Temps nearly 20 degrees below average Wednesday morning

Posted: Updated:

Not so fast, Spring.

Old man winter has decided he's not finished quite yet.

After several nice Spring days, temperatures went for a nosedive Wednesday morning.

Temperatures are as cold as the upper 20s in parts of metro Atlanta.

How rare are 20s in late March?

The normal low for Wednesday morning is 46 degrees, which means Atlanta is about 20 degrees below average.

In addition, we typically see our last 20-degree temperature on March 9 -- over two weeks ago!

The last time it was this cold?

The last time Atlanta saw a 20-degree temperature this late in the season was in 2007 when it dropped to 28 degrees on April 7, according to Trisha Palmer at the National Weather Service.

Before that -- 2001 when it was 29 degrees on March 27.

And before that -- 1992 when it was 29 degrees on April 3.

As you can see, 20s in late March is not very common for Atlanta. Bundle up.

Freeze warning

A freeze warning is in effect from midnight until 9 a.m. Wednesday morning.

Freeze warnings this time of year are particularly important due to the increased likelihood of plants being damaged.

Some of the nice and warm days we have seen in March have allowed spring vegetation to develop.  Now that we're taking a nosedive back into the 20s, you'll end up with "warm weather" plants and other vegetation that most certainly won't be able to survive this cold snap.

Move sensitive plants indoors or cover them to protect them.  And, don't forget to bring pets indoors or provide a way for them to keep warm.
