Jared Smith founded @chswx on Twitter in 2008 as an experiment in disseminating weather data through social media. In the ensuing decade-and-a-half, @chswx has provided live coverage of tropical cyclones, tornadoes, severe weather, and even a couple bouts of winter weather to the good people of Charleston, SC.
After today’s round of rain for many of us, we return to a drier and warmer pattern once more as low pressure slips out of the area. While isolated to scattered thunderstorms will be possible each afternoon, a good bit of us will remain dry. Highs will begin to head back up starting Saturday, with low-to-mid-80s expected across the area. On Sunday, highs look to peak closer to the upper 80s, and we’ll be flirting with 90° by Monday, as above-normal temperatures are expected heading into much of next week.
Coastal flooding will remain a concern with each high tide cycle through Saturday evening, and then with the evening high tide on Sunday as well. Minor to moderate coastal flooding looks to be probable, with road closures a consideration an hour or two each side of the predicted time of high tide. Expect Coastal Flood Advisories from the National Weather Service.
This weekend’s high tides:
Saturday: 6:55 AM (approaching minor flood), 7:33 PM (minor flood stage)
Sunday: 7:46 AM (currently predicted to stay below flood stage), 8:23 PM (minor to moderate flood)
Low pressure, which has brought some generally light showers to the area today, will continue to push southwestward across the area for Friday and the first part of the weekend. The best rain chances arrive tomorrow as the low makes its closest approach, but aside from some pockets of heavier rain, storm totals should generally run around a half-inch to 3/4” at best — certainly not the drought-buster we need. Temperatures will top out a little warmer in the upper 70s to around 80° as winds begin to turn more southerly as the low moves inland.
Scattered showers and a thunderstorm or two will continue to be possible heading into Saturday as the low meanders westward. Southerly flow around the low will continue to keep the heat pump running, though, and highs should top out in the mid-80s in the afternoon after we start in the mid-60s. While a shower or storm can’t be ruled out for Sunday, most should stay dry, and temperatures continue to nudge upward in the afternoon on the higher end of the mid-80s. By next Monday, we should be in the 90s again, so soak up the last of this cool air while you can!
After a rather gorgeous — if not a touch windy — stretch of weather across the Lowcountry, rain chances return to the forecast for Thursday afternoon and evening as coastal low pressure drifts closer to the area. We’ll start to see an increase in cloud cover overnight into tomorrow morning, but the best rain chances should hold off until the afternoon. We may be contending with some showers for the evening drive, so be alert to that possibility. Temperatures will still run on the cool side as breezy north and northeast winds continue across the area; with the cloud cover and approaching rainfall, we shouldn’t see highs much warmer than the mid-70s.
We’ve got one more really good weather day in store for Wednesday before low pressure drifts westward toward the coast, bringing in periods of showers and thunderstorms beginning Thursday afternoon and evening into Friday, leaving some scattered shower activity around for Saturday as well. We could definitely use the rain, and it doesn’t look like there will be any severe weather coming along for the ride, either — a win-win situation considering our worsening drought situation. (We could still see a few thunderstorms, though, and lightning makes every thunderstorm dangerous.)
Temperatures will remain below normal through Friday given continued northward winds and then rain-cooled air, especially as we get into Friday. Peeking ahead toward the weekend, though, we will begin to see temperatures rebound into the mid-to-upper 80s as winds go more southerly, with the 90s returning to the picture on Monday. Savor the cooler weather while we’ve got it, because we’ve got fewer and fewer days like this ahead until the fall.
After a highly unseasonably cool Mother’s Day, temperatures will remain generally pleasant over the next few days as high pressure runs the show. We’ll see a gradual warming trend into mid-week, with highs topping out near 80° by Wednesday. Lows, though, will continue to run well below normal in the low to mid-50s away from the coastline into Thursday. Skies should be more clear than we saw for much of today, too — keep the sunscreen applied if you’re out and about!
On Thursday, shower chances will begin to increase in the afternoon as moisture from an offshore low pressure system begins to kick up some as said low moves more westward. The best chance of rain will arrive Friday as the low moves across the area, with the potential for a few heavy downpours in there as well. (Fingers crossed, given the current drought situation!) Shower chances linger into the weekend as above-normal temperatures return. Sunday could once again approach 90° in some locations — ’tis the season.
Mother’s Day in the Lowcountry looks pretty outstanding, weather-wise, if not a touch chilly for this point in the year. A reinforcing cold front will come through overnight, helping to drop tomorrow morning’s lows to the mid-50s. Highs will only reach the low 70s despite mostly sunny skies as a trough lingers aloft. This is well below normal for this time of year — the normal high for May 8 is 82°!
