michigan southwestward across portions of eastern Iowa, northern Indiana, Illinois, and northeastern Missouri. While the main concerns with storms in these areas are damaging wind gusts and large hail, a few tornadoes may also become possible. To the south, areas of south-central Oklahoma into northwestern Texas may experience hail and damaging wind gusts. To the east of this system, an associated warm front will extend through the Northeast and will become nearly stationary. Moisture overrunning this front will aid in producing showers and thunderstorms from areas of the Lower Great Lakes into the Northeast. There is a slight risk of severe storms from upstate New York into Vermont and western Massachusetts with isolated hail events.

In the west, showers will continue across parts of the Northern Intermountain West and Northern Rockies, while a cold front brings cool, cloudy and chances of showers to the Pacific Northwest.
