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.
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).
After Monday became the warmest day so far in 2022 with a high of 87°, Tuesday should come right back and at least match that with another round of warm and muggy weather. We’ll start the day in the mid-to-upper 60s away from the coast. (I wouldn’t be surprised to see temperatures not get below 70° in some spots at the beaches.) Temperatures will warm to the mid-80s under partly cloudy skies ahead of the seabreeze.
With high pressure still in play across the Lowcountry, afternoon shower and storm chances in the Charleston metro should stay at a minimum, but won’t be zero (as Daniel Island found out today with an absolute gullywasher). There will be a better chance of rain along and inland of I-95 where storms will have an easier time getting going thanks to surface temperatures approaching 90°. These storms should fall apart, though, as they move eastward toward the coast in the evening as sinking and cooler air behind the seabreeze circulation will help tamp out convection.
We continue to get warmer as the week goes on, with Thursday looking quite probably like our first 90° day of the year. A cold front could make Friday and the weekend a little unsettled, but will also restore some order to temperatures, bringing them back to early May norms by the end of the weekend.
The first week of May will serve as a preview of what’s to come as we edge closer and closer to summertime. The mornings will become increasingly muggy with lows bottoming out in the mid-60s on Monday and getting warmer as the week goes on. Highs for much of the week will run in the upper 80s; dewpoints in the upper 60s will make the afternoons feel more like the low 90s. We’ll even see that standard afternoon slight chance of thunderstorms that we know and love in the warm season Monday-Wednesday.
As we head into Friday and the weekend, a storm system will push a stalled cold front into and eventually through the area, elevating our chance of scattered showers and thunderstorms for Friday and Saturday. By Sunday, expect the front to be through, cooling us off a little with highs in the low 80s expected, making for what should be a nice Mother’s Day with just a slight chance of a shower or storm in the afternoon.
We’ve got another pretty good-looking weekend coming up. It won’t be quite as clear or as dry as last weekend, but it’ll still more than get the job done as temperatures rise through the 80s throughout the weekend. If sunshine’s your thing, suspect Saturday is going to be a little more in your favor as deep-layered high pressure hangs on for one more day, keeping cloud cover to just some scattered fair weather cumulus ahead of the seabreeze in the afternoon.
We’ll start to see high pressure aloft move out of our area a little bit more on Sunday. This should increase cloud coverage and could even introduce an afternoon shower or storm particularly inland. However, most of us will stay dry as highs head into the mid-80s in the afternoon. Outdoor activities are still go — just remember, when thunder roars, go indoors!
Looking ahead to next week, we see some of the warmest weather thus far this year in store particularly as we get into midweek and beyond. Periodic shower and thunderstorm chances will factor into the forecast, especially later in the week as a front gets nearby. But for now, enjoy the weekend as we flip the calendar to May! (Already!)
Generally good weather continues as we head into Friday and the weekend. We’ll see high pressure begin to slip offshore, allowing a little more warm and moist air to move into the area as the weekend goes on. This will allow temperatures to reach the low 80s on Saturday and run even warmer on Sunday.
With the influx of moisture and some upper-level energy coming through on Sunday, expect a scattering of showers and thunderstorms particularly in the afternoon. Definitely no washout here, just make sure you’ve got a backup plan for any outdoor activities. Remember: When thunder roars, go indoors!
The warming trend will continue well into next week, with some of the warmest temperatures so far in 2022 expected by mid-week. (But let’s enjoy the weekend first before we dive into another work week!)
Thursday continues where today left off, with a seasonably cool morning followed by a comfortably warm afternoon in the upper 70s, right where we should be at this point in April. Humidity will be low once again as dewpoints mix out into the low 40s, yielding relative humidity values approaching 25% during the peak of the afternoon. It’ll be another good day for an outdoor lunch or evening walk as a result — just make sure you’ve got some sunscreen!
After a cold front gets through tonight, we’ll see another round of cooler and drier air move into the area to set up a fantastic finish to the work week. Temperatures will run around 10° cooler tomorrow afternoon with plenty of sunshine — an excellent day for outdoor lunch, getting some walking in, or however you wish to be outside. This continues into Thursday, which will be another brilliantly beautiful day with highs once again topping out in the mid-70s. We’ll start to see a little bit of a warming trend commence on Friday as high pressure moves offshore, sending winds more southerly. Still, it’ll be another really nice day with lows in the mid-50s and highs in the upper 70s. The warming trend continues into the weekend, with highs in the low 80s on Saturday and in the mid-80s on Sunday. Enjoy!
We have an even warmer day on tap for Tuesday before storms move in late in the afternoon into the evening ahead of a cold front. We’ll start the day in the low 60s before temperatures head to the mid-80s away from the cooler coastline. The warmest it’s been so far this year is 86° on February 23rd and again on February 25; we should tie this tomorrow. (The daily record high of 92°, set in 1989, is safe.)
We’ll be watching a cold front move into the area throughout the day Tuesday. Scattered showers and thunderstorms are expected to develop ahead of this front, with brief periods of heavy rain and gusty winds the main concern. There’s a low risk that a storm could produce a damaging wind gust or two, but severe weather doesn’t look to be a big concern with tomorrow’s front.
Rain should clear the area with the front by daybreak Wednesday, leaving behind cooler, drier air and overall pleasant weather for the next couple days. High pressure shifts offshore thereafter, and a warming trend will commence heading into the weekend. We could be in the mid-80s again by Sunday with a slight storm chance to go with it. Overall, though, quiet weather remains the rule as we head into the second half of the week.
Another mostly nice-looking week lies ahead to close out April, a stark contrast to how this month got started. We start the work week as warm as we’ve been thus far in 2022, with highs topping out in the mid-80s on Monday and Tuesday ahead of a cold front. The only rain chance will be a shot at some showers and thunderstorms Tuesday afternoon and evening as the front passes by. These don’t look like they’ll be terribly organized, keeping the severe threat to a minimum.
Once the front is through overnight Tuesday into early Wednesday, we’ll see temperatures cap out around the mid-70s Wednesday and Thursday afternoons with very few clouds to speak of. A warming trend commences in earnest Friday as high pressure begins to slip back offshore, and we may very well start May off on a warm note on Sunday with highs in the mid-80s.
Overall, we largely continue to be spoiled by great weather (though we could still use some more rain given the ongoing drought). Enjoy!
