Much quieter weather today as Isaias has long since departed the Charleston area. Temperatures top out in the low 90s, but the humidity will feel closer to the low 100s. There is a slight chance of an isolated PM shower or thunderstorm on the seabreeze as it advances inland this afternoon. A trough of low pressure aloft will keep things a little stormy each afternoon as we go into the rest of the week.

We have been in quite the cool spell this week as an upper-level low pressure system in concert with a stalled front have kept clouds and showers in the forecast. The cool temperatures have been rather remarkable for June, with legitimate hoodie weather the past couple days as several record low maximum temperatures were achieved both at Charleston International Airport and downtown Charleston. Summer’s coming back, though…

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).

Here’s the lowdown on Monday:

• 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.

I will have a new live blog in the morning.

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.
