Itappears that for about half the country, the local weather willunfortunatelynot cooperate for a view of tonight's big moon show. For cities suchLosAngeles, Chicago, Denver and Boston, the total lunar eclipse willlikely betotally eclipsed by clouds. On the other hand, New York, Philadelphia,Miami andDallas should enjoy mainly cloud-free conditions.

Duringtonight's lunar eclipse, theEarth will align betweenthe full moon and the sun, covering the lunar surface in shadow. Theeclipse isalso falling on the same day as the wintersolstice in the Northern Hemisphere ? a rare occurrence thathasn'thappened in 372 years. And to top it all off, the Ursidsmeteor shower is expected to create a few shooting starstonight thatshould be especially visible given the dimmed moon. [CompleteLunar Eclipse Guide]

Thatis,if the weather cooperates.

Stubbornlow clouds are expected to disappoint prospective eclipse watchersacross muchof the upper Midwest, lower Great Lakes, and parts of the South andnation's heartland. Light snows will fall from northern Indiana through theChicago area, thennorthwestward into much of Wisconsin, northern Minnesota and northeastNorthDakota.

Meanwhile,an active storm track from the Pacific Ocean is expected to bring awidespreadswath of clouds and precipitation across much of California, and partsof the intermountainregion and desert Southwest. Heavy rains will soak the Los Angelesarea, whileheavy snows are forecast for parts of southern and western Utah andover thePark and Sawatch Ranges of Colorado.

MuchofWashington State, western Oregon and northern Idaho will also likely berobbedof a view of the totally eclipsed moon, thanks to an offshore Pacificstormsystem.

Finally,central and northern New England will likely be plagued by cloud cover,theresult of an intensifying storm southeast of Nova Scotia. The stormwillbacklash this region with strong, gusty winds, considerable cloud coverandlight snows for northern Vermont, northern New Hampshire and much ofMaine.

Therestof the United States should be able to partake in at least some viewsoftonight's lunar eclipse.

Regionsthat are highly favored to have clear skies include the greater NewYork areaand points south down into the middle Atlantic Coast, as well as muchof Texasand southern and central Florida.
