Another round of scattered to numerous showers and thunderstorms is expected Thursday, particularly in the afternoon and evening as daytime heating and some upper-air help kicks in, though a shower or storm will be possible for much of the day. Before storms fire, expect to start the day in the upper 60s, warming to the mid-80s under a mix of sun and clouds. Dewpoints around 70° will yield heat indices around 90°.

The risk for severe weather is looking a little lower than it did on Wednesday, with the best risk displaced to the south, but a storm with a damaging wind gust or two and some hail can’t totally be ruled out.

More showers and thunderstorms are in the forecast for Tuesday afternoon and evening as a stalled front hangs around the area. First, though, we’ll start the day in fine June fashion with lows around 70° in the morning. Temperatures should head to about 90° in the afternoon before thunderstorms fire. Dewpoints in the mid-60s should yield heat indices around 92° — nothing totally out of hand for this point in the year, but certainly steamy.

I hope y’all enjoyed the relative dearth of humidity on Saturday — it was a rare June day in the Lowcountry where the heat index was cooler than the air temperature — because humidity will return to the area during the day Sunday as a warm front lifts north of the area. We start the day in the mid-60s before warming into the upper 80s; dewpoints heading back into the upper 60s will make it feel more like the low 90s at the height of the heat of the day. From there, we should start to see scattered showers and thunderstorms develop and move eastward across the area. Instability and shear aren’t super-great, so the risk for any severe storms looks limited — but remember, all thunderstorms are dangerous because of the lightning they produce. Regardless, it doesn’t look to rain all day at any one location — as always, just make sure you have an indoor backup plan for outdoor activities.

Our string of stormy afternoons looks to continue on Thursday as a cold front slowly moves through the area. Showers could fire as early as mid-morning, but the better chance of thunderstorms arrives in the afternoon and evening hours as we get some daytime heating in place. Much like the past two days, a few storms could produce gusty winds and hail, so be on the lookout for quickly changing weather conditions and be ready to move indoors quickly if storms approach.

With the front in the area, highs will top out somewhat lower than Wednesday’s 92° — expect generally mid-80s across the region before thunderstorms fire in the afternoon. We could run a little warmer — or cooler — depending on how fast the front gets south of here. (That could also modulate our thunderstorm chances a bit, too.)

Finally, there are no air quality concerns with the ongoing wildfire smoke that is being transported south into the eastern United States from Quebec, though we will continue to see a milky haze in the sky, which should persist into the weekend.

June makes a triumphant return on Tuesday as high pressure slips offshore and winds go southwesterly, transporting more warm and humid air into the area. Temperatures should reach 90° after a mid-60s start under partly cloudy skies. We should see a few isolated storms pop up in the afternoon as the seabreeze makes its inland trek. A strong pulse storm with gusty winds and maybe even a little hail can’t be totally ruled out given decent instability; this will be most likely near outflow boundary collisions.

There will be a risk of some minor coastal flooding around the 10:58 PM high tide, but the westerly component to the wind will make this a much more limited threat compared to the past few days. Still, watch for some salt water around the Citadel and on Lockwood late Tuesday evening.

A cold front will move through the area early Sunday, which will cap highs in the low 80s — well below normal for early June in the Lowcountry. We’ll see a mix of sun and clouds as high pressure wedges in from the northeast, but rain is not expected with the drier airmass filtering in. It’ll be a little breezy — gusts 20-30 MPH will be possible out of the northeast, especially at the beaches and on elevated surfaces such as the bridges.

The main weather concern for Sunday revolves around coastal flooding. A water level over 8′ is expected once again with Sunday evening’s high tide, which peaks around 9:10 PM. This will produce major coastal flooding once again, closing numerous roads in downtown Charleston and potentially causing disruptions on barrier islands as well. This degree of flooding is extraordinarily rare for June, with only three major flooding events on record — once in 1982 and twice in 2009. Be ready to use alternate routes if you are out and about Sunday evening.

Thursday’s forecast is quiet and a little cool for this point in the year as we kick off climatological summer on June 1. Temperatures will generally run a couple degrees below normal on Thursday as cloud cover and a northeast breeze helps to keep things a little on the “cool” side. (Quotes around “cool” because it’ll still be warm and a little muggy, too.) As is customary for June, a shower can’t be totally discounted within this regime, but the vast majority of us get the day in rain-free.

After what’s turned out to be a really beautiful Memorial Day, we head back to work and school on Tuesday with similar, if not slightly warmer, weather expected. We’ll start the day a few degrees warmer — generally around the mid-60s — and highs should warm to the mid-80s in the afternoon. There’s a risk for a stray shower or thunderstorm in the later afternoon and early evening hours as the seabreeze gets rolling, but otherwise, the vast majority of us get Tuesday in rain-free as well.

The sun will make a return to our skies for Memorial Day as surface low pressure continues to move away from the area and westerly winds dry things out a bit. We start the day much cooler than normal, with lows bottoming out in the upper 50s. (The record low of 53° set in 1961 remains safe.) Sunshine and the aforementioned westerly winds should help highs top out in the low 80s — a couple ticks below normal as well, but certainly much more seasonable than the 60s and 70s of recent days. The only fly in the ointment may be a stray thunderstorm or two in the afternoon as the seabreeze moves inland. If the beach is in your Memorial Day plans, keep an eye out later in the afternoon as storm motions will be toward the coast. Otherwise, no concerns.

We are through the worst of our experience with the coastal storm that has been bothering us for the better part of two days, and improvement will start to show itself on Sunday. We should see showers mostly shut down around daybreak or so, but I’m not sure a stray or two can be totally discounted throughout the day. We should start to see some breaks in the clouds, and by the evening, I suspect we’ll have at least some sunshine to close out the day. Temperatures will remain well below normal for this point in the year, topping out in the low 70s after starting the day around 60°.
