Super Flower Blood Moon weather forecast: What to expect in the US for the total lunar eclipse

A total eclipse of the moon will occur tonight (May 15) and if you’re looking for the best weather conditions the event, we suggest heading to the Northern and Central Great Plains where mainly clear skies will prevail through the entire celestial show.

Elsewhere around the country, the weather will be problematic in varying degrees for the lunar eclipse, which is the first of 2022 and is also known as the Super Flower Blood Moon of May. (That’s because it’s the Full Flower Moon and is happening while the moon is at its closest to the Earth or the month, making it a so-called supermoon.)

If you end up with bad weather, you can watch the Super Flower Blood Moon eclipse online and enjoy views of the full moon from around the world where the skies may be clearer. The eclipse will begin at 10:28 p.m. EDT (0228 GMT on May 16), reach its Blood Moon peak at 12:11 a.m. EDT (0411 GMT) on May 16 and then end at 1:55 a.m. EDT (0555 GMT).

Thanks to a cold front, the region that has the greatest chance of getting completely shut out of getting even a brief glimpse of tonight’s shady celestial drama on the moon will be around the Southern Great Lakes. That includes the big cities of Chicago and Detroit, and extending southwest within a band encompassing much of Indiana, the southern and eastern half of Illinois, southeast Missouri and much of the state of Arkansas. There’s also a slight risk of severe thunderstorms across this entire region as well. 

Along the heavily populated Atlantic Seaboard, from Maine south to the Florida Peninsula, the weather will be at the mercy of convective clouds and showers. 

Sunday afternoon sunshine will warm a humid and unstable atmosphere, creating a build-up of clouds, “pop-up” showers and thunderstorms. After sundown, the air will cool and the showers will diminish and end.  The cloudiness will slowly dissipate, but unfortunately perhaps not quickly enough to allow views of the eclipsing moon.  We’ll allow for the possibility of some occasional breaks for some locations; thus, not a complete shutout, but what could be categorized as fair-to-poor conditions.

Western states offer good lunar eclipse weather

Most places west of the Mississippi should be in good shape for eclipse watching with a few localized exceptions: western portions of Washington and Oregon where widespread low clouds will be prevalent. 

A narrow strip of overcast skies will be present over northern and western Idaho where there could be a few localized showers and thunderstorms, and an anomaly: partly to mostly cloudy skies over the normally cloud-free region of southwest Arizona and a slice of southeast California. Prospective eclipse watchers situated right along California’s Pacific Coast would be advised to head inland to avoid the marine layer which could spill ocean clouds from the ocean after dark. 

The moon could play hide-and-seek with a swath of mid-to-high level cloudiness over portions of the central and southern Rockies and northern Texas.

Finally, on a somewhat positive note, there could be a corridor of clear to partly cloudy skies extending south from western New York through the Ohio Valley.

Our weather map above 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. For a more detailed and localized outlook, we suggest checking the latest updated forecast from your local National Weather Service office. Here is link to the National Weather Service Organization page that lists all of the Weather Service Forecast Offices across the United States, including Alaska, Hawaii and the Pacific Region.  Just click on the office that serves your area to get not only the latest weather outlook, but access to local radar and satellite imagery as well.

If you’re clouded-out of tonight’s eclipse, you won’t have to wait long for a second chance. Our next opportunity to see another total lunar eclipse will come later this year during the morning hours of Nov. 8.

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