A strong cold front will bring about the first freeze of the season overnight Monday into Tuesday as a highly anomalous intrusion of Arctic air pushes southward.

Weekend forecast: Spring-like warmth before a wintry chill

/ November 7, 2025 at 10:45 PM

A couple more warm days lie ahead before the coldest airmass of the season crashes into the area next week. Saturday will generally feature temperatures in the upper 70s after starting the day near 60°. We’ll keep a few clouds around, but the risk for any rainfall should be very low.

A strong front approaches the area Sunday, and there’s a chance that some showers and maybe a thunderstorm could move through in advance, but the risk will be diminishing as the front pushes eastward as moisture doesn’t look to be in abundance. Temperatures Sunday peak near 80° after starting in the low 60s.

Tuesday: Another sunny and seasonable day

/ November 3, 2025 at 8:02 PM

Plenty of sunshine will continue on Tuesday as high pressure builds across the area from the west, keeping northeasterly flow in place which will keep temperatures on the cool side of normal and also help to elevate the morning high tide into minor flood stage. We’ll start the day in the mid-40s, warming to the upper 60s in the afternoon, which will feel quite comfortable with the sun out. The aforementioned northeasterly winds will run generally in the 5-10 MPH range, which will be enough of a breeze to make it feel a little cooler in the shade.

As mentioned, some coastal flooding will be possible between 5-8am as water levels peak in minor flood stage (7-7.2′) with the 6:11 am high tide. This may have limited impacts in the most vulnerable areas of the peninsula, primarily around the Hagood/Fishburne intersection as well as possibly on parts of Lockwood. Be ready to reroute around any closures.

The week ahead looks generally quiet and increasingly warm, especially as we get into late week and the first part of the weekend, but nothing too out of bounds for early November. Coastal flooding will become an issue beginning Tuesday as favorable winds and the highest astronomical tides of the season coincide, though.

We’ll then warm to the upper 60s in the afternoon with plenty of sunshine to be had as high pressure slides overhead.
