Severe Thunderstorm Watch has been canceled

UPDATE 11:13 PM: The National Weather Service has canceled the Severe Thunderstorm Watch for the Charleston area. The severe weather threat has diminished for our area.

Earlier this evening, severe thunderstorms hit Berkeley County, dropping half-dollar size hail on Bonneau Beach earlier and knocking down some trees in Cordesville and near Moncks Corner. An amateur radio operator reported power outages lasting over an hour in Cordesville along Highway 402.

If you have any additional reports of severe weather, please post them in the comments with a location and a description and I will forward to the National Weather Service.

Great weather for Saturday; showers and storms possible Sunday

Spring is back for a few more days — gorgeous on this Saturday with highs only to top out around 80 away from the coast. A few thunderstorms will be possible Sunday afternoon and evening as a disturbance aloft swings through, then back to dry weather for much of next week as ridging builds in. We’ll get gradually warmer; NWS has us approaching 90 again by the end of next week.

Today’s the calmest day of the week – watching severe risk Tuesday, especially Wednesday

Another very warm day for late April is upon us with temperatures in the upper 80s expected inland; a couple 90 degree readings wouldn’t be far-fetched either. Closer to the coast, the cooler Atlantic waters will keep temperatures moderated into the upper 70s to low 80s. The seabreeze may kick off a storm or two as well, but most will stay dry. All in all, today will likely be more reminiscent of late May than late April.

This week looks pretty unsettled, with shower and thunderstorm chances ramping up Tuesday-Thursday. We all need to pay attention to Wednesday (and if you’re further inland, Tuesday as well) for the potential for strong to severe thunderstorms. It’s not a bad idea to review your severe weather plan — it is Spring, after all — and make sure your reliable weather sources (NOAA Weather Radio, smartphone app of choice, etc.) are in good working order. More on this later this evening…

Tornado watch no longer in effect

This tornado watch is no longer in effect.

A tornado watch is up until 9PM for the Tri-County area. Right now most of the Tri-County is dry; however, conditions along and ahead of an advancing “wedge front” — the leading edge of a high pressure wedge being re-established inland thanks to rain-cooled air — are becoming increasingly favorable for a few tornadoes along with straight-line damaging winds.

Stay attuned to reliable weather sources such as NOAA Weather Radio, local media, the National Weather Service (http://weather.gov/chs) for updates or possible warnings.

Severe weather risk this afternoon

This morning’s weather data is lending increased confidence to a risk for isolated severe thunderstorms later this afternoon and evening. Damaging straight-line winds will be the main concern, though isolated tornadoes are not out of the question. NWS will have an even better idea once our morning weather balloon is away.

Stay weather-aware this afternoon and be on the lookout for potential severe weather watches or warnings if they are required (gut feeling is that we could be put under a watch at some point later this morning or in the early afternoon).

Remember, social media is great, but should be a supplement to a balanced severe weather information diet. NOAA Weather Radio and these additional tools will help keep you in the loop on this and any other severe weather day.

One more chilly day this week, and then Spring does its thing

The strong cold front, which ultimately failed to yield much if any rain in the area, got through overnight and has cleared the area. No rain expected today — skies will be partly cloudy to sunny — but it will be windy, with gusts possibly reaching 40 MPH at times. Thus, NWS has a Wind Advisory out until 8PM. Use a little caution on the bridges today.

Today will be the chilly outlier in what looks to be a very warm week. Temperatures will only get around 70-72 away from the beaches (where mid-60s seem much more likely). We’ll get into the mid-70s for Monday and then 80s! So many 80s — and so much sun, too! This will actually be a little above normal for the first part of April but after the winter we’ve had, I think we’ll take it.

Next front may become an issue for the first part of the weekend — wait and see on this one. Will know more by mid-week.

Flood advisory until 6:30am for the Charleston metro including downtown

We’re starting the day with a flood advisory for downtown Charleston, James Island, western Mt. Pleasant, and West Ashley as several rounds of heavy rain continue to move through the area. With high tide approaching (7:36 AM), drainage could become an issue. Flood advisory goes until 6:30am. If you see water covering the road, take an alternate route. Expect steady rain to let up by mid-morning as we get between precipitation events.

Slight severe weather risk tomorrow

Rain chances will be with us overnight tonight into tomorrow morning; lows will only fall to the mid-60s.

Tricky forecast for tomorrow — best rain chance is going to be in the afternoon. What we’ll need to watch is whether clouds break and let the sun peek through for any extended period of time ahead of the front — if this happens, we may be dealing with a few severe thunderstorms (with damaging winds the main concern) during the afternoon hours. Make sure you have reliable ways to receive National Weather Service watches and warnings. Facebook is not that venue — start with a NOAA Weather Radio or an alerting smartphone app such as iMap Weather Radio or even any of the local television station apps. (The Weather Channel’s app will push alerts, too.) With any luck, cloud cover will stick around and we won’t have to worry about the severe threat so much, but it’s better to be prepared!

Sunday looks much better — highs around 70 with a drier airmass in place will make for a really beautiful day in the Lowcountry.
