What happens if it's cloudy for the April 8 solar eclipse?

Though everyone is hoping for clear skies, here's what might happen if an eclipse-chaser's worst enemy β€” clouds β€” decides to make an appearance.

If you can't get to the path of totality for Monday's #TotalSolarEclipse, there will be a partial eclipse across North America. (graphic by Fred Espenak made before he retired from NASA) Do not look at the sun.😎 Even if you don't have eclipse glasses, either make an eclipse projector or find bits of sunlight in the shadow of a tree, which project images of the eclipse. #Eclipse2024 #astronomy
Wikipedia has a section of its solar eclipse article on viewing partial solar eclipses. Using a tree as a projector is fascinating and free. (images by Bree~commonswiki & Bhadrapriya BC on Wikipedia) https://en.wikipedia.org/wiki/Solar_eclipse#Partial_and_annular_eclipses #Eclipse2024 #astronomy

I have arrived in the path of totality for #SolarEclipse2024 in Mesquite, Texas. Now the #eclipse will come to me.
Already some fun as I was interviewed by Marcia Dunn, Aerospace writer at AP. #astronomy

I arrived for #SolarEclipse2024 around noon. All afternoon I've seen traffic slowing down, probably happening to some degree everywhere along Monday's path of totality. Highway signs in Texas say:

Solar eclipse Monday
delays possible
arrive early

"Weather is the hot topic as eclipse spectators stake out their spots in US, Mexico and Canada" by @AP - I was interviewed by Marcia Dunn of AP when I arrived in Mesquite TX. Here's her article. https://apnews.com/article/total-solar-eclipse-sun-moon-06767dd9e63cce8eb2351c22e90e38b1 #SolarEclipse2024 #astronomy
Total solar eclipse 2024: Spectators stake their spots along the totality path

Eclipse enthusiasts are staking out their spots across three countries, fervently hoping for clear skies. Forecasts are calling for clouds along most of the sun-vanishing route stretching from Mexico to the U.S. to Canada on Monday. North America won't see another coast-to-coast total solar eclipse for 21 years, prompting the weekend's worry and mad rush. Four minutes of daytime darkness beckon in Mesquite, Texas, where many locals are getting the day off. Others traveled thousands of miles to witness the cosmic event, if the weather allows.

Previously overcast skies are breaking to partly cloudy at Totality Dallas in Mesquite TX. Hoping for a view of totality over an hour from now. Partial #eclipse has begun here. #weather #SolarEclipse2024 #astronomy

Some reporting about total solar eclipses is a bit misleading. It's correct there won't be another total eclipse in Dallas for 300 years, or continental US for 20 years. But eclipses happen somewhere in the world every 6 months. #travel #SolarEclipse2024 #astronomy

Many used historical climate data to plan where to watch #SolarEclipse2024, since reservations would be gone months before #weather forecasts were in range. That's why so many went to Texas. Actual weather turned out backwards from expectations, better northeast. #astronomy
I heard from some people, and apparently this was a widespread problem, that their AirB&B reservations were cancelled by the hosts and re-listed for over $1000/night on other services. Some didn't find any new accommodations in the path of totality. #SolarEclipse2024 #astronomy

Looking Up and Down During the Eclipse

Astronauts and photographers captured unforgettable views of Earth and the Sun as the Moon’s shadow swept across North America.

I learned more about interaction of cloud cover and lowering temperature in an eclipse. Cumulus clouds that form from rising air lose energy and may clear in an eclipse, as happened in Mesquite TX for me in #SolarEclipse2024.
Mountains can cause stratus to form or worsen in eclipses. Clouds formed in both annular eclipses I attempted. In Reno NV 2012, Sierra Nevada mountain wave cloud formed. In 2023 north of Roseburg OR, it was overcast and then fog formed at the center. #astronomy #weather

Cloudy with a Chance of Eclipse

NASA citizen scientists collected thousands of photographs and temperature readings that are being used to study the relationship between total solar eclipses and clouds.  

