About 70 percent of the country will be able to get a good view of the total lunar eclipse tonight (Sept. 27). Unfortunately for many who live east of the Mississippi River, the odds of seeing the moon as it passes completely into the Earth’s shadow are rather poor, according to current weather projections.
Read on below to get our supermoon lunar eclipse weather forecast for skywatchers across the United States. If clouds or bad weather ruins your view, don’t fret. You can always watch the lunar eclipse online in a webcast by the Slooh Community Observatory .

Unsettled for much of Eastern U.S.
At eclipse time, a low pressure system will be located just to the east of the Georgia coast. The storm is forecast to produce scattered showers and possibly a few thunderstorms across parts of the Carolinas, and spotty light rain for Virginia and West Virginia, Maryland, western Pennsylvania and eastern Ohio.
A second low pressure system over the western Gulf of Mexico is forecast to bring a swath of heavier showers and thunderstorms to parts of southeast Texas, as well as portions of the Deep South, Piedmont and Florida. Accompanying this precipitation will be widespread cloud cover extending from the Gulf Coast and Florida, north to the central and eastern Great Lakes.

Another area of unsettled and wet weather will be over the “Arrowhead” Region of northeast Minnesota, generated by an approaching cold front.

Alaska and Hawaii
And I haven’t forgotten you folks in Alaska and Hawaii. Unfortunately, Alaska will be almost completely clouded over along with areas of rain and showers. Hawaii will not fare much better for those hoping to catch the closing stages of the eclipse. Strong trade winds will keep most showers focused over windward slopes, with showers reaching leeward sides of the smaller islands over the next couple of days. Tropical storm Niala is forecast to pass south of the Big Island Sunday and Monday, and bring heavy rain to the Big Island and surf to east facing shores.
Central and West should get a good look; New England too
In contrast, most of the central and western United States, as well as New England and eastern New York State is expected to get a fine view of tonight’s total lunar eclipse . A frontal boundary situated over the central Plains and Rocky Mountains could generate some partial cloud cover but not enough to seriously hinder viewing of the eclipse. The Southwest Desert, Pacific Northwest and Californiawill be dry and tranquil … and perfect for viewing the moon show.

Over New England and much of adjacent eastern New York State, the weather will be dominated by a large fair-weather ridge of high pressure centered near Nova Scotia and stretching back to the west into the Northeast U.S. Few or no clouds should be the rule for northern and central New England providing near perfect weather for the lunar eclipse. Over southern New England and eastern New York, some high-to-mid level cloudiness might occasionally drift on by. But these clouds for the most part are not opaque, so the moon might still be visible even when clouds are passing in front of it.
In short, if you live in the Northeast U.S., the farther north and east you go, the better your viewing chances; farther to the west and south, thicker clouds are increasingly more likely to eclipse the eclipse.
