The final few days of March 2023 will be generally quiet, weather-wise (at least here in the Lowcountry), as a cold front moves across the area overnight and ushers in a cooler, drier airmass. Wednesday will be much cooler than recent days with highs peaking in the mid-60s. We’ll see a mix of sun and clouds throughout the day as a little lingering low-level moisture hangs around, but that’s about it.

The aforementioned moisture strips out later Wednesday, yielding a brilliantly sunny sky on Thursday. We’ll get off to a chilly start thanks to calm winds and clear skies from the night before with lows in the mid-40s (far from frost or freeze concerns, thankfully). Highs will reach the low 70s. All in all, not a bad day to get outside and take a walk.

Winds go around to the south beginning Thursday and this will yield a warmer Friday. Expect temperatures to peek in the upper 70s under partly cloudy skies. The 18z runs of the models indicate the potential for some showers coming ashore Friday afternoon; we’ll keep an eye on this, but for now, the going forecast is for mostly dry weather as some of you head out to pick up your Bridge Run packets.

Bridge Run forecast: Generally comfortable temperatures for the race, and rain holds off until afternoon

So far, so good for the Cooper River Bridge Run, weather-wise. Expect temperatures to bottom out in the mid-to-upper 60s as buses unload, with temperatures generally running around 70° to start the race, rising into the mid-70s by mid-morning. A mix of sun and clouds will keep things a bit on the shady side, which might be helpful as well.

Showers and thunderstorms should hold off until the afternoon and evening hours as another cold front approaches the area. Before the front, temperatures should peak around 80°. All in all, be ready with some rain gear for post-race festivities. Stay tuned to forecast updates as timings and precipitation chances continue to be refined for the rest of the week.