A year ago I was on the way to see the Total #SolarEclipse2024. With snowfall expected to close I-84 in eastern Oregon's Blue Mountains, I had to leave a day early on the road trip to stay ahead of it. The snow followed just behind me until the Rocky Mountains in New Mexico where the storm weakened enough that a slightly late 9:30am departure allowed the sun to melt snow & ice on the pass on I-40. Overnight stops were in Boise ID, Price UT, Albuquerque NM and Wichita Falls TX. #astronomy #travel
One year ago was the day before the April 8, 2024 Total #SolarEclipse2024. I got to Mesquite, Texas (eastern Dallas metro) around mid-day to try to arrive ahead of the crush of traffic as everyone came from everywhere to the path of totality. Even before I found a place to get lunch, I met a news crew preparing to cover the next day's festivities in downtown. I was interviewed by AP aerospace reporter Marcia Dunn. https://spacey.space/@AstroHawk/112231193378607141 #astronomy #spacegeek #eclipse #travel

Marcia quoted me in her article, "I have arrived in the path of totality!" After the interview, we chatted about where we met before. I remembered her from 10 years earlier in 2014 at NASA's CRS-3 launch (SpaceX Falcon 9 & Cargo Dragon to ISS) where I had a "NASA Social" one-time social media pass and she was one of the pro media covering it. NASA TV showed us at adjacent seats asking questions in the post-launch news conference. https://spacey.space/@AstroHawk/112232761322006141 #astronomy #spacegeek #eclipse #travel

I also posted a similar quote online for the 2017 total solar eclipse, which I watched from Madras, Oregon. For viewing a total solar eclipse, it's a big deal to reach the path of totality. From that point, it's mostly up to the weather. But the eclipse will come to you once you're there. #astronomy #eclipse #travel
One year ago, April 8, 2024, was the total #SolarEclipse2024 across North America. I watched from the Totality Dallas festival in Mesquite, Texas.

One year ago... #weather is what you get. Forecasted storms were late, cleared just enough just in time to see #SolarEclipse2024 totality in Mesquite TX. Since cumulus clouds grow with daytime solar heating, the partial eclipse leading up to totality apparently cooled the air enough to inhibit them. Not everyone was as lucky that day. Spring is unpredictable - actual cloud cover along the path of totality differed from average expectations. https://spacey.space/@AstroHawk/112237121736018901 #eclipse #astronomy #travel

One year ago, the day after the April 8, 2024 total #SolarEclipse2024, I continued south from Dallas to Houston to see NASA Johnson Space Center, with a quick peek before the visitor center closed for the day. I returned for more there the next day. That day was the road trip's farthest point with dinner at the coast in Galveston. After that everything was on the journey back home. #spacegeek #travel
One year ago, April 10, 2024... 2 days after #SolarEclipse2024, I visited NASA Johnson Space Center in Houston.

A year ago on the return trip from #SolarEclipse2024, I posted a picture (which I took the previous day) of the Sierra Madera impact crater near Fort Stockton, Texas. The crater is 8mi/13km wide and US Hwy 385 goes through the middle of it. But the highway is the only spot you can see it since the rest of the crater is private property.

@AstroHawk Probably worth name checking Bob Dietz (of Arizona State, and elsewhere) as one of the key people in pushing to recognise lunar and earth craters as impacts, and not volcanism.

Crazy as it seems in retrospect, that was an idea many geologists were not happy about.

@BashStKid Don't worry. His name is known. Along with Shoemaker, he was "name checked" among the dedications for the 1998 book "Traces of Catastrophe" which still provides a relevant foundation for the science of recognition of impact craters. It's a free PDF download from Lunar & Planetary Institute. (In this case PDF means Portable Document Format, not Planar Deformation Features, which are a signature of impact shock found in rock crystals.) https://en.wikipedia.org/wiki/Traces_of_Catastrophe
