Coolest day of the week for Tuesday, then we warm back up

/ November 23, 2020 at 9:11 PM

Cool high pressure will be in control of Tuesday’s weather, with highs topping out in the low to mid-60s across the area under mostly sunny skies. A breeze out of the east will keep it feeling a little more brisk during the day as well. Overall, not too shabby with temperatures running a touch below normal.

Clouds will be on the increase Tuesday evening into Wednesday as our next storm system approaches the area, first bringing a warmup and then possibly some Thanksgiving rain.

Thanksgiving week: Quick cooldown, then warm temperatures

/ November 22, 2020 at 7:10 PM

Aside from Monday evening into Tuesday, Thanksgiving week will shape up a bit on the warm side, with a few showers for Thanksgiving Day possible.

Overall, the pattern will be pretty progressive this week. We’ll start the week with a cold front swinging through during the day Monday. This will knock temperatures back into the low 40s by Tuesday morning, with highs only reaching the mid-60s during the day. High pressure quickly shifts eastward, though, allowing for temperatures to moderate (and clouds to increase) ahead of another front Wednesday. The next front looks to swing through Thursday into Friday, and this is where we may see a few showers develop. (Right now, chances are low.) Temperatures will then level off a little lower, with perhaps some rain chances toward the end of the weekend depending on the forward speed of another storm system.

Watch out for a few showers on Sunday

/ November 21, 2020 at 9:14 PM

As high pressure to the northeast weakens and moves away, a trough of low pressure along the coast will move inland, and along with it will come a chance of showers for Sunday. The best risk for showers will occur in the afternoon. Not everyone will see rain and it won’t rain all day — just keep an eye to the sky and be ready to deploy the rain gear if you need to. Temperatures will remain mild (but not horribly so) for this time of year with highs topping out in the low 70s.

Warming trend for Friday and the weekend

/ November 19, 2020 at 6:05 PM

After a couple chilly days, the 70s return to the weather picture starting Friday and through the weekend. The warming trend will be very gradual, but expect Friday to start in the upper 40s, with low 50s for Saturday and perhaps mid-50s for Sunday. We’ll see a little more cloud cover than we have in previous days, but overall the weather should remain quite pleasant for the weekend before Thanksgiving.

Frosty start to Thursday gives way to a comfortable afternoon

/ November 18, 2020 at 10:15 PM

Clear skies and light winds will allow temperatures to drop into the upper 30s overnight, likely causing some frost to develop away from the coast. The National Weather Service has issued a Frost Advisory that includes Berkeley and Dorchester counties for early Thursday. Make sure you cover up your plants and have your pets in a warm place tonight.

Once we get clear of the frost, we’ve got a pretty solid November day ahead with highs topping out in the low 60s under mostly sunny skies and a bit of a northerly to northeasterly breeze.

Reinforcing shot of cold air to bring sweater weather on Wednesday

/ November 17, 2020 at 5:59 PM

Get your sweaters ready — Wednesday is going to be a chilly one. A dry cold front featuring a reinforcing shot of cold air will swing through the area tonight. By tomorrow morning, winds will be back out of the north and a little breezy — lows in the low 40s may feel closer to the mid-30s when factoring the wind in. Despite full sunshine, temperatures will only rise into the mid-50s given continued cold advection into the area.

As high pressure slips overhead Wednesday night, winds will calm and skies will remain clear, allowing for excellent radiational cooling conditions. We may be contending with some frost as we get into overnight Wednesday/early Thursday morning, especially in the inland tier of counties. Keep an ear out for a possible Frost Advisory from the National Weather Service, and be ready to ensure plants, pets, and people are protected. (Pipes will be okay — not expecting a freeze just yet.)

Picture-perfect Tuesday ahead

/ November 16, 2020 at 9:09 PM

High pressure will remain solidly in control of our weather Tuesday with another beautiful mid-November day ahead. Highs will top out in the upper 60s after starting out in the low 40s (and maybe the upper 30s inland) with nary a cloud in sight. This will put temperatures right around, if not a little bit below, normal for mid-November.

The week ahead: Drying out and cooling off

/ November 15, 2020 at 9:49 PM

A cold front is swinging through the Southeast Sunday evening, which will bring a stop to the ridiculously humid weather we’ve been experiencing this past week. Temperatures will be right around normal to start the week under full sunshine. A reinforcing shot of cool air on Wednesday will knock us firmly into sweater weather territory, with moderating temperatures into the 70s for the weekend. The week looks to remain rain-free, which will be awfully nice after the tropical soaking we took last week.

Friday and the weekend: Exit humidity, enter tidal flooding

/ November 12, 2020 at 10:35 PM

After a soggy day that turned quite breezy thanks to Tropical Storm Eta and a cold front, we will begin to see temperatures more in line with what we expect from Fall (but still above normal). Clouds will scour out on Friday, leaving a fairly lovely day with highs topping out in the mid-70s. Saturday will be quite refreshing in comparison to where we have been; we’ll start the day in the mid-50s and head up to around 72° under mostly sunny skies. A cold front approaches the area on Sunday, which will kick up a little compressional heating ahead of it and send highs back toward 80° (albeit with less humidity). A few showers will be possible ahead of the front. Sunday’s front is the one that is going to knock us back into temperatures more in line with November norms as we get into next week.

Soggy Thursday coming with the potential for flooding

/ November 11, 2020 at 9:45 PM

Some pretty heavy rain for any time of year, much less November, is in store for Thursday. Deep tropical moisture will continue to blanket the area ahead of a cold front. At the same time, Tropical Storm Eta will move across northern Florida and into the Atlantic, weakening while undergoing a post-tropical transition. Be ready for the potential for flooding due to heavy rain, especially around times of high tide (4:54am, 5:10pm). Some tidal flooding cannot be ruled out, either.

Temperatures are just not going to move much tomorrow with rain expected to be in place for a fair bit of the day. Highs will top out in the upper 70s after a low in the mid-70s, which would absolutely destroy the record high minimum temperature of 68° set in 1975. Our lows have been rewriting the record books for the last few days due to such abnormal warmth. (A normal November low based on 1981-2010 climatology is 48°!) Fortunately, there is some relief in sight with the cold front.
