Thursday will be much cooler but still quite breezy as high pressure builds in behind a cold front. Expect highs to only peak in the low 60s despite sunny skies. We warm up for Friday and especially Saturday before another front stalls nearby Sunday, bringing cooler air and rain.

Visible satellite (and a peek out the window) shows we are dry-slotted, with mostly clear skies ongoing. The cold front itself is still to our west, and should clear later tonight. Gusty winds continue; still gusting to around 30 MPH at the airport.

The tornado watch will be allowed to expire on time at 1PM. We are still dealing with some gusty showers in eastern Berkeley and Charleston, but the severe weather threat is over.

The Tornado Watch for Berkeley, Charleston, and Dorchester counties will expire at 1 PM.

The main event of showers and thunderstorms is ongoing now, and the good news is that, so far, we don’t have any weather warnings. Heavy rain, gusty winds, and lightning remain concerns, and the tornado watch does continue for now, but we should be in good shape after 1PM.

Heavy rain is moving northeast across the Tri-County area ahead of an increasingly disorganized line of showers. It’ll stay breezy, and gusts over 50 MPH become possible with showers and storms moving through.

Getting close to 10am and we see the line reaching I-95 with some showers ahead of it. Winds continue to whip, with a 44 MPH gust recently recorded at the airport. Tornado Watch continues.

A few storms are firing ahead of the line near I-95. The line itself isn’t looking terribly impressive on radar right now, but that could change quickly. Stay alert: the Tornado Watch continues.

Non-thunderstorm winds are starting to rip: 43 MPH gust at the airport as of 8:39am according to NWS.

Severe Thunderstorm Warnings are once again beginning to blossom ahead of the line as it moves eastward roughly around 35-40 MPH. A couple more hours to go in the metro, methinks, before we are dealing with this. Tornado Watch is out; stay alert!

We’re dealing with some showers this morning ahead of the main line, which is moving through Augusta now. Expect winds to pick up over the next couple hours ahead of the line, which appears timed for the mid-morning through early afternoon hours.

Before you head to bed, make sure your loose items outdoors are safely inside or secured, just in case. Even if you don’t get a severe thunderstorm, it’s going to be plenty windy!

Tomorrow’s squall line stretches from northeastern MS down into New Orleans, with severe thunderstorm and even tornado warnings along it. A few showers continue to sprinkle on us here in the Lowcountry.

A windy Wednesday lies ahead as a strong cold front moves through. Gusts 40-50 MPH will be possible outside of thunderstorms, with even higher gusts within a squall line that'll come through the Tri-County generally after 8am. Can't rule out an isolated tornado within the line, too. Details:

The severe weather risk for Wednesday has ticked up as overnight guidance is now pointing to more available instability. The window for severe weather will be roughly sunrise to noon, primarily focused around a prefrontal line of showers and thunderstorms. More this evening…

It'll be warmer but cloudier on Tuesday as temperatures rebound a bit ahead of Wednesday's cold front. A few showers can't be ruled out, either, but the main rain chance comes along with the front on Wednesday. (A few strong storms might tag along, too.)

March will be doing March things this week as we go from frost and freeze on Monday morning to thunderstorms on Wednesday, with temperatures headed up and down the rollercoaster ride along the way.

Bring in your plants and pets tonight as frost and freeze will be an issue; A Frost Advisory is up for Charleston County, with a Freeze Warning for Berkeley and Dorchester. (Frost and freeze alerts are back with the resumption of the growing season March 1.)

Statewide burning ban now in effect. According to the SC Forestry Commission, 92 wildfires have ignited across the state today, with many of them in the Pee Dee region. It looks like wildfire conditions will remain favorable into tomorrow.

A Red Flag Warning goes into effect at 11am for inland Berkeley and Dorchester as winds and dry fuels combine for significant fire danger. Elsewhere, the risk is a touch lower, but I’d just hold off on burning everywhere for the next couple days to be safe.