We’ll continue this run of below-normal temperatures for a couple more days. Lows could bottom out in the upper 40s in spots on Monday morning before a warming trend begins. Even still, expect temperatures to run right at or just a touch below normal for much of next week. We have all summer to head back into the 90s each day, after all, so let’s get some more spring in while we still can.
A series of cold fronts will usher in a fairly refreshing airmass after our first 90° days of the year this past week. The first front gets through early tomorrow morning, helping to limit highs to around 80° Saturday afternoon under partly cloudy skies. Winds will be breezy, though, with gusts 30+ MPH possible at times, so be aware if you have outdoor plans or need to drive on the bridges.
A second front comes through overnight Saturday, which will make Sunday even cooler. We’ll start in the 50s and only get to the mid-70s in the afternoon with partly cloudy skies continuing. This is several degrees below normal for this point in May. We’ll keep below-normal temperatures well into next week, too.
One thing we won’t see? Rain. We could certainly use it, too, as moderate drought continues across the area. Our next rain chance arrives next Thursday, so keep watering until then.
A cold front will come through this weekend, bringing strong storms to the area Friday evening before restoring order to temperatures by Sunday.
After hitting 92° at the airport today, we’ll climb back into the 90s on Friday afternoon. Much of Friday looks to remain dry (though a stray shower or two can’t be ruled out in the morning). However, we’ll be watching a squall line and an associated risk for severe weather push eastward through the Carolinas during the day. Damaging winds and large hail would be the primary concerns, though a tornado can’t be ruled out. The best risk of severe weather will be along and west of I-95. The line will be getting into the Charleston metro area later in the evening, and as a result, we should begin to see some weakening as daytime heating is lost. However, sporadic wind damage or hail will still be possible as the line pushes offshore, so you’ll want to keep an eye out for rapidly changing conditions Friday night.
The cold front will get through the area Saturday morning, but a deep trough aloft will still allow for a slight chance of showers and thunderstorms in the afternoon. Temperatures will top out in the mid-80s, a far cry from where we’ve landed the last couple days.
Pleasant weather returns in full force for Sunday. High pressure will build in, and the cooler and drier airmass will yield highs in the upper 70s to around 80° under mostly sunny skies. If there’s a pick day for getting out and about this weekend, it’s Sunday.
From there, seasonable temperatures continue for much of the new work week, with highs in the upper 70s to low 80s continuing at least into mid-week, with dry weather looking to stay in place until Thursday. But let’s not trouble ourselves too much with a new work week with a weekend on tap, shall we?
Thursday looks to be the hottest day of 2022 thus far, with highs in the low 90s expected away from the coast. (It’ll be in the low to mid-80s at the beaches, making for a good getaway if you can get away with it.) Despite a cold front stalled nearby, expect a little too much dry air aloft to get much in the way of thunderstorm formation in the afternoon (though you can never totally, 100% rule out a stray storm in this kind of regime).
We stay hot heading into Friday, with another day touching 90° anticipated. We should see some more thunderstorms, though, especially as the front begins to work into the area in the afternoon and overnight into Saturday. The front will kick the summer-like weather out for a few days at least starting Sunday, with highs around 80° making for what looks to be quite a nice weather day to round out the weekend!
Our warm start to May continues for the rest of the work week as Atlantic high pressure and ridging aloft build across the area. We should see our first 90° reading of the year on Thursday. This comes a few weeks earlier than we saw 90° for the first time last year, but overall, we touch 90° in the first week of May more often than not. We stay warm on Friday as a cold front approaches from the west, perhaps getting close to 90° once again.
Isolated showers and thunderstorms will factor into the forecast each afternoon along and ahead of the seabreeze, with a pulse severe thunderstorm or two possible with damaging downburst winds and perhaps some large hail. Widespread severe weather is not expected, and I suspect that the best chances for a severe storm will be found where outflow boundaries and/or the seabreeze intersect, giving a little more oomph to thunderstorm updrafts.
We should see an uptick in shower and storm coverage on Friday afternoon and evening as a cold front gets a little closer; however, these storms will remain generally scattered. Keep an eye out for storms Friday evening and be ready to bring outdoor activities indoors quickly if lightning approaches. If you’re hearing thunder or seeing lightning strikes, you’re close enough to be struck!
The front will get into the area on Saturday with more scattered showers and thunderstorms. Cooler and drier air moves in Sunday, gradually scouring out precipitation and cloud cover while bringing temperatures back down closer to early May normals (low 80s).
