Tuesday looks like a rather nice day in our part of the world with mostly sunny skies, a seasonably cool start in the low 60s, and highs in the mid-80s with relatively low humidity as high pressure’s influence on the area peaks before moisture returns starting Wednesday. I hope you can take advantage! Unsettled weather will return to the area by Thursday.

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.

Warm and muggy conditions continue for the rest of the work week as high pressure ridges aloft and at the surface. This should help keep showers to a dull roar, though I suppose with the airmass we can’t ever totally rule out a rogue popup shower (like we saw today).

We may start Wednesday with some fog once again, but that should mix out by 9-10am to yield a mostly sunny day with highs in the low to mid-90s. Dewpoints in the low to mid-70s will combine with those air temperatures to make it feel closer to 105° in the height of the afternoon, so be sure you’re taking frequent breaks and getting plenty of water if you’re outside during that time.

We’ll keep this going Thursday into Friday, with lows in the mid-70s each morning yielding to highs in the low 90s each afternoon with just a few clouds from time to time. The stacked high pressure will give any enterprising updraft trying to become a shower a very, very hard time, and rain-free conditions are expected as a result.

High pressure will bring a pause in the rain and a further uptick in temperatures starting Tuesday. We start the day in the low to mid-70s (warmer near the coast), warming to the low 90s in the afternoon under partly cloudy to mostly sunny skies. With 70s dewpoints continuing their comeback, expect heat indices in the low 100s to return to the area as well — a fair bit warmer than we’ve been used to recently, but staying below the heat advisory thresholds we got to know very well during July.

The rest of the work week will feature a cooling trend as high pressure wedges into the area from the northeast and troughing aloft persists. Wednesday should feature a lower storm chance than we’ve seen the past couple days as some drier air takes hold across the area. Temperatures start around 70°, warming to the mid-to-upper 80s in the afternoon with dewpoints in the upper 60s expected.

Thursday into Friday will feature even cooler temperatures as the wedge intensifies over the area; expect mid-80s on Thursday and low 80s on Friday. The intensifying high pressure should lead to a tightening pressure gradient which will drive some gusty winds, particularly around the coast. The onshore winds combined with the recent lunar perigee will also promote coastal flooding around times of high tide (both morning and evening) starting Wednesday evening through at least Friday. Right now generally minor flooding is expected, which is enough to close some of the more vulnerable roads in downtown Charleston.

Shower and thunderstorm chances come back into play for Thursday and Friday as well as more moisture starts to work back into the area, with the best chances of rain closer to the coast. Inland locations may even stay rain-free where drier air is expected to hold firm. No severe weather is expected, though a downpour or two can’t be totally ruled out.

Tuesday looks a lot like Monday did (in the weather department, anyway) as a front continues to meander nearby, keeping the risk for a few showers and thunderstorms in the forecast in the afternoon primarily east of 17-A. Temperatures will follow a similar curve as well — we start in the low 70s (warmer toward the coast) and warm into the upper 80s to around 90° in the afternoon.

As far as storms go, a few folks could see some locally heavy rain thanks to slow storm motions, but otherwise, no severe weather is expected.

We have a bit of a respite from the rain and the extreme humidity on the way as a front slides south of the area and stalls tonight. Some lingering moisture and a trough of low pressure will allow for a few storms to remain in the forecast on Wednesday, though, as dewpoints slowly drop through the low 70s throughout the day. We start the day in the mid-70s and warm to the upper 80s in the afternoon, capped by some of that cooler and drier air trying to move back in. Expect the best chance of showers and storms from roughly 2-10PM. A few downpours can’t be totally ruled out as the deeper moisture only really starts to scour out Wednesday night, so a flood advisory or two could still be possible.

Tuesday’s forecast will continue to feature warm temperatures and afternoon thunderstorms as Berkeley and Charleston head back to school. We have another warm start ahead of us — generally expect lows in the upper 70s once again, followed by highs in the low 90s in the afternoon. This should run a couple degrees cooler with a little more onshore flow, but it’ll still be toasty with heat indices peaking around 102° before showers and storms fire. Once again, heavy downpours could cause localized flooding, especially near swollen rivers and streams and in urban areas, so stay alert for possible Flood Advisories.

Tropical Storm Debby will continue to figure prominently in the forecast as we head through the middle of the week with continued periods of heavy rain and gusty winds before a more standard summertime pattern once again starts to take hold Friday.
