Here's the US weather forecast for the Super Flower Blood Moon

What will the weather in your area be for observing Wednesday morning's total lunar eclipse? Unfortunately, three unsettled weather systems will likely adversely impact sky conditions for prospective eclipse watchers over the central and western sections of the United States. 

A cold front draped from the Upper Peninsula of Michigan to the Panhandle of Texas will produce a broad swath of clouds, showers and a few strong thunderstorms from the central and eastern Great Lakes, the Ohio Valley and the southwestward down through the central and southern Plains. The heaviest rains are expected to fall over the Lower Peninsula of Michigan, Illinois and central Oklahoma.

Meanwhile, a storm over central Wyoming will serve as a "meteorological swizzle-stick" and mix up a wide variety of weather with everything from showers and scattered thunderstorms over the easternmost section of Washington state, as well as Idaho and western sections of Montana and Wyoming. Over the highest terrain of central Idaho, as well as Montana and Wyoming there is even a chance of wet snow! The associated cold front will be responsible for cloudiness over much of Colorado, Utah, New Mexico, Arizona and southern California.

Finally, a new cold front approaching the Pacific coast will spread cloudiness inland across western Washington, Oregon and northern California. 

Across parts of the Middle Atlantic and Southeast U.S., scattered-to-broken clouds, caused by increasing moisture could hinder views of the opening stages of the lunar eclipse before the moon sets. In those places specifically not mentioned, sky conditions should be good-to-excellent. Refer to our map to get a better idea as to where the best views may be obtained.
