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.

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.

/ 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.
