Charleston Weather

Light rain coming through soon but it won’t be an effective pollen rinse I don’t think.

The Tornado Watch for Berkeley and Dorchester counties has been cancelled.

The risk for severe weather is all but over — the tornado watch is on track to expire at 1pm if it doesn’t get canceled sooner — but gusty winds and falling temperatures with some showers will characterize the rest of the afternoon.

Gusty winds 50-55 MPH will be possible from St. Stephen to parts of Moncks Corner as the line of storms gets through. Rain will miss Charleston proper to the north, but more light rain will move in this afternoon.

The Tornado Watch for Berkeley and Dorchester counties continues until 1 PM.

The Tornado Watch for Berkeley and Dorchester counties continues until 1 PM.

The tornado watch has expanded into Berkeley County as a strong line segment approaches I-95. The greatest risk for severe will be roughly Moncks Corner northward, including Lake Moultrie, Cross, and St. Stephen.

The Tornado Watch has been expanded into Berkeley County and continues for Dorchester County until 1 PM.

A broken line of showers and storms continues to push eastward, with a Tornado Watch in effect for Dorchester County and points west. Some evidence of rotation continues within the line, but the expectation remains it will weaken before CHS.

A well-organized line of thunderstorms will push eastward toward the area around mid-morning to lunchtime. There is a risk for some severe weather, including a brief tornado, generally along and west of I-95. Tornado Watch is up for Dorchester until 1PM. Berkeley and Charleston not in the watch.

Tornado Watch for Dorchester County until 1 PM.

Thursday: Cold front arrives with showers, a few thunderstorms After a new daily record high of 89° was set at the airport on Wednesday, changes are forthcoming as we head into Thursday as a cold front approaches the area. We will start the day quite warm — record warm low temperatures are not out of the question — with lows in the mid-60s at coolest. Temperatures will then head into the mid-70s before a band of showers and thunderstorms approaches the area by mid-morning.

After record warmth on Wednesday, a cold front moves through Thursday to restore order to temperatures that are more in tune with June than March. Watch for gusty showers and storms Thursday, followed by sunshine Friday and Saturday before another front on Sunday.

Highs today: 89° at the airport, breaking the record high of 85° last set in 2015; 78° downtown, missing the record of 82°. Very sharp temperature difference courtesy of the cool shelf waters of the Atlantic.

Yep, that is correct! May only excite the pollen producers though…

1PM: 88° again at the airport, shattering the record high of 85° set in 2015. Touching 90° doesn’t seem out of the question, either…

Rest of the work week: Record warmth expected Wednesday, then a front cools us off Another very warm day is on tap for Wednesday on the heels of the warmest day thus far in 2026. Wednesday's forecast high of 87°, if it verifies, would break the daily record high for March 11 of 85° set in 2015. We'll have plenty of sunshine for a good bit of the day, though cloud cover will tick up in the evening ahead of a cold front that will begin to restore a little order to a spring preview that's gotten a bit out of hand.

Another very warm day is on tap for Wednesday, which may yield a new high temperature record for March 11. A front comes through Thursday, and we cool back more toward mid-March normals for Friday.

Highs today: 88° at the airport, 84° downtown. Both missed record highs, but will still go down as the warmest day so far in 2026 at both climate sites.

We’re up to 88° as of 4PM, bringing the high within two degrees of the record of 90° set in 1974.

The Dense Fog Advisory for Berkeley County will expire at 10 AM.

Dense Fog Advisory for Berkeley County goes into effect today from 6 AM until 10 AM.

The week ahead: Warmth peaks mid-week, then a little cooler The stretch of abnormally warm, 80°+ days continues for the first half of the upcoming work week before a cold front knocks temperatures back a little bit as we head into the weekend.

A very spring-like radar this afternoon as a broken line of storms moves through inland areas. Heads up for strong winds and lightning along with heavy downpours.

At this time tomorrow, it won’t be this time tomorrow. Be sure to set your clocks forward tonight as DST returns!
