Weekend forecast: Cloudy and warm, with some St. Patrick’s showers

/ March 15, 2024 at 10:43 PM

The weekend won’t be the sunniest, but it’ll still be on the warm side for a couple more days before a Sunday night cold front resets the needle a bit on this recent period of warmth.

We narrowly missed a record high on Friday; it was 86° at the airport, with the record of 87° set in 1967 getting a little nervous this afternoon. It won’t be quite as warm on Saturday with more in the way of cloud cover as a front lingers nearby, but we should still make it to the low 80s in the afternoon with a mix of clouds and sun. Showers look unlikely at this juncture as we sit in a lull between disturbances.

We’ll get St. Patrick’s morning in generally on the dry side (and a touch cooler too with lows in the upper 50s vs. Saturday’s low 60s), but showers should begin to increase by afternoon as the aforementioned cold front gets closer. By evening, expect a fair bit of shower activity to overspread the area. This should last into the overnight before tapering off by Monday morning, which will kick off a week of weather featuring temperatures much closer to mid-March norms.

Friday & the weekend: Bits of unsettled weather, but plenty of rain-free time, too

/ March 14, 2024 at 9:28 PM

High pressure will lose its grip on the area for Friday and the weekend, allowing some periods of unsettled weather to move in — but don’t fret as we’ll have plenty of rain-free time as well. It’ll stay quite warm, too, with 80s expected each afternoon.

We’ll at least get Friday morning in rain-free ahead of a disturbance that’ll push a cold front into the area Friday afternoon and evening. Showers and a few thunderstorms will be possible by mid-afternoon leading into the commute, but not before we warm back into the 80s once again. A strong storm may not be totally out of the question west of 17-A, but high-res guidance generally shows storms in a weakening trend as they push eastward toward much cooler shelf waters.

Shower and thunderstorm chances persist overnight Friday into Saturday morning before what looks like a break in the action for much of the day. Temperatures start quite mild — think low to mid-60s — and warm back to the low 80s in the afternoon under a mix of sun and clouds. Shower chances should hold off Saturday night and into a good bit of Sunday before returning later in the afternoon and into the evening as another front approaches the area. This front shakes us out of our run of 80s and back below normal for Monday and Tuesday of next week.

Picture-perfect Thursday, but an unsettled weekend at times

/ March 13, 2024 at 9:11 PM

Thursday looks like an excellent weather day across the Lowcountry, something out of the late-April playbook but in mid-March. We’ll start the day around 50° once again, warming to the low 80s in the afternoon with maybe a few clouds amongst otherwise clear skies as ridging aloft strengthens briefly for the day. Expect winds generally in the 5-10 MPH range, picking up a little in the afternoon in the wake of a sea breeze. Enjoy!

Rest of the work week: Late April warmth in mid-March

/ March 12, 2024 at 9:54 PM

The rest of the work week will be much warmer than mid-March normals as high pressure ridges across the area at the surface and aloft. Temperatures on Wednesday will start in the upper 40s, warming to near 80° in the afternoon under partly cloudy skies as a weak disturbance ripples across the area, bringing only an uptick in cloud cover and little else given such a dry atmosphere at the surface. Thursday will see us solidly back in the 80s once again with just a cloud or two at times as high pressure will be strongest that day. We’ll start to see cloud cover come back up for Friday as high pressure gets shunted offshore by the next storm system, though it’ll still be a very warm day by mid-March standards as lows bottom out in the mid-50s with highs warming to the low 80s in the afternoon. We should get much of the day in rain-free, though a shower or two will be possible as we get into the late afternoon and evening hours.

Tuesday’s forecast: Getting springier

/ March 11, 2024 at 7:44 PM

After one more somewhat chilly night — expect low 40s across much of the metro, with mid-to-upper 30s possible further inland — we start a warming trend that’ll get us into the 80s by the end of the week. Tuesday looks rather delightful: expect highs to top out in the low 70s away from the locally cooler coastline. Comfortably dry air will be in place with relative humidity bottoming out around 30% in the afternoon, and we’ll keep a solid amount of sunshine throughout the day. Winds will start to swing more southwesterly in the afternoon and kick up to around 5-10 MPH. Not bad!

The week ahead: Mostly quiet and turning unseasonably warm

/ March 10, 2024 at 9:49 PM

The week ahead will be largely marked by high pressure before the next storm system starts to affect the area just in time for St. Patrick’s weekend. (Sorry.)

Sunday: A nice day ahead

/ March 9, 2024 at 8:43 PM

After the cold front that helped instigate quite a busy morning of weather gets offshore, we end up with a rather nice Sunday as cloud cover clears out, leaving mostly sunny skies in its wake. Temperatures will start in the low 50s and warm to the upper 60s to around 70° in the afternoon. The only fly in the ointment will be the breeze: expect gusty conditions throughout the day as high pressure builds in, with winds 10-15 MPH perhaps gusting to 25-30 MPH at times.

Saturday’s forecast: An unsettled day with the potential for strong thunderstorms and flooding

/ March 8, 2024 at 7:34 PM

After one round of thunderstorms moved through Wednesday, a second round of unsettled weather, featuring potentially flooding rains in the morning and severe thunderstorms in the afternoon, lies ahead on Saturday.

The week ahead: Periodically unsettled and warm

/ March 3, 2024 at 9:13 PM

Well, it will certainly feel like climatological spring this week as we stay on the warm side of normal for early March with a couple storm systems dropping through at times. First, though, we’ll get off to another potentially foggy start Monday morning as lows dip to the mid-50s. Fog should dissipate by mid-morning, and we’re looking at another warm day in the mid-70s under a mix of sun and clouds as high pressure asserts itself a bit more.

Sunday’s forecast: More warmth, some fog, and maybe some showers

/ March 2, 2024 at 10:04 PM

Clouds will continue to hang around on Sunday with the specter of a shower or two remaining in the forecast. We’ll likely start the day with patches of potentially dense fog at times, so be ready for low visibility in the morning. The fog’s expected to mix out shortly after daybreak, leaving behind generally overcast to mostly cloudy skies for the remainder of the day. It’ll be a warm start, with temperatures in the upper 50s yielding to highs in the low 70s in the afternoon. As mentioned, a few showers are possible, but it’s quite possible that much of us get the day in rain-free. Still not a terrible idea to keep rain gear handy, though, just in case.
