Thursday: A little cooler as high pressure settles in

/ January 1, 2025 at 10:30 PM

High pressure will be settling into the area overnight into Thursday, and this will drive a mostly sunny but seasonably cool day across the area. Expect lows in the mid-30s (with perhaps some freezing values in rural locations) to start Thursday, warming to just the mid-50s in the afternoon despite all the sunshine. Generally, temperatures will be running a few degrees below early January normals (normal high of 60°, normal low of 39°), but nothing terribly out of bounds.

Start of 2025: Seasonably cool, generally quiet

/ December 31, 2024 at 7:02 PM

2025 gets off to a seasonably cool start in the wake of a cold front that will be coming through overnight tonight. Lows on Wednesday bottom out in the mid-40s, but ongoing cool advection will keep highs around 60° or so despite just about full sunshine during the day. Thursday runs a little cooler, starting in the mid-30s and warming to just the mid-50s in the afternoon, and Friday is essentially a carbon copy, with lows in the mid-30s once again yielding to highs in the mid-50s in the afternoon with plenty of sunshine. Overall, the start to the year is quiet, with the first rain chance of the year coming up on Monday.

Have a happy and safe New Year’s celebration. Here’s to you and yours in 2025!

Clouds and showers to continue for a fair bit of Friday; tapering late

/ at 9:13 AM

A coastal trough continues to affect the area today, with showers overrunning the top of a cold high pressure wedge that has kept temperatures pretty constantly in the mid-40s for the past couple days now. We should see that trough lift inland later today, though, as high pressure anchored to the northeast weakens and steps aside. This will help break the wedge and allow a little warmer air to move in, especially later, though we will stay somewhat cool with highs in the upper 50s. The risk for showers should also diminish with time today, though we can expect off and on rain for much of it.

Christmas forecast: Rain tapers Tuesday morning, then mostly quiet and seasonable

/ December 24, 2024 at 1:40 AM

We get Christmas Eve off to a chilly and wet start on Tuesday, but showers will diminish throughout the day as low pressure pulls away from the area. Temperatures bottom out in the upper 30s to around 40°, with wind chills making it feel even cooler. As the day goes on, temperatures will head into the low to mid-50s in the afternoon with some breaks in the clouds developing.

Christmas morning will start out seasonably cool, with lows once again topping out in the upper 30s to around 40°. It’ll be a bit warmer of a day with more sunshine expected; highs should peak around 60° in the afternoon. Northeasterly winds will be a touch on the breezy side, but otherwise, no concerns for Christmas Day.

I hope you have a happy and safe holiday!

The week ahead: A seasonable Christmas with a few shower chances at times

/ December 22, 2024 at 11:13 PM

We start the holiday week off on a chilly note. Expect subfreezing temperatures inland of the coast Monday morning, with wind chills in the low 20s expected. We could even see those wind chills drop below 20° further inland, prompting a Cold Weather Advisory for inland Berkeley and Dorchester counties from 4-9am. Cloud cover will build across the area throughout the day Monday, with even a stray shower possible at the coast. Highs will remain well below normal, with low 50s expected at best.
