Cristobal has continued to traverse the central portion of the mainland U.S. and is approaching the upper Great Lakes early this morning. Cristobal is losing tropical characteristics but is still carrying heavy downpours and strong gusty winds. In fact, gale warnings are in effect for Lake Michigan and eastern Lake Superior. The post-tropical cyclone is forecast to intensify as it moves across the upper Great Lakes this morning before departing into Canada later today, bringing an end to the heavy rain. In the mean time, a compact low pressure system along a sharp cold front in the wake of Cristobal will spread strong gusty winds and some thunderstorms through the central Plains and upper Midwest today, and into the Great Lakes through tonight. Weather conditions across the Great Lakes will gradually improve on Thursday as the entire storm complex finally moves 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 cold front. Much of the eastern U.S. and down in the Deep South including the Southeast will see some form of showers and thunderstorms moving across during the next couple of days before the front reaches the East Coast later on Thursday. The front is then forecast to become nearly stationary, with showers and isolated thunderstorms lingering across the Mid-Atlantic southward into Florida later on Thursday into early Friday. Temperature-wise, the widespread below average temperatures currently across the Plains will push eastward behind the above mentioned strong cold front toward the eastern U.S. 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 through Friday morning.
