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.
Below-normal temperatures will continue this week as we remain under in the influence of high pressure anchored to the northeast, with showers taking a break for a few days before returning to the forecast for the weekend.
A few lingering showers will be possible Monday morning with a stationary front nearby, though high pressure will continue to nudge that front further and further south, clearing us out for a couple nice days. Mostly cloudy skies keep highs capped to the low 80s on Monday after a mid-60s start, but we should see gradual reduction in cloud cover throughout the day. Tuesday looks to be rather nice, with lows in the mid-60s yielding to highs in the mid-80s under partly cloudy to mostly sunny skies. We’ll start to see the front to our south buckle a little more as low pressure — which is forecast to become Hurricane Francine — moves toward the Louisiana Gulf Coast during the middle of the week. This will net us an uptick in cloud cover and dewpoints for Wednesday, but we’ll get one more rain-free day in.
The high pressure center to our northeast that’ll give us a relatively quiet start to the week will be nudged eastward, which will allow the persistent stationary front to retreat a bit northward. This will bring an uptick in shower chances beginning Thursday and lasting into at least Saturday. It won’t rain all the time, but you’ll want to consider indoor plans as a backup to any outdoor plans. High temperatures will head down a bit with the uptick in cloud cover and showers, with highs in the low 80s expected Thursday and Friday before winds get a little more due-east, bringing some warmer temperatures back to the area for the weekend. Still, though, we stay below mid-September norms, generally running in the mid-80s Saturday and Sunday.
A showery and cool weekend awaits as a trough remains draped over the eastern US, driving disturbances through the area and keeping temperatures well below normal for this point in the year.
Saturday starts in the low 70s, warming only to the upper 70s for the first time since May under mostly cloudy skies. Shower chances will be highest in the morning and will taper, but not completely cease, during the day. Rainfall amounts should be generally light, though you can never totally rule out a pocket of heavier rain or two.
Sunday’s rain chances will tick up some as the day goes on as another disturbance moves through. It’ll be another cooler-than-normal day, with a pretty seasonable start in the mid-to-upper-60s before highs once again top out in the upper 70s in the afternoon. A rumble of thunder isn’t totally out of the question as the stationary front continues to hang out, but otherwise, just be ready for some showers at times.
A reinforcing shot of cooler air will send temperatures well below normal this weekend, but first we have to get through some elevated rain chances for Friday that linger into Saturday. Friday starts in the low 70s, warming to the mid-80s in the afternoon. Low pressure developing along the front will strafe the area in the afternoon and evening hours, driving rain chances up across the area as it does so. Rain chances peak Friday evening into Saturday morning, though scattered storms will remain possible much of the day Saturday. A trough of low pressure hangs over the area on Sunday, and this keep the risk for a few showers and storms in the forecast especially in the afternoon.
Temperatures will dive even further below normal Saturday and Sunday. Expect highs to only reach about 80° on Saturday, while we may not even crack 80° on Sunday. If the high of 78° verifies, it’d be the coolest high temperature since May 18, when we also reached 78°! Fall will certainly be a bit more in the air, that’s for sure. Temperatures recover back into the low 80s as we get into next week, but remain well below early September normals.
The wedge of high pressure that’s kept things breezy and cool but largely quiet hangs on for one more day Thursday. We’ll start the day in the low 70s, warming to the mid-80s in the afternoon under a mix of sun and clouds. Breezy conditions with gusts 20-25 MPH will continue to be possible as the pressure gradient stays pinched, and we’ll keep the risk of a shower or two primarily in the afternoon. The best chance for any rain will be closer to the coast, though much of us look to get the day in rain-free.
Tuesday ended up being a rather nice day across the area as the low-level cloud cover that was originally anticipated didn’t quite materialize. Unfortunately, that reprieve may not last as the stationary front offshore buckles back toward the coast a bit more starting Wednesday. This should help spread some cloud cover back into the area, though the best shower and storm chances will reside closer to the coast. Northeasterly flow will keep temperatures well in check, with lows in the upper 60s Wednesday followed by low 70s Thursday into Friday. We’ll see highs continue to peak in the mid-80s, which remains a few degrees below normal for this point in the year.
