Showers and thunderstorms associated with a cold front will move through the area tonight, bringing with it some brief heavy rain and perhaps the risk for a damaging wind gust or two through early Thursday morning. This is not the high-end risk we have seen in a few times in the past few weeks — not by a long shot! — but you may want to have a flashlight at bedside just in case of a brief power outage overnight as some sporadic wind damage does appear possible.
We’ll broach 80° tomorrow despite increasing cloud cover as a cold front approaches the area from the west with our main rain chance this week. There is a small chance that showers could develop near the coast in the late afternoon hours, but the best rain chances arrive overnight into Thursday morning with a band of showers and thunderstorms. Fortunately, severe weather is looking rather unlikely, though a few strong wind gusts will be possible. Will have more on this rain threat tomorrow as timings become more apparent — stay tuned.
Breezes will turn southerly on Tuesday as high pressure slips offshore, allowing temperatures to rise near to near 80° in the afternoon under mostly sunny skies. Humidity will be a touch higher, but you probably won’t notice — should be another really nice day. Try to enjoy!
Tuesday will be a mostly sunny day in-between cold fronts. Winds will turn from the south to the southwest throughout the day, allowing temperatures to swing from the mid-50s to around 80° in the afternoon. No weather hazards to speak of for Tuesday, thankfully — business as “usual” (by 2020 standards, anyway).
Another rough morning is in the cards with a squall line expected to move through the area. Said squall line may produce damaging wind gusts, hail, and tornadoes — a couple of which may become strong.
The squall line should be through the area by 11am, according to the latest NWS briefing. This seems reasonable, and I wouldn’t be surprised if it was out of here a lot sooner than that.
Some overnight severe weather is not out of the cards, but it increasingly appears that the threat for severe weather in the Tri-County area will arrive around sunrise. Still, don’t go to bed without having weather warnings that can wake you.
Flooding may be a concern, particularly around the 7:12am high tide.
Once the squall line clears the area, winds will shift northwest and we should see at least some partial breaks in the clouds before the day is over.
Our active spring severe weather season looks to continue Sunday night into Monday morning, as a potent storm system traverses a ripe, well-sheared airmass in the Southeast with the potential for tornadoes and damaging winds.
After this morning’s deluge and a very chilly afternoon, Thursday’s going to be pretty great, weather-wise — much more sunshine, low humidity, and highs around 70 in the afternoon as surface high pressure settles in over much of the eastern half of the country. The normal high for April 16 is 77°, so this will run several degrees below normal. Most importantly, we’ll get a chance to dry out after a couple rounds of rather heavy rain. Try to enjoy it as best you can in these circumstances!
Get ready for another big temperature swing for Wednesday. We’ll have some showers in the area during the morning as low pressure shifts offshore, pushing a stalled front near the coast further eastward. As that happens, cool high pressure will build in, keeping temperatures well below normal for mid-April in the mid-60s — legit late-season hoodie weather for your walk around the neighborhood or grocery runs. Expect temperatures to continue below normal through the end of the work week.
No, you suddenly didn’t wake up in June (though we would all understand if you felt that way): Temperatures will approach record levels on Thursday ahead of an oncoming cold front. Westerly winds will usher in more drier air, thankfully, so the humidity won’t be terrible as we approach our record high of 90° for April 9.
There is a small possibility that the remnants of a thunderstorm complex coming in from the northwest could bring showers to the area early Thursday. The official NWS forecast remains dry, highlighting only about a 10% chance of rain in the Charleston metro. Further west toward I-95, chances are marginally higher. Trends will be watched, but odds point to dry conditions in the short-term models.
Of note: A statewide burn ban is in effect, and weather conditions particularly in Berkeley and Dorchester counties will become prone to wildfire Thursday afternoon. Please, please, please do not burn — let’s not give our first responders anything else to deal with.
We’ve got another warm day on tap Tuesday as temperatures top out in the mid-80s under partly cloudy skies. We’ll want to keep an eye on the skies in the afternoon and early evening hours for the potential for a few storms to work their way into the area; one or two of these could produce some strong winds and maybe some hail. Otherwise, we continue late-spring/early-summer-like weather.
Once again, we will need to watch for the potential for minor tidal flooding around times of high tide Tuesday (8:02am and 8:33pm). Keep an ear out for Coastal Flood Advisories if you have any essential travel tomorrow. (Otherwise, stay home.)
