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

/ 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!
