Showers and maybe a few thunderstorms will continue to be in play for the forecast as we get into the midpoint of the long Memorial Day weekend, though the greater activity will continue to be found along and west of the I-95 corridor. For Sunday, we can expect the bulk of our activity likely during the morning and early afternoon hours before the seabreeze pushes inland and takes most of the activity with it. However, showers will be possible throughout the day, so be ready to move outdoor plans inside just in case a shower or thunderstorm approaches.
After another day in the upper 80s on Wednesday — just missing 90° by a couple degrees at the airport — we should turn even a little warmer for Thursday with plenty of sunshine to be had. It’ll be a bit of a balmy day in general as lows in the upper 60s warm to the low 90s in the afternoon. Mid-60s dewpoints will keep the heat index in check, though it may feel a tick or two warmer than the air temperature.
More sunshine is in the offing for Tuesday with high pressure in continued control of our weather. The air will have a bit of an early summer feel to it with lows bottoming out in the mid-60s, warming to the upper 80s and perhaps approaching 90° in the afternoon. Dewpoints will mix down to the mid-60s in the afternoon, so while it won’t be excruciatingly humid, there will definitely be a bit more heaviness to the air, so to speak.
A cold front will swing through early Thursday with high pressure to build in behind it. Temperatures will start in the low 60s, warming to the low-to-mid-80s in the afternoon with northwesterly winds around 10 MPH. The downslope flow will dry out the atmosphere pretty nicely, allowing for mostly sunny skies with maybe a few fair weather clouds. The drier air will make the 80s highs feel a little more comfortable, too. Overall, it’s a good day to try to get some sunshine in the midst of the daily grind.
High pressure nudging in from the north will keep cloud cover in place and cool us off a bit for Tuesday after the third 90° day of the year on Monday. We’ll start the day in the upper 50s, warming to about the mid-70s given the expected cloud cover. A shower could get close to far southern Charleston County during the day, but most of us should stay rain-free.
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.
Well, we are running out of ways to tell y’all that it’s going to be warm and dry. High pressure remains the main weather driver across the area, keeping temperatures warmer than normal and rain chances virtually nil. We’ll start the day in the low 60s, warming to the mid-80s in the afternoon away from the coast, where onshore flow from the south will help keep temperatures pinned to the upper 60s. Expect downtown to peak a few degrees cooler, generally in the upper 70s to low 80s depending on your proximity to the water.
Stacked high pressure remains in control for Tuesday, yielding plenty of sunshine and a continuation of our warming trend. We’ll start Tuesday in the upper 50s to low 60s, warming to the mid-80s away from the coast. Expect downtown to peak in the upper 70s, while we may not get out of the upper 60s right at the beaches where the adjacent Atlantic waters continue to run in the upper 60s.
Cool high pressure remains the primary weather driver on Tuesday, though temperatures may tick up a degree or two compared to Monday’s high of 69°. We’ll keep the clouds around for a majority of the day, though some peeks of sun should start to filter through later in the day. Generally, expect to start the day in the mid-50s, warming to the low 70s in the afternoon. Northeasterly winds will kick up a little bit throughout the day, with gusts around 20-25 MPH possible.
Seasonable warmth continues for Thursday as well as heading into the weekend with high pressure in control for a few more days. We’ll start Thursday in the upper 50s to near 60°, perhaps with some patches of fog again in the morning. Any fog dissipates fairly quickly after sunrise, and temperatures will head back into the low 80s under mostly sunny skies.
