Beaver Moon eclipse weather forecast: Here's what to expect in the US for the nearly total lunar eclipse

Much of the Nation's midsection should be in fine position weatherwise, to get a view of the upcoming "almost" total lunar eclipse scheduled for late Thursday night/early Friday morning (Nov. 18-19). In contrast, sky conditions will be dicey along the Atlantic Seaboard, while across much of the Western U.S., the overall view looks rather muddled due to a rather extensive swath of cloudiness.

First, the good news: A large fair-weather dome of high pressure will be centered over southern Illinois early Friday morning and should bring mostly clear skies for eclipse watchers residing near the western Great Lakes, across the central Great Plains, Texas and Oklahoma, as well as most of the Deep South.

For those hoping to get a view of the predawn moon show along the East Coast, much is going to hinge on the strength and speed of a cold front that is expected to move through during Thursday night. The front will likely be accompanied by a band of clouds and showers, which obviously would obscure a view of the eclipse. However, there is a "chance" that drier air could sweep in behind the front accompanied by a gusty west-northwest wind. This might help to push lingering clouds out faster, or at least break up some of those clouds to afford some occasional views of the lunar show. 

If your weather cooperates, our guide on how to photograph a lunar eclipse, as well as how to photograph the moon with a camera in general, can help you make the most of the event. If you need imaging equipment, check out our best cameras for astrophotography and best lenses for astrophotography to help prepare for the next eclipse.

The farther inland from the coast you go, the better your chances of seeing the eclipsed moon (maximum eclipse is at 4:02 a.m. EST, when more than 97% of the moon's disk will lie inside the Earth's dark central shadow). 

Over the Southeast coastal region, cloudiness may interfere at times for the eastern Carolinas as well as for southeast Georgia. So far as the Florida Peninsula is concerned, it looks like clouds will unfortunately prevail for many, although — with guarded optimism — there's a possibility that northern Florida and the Panhandle area may see no worse than partial cloudiness.

Over the eastern Great Lakes and for parts of the northern Ohio Valley, an upper-level disturbance sweeping eastward, could generate partly to mostly cloudy skies.

Finally, for the Pacific Northwest, Rocky Mountain and Northern Plains states, two storms: one moving inland from the Pacific into northern California and the other over Colorado, will create a wide swath of considerably cloudy skies, which will probably hide much of the eclipse. Generally fair skies, however, are expected over central and southern California as well as southern Arizona and southern and eastern New Mexico.

Examine our map which shows the chances of clear skies for the eclipse, graded on a three-point scale: Good, Fair and Poor.

Of course, we stress that our National Outlook is only a generalization — a "broad-brush look" at sky conditions from coast to coast.

We wish one and all good luck, and clear skies!
