We’re in for another gray, rainy day on Friday as low pressure develops and slides south of the area along a stalled front. The best chance of rain will be during the morning hours before tapering off in the afternoon. Temperatures will top out in the upper 50s.
It gets better, though. Expect skies to clear by Saturday morning with a northeast breeze helping keep temperatures in the mid-50s despite all the sunshine. We’ll start Sunday in the mid-30s before temperatures head up to near 60° under increasing cloud cover. If I had to pick, I’d probably choose Saturday for more abundant sunshine, but Sunday won’t be any slouch either with a little warmer temperatures in the afternoon.
Clouds and eventually showers will return to the weather picture during the day tomorrow as a cold front approaches the area. Temperatures will get to the low to mid-60s before the front swings through. Winds will also kick up with the frontal passage, so be ready for gusts near 30 MPH through Saturday.
Speaking of Saturday, clouds will be clearing the area, but we will once again turn chilly, with highs only topping out in the low 50s. The aforementioned wind will make it feel even colder, too. Most of us away from the coast will see freezing temperatures Sunday morning (along with mid-20s wind chills). Highs will once again only reach the low 50s in the afternoon despite plentiful sunshine. These temperatures will be the result of a large cold-core upper low that will be swinging through the upper Midwest into the Ohio Valley and eventually New England over the weekend, sending a plunge of rather chilly air all the way south into Florida.
We have a cool and quiet weekend ahead in the Lowcountry. Tonight’s rain will exit the area early Friday morning as a cold front swings through the area, but the storm system’s parent upper low will continue to lumber through North Carolina, potentially spawning scattered showers as the day goes on in our neck of the woods. Rain chances will decrease even further after sunset Friday, leading to a dry weekend.
Temperatures will remain cooler than January normals throughout the weekend, with mid-50s the norm as we sit between the departing low pressure system and high pressure in the upper Midwest. Relatively dry air will keep cloud cover generally thin, especially on Sunday.
Our next storm system arrives Monday as another upper low ushers through a front to start the week.
We’ve got a warmer-than-normal weekend ahead of us as high pressure slips offshore and a cold front approaches from the west.
Friday will remain mostly sunny after some patches of possibly dense fog in the morning. Highs will top out right around 70°, making for a nice afternoon across the area. Similar temperatures are expected Saturday despite more cloud cover. A slight shower chance comes into the forecast late Saturday, continuing into Sunday. Temperatures will top out in the low 70s on Sunday ahead of the cold front.
No washout is expected this weekend — just keep rain gear handy in case a shower comes through. The majority of the rain associated with the front will come through Monday, with the heaviest rains looking to remain to our north.
Mostly sunny skies and warmer temperatures will make for a very nice Thursday across the Lowcountry. Expect temperatures to start out in the upper 30s to low 40s in the morning, followed by highs topping out in the mid-60s — just a touch above normal for December 10.
Friday will see a brief return to the 70s as a cold front approaches the area. Showers look to begin in the afternoon and will continue through the overnight, with the bulk of the rain falling during the late afternoon/evening hours. Rain will taper off overnight as the front moves through, and by sunrise Saturday we should see clearing skies and breezy westerly winds.
The weekend looks nice and sunny, but will be a little chilly. Highs will only get to the low 60s on Saturday in the wake of the front. The cool weather continues on Sunday, with lows in the upper 30s and highs topping out in the upper 50s. This will still run a little below normal for the first weekend of December, but won’t be quite as cold as the airmass we had earlier this week.
Bring in your pets and plants again tonight as temperatures will be headed toward the freezing mark once more, generally along and inland of Highway 17. The freeze won’t be quite as widespread as we saw this morning, but expect temperatures to fall into the 30s close to the coast, including into downtown Charleston.
After the chilly start, temperatures will rebound back into the 60s for the afternoon as winds turn more onshore throughout the day. Expect clouds to increase as well from the west ahead of our next storm system, which brings rain back to the area for Friday.
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.
High pressure ridging overhead is going to keep thunderstorm chances low and temperatures up for Friday and the weekend. Couple that with a side of Saharan dust advecting in from the southwest and we’ll have a few hot, hazy, and humid days ahead. In fact, during the afternoons, heat indices may approach the upper 90s to around 100 at times, so be sure you’re getting hydration if you are outdoors. A stray thunderstorm or two will be possible Friday and Saturday afternoon, with a tighter lid on potential storms for Sunday (as things stand right now, anyway).
Sunsets could be particularly colorful Saturday and Sunday night, as NASA dust modeling suggests peak Saharan dust activity around these times. It remains to be seen what, if any, air quality impacts there will be, but we’ll want to keep an eye on that for sensitive groups, especially with our recent acceleration in coronavirus cases aggravating respiratory matters.
