IMPORTANT FORECAST UPDATE

IMPORTANT UPDATE FOR TOMORROW'S RAINFALL:

Well, here's what's going on: A shortwave over the Central Plains will move into the Western Great Lakes this evening and the overnight hours, bringing a chance for showers and thunderstorms. A str

ong and rapidly developing shortwave will drop south out of southern Canada, eventually phasing with the shortwave by tomorrow mid morning into the early afternoon. This will cause a jet streak to form, resulting in strong UVM (upward vertical motion) across the area, and the formation of rain bands. One of the reasons why I don't believe many thunderstorms will form is because of the fact that the warm, moist air mass gliding over the warm front will produce widespread clouds across the area by the morning hours. The front will intensify during the day, with the latest models suggesting the front will sit right over the area, which will make it very hard to forecast high temperatures. The low pressure system will develop along the front, turning it into an open wave cyclone. Showers and thunderstorms will form in response to the highly moist air mass moving into the region. In areas south of Route 6, there is the possibility that the atmosphere may destabilize by the afternoon, especially if the storm systems forms farther to the north. This could allow for an isolated severe storm, but at this time, it is not likely. Widespread showers and thunderstorms will likely continue into the late evening and possibly overnight hours before tapering off in the dry slot of the developing storm. A few showers and thunderstorms will persist across the area during the morning hours on Friday as the cold front slides through.

As for rainfall amounts, they will range from just over a half an inch mainly south of Fort Wayne, to possibly over two inches in isolated locations. This will be enough to help further ease drought conditions across the area.

As for temperatures, tomorrow's highs will range from the middle 70's to the lower 80's south of Route 6. Clouds will prevail for most of the day, with MAYBE a peak of sunshine in spots.

After a trough builds into the East in response to the storm system deepening the main trough, and allowing a seasonably cold air mass to reside across the area for the weekend, with highs in the lower 70's.
