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.
We get off to a fairly chilly start on Tuesday as lows bottom out in the upper 40s thanks to clear skies and light winds. This will be the low-water mark (so to speak) for temperatures, though, as we head into the rest of the week. Highs on Tuesday top out in the mid-70s once again, perhaps a degree or two warmer than we saw on Monday. All in all, another nice October day.
The story of this week’s weather will be high pressure keeping a firm grasp on the area for the rest of the week (and maybe even the rest of October). This will lead to generally quiet weather, with a warming trend bringing us into the low 80s starting around midweek. Monday will be the coolest of the set in the wake of a dry cold frontal passage; we start the day around 50° and warm into the low 70s in the afternoon with just a few clouds. Tuesday starts a touch cooler, but the warming trend will begin with temperatures reaching a little warmer in the afternoon. A decent stretch of above-normal warmth takes hold from there, with variable cloud cover but little else to write home about as moisture is generally scant. All in all, it’s not a bad week to get the car washed (note to self) and enjoy some outdoor lunches.
The only concern may end up being coastal flooding at times of high tide possibly starting as early as Tuesday. Winds will be out of the northeast as high pressure settles in to our northwest, and this combined with the upcoming full moon will once again start to send water levels above coastal flood criteria as we head into the latter half of the week. Keep an ear out for Coastal Flood Advisories from the National Weather Service.
After an occasionally stormy Friday, we have a great looking weekend of weather ahead. Skies clear out overnight Friday in the wake of the front, and by Saturday morning, we’re waking up to brilliant sunshine and temperatures in the low 50s. It’ll be a predominantly sunny day with temperatures topping out in the low-to-mid-70s.
Sunday turns a little warmer, but it’ll remain rather comfortable. Lows in the upper 50s give way to highs in the mid-to-upper 70s in the afternoon with a few clouds at times and a gentle northwesterly breeze. A reinforcing front makes a dry passage late Sunday evening, and this will cool temperatures back down for Monday. Peeking ahead into the forecastable future, there’s very little sign of much in the way of rain as we get into the home stretch of October. This isn’t too abnormal as October is climatologically a fairly dry month here in the Lowcountry, but we are almost an inch off pace still for the month.
Showers and a few thunderstorms re-enter the weather picture for Friday as a cold front moves by, but it’ll be worth it as we have a gorgeous weekend ahead.
We start Friday in the mid-50s with dewpoints steadily rising throughout the day. Showers and thunderstorms will approach the area from the west as the day goes on, with storms possible perhaps as early as 1-2 PM, but most likely in the late afternoon to early evening hours. A storm or two could even be on the strong side, with damaging wind gusts the main concern. Rainfall between a quarter and half-inch is generally expected, with some spots under- and over-performing as is common with these kinds of convective setups. Due to the ongoing dry conditions, though, flooding is not expected to be an issue.
From there, the weekend looks great. Skies clear nicely for Saturday, and northwesterly flow will yield a rather beautiful day with lows in the mid-50s yielding to highs in the mid-70s in the afternoon with nary a cloud to be found. Sunday will be another really nice day with temperatures generally similar to Saturday’s, though we’ll see a bit more in the way of scattered clouds ahead of a dry frontal passage late. All in all, it looks to be a fantastic weekend to get out and do stuff.
Expect clouds to be on the increase on Thursday as a coastal trough develops nearby, spreading some cloud cover onshore. Somewhat more southerly trajectories will allow temperatures to run a little warmer (but still below normal). Expect to start the day in the low-to-mid-50s before temperatures head to the mid-70s in the afternoon. Despite increasing clouds, expect one more rain-free day ahead of a cold front arriving Friday.
Sun continues for a couple more days before unsettled weather arrives later Friday with a cold front. Wednesday could be the chilliest start since April 18 if the NWS forecast verifies, with low to mid-40s common away from the locally warmer coastline. Temperatures will warm into the low 70s under mostly sunny skies, a couple clicks warmer than was observed on Tuesday.