March (and climatological spring) gets off to a warm start on Saturday as highs peak in the mid-70s. A front will come through overnight Saturday, and Sunday will be some 20° cooler as a result. No rain expected, but fire danger continues.

Temperatures tumble about 10° on Friday, but will still be comfortable with highs in the upper 60s. We warm back up for Saturday before cooling off even more sharply for Sunday, all with a good bit of sun in the mix. Watch for elevated fire danger Saturday and possibly Sunday, though.

Showers and even a few thunderstorms ahead of a cold front continue to push into the area this evening, especialy for those of you in northern Berkeley and Dorchester. Remains to be seen if these survive to the coast. Not everyone sees rain, unfortunately.

A front approaching the area could bring some rain to a few of y’all later tonight. Even seeing some lightning between Barnwell and Augusta. Won’t be a drought-buster, and we’ll stay dry heading into the weekend.

Clouds will increase ahead of a cold front on Thursday, which could bring a few showers to the area for later in the evening through overnight. Thursday's mid-70s cool off to the upper 60s to around 70° behind the front for Friday. After a brief warmup Saturday, we cool down even more Sunday.

Springlike weather continues for the rest of the work week, particularly through Thursday as temperatures head to the mid-to-upper 70s. We'll cool off a bit on Friday, but nothing too chilly, either, as we head toward what should be a quiet weekend of weather.

A much warmer and sunnier day is on tap for Tuesday as temperatures soar into the mid-70s in the afternoon. We'll keep this going Wednesday before clouds tick up Thursday ahead of a front that'll cool us off on Friday.

After a cloudy and cool Monday, we return to the 70s and sunshine to close out climatological winter with the primary shower chance Thursday night into early Friday as a cold front moves by, cooling us off a touch but still ushering in what looks like a nice weekend.

We'll see more sunshine tomorrow, but that shouldn't stop us from potentially setting a new record cold high temperature after a frigid start featuring wind chills in the teens. It won't last long, though, as a warmup will ensue over the weekend.

A chilly day awaits on Thursday as clouds depart behind the storm system that brought us today's chilly rain. We turn even colder Friday before warming back up over the weekend. Back in the 70s by the middle of next week!

Some light showers/drizzle continue as the atmosphere begins to dry out. There remains an outside shot at some freezing drizzle on elevated surfaces in far northern Berkeley and Dorchester tonight, but no impacts are expected.

A wet Wednesday lies ahead as a storm system affects the area with some much-needed rain, particularly in the afternoon and evening hours. From there, we turn much cooler, with temperatures as cold as we've seen since we had snow on the ground in January. We'll warm up this weekend, though.

Cooler-than-normal temperatures return to the area for the third week of February, especially in the second half of the week after a cold front comes through on Wednesday with widespread rain.

The Severe Thunderstorm Watch for Berkeley, Charleston, and Dorchester counties has been cancelled.

Gusts 40-50 MPH will be possible with the line of showers and thunderstorms as it progresses eastward across the area this morning. Sporadic wind damage remains a possibility.

Severe Thunderstorm Warnings stretch from the NC/VA border to the Gulf Coast as a line of windy showers and thunderstorms presses eastward. It’s crossing 95 now and should clear by midday. Severe Thunderstorm Watch in effect.

Sunday: Showers and wind, with sporadic damaging gusts possible Sunday will be a very breezy day as a highly dynamic storm system moves across the eastern half of the continental United States. Showers and a few thunderstorms should set up in a line ahead of a cold front which will come through…

Much cooler and sunnier weather is on tap for Friday, breaking this stretch of a few dreary days that has characterized the second half of the week. It'll be short-lived, though, with shower chances returning Saturday and especially Sunday with another front moving by.

Showers and maybe a thunderstorm are advancing eastward across the area. Brief heavy rain is possible for a few of you in the strongest storms. Keep rain gear handy!

The Dense Fog Advisory for Dorchester and Inland Berkeley counties will expire at 3 AM.
