Clouds will increase overnight into Tuesday morning, giving the day a mostly cloudy look with just a few peeks of sun possible in the morning and early afternoon hours. It’ll feel noticeably colder in the wake of today’s cold front — highs should only top out in the mid-50s.

As low pressure organizes off the coast and begins to move northward, some overrunning should take place, generating scattered light showers across the area by mid-afternoon. Showers will continue into the evening, with the best rain chances arriving with the cold front Wednesday.

After what ended up being a fairly nice weekend, we have one more day in the 70s before we’re back to more seasonable — if not a bit below-normal — temperatures across the Lowcountry for the last full week before Christmas. (Yes, it’s almost Christmas. It’s shocking to me, too.)

A cold front will swing through Monday, bringing a chance of showers to the area generally from mid-morning to early afternoon. High pressure will wedge in behind it, cooling us off but also keeping some cloud cover around for Tuesday. Another storm system will ride up the coast Wednesday, potentially turning into a decent nor’easter for the Mid-Atlantic states and New England. We’ll see mostly sunny skies with continued chilly temperatures to close out the work week. Clouds increase for the weekend, with perhaps some showers on Sunday.

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.

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.)

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.

Expect a bit more in the way of cloud cover and showers for Tuesday as a moisture plume courtesy of Tropical Storm Eta begins to spread northward. Temperatures will remain rather warm for this time of year. We’ll start the day in the upper 60s to low 70s (especially near the coast). Temperatures will top out in the low 80s, with periods of cooling where showers develop. Shower chances will continue to ramp up with time on Tuesday, with thunderstorms becoming likely as we head into Wednesday.

Temperatures will head back above normal this week with shower chances coming back into the picture starting Tuesday. Showers will be isolated to scattered at best for most of the week as a coastal trough persists. Onshore flow will keep dewpoints up, making for a warm and humid mid-to-late October week. Expect highs in the 80s just about every day with lows in the mid-60s. (Closer to the coast, take a couple degrees off the high and add it to the low.)

Astronomical influences and onshore winds will send water levels in Charleston Harbor well into flood stage at times of high tide this weekend. Moderate to major coastal flooding (8.0′ MLLW) will be possible with each morning high tide through at least Monday, while minor flooding is expected with each evening high tide. Road closures will be possible at times of high tide, with some routes becoming temporarily cut off due to salt water inundation.

If you step outside this morning, you’ll notice a welcome lack of humidity as high pressure wedges in from the north, drying out the air at the surface (though cloud cover will remain in place today thanks to some moisture trapped between 4-6,000 feet as well as some upper-level energy that will stir up high cloud cover later today). Dewpoints this morning were running well into the low 60s, with even a reading of 59° at Charleston International Airport at 8am.

Unfortunately, this surge of Fall weather will also come with several rounds of major coastal flooding this weekend into early next week.

So the first thing you will undoubtedly notice in the seven-day is that it is largely bereft of 90s (save for Monday). You may also notice a high of 79° for Sunday. Yes, that’s out there a ways and could still be tweaked upward, but it is just refreshing to see 70s for highs somewhere in the forecast. We’ll need to deal with some rain and coastal flooding to get here, though.