Thursday runs even a little warmer as winds go a little more east to southeast, allowing some more moisture to work into the area. Expect to start Thursday in the low 50s before warming to the mid-70s under generally partly cloudy skies.
Our next rain chance arrives Friday afternoon into the evening ahead of a cold front. This will be the warmest overall day of the set as lows generally start in the mid-to-upper 50s before reaching highs in the mid-70s in the afternoon before showers begin. Right now, it doesn’t look like we’ll get much in the way of rain; generally around a quarter-inch at most. Of course, that doesn’t preclude a few spots from seeing some slightly heavier or lighter amounts.
Once the front is through, we have an excellent, seasonable weekend of weather on tap with lows in the low 50s and highs in the low 70s each afternoon with plenty of sunshine.
Tuesday will be another seasonably cool day under mostly sunny skies as high pressure remains in control at the surface with troughing aloft. After an upper-level disturbance passes by overnight Monday, skies will clear, allowing temperatures to fall into the upper 40s away from the coast for Tuesday morning. Temperatures then rise into the upper 60s, with the potential for a couple spots to hit 70°. Overall, a very seasonable October day across the Lowcountry.
Overall, we’ve got a pretty nice week ahead with temperatures running generally below normal and only one passing rain chance on Friday.
A trough moving by overnight Sunday into Monday could bring a few showers early Monday morning, but those will be done by daybreak, and we should see a partly cloudy day with highs topping out only in the mid-to-upper 60s, some 10° below normal for this point in the year. (Might be a little taste of sweater weather?) We start Tuesday in the upper 40s with highs once again peaking shy of 70° with more sunshine expected. We have a similarly cool start Wednesday but with unfettered sunshine, expect highs to top out in the low 70s. Thursday runs a little warmer with lows starting in the low 50s and highs in the mid-70s with a little bit more in the way of cloud cover (but still plenty of sun, too).
Our only real rain chance this week arrives ahead of a cold front on Friday. Generally, expect a scattering of showers in the afternoon and evening ahead of the front, but nothing too outrageous. Highs will run in the mid-70s. Behind the front, a modest cooldown will ensue, but it should be a really nice weekend with lows in the 50s and highs in the low 70s each afternoon.
Low pressure will move northward across the area overnight Friday into Saturday morning, keeping shower chances (and maybe a rumble of thunder) in the forecast through roughly mid-morning. It’ll be a mild start, with lows bottoming out in the upper 60s to around 70°. Highs will warm into the low 80s, and it’ll generally be a muggy low 80s as dewpoints remain elevated in the upper 60s. Cloud cover will steadily decrease as the day goes on as low pressure continues to move further away.
A reinforcing cold front arrives overnight Saturday into early Sunday morning, and this will bring a much more noticeable change to the airmass. Dewpoints will drop into the 50s, and highs will only top out in the mid-70s in the afternoon. Cloud cover will increase as we get into the evening as a trough approaches the area, but we should still get plenty of sunshine in.
We stay unsettled — but turning warmer — on Friday as winds turn a little more onshore thanks to low pressure developing over northern Florida and southern Georgia. This will also help to keep showers in the area for a good bit of the day, so be ready with the rain gear just in case. Some breaks in the clouds may bring some sunshine, but cloudiness should remain the main feature. Expect highs to top out in the mid-70s.
Showers will continue heading into Saturday as low pressure moves northward across the Lowcountry throughout the day. The low should clear the area by afternoon, and from there, we should start to see some slightly drier air work into the area. There should be at least some peeks of sun Saturday afternoon, so the day’s not a total loss, and we’ll get to the low 80s — as warm as we’ll be for the foreseeable future, it’s worth noting.
A stronger cold front comes through overnight and brings a much better shot of cooler and drier air to the area for Sunday. That’ll help to clear some of the cloud cover out a bit and help highs top out only in the mid-70s in the afternoon. Cooler and drier air will continue to work in overnight Sunday, and we’ll have a stretch of cooler-than-normal temperatures for much of next week.
