Showers overspreading the area Wednesday evening will continue for much of Thursday as low pressure moves offshore, allowing high pressure to wedge in behind it from the northeast. While rain chances taper heading into the evening, cloud cover should remain robust and temperatures on the cool side thanks to the wedge. We shouldn’t get out of the upper 60s, in fact. All in all, Thursday looks to be a good jacket or hoodie kind of day.

Well, I think we all know what the big weather story will be heading into Friday and the weekend — a really solid shot of cooler and drier air that arrives Sunday for the season’s first true taste of fall. To get there, we’ve got to get through a frontal passage, though limited moisture will keep shower and storm chances relatively low on Friday. Highs top out in the mid-80s after starting in the upper 60s, which is on the mild side of normal for this point in the year. Drier air begins to punch into the area on Saturday, though the cooler air will lag a little bit. Expect Saturday to be a pleasant day, though, with highs topping out in the low 80s in the early afternoon before the cooler air begins to do its thing.

We’ll wake up Sunday in the low 50s, which will be the coolest low since we started May 4th at 48°. Brilliantly sunny skies will aid temperatures getting into the low 70s in the afternoon. It should be a really beautiful day to get out and do stuff. You may very well need a light jacket or hoodie, even. And while this shot of “chilly” air will be somewhat short-lived — we warm back to the 80s by Tuesday — it’s a sign of what’s to come as we get deeper into October and fall.

After a fairly cool and cloudy day on Thursday, cloud cover breaks up a bit for Friday into the weekend, and this will allow temperatures to return to the low to mid-80s each afternoon. Temperatures will peak Saturday before a little cooler air works into the area Sunday. Overall, it looks pretty good to get out and do stuff, especially with the northeasterly winds backing off a bit more as the pressure gradient relaxes.

Rain will generally be a non-factor in our weather starting Thursday (except for maybe some brushes near the coast) heading into Friday and the rest of the weekend. We start the day around 65° with some cloud cover in the area. A northeasterly breeze courtesy of high pressure wedging into the area from the northeast will continue to keep temperatures down to about 80° at warmest in the afternoon with cloud cover hanging around. We should see some sun break through at times as well, though.

The main weather concern will be coastal flooding at times of high tide, and it could be somewhat disruptive to the morning commute in particular. High tide around 7:30am will top out around 7.9′, which is the high end of moderate flood stage in Charleston Harbor. The evening high tide should reach even higher, with water levels around 8.1′ expected around 8pm. Watch for road closures as you commute Thursday morning and then again a little later Thursday evening, particularly if downtown is in your plans.

The weather for Friday and at least the first part of the weekend will be dictated in part by Potential Tropical Cyclone Sixteen, which is forecast to become a tropical storm — probably named Ophelia unless an Atlantic wave develops faster than forecast — as it approaches the NC Outer Banks this weekend. We will stay well on the western periphery of the storm and only feel the occasional shower on Friday, with a gusty breeze for most of us. It will be a rough go at the beaches — probably not the best day to go with gusty winds, high surf, rip currents, and some afternoon coastal flooding around the 1:45 PM high tide. Erosion is certainly not out of the question as well. Highs on Friday top out in the low 80s.

Showers depart by Saturday as maybe-Ophelia moves northward away from us. We start the day in the low 60s with temperatures heading into the low 80s once again under mostly cloudy skies. We should see some breaks in the clouds develop particularly as we get later into the day, though. Winds will remain somewhat breezy, but not to the degree we’ll see Friday.

Sunday is the pick day of the weekend as far as outside stuff goes; lows in the low 60s give way to highs in the mid-80s under mostly sunny skies. Another plus to Sunday: Winds will have tapered off considerably, too, as maybe-Ophelia loses tropical characteristics around the Delmarva Peninsula.

Rain-free conditions come to an end Thursday as we should see some scattered showers from time to time courtesy of developing low pressure well offshore. We’ll get off to a much warmer start than the previous couple days, with lows across the metro in the upper 60s to around 70°. Expect a scattering of showers and maybe some rumbles of thunder throughout the day, coming ashore within onshore flow. A few heavy downpours can’t be ruled out. Highs top out in the low 80s.

We’ll get close to coastal flood stage with Thursday afternoon’s high tide, forecast to peak around 12:41 PM, thanks to the increasing northeasterly flow, which tends to pile water up quite efficiently, so we’ll need to keep an eye on that in case some salt water works into the area.

We get a break in the humidity Friday and Saturday as cooler and drier high pressure builds in from the northwest. Temperatures get off to a nice start on Friday, and persistent northeasterly winds will keep highs capped in the mid-80s as cloud cover decreases. Dewpoints, meanwhile, will plummet into the mid-50s, and this will allow relative humidity values to drop below 40%, making for rather comfortable warmth.

Saturday is probably the best day of the set to get outside, as we start the day in the low 60s before heading back to the mid-80s in the afternoon under mostly sunny skies. Dewpoints will again mix out into the mid-50s during the day, and we’ll have another round of sub-40% humidity.

High pressure slips offshore overnight Saturday, and by Sunday dewpoints will be rebounding back into the mid-to-upper 60s. Another front will be approaching the area during the day, and this will be the impetus for showers and thunderstorms as we get later into Sunday and Sunday evening. Highs top out in the mid-80s. Overall, expect temperatures to remain at or a little below normal as we head into next week.

A cold front will slip offshore early Thursday morning, but we won’t quite be feeling it just yet as some showers and thunderstorms will still be possible as moisture lingers across the area during the day Thursday. Highs top out once again in the upper 80s before showers and a few storms fire. Instability isn’t great and severe weather is not expected, though some heavy rain will yet be possible at times. The best chance to see a shower or storm looks to be in the afternoon and early evening hours.

A stalling cold front and a cutoff low aloft will combine to bring shower and storm chances back to the area starting Friday afternoon, peaking on Saturday, and then gradually tapering on Sunday. Highs on Friday top out in the low 90s, with the best chance for showers and thunderstorms generally being found along and ahead of the seabreeze. With the upper low drifting across the area Saturday, showers and thunderstorms could fire at any point, with some guidance hinting at Saturday getting off to a bit of a soggy start as showers and thunderstorms drift inland. Highs on Saturday top out in the mid-to-upper 80s given the rain and cloud cover. We’ll see the upper low lift out of the area on Sunday, decreasing the risk of showers and storms somewhat, but coverage should still be decent given the nearby front.

We have one more rain-free and rather warm day coming up on Thursday. Expect highs to once again top out in the mid-90s under partly cloudy skies, with some humidity mixing in to drive heat indices to the upper 90s to around 100°. It’s worth noting that the NWS forecast high of 95°, if it did indeed come to pass, would tie the daily high temperature record set in 1941 and then tied in 1947 and 2019. (For reference, last year’s high on September 7 topped out a degree shy of the record.) Ridging will weaken throughout the day, but much of us should expect to get the day in rain-free. I don’t know that I’d totally rule out a shower or storm closer to I-95, though.
