SPOKANE, Wash.—People heading out to watch the eclipse on Monday might want to grab a jacket.

On Monday August 21, the moon will completely cover the disk of the sun in a line from Oregon to South Carolina.

Spokane will experience a 90 percent totality that day for up to two minutes.

People won’t just be seeing the eclipse, but feeling it too.

During the period of time when the sun is blocked out there will be a sudden drop in temperatures.

Temperatures could drop as much as 15 degrees during the solar eclipse.

Right before the solar eclipse, people will be standing or sitting in comfortable "mid-day" summer temperatures.

Then, the air will suddenly change, since the moon will block the sun's rays.

After the morning eclipse peaks around 10:30 a.m. air temperatures may feel more similar to what people would experience right after sunset.
