WEATHER ALERT: Coldest air since last winter headed for the Lowcountry

Storm Team 2

CHARLESTON, SC (WCBD) – Rain will develop across the Lowcountry Tuesday afternoon with rapidly falling temperatures expected later in the day.

“Many of us will be near 70 around the middle part of the day but will fall as much as 20-25 degrees, into the 40s, by sunset,” said Storm Team 2 Meteorologist Josh Marthers. “Rain and a gusty north breeze will make it feel even colder.”

After the rain moves off of the coast, the sky will clear and temperatures will continue to fall overnight.

“Most areas will drop to near or below freezing by sunrise Wednesday,” added Marthers. “This will likely bring an end to the growing season across the Lowcountry.”

Remember to protect sensitive plants and be sure pets have warm shelter from this early season cold snap.

MOUNT PLEASANT, S.C. (WCBD) – Bitterly cold temperatures will be settling into the Lowcountry on Tuesday. Wake-up temperatures on Wednesday morning will be in the 30s but feeling like the teens and 20s.

A freeze watch is in place for much of the area, but what does that mean? Storm Team 2’s Arielle Whooley has a look at some terms you might hear as the thermometer drops.

Freeze Watch: Issued when conditions are favorable for widespread freezing temperatures within the next 24-36 hours. This watch is only issued until the growing season has come to an end, which is marked by the first widespread freeze. A freeze watch can also be issued during the spring at the start of a new growing season. 

Freezing Warning: A watch will be upgraded to a warning when confidence has grown that a widespread freeze is expected. Just like the watch, this will only be issued during the growing season in the fall or spring when damage is possible to new plants or crops. 

Frost Advisory: This is issued when frost is likely during the growing season. Temperatures need to fall below the dew point, normally between 33-36 degrees. Frost will form on clear and calm nights. Frost is something that can be seen and likely forms on cars and grass. 

Make sure to move plants and pets inside, no one wants to be out with temperatures dropping below freezing.
