It's been a long, hot summer. That might be an understatement, actually, as the U.S. experienced it's hottest summer on record! Areas like the Southwest were especially warm, but even through September the South and Southeast have been scorching!

Just in time for fall, a cold front will be cutting across the country to start the week, dropping highs from the 90s to the 60s in some areas! While it won't be completely dry behind the front, many people will feel a significant cool down.

Unfortunately, for folks along the Gulf Coast and down into Florida, this front won't be strong enough to reach that far south, but for areas like Oklahoma, Kentucky, and Virginia, this will usher in a major change!

Highs will drop 20-30 degrees in many areas from Sunday through Tuesday, including Oklahoma City and Washington D.C.!

Autumnal Equinox

Fall begins on Tuesday, at 8:04 pm ET, which is the exact time the suns rays cross over the equator the southern hemisphere begins to lean more toward the sun.

Both the vernal and autumnal equinox (Latin for equal night) marks the point of the year when the earth gets hit equally by the sun in both hemispheres. This is different from the winter and summer solstice, when the hemispheres reach their point of maximum inclination toward the sun.