Rain chances will tick up heading into Friday as a little more moisture works back into the area. We’ll see rain chances peak Saturday into Sunday before another front moves by for Monday, which should bring another round of cooler and drier air into the region for next week.
A front will get through the area overnight into Tuesday morning, bringing with it a cooldown that will last for the rest of the week as high pressure wedges southward into the area. Lingering showers should end Tuesday morning, and we should get much of the rest of the day in without any additional measurable rainfall. Clouds will hang around, though, and this will be commonplace for much of the week with the nearby front and ongoing high pressure wedge.
Tuesday’s temperatures will be fairly representative of what we have in store for the rest of the week. Expect lows around 70°, with perhaps some 60s further inland. We’ll warm to the mid-80s in the afternoon, tempered by the northeasterly winds and cloud cover. Dewpoints on Tuesday will run just in the mid-60s, making it the driest-feeling day of the rest of the week as they’ll trend back up to the upper 60s on Wednesday and back to around 70-71° on Thursday and Friday as the stalled front buckles back northward. Shower chances with some rumbles of thunder head up starting Wednesday afternoon and get a little higher Thursday and Friday thanks to the aforementioned front and the return of more quality surface moisture. We’ll keep this going into the weekend, too, before another front sweeps through the area with a reinforcing shot of cooler and drier air to kick off next week.
I hope everyone has gotten to enjoy the last few quiet weather days — it’s been warm, but aside from a brief shower in spots, mostly quiet. This begins to change on Labor Day as a cold front moves into the area from the north. We’ll see the risk for showers and thunderstorms increase ahead of the front, with rain chances peaking in the afternoon and evening. Severe storms are not expected, but some brief periods of heavy rain will be possible.
We’ll have one more day of seasonably warm temperatures before high pressure wedging southward drives some cooler air into the area for much of the upcoming week. Expect to start Labor Day in the mid-70s, warming to the upper 80s in the afternoon before showers and thunderstorms fire up. Heat indices should run around 100° given dewpoints in the mid-70s.
The rest of the week will feature below-normal highs in the low to mid-80s each day within a persistent northeast flow. Unsettled weather will continue, though, with the front stalled to our south and a coastal trough hanging around for the foreseeable future. It won’t rain all the time, but the risk will certainly be there. I’ll have more details tomorrow evening.
It’s a Meat Loaf-like Labor Day weekend this year: Two out of three ain’t bad. We’ll continue this stretch of warm but mostly quiet weather (aside from a stray shower on the seabreeze) for Saturday and Sunday. Expect to start each day in the mid-70s, warming to the low 90s in the afternoon. Heat indices will generally run in the upper 90s — certainly still hot, but it could (and has!) been much worse.
Attention then turns to a front that will move into the area on Monday. We’ll see the risk for showers and thunderstorms increase throughout the day as the front sags south into the region. Temperatures will peak around 90° one more time before the front ushers in cooler air and continued unsettled weather as we get into the working portion of next week. Severe weather doesn’t look to be a major concern, but we could see brief periods of heavy rain and lightning from any thunderstorm that fires. Remember: when thunder roars, go indoors!
The good news is that much of the upcoming Labor Day weekend is looking pretty good: expect highs generally to run in the low 90s each afternoon, with heat indices in the upper 90s expected after taking into account dewpoints in the low to mid-70s. A stray shower or storm can’t be completely ruled out, especially as you head inland, but otherwise we should stay mostly quiet across the area.
A pattern change is in the offing, though, that will help drive a front toward the area for Monday. We’ll start Labor Day in the mid-70s once again, warming to the low 90s in the afternoon. As the front pushes southward, the risk for showers and thunderstorms will increase, with a decent shot at some storms arriving by Monday evening. This will kick off a stretch of unsettled — but cooler — weather as the front stalls to our south and high pressure wedges southward across the area. A nearby coastal trough should keep rain chances in place for much of next week, though we have a few more summery days to enjoy before then!
Our stretch of high-pressure-dominated weather continues on Thursday as warm temperatures and mostly sunny skies continue. We start the day in the mid-70s, warming to the mid-90s in the afternoon. Dewpoints in the low 70s will ultimately yield heat indices around 100-101°. A few patches of fog will be possible in the morning, but otherwise, another generally quiet weather day is expected.
