A monster cold wave brought drastic changes to the Plains and Rockies already this week, but the cold will shift farther east this weekend.
Twitter was busy Friday morning with countless first snow pictures from the central part of the country, including the Denver metro area.
The cold wave fueling the snow across the Plains and Rockies will spread south and east through the weekend.
By Saturday night, the cold front initiating the cold wave will move off the East Coast as a much colder night advances into the Ohio Valley to the Appalachians.
For Chicago and Indianapolis along with surrounding areas, Saturday night will be the coldest since April.
"Normally, a freeze in early October in the Ohio Valley would cause problems with major agriculture, but they are nearly a month ahead of schedule because of the warm spring and hot summer," said Expert Senior Meteorologist and Agricultural Expert Dale Mohler.
"However, the cold wave will signal an end to the growing season for backyard gardeners," added Mohler.
Any remaining vegetables in gardens should be plucked off before the killing cold moves in.
While lows will gradually rise across the Plains Sunday night, the expanse of the cold weather will be at its greatest breadth.
Lows will tumble into the 30s from the Texas Panhandle, east into Tennessee and Virginia.
Cities such as Amarillo, Texas, to Springfield, Mo., and Nashville will tumble into the 30s Sunday night, all well below average for this time of the year.
It will be cold enough across the Northeast to support some of the first snow of the season Sunday into Sunday night.
Temperatures will rise to more seasonable levels next week for most, but areas from the northern Plains to the Great Lakes and Northeast will see repeated rounds of cold, bone-chilling air. An active northern branch of the jet stream will contribute to the repeated rounds of cold.
The cause of the mudslide is believed to be due to the drought conditions which have left Mt. Shasta’s glaciers exposed to the sun’s heat.
A pattern change will usher in cooler air and rain to the Northwest this week.
Autumn officially starts at 10:29 p.m. EDT on Monday, but it will not feel like autumn in some parts of the U.S.
Fung-wong will spread heavy rainfall across Eastern China, South Korea and Japan this week.
The peak of hurricane season, among other things, arrives in the fall.
A brief warmup is in store for residents of the Northeast this weekend before more fall-like conditions return.
