Weather Underground Forecast for Thursday, June 14, 2012.
Drier and pleasant weather conditions with near normal temperatures return to the Northeast and the Mid-Atlantic on Thursday as the northern half of the cold front over the Eastern Seaboard exits the East Coast and moves into the Atlantic Ocean. The southern portion of this front will linger in the Southeast, creating chances of showers and thunderstorms along the central Gulf Coast.
Meanwhile, to the West, the system in the West will advance into the Plains Wednesday night and Thursday morning, bringing rain and thunderstorms to areas from the Upper Mississippi Valley and Upper Great Lakes through the Southern Plains. There is a slight risk of severe weather development from the Upper Mississippi Valley and the western Great Lakes into eastern Nebraska by the afternoon. While the main concerns with these storms will be damaging wind gusts and hail events, isolated tornadoes will become possible during the afternoon and evening.
Further West, onshore flow will maintain chances of light rain in northern Washington. Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 30 degrees at Grayling, Mich. to a high of 104 degrees at Needles, Calif.
