We should get much of, if not all of, Tuesday in rain-free before the pattern changes to something more unsettled to finish up the work week. We start Tuesday in the mid-50s; cloud cover and continued northeast flow will inhibit temperatures from rising much higher than the mid-70s in the afternoon. Some of the higher-resolution guidance has some isolated to scattered showers breaking out later in the afternoon into the evening hours as high pressure loses its grip on the area, but not everyone will see rain.
Quiet weather continues through the end of the work week. Wednesday will run quite a bit warmer than the past couple days as stacked high pressure settles in right over the Carolinas. Surface high pressure will slip into the Atlantic during the day Wednesday, turning winds a little more southerly and allowing temperatures to rise well into the mid-80s. The aforementioned high pressure will keep cloud cover to an absolute minimum, much like we saw on Tuesday.
Tuesday will be one of those meteorologically brilliant days that will undoubtedly make all of us wish it was the weekend instead. We start the day in fairly crisp fashion with lows bottoming out in the upper 40s to around 50°. High pressure will sit atop the area, and this combined with a very dry airmass will keep the sky unmarred by cloud cover. Temperatures will respond nicely, warming about 30° to the low 80s in the afternoon. Winds will be a little lighter, starting out of the north and swinging around to the northwest, west, and finally south by sunset.
Tuesday will be one of the better weather days we’ve had in a while around here, just an all-around gorgeous spring day. We’ll start the day in the mid-to-upper 40s and warm nicely into the low 70s in the afternoon under sunny skies. Dewpoints around 40° will yield a really comfortable day, too — not too dry, not too humid. Yes, it’s a workday, but with some of y’all on spring break, I hope you get to take advantage of this! Before you know it, we’ll be sweating buckets by merely stepping outdoors.
Above-normal temperatures will continue through Friday before a cold front stalls out to our south. Wednesday will feature another partly cloudy day with highs running in the mid-80s once again as ridging takes hold aloft. The ridge will begin to slip a little and clouds will increase ahead of the next storm system on Thursday. Despite the increasing cloud cover, we’ll have one more day of highs in the mid-80s.
We start quite warm once again (mid-60s) on Friday before scattered showers and maybe a thunderstorm or two advance into the area ahead of a cold front later in the day. The frontal passage is looking a little later now, so we should still see highs approach 80°. The front will then stall to our south and high pressure will wedge into the area, leading to a much cooler and wetter weekend in which highs will likely not get out of the 60s.
Lingering showers will clear the area overnight, setting us up for a much warmer Tuesday as winds go more westerly and clouds scour out. Expect highs to peak in the mid-80s away from the coast in the afternoon after starting the day in the mid-60s. These temperatures easily run 10°+ above normal for this point in the year, where the normal high is 74° and the normal low is 52°. (The record high for April 4 of 91°, set in 1963, mercifully remains safe.)
The final few days of March 2023 will be generally quiet, weather-wise (at least here in the Lowcountry), as a cold front moves across the area overnight and ushers in a cooler, drier airmass. Wednesday will be much cooler than recent days with highs peaking in the mid-60s. We’ll see a mix of sun and clouds throughout the day as a little lingering low-level moisture hangs around, but that’s about it.
The aforementioned moisture strips out later Wednesday, yielding a brilliantly sunny sky on Thursday. We’ll get off to a chilly start thanks to calm winds and clear skies from the night before with lows in the mid-40s (far from frost or freeze concerns, thankfully). Highs will reach the low 70s. All in all, not a bad day to get outside and take a walk.
Winds go around to the south beginning Thursday and this will yield a warmer Friday. Expect temperatures to peek in the upper 70s under partly cloudy skies. The 18z runs of the models indicate the potential for some showers coming ashore Friday afternoon; we’ll keep an eye on this, but for now, the going forecast is for mostly dry weather as some of you head out to pick up your Bridge Run packets.
Freeze Warnings will become a distant memory by the end of the work week as we warm rapidly into the 80s by Thursday.
Temperatures moderate nicely into the upper 40s Wednesday morning with highs topping out in the low 70s. A coastal trough moving inland might spread a few showers around, but rain amounts should be generally light and most of us should get the day in rain-free.
From there, things get a lot warmer. Thursday starts ~10° warmer than Wednesday did, with lows not dropping far below 60°. Highs soar into the low 80s under mostly sunny skies, with just a few passing clouds from time to time. Friday is largely a copy-and-paste from Thursday, just with slightly warmer temperatures expected. We look to stay in the 80s through the weekend and into early next week.
Welcome to Spring! A Freeze Warning is in effect for inland Berkeley and Dorchester overnight into Tuesday morning, with a risk for patchy frost in other sheltered spots. This will be the last one of these for a little while, though, as a warming trend commences. It will be subtle on Tuesday, with highs running in the mid-60s as opposed to the low 60s — still well below climatology for this point in March. Skies will generally run mostly sunny with a few more clouds in the afternoon.
Northeasterly winds and the new moon will combine to produce tidal flooding during the Tuesday morning commute. Water levels could approach 7.3-7.5′ around 8:34am, which should be enough to close a couple roads in downtown Charleston. Be ready for delays if downtown is in your plans, particularly the west side of the peninsula.
