Tuesday: Another warm and somewhat humid day; stray shower possible inland

/ June 9, 2026 at 12:02 AM

High pressure at the surface and aloft remain the main weather drivers heading into Tuesday, keeping us on the warm and humid side. We’ll start the day in the low-to-mid-70s, warming to around 90° in the afternoon. A weakening front to the north could kick up some stray showers generally for inland Berkeley, but the ridge aloft will likely keep a lid on more robust thunderstorm development. A similar setup will persist Wednesday before the ridge flattens out a bit, allowing for more shower and thunderstorm development getting into late week.

The week ahead: Decidedly summertime with afternoon storms and building heat

Heat and humidity will feature prominently in the forecast this week as a more summertime pattern takes hold.

Weekend forecast: Seasonably warm and generally quiet

/ June 5, 2026 at 9:38 PM

This weekend will be warm and a little more humid as surface high pressure moves into the Atlantic, sending winds more southerly behind it which turns the moisture tap back on. We should stay quiet, though, with ridging aloft and a pretty solid pocket of dry air hanging in there for a couple more days. We’ll see some clouds at times, particularly of the high variety, but otherwise expect plenty of sunshine to still break through for the weekend. Temperatures Saturday start in the mid-60s, warming to the low 90s in the afternoon, while Sunday feels much more like summer with a low around 70° and highs in the low 90s.

Rain chances gradually return as we get into the start of next week; these will generally be of the popup variety. Highs Monday top out in the mid-90s, while upper 80s to around 90° will be more common through the middle of next week.

Friday & the weekend: 90s return

/ June 4, 2026 at 10:38 PM

High pressure at the surface and aloft will remain the primary weather driver for Friday and the weekend, with a bit more in the way of heat returning to the area starting Friday. Temperatures Friday start around 60°, warming to around 90° in the afternoon under mostly sunny skies. Dewpoints will remain generally in the 50s before the seabreeze pushes in a little more humid air from the Atlantic later in the day, but even then, they’ll only run in the low 60s with cooling temperatures behind them. It will be one of those rare days where the heat index may actually run slightly cooler than the actual air temperature, in fact, as the relatively dry air will allow sweat to do its thing.

Thursday: Lots of sun, a little warmer

/ at 12:19 AM

Another comfortably warm day lies ahead for Thursday as high pressure at the surface and aloft remain the dominant weather features. Temperatures will once again start well on the cool side of normal for this time of year, bottoming out in the upper 50s away from the coast. We’ll warm to the mid-80s in the afternoon, but low-50s dewpoints will help not to make it feel terribly uncomfortable.

Rest of the work week: Plenty of sunshine, turning warmer

/ June 2, 2026 at 10:42 PM

Rain is done for a few days as dry high pressure builds down into the area, bringing about comfortable warmth as we get down the home stretch of the work week. It won’t feel like June on Wednesday as temperatures bottom out into the mid-50s away from the locally warmer coastline. Expect highs to peak in the low 80s in the afternoon with nearly unfettered sunshine as deep dry air sets in. Savor the low humidity because we don’t have too many more days like this left for a while!

If the beach is in your plans, be aware of a high risk of rip currents during the day Wednesday due to the ongoing northeast flow. It’s best to stay out of the water on days like this

Tuesday: A scattering of storms ahead of another front

/ June 1, 2026 at 11:50 PM

We should see another scattering of showers and thunderstorms on Tuesday in association with a cold front that will make for a rather nice second half of the work week. Temperatures will start in the mid-to-upper 60s, warming to just about 80° in the afternoon as the front pushes further southward and drier air begins to find its way in. Dewpoints should fall nicely late Tuesday into Wednesday, setting up a stretch of spring-like conditions through Friday.

The week ahead: Unsettled start, but turning quieter and warmer

/ May 31, 2026 at 9:51 PM

Meteorological summer begins on Monday, but it isn’t going to feel much like it for a few days with unsettled weather to start and cool high pressure for midweek before temperatures rebound toward 90° by the weekend.

Weekend forecast: Stormy Saturday, drier Sunday

/ May 29, 2026 at 11:44 PM

Rain spreads back into the Lowcountry on Saturday as a stationary front buckles back northward across the area. A bit of upper-level energy will also kick in some lift, and that’ll result in scattered to numerous showers and thunderstorms at times on Saturday. Right now it looks like the best chances will be found in the morning through early afternoon hours, but a shower or storm just can’t be ruled out during any part of the day. Temperatures will start in the low 70s, warming to the mid-80s in the afternoon at best.

Friday & the weekend: Turning cooler, still unsettled at times

/ May 28, 2026 at 8:24 PM

A cold front pushing southward overnight will stall out to our southwest, pushing some drier air into the area in the meantime and cooling things off a few degrees compared to the past few days. Friday still starts in the low 70s, but still a few degrees cooler than Thursday. Temperatures will head to the mid-80s in the afternoon with a few showers or storms possible midday, but otherwise, expect a quieter weather day compared to Thursday’s rambunctious thunderstorms which brought some much-needed rain to the Highway 17 corridor and points east.
