After tracking Cristobal for the last nine days, it has finally exited the United States north of Lake Superior as an extratropical storm. In its wake, gusty winds and showers remain across the upper Great Lakes, gale warnings are in effect for Lake Michigan and eastern Lake Superior. Meanwhile, a compact low pressure system along a sharp cold front is currently moving across Lake Michigan and will spread strong gusty winds and thunderstorms through the lower Great Lakes and Ohio Valley this afternoon and evening. Widespread severe winds, along with isolated tornadoes, are possible across eastern Michigan and much of Ohio. Weather conditions across the Great Lakes will gradually improve on Thursday as the entire storm complex ultimately moves farther away into eastern Canada. Behind the cold front, cooler and drier air along with clearing skies and diminishing winds will spread across the Plains through tonight. In contrast, very warm and humid air will stream all the way up the eastern U.S. well ahead of the aforementioned cold front. Much of the eastern U.S. and Southeast will see some form of showers and thunderstorms during the next couple of days before the front reaches the East Coast later on Thursday. Isolated instances of flash flooding will be possible on Thursday across southeast Virginia and eastern North Carolina, due to the slow moving nature of the thunderstorms along the stalling front. Showers and isolated thunderstorms will linger across the Mid-Atlantic southward into Florida into Friday as well. Temperature-wise, the widespread below average temperatures currently across the Plains will push eastward on Thursday, while moderating slightly. Meanwhile, the West will see a gradual warming trend as elevated fire weather threat continues over the Great Basin and south-central Plains. The Pacific Northwest will see an increasing chance of rain as a Pacific cyclone edges closer toward the region Thursday and Friday.
