No severe weather was reported in the Charleston area today, though golf-ball-size hail did fall in Sun City (west of Hilton Head along Highway 278). See today’s storm reports as relayed by the National Weather Service in Charleston.
A mostly calm night is ahead for us, though some showers associated with an expected area of low pressure offshore may bring some rainfall overnight. We could also see some dense fog form; no advisories have been posted but if dense fog becomes widespread, a Dense Fog Advisory will be issued. Keep an eye on @chswx on Twitter tonight and tomorrow in case an advisory is posted. Temperatures will fall generally around 60-63 in the Charleston area (warmer near the coast).
Scattered thunderstorms are again possible tomorrow afternoon; highs around 76-80 (warmest inland). Don’t think severe storms will be an issue for us but I’ll keep an eye on it.
Looks a lot like summer out there today…

Expect thunderstorm coverage to increase this afternoon. Could see some hail and strong winds from the strongest storms. Will keep you advised over on Twitter and on the blog as time permits.
We’re in a break in the rain for right now but expect showers and storms to redevelop this afternoon, possibly just in time for the evening rush. Highs in the mid-70s.
Clouds and a chill remain in the air as the high pressure wedge from yesterday hangs in there. Cloudiness will erode and temperatures will get slightly warmer today than yesterday, with highs around 73; the normal high temperature for this date is 79. We’ll get back there tomorrow with no rain expected through Thursday, when showers and thunderstorms will arrive ahead of a front.
Noon temperature check: 62 at the airport, 58 downtown, 59 in Mt. Pleasant, 61 in Summerville. Temperatures are still expected reach upper 60s inland; a little lower near the coast.
The pressure gradient that made it awfully windy yesterday is forecast to back off a little, but not by much: we’re still looking at a rather breezy day with 20-25 MPH winds near the coast and gusts to near 40 MPH in the morning (wind advisory has been extended through noon), though I don’t expect a repeat of the 60+ MPH gusts measured on the Ravenel yesterday!
The other story is the chill in the air. NWS is expecting temperatures only in the upper 60s; this is 10+ degrees below normal for April 22.
We should get some sun in by afternoon but partly cloudy skies will remain the rule under the influence of a an unseasonably strong high pressure wedge (a phenomenon with high pressure that sets up to the northeast of the area; it “wedges” between the Atlantic waters and the Appalachian Mountains, helping keep cooler Atlantic air trapped near the surface). No rain is expected aside from an outside shot at a shower near the coast (though those chances will taper off by afternoon as well).
We’ll get a little warmer on Tuesday and near normal on Wednesday. Hang in there!
Updated at 8:35 AM 4/22/2013 for the extension of the wind advisory.
74 MPH wind gust reported at the Ravenel Bridge just after midnight. That’s hurricane force, folks!
Update as of 11:45 AM: The wind advisory has been canceled. High surf and rip currents still an issue through this evening.
The National Weather Service continues a wind advisory until noon for Charleston County and southern Berkeley County (Daniel Island and the ports). Wind gusts over 40 MPH may be possible with higher gusts on elevated surfaces.
In addition to the wind advisory, hazardous surf will continue to be a factor through noon Monday; dangerous rip currents will continue to be possible through 8PM. If the beach is in your plans — and with that kind of wind, it’d be awfully unpleasant — be advised of dangerous conditions in the water.
A strong wedge of high pressure building down from the northeast is interacting with the front that set our temperatures back to March normals; the resulting pressure gradient is making for some incredibly gusty winds tonight, with gusts up to 68 MPH (!!!) on the Ravenel Bridge. Some more gusts:
- 47 MPH at the Isle of Palms pier
- 41 MPH on the Don Holt Bridge
- 40 MPH at Folly Beach & the Charleston Executive Airport on Johns Island
