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.
