The next seven days: A chilly and wet Saturday gives way to increasingly warm days; next front Thursday

/ May 1, 2026 at 6:54 PM

We’re taking a look at the next seven days tonight as I’ll be taking a bit of a break over the next few days. A more regular posting schedule resumes Friday!

A rain-cooled day is on tap for Saturday — not quite peak air show weather, that’s for sure — as we may challenge a record cool high temperature. The coolest high temperature on record for May 2 is 63°, set in 1978; the NWS forecast for the airport currently calls for highs to reach about 64°. It’s gonna be close! As mentioned, some much needed rain will be falling throughout the day, with some rumbles of thunder possible with some elevated instability. No severe weather is anticipated, though. It’ll be generally on and off through late afternoon before tapering off in the evening. Many of us should see an additional inch to inch and a half of rain before it’s over — quite a nice sight given the ongoing severe drought.

Friday & the weekend: Wet and cool start to May

/ April 30, 2026 at 11:38 PM

After completing what should go down as the second-driest April on record (only by virtue of measurable rainfall over the past two days), we will get May off to a more unsettled start with some much-needed rain followed by a cool but sunny Sunday. We will also need to keep an eye on tides for possible coastal flooding concerns into the weekend.

Rest of the work week: An unsettled end to a dry April

/ April 28, 2026 at 7:07 PM

We will close a bone-dry April out with a couple more chances for showers and thunderstorms as another cold front approaches the area with disturbances riding along it. One such disturbance fell apart as it reached the Lowcountry today, giving us another trace of rain at the airport. Officially, though, rainfall totals for the month of April remain at 0.01”, which currently ties 1972 as the driest April on record. With any luck, though, we should not end up there, though a top-five driest April on record certainly appears to be in the cards.

The week ahead: A few more rain chances, not quite as warm

/ April 26, 2026 at 11:57 PM

One of the driest Aprils on record will come to a somewhat unsettled end this week as the pattern starts to finally flip toward something a little more favorable for rain chances. We’ll run a little cooler, too, especially as we start May.

Weekend forecast: Storms return, but don’t expect much rainfall

/ April 24, 2026 at 11:04 PM

The main weather story for the weekend will be a cold front that’ll move into the area later Saturday, which will help to bring about the first significant rain chance in weeks. A few short-lived seabreeze thunderstorms got close enough to produce a trace of rain at the airport today — the first non-zero rainfall recording at the airport since April 6 — but the unmeasurable sprinkles have kept April 2026’s rainfall total at 0.01″ as we head into the month’s final week, currently in a tie with 1972 for the driest April on record.

Friday & the weekend: A little much-needed rain Saturday night into Sunday

/ April 23, 2026 at 11:53 PM

After one more mostly sunny and dry day Friday, the pattern finally turns a little more unsettled starting Saturday as a cold front advances toward the area. This front will help stir up some showers and maybe some thunderstorms later Saturday into Sunday. Rainfall amounts will generally be light — a quarter-inch may be awfully generous from this setup — but everything helps.

Temperatures Friday and Saturday run in the mid-to-upper 80s in the afternoons after starting in the upper 50s Friday and the low-to-mid-60s on Saturday. From there, a backdoor cold front looks to sink southward across the area on Sunday, which will take temperatures down a few degrees with highs in the low-to-mid-80s expected. With the exception of Monday, though, generally expect warmer-than-normal temperatures to close out April.

Thursday: Mostly sunny, but a bit smoky

/ April 22, 2026 at 10:12 PM

High pressure will remain in control on Thursday, keeping mostly sunny skies in place. It won’t be all sunshine, though, as smoke from nearby wildfires in Georgia drifts into the area, which could have negative impacts on air quality. An Air Quality Alert is in effect for the Lowcountry through Thursday evening as a result; people who have sensitivities to poor air quality should limit time outdoors. Temperatures will take another step up as southwesterly winds help pump in warmer air; expect lows in the mid-50s to warm to the mid-to-upper 80s in the afternoon.

Rest of the work week: 80s return

/ April 21, 2026 at 8:23 PM

High temperatures return to the 80s on Wednesday as high pressure begins to move out into the Atlantic. This is the continuation of a warming trend that will last into the weekend, which will feature temperatures returning to the mid-to-upper 80s ahead of a front that will bring the first decent chance of rain in a couple weeks.

Tuesday: Another pleasant day

/ April 20, 2026 at 10:43 PM

High pressure remains in control for Tuesday (and for the next few days), yielding plenty of sunshine and comfortably warm temperatures. We start the day in the low 50s and will head to the mid-to-upper 70s in the afternoon away from the locally cooler coastline. Overall, it should be a nice day to get out and about if you are able.

The week ahead: A cool start, but warming back up

/ April 19, 2026 at 10:06 PM

Dry weather continues for the next few days, but we may start to see the pattern begin to flip this weekend to something a little wetter to close out April.
