Area Forecast Discussion National Weather Service Charleston SC 731 PM EDT Fri May 16 2025
SYNOPSIS
Broad high pressure will persist through the weekend. A weak cold front may push over the region early next week, remaining generally stationary through Tuesday. A stronger cold front is timed to sweep across the region Wednesday into Wednesday night.
NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Early this evening: All is quiet as the sun sets on a very hot day. We will continue to see some thin cirrus and a bit of mid- level cloudiness pass through, but otherwise not much to talk about. Radar imagery shows that the sea breeze remains pinned along the GA coast, where it likely won't make much inland push.
However, as you go up to the Charleston County coast the sea breeze should reach Summerville soon and will continue to progress inland. Expect another warm and muggy night, very summer-like. Lows are expected to only dip to around 70 in most areas.
SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/
Saturday: Possible chance of showers and thunderstorms in the morning due to outflow from previous night's storms in the Ohio Valley. Some of the recent high res. guidance has been indicating that some convection could reach the region by ~15-16Z and then quickly weaken over the area as we head into the afternoon. Given the dry-air aloft and mid-lvl flow weakening throughout the day, the severe potential with these storms appears low. Expect highs in the low to mid 90s, and overnight lows to dip into the upper 60s to low 70s (mid 70s near the coastline).
Sunday: A wavy stationary front might linger over the region throughout the day, as a MCS sourced from the Mid-Mississippi Valley tracks closer, reaching the Lowcountry by the afternoon (~18-19Z). There remains some uncertainty with this setup as it's largely dependent on the placement of the stationary front.
Recent runs of the NAM/ECMWF has kept the forecast rather dry, while the GFS has been indicating that some type of disturbance will possibly coincide with the afternoon seabreeze and allow convection to develop in the afternoon. With the temperatures relatively high and dewpoints in the low 70s, there just might be enough instability for isolated to scattered showers and thunderstorms to develop. By sunset, convection should track offshore and temperatures will drop into the upper 60s to low 70s overnight. Given the possible rainfall in the afternoon, patchy fog could develop overnight...however the forecast does not include fog at this time.
Monday: Upper-lvl ridging from the Gulf will govern the overall pattern on Monday, with heights gradually increasing throughout the day. With mostly sunny conditions, highs will climb into the low to mid 90s. A seabreeze will likely develop in the afternoon and advance inland, thus it wouldn't be a surprise to see some isolated showers and thunderstorms develop along with this.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Tuesday: The axis of the H5 ridge from the Gulf will continue to dominate most of the region on Tuesday and allow highs to reach into the low to mid 90s with upper 90s in SE Georgia.
These temperatures could definitely challenge the the record temperatures, see climate section below. With hot and dry conditions, thanks to the ridging aloft, any precipitation seems unlikely and kept the forecast dry. Overnight, temperatures will dip into the upper 60s to low 70s.
Wednesday through Friday: A strong upper- lvl low situated over the Mid-west will continue to advance northeastward overhead, as an associated cold front sweeps through the region on Wednesday afternoon. With the support of a likely favorable environment in the afternoon, severe thunderstorms on Wednesday will definitely be possible. Some model guidance have already started to hint of the development of something severe, however uncertainty remains as this is still very far out in the forecast. Moving on Thursday and Friday, this aforementioned upper-lvl low will shift over New England and eventually off the coast by the end of the week. Due to the passage of the cold front, highs on Thursday and Friday will be slightly cooler than previous days but will track just along normal for this time of year.
AVIATION /00Z SATURDAY THROUGH WEDNESDAY/
VFR conditions are expected to prevail at KCHS, KJZI, and KSAV through 00z Sunday. Winds will be breezy out of the west or southwest beginning around midday Saturday and continuing through the afternoon. Isolated thunderstorms are possible late in the afternoon or early in the evening, but the chance of direct impacts is too low to include anything in the TAF's at this point.
Extended Aviation Outlook: Some brief flight restrictions could be possible on Sunday afternoon with the showers and thunderstorms. Other than that, VFR conditions will persist.
MARINE
Tonight: Southwest winds 10-15 kt will prevail with seas 2-3 ft.
Saturday through Wednesday: Ahead of the outflow boundary from previous night's weather in the Ohio Valley, south- southwesterly winds could become a bit gusty on Saturday with gusts approaching 25 kts in the afternoon. However, this remains under Small Craft Advisory thresholds. Afterwards, Sunday through Tuesday, high pressure will dominate over the Atlantic waters and result in relatively calm southerly winds with an increase in winds each afternoon associated with the seabreeze.
Moving on to Wednesday, a strong cold front is expected to pass over the marine waters in the afternoon. Severe thunderstorms may develop along this cold front and result in wind gusts well over 25 kts. Generally seas will be 2 to 3 ft, then 3 to 4 ft Wednesday. Small Craft Advisories will likely be needed for Wednesday, however holding off for now until more guidance comes in for this.
CLIMATE
The high temperature for today at KCHS is 94, which ties the daily record high for the date.
