Across about two-thirds of the United States will enjoy fair weather for today's rare transit of Mercury, but other regions will unfortunately be under clouds and rain as Mercury starts its march across the Sun's disk.

In the Eastern US, a storm will bring considerable cloud cover and wet weather, especially over the Northeast States. A frontal system with some clouds and scattered precipitation will be draped from the western Great Lakes and the Northern Plains; a small storm may evolve over Wyoming.  A Pacific disturbance will push clouds and wet weather into the Pacific Northwest. The rest of the country should enjoy basically fair and dry weather.

Here is a  specific weather breakdown for seven regions of the contiguous US:

NORTHEASTERN STATES

Little hope of getting a view of the transit from here. Mainly overcast skies with heavy rains extending from the New Jersey Coast and the Greater New York Area eastward through the New England Coast. Possibly a few sunny breaks "may" develop near the Middle Atlantic Coast.

GREAT LAKES AND THE MIDWEST

Any views of Mercury's tiny silhouette will be over southern sections. Mostly cloudy skies across Michigan with some rain over the Upper Peninsula.  Clouds also prevail Wisconsin, northern portions of Illinois and Indiana and eastern sections of Ohio and Kentucky. A broken to scattered layer of clouds, with some intervals of sunshine for western and central portions of Ohio and Kentucky and southern portions of Illinois and Indiana.   

SOUTHEASTERN STATES

Dicey visibility from the Tar Heel and Palmetto States. Mostly cloudy skies across western and central sections of North Carolina and much of South Carolina. A broken to scattered layer of clouds, with some intervals of sunshine possible along the coastline of the Carolinas. The rest of Southeast, down through the Deep South and Gulf Coast, including Florida will enjoy mostly sunny skies.

NORTH CENTRAL STATES

Mainly cloudy skies with some rain and showers for parts of Montana, Wyoming and Minnesota. Clouds will also prevail over Wyoming and the eastern half of Iowa.Farther south, sunshine should be plentiful over Colorado, Nebraska, Kansas, Missouri and western and central Iowa.

SOUTH CENTRAL STATES

This is the place to be to watch the transit: Wall to wall sunshine from New Mexico to Arkansas and Louisiana, including Oklahoma and Texas.

PACIFIC NORTHWEST STATES

Mostly cloudy with some rain and showers for Washington, and Idaho.

SOUTHWESTERN STATES

Clouds and showery weather for northern portions of California and Nevada. Sunny skies are expected elsewhere.

We should stress that these are only general outlooks.
