The Great American Solar Eclipse will take place August 21st, with the Miami Valley enjoying a partial eclipse with about 89% of the sun eclipsed.
The viewing will begin around 1 p.m. with the max eclipse around 2:28 p.m. This means plenty of people will be outside during the peak heating hours of the day.
Make sure you DO NOT look directly at the sun even for a few seconds unless you have ISO compliant solar eclipse glasses.
The day will warm up quickly with most of the eclipse time-frame in the mid to upper 80s. Dew points will be in the 60s so it will feel muggy as well.
Heat index values can reach the low 90s that day so please make sure you have plenty of water to stay hydrated and take breaks outside if you feel like you are overheating.
There will be a good deal of sunshine especially early but as the day goes on some high clouds and a few fair weather clouds look to develop. We are lucky that the forecast will stay dry to enjoy the show!
