Good Saturday to one and all. Stop me if you’ve heard this before… But, it’s another brutally cold day out there across the Commonwealth. The good news is, the bitter cold is about to break. The bad news is, we have a wintry mix coming behind it.

We start things out with readings of -5 to + in most areas, with a wind chill pushing -10 for some. Afternoon readings top out in the upper teens and low 20s with a mostly sunny sky.

Temps tonight into Sunday morning should manage to hit the single digits again in the central and east.

That will make it 7 straight days of single digits or colder to begin the new year. Take a step back and just appreciate how amazingly cold this pattern has been. It’s historic.

Moisture begins to stream in from west to east late Sunday into Sunday night. With low-level arctic air in place, frozen precipitation looks like a good bet. Throw in a frozen ground, and you have the recipe for nasty travel conditions to develop.

That’s especially true when seeing the Monday morning temps from the NAM…

Don’t get caught up with the precipitation types showing up on the models. They will struggle mightily in this setup. As I’ve mentioned many times before, even if air temps go above freezing, the ground is frozen, so you will get roads to ice up.

Let’s keep this rolling for a little longer…

 I can’t speak to 100% specifics of each precipitation type where you live, but the icy road potential is pretty darn high, regardless.

That system moves away quickly, with a surge of mild temperatures getting in here later Wednesday and Thursday. The GFS for Thursday…

That’s ahead of a powerful cold front, bringing this about a day later…

Rain and some thunder will be possible ahead of that front, with frozen precipitation showing up just behind it…

That setup should be able to fuel a low pressure along the front, bringing the potential for a bigger system by late Friday or Saturday.

I will have updates later today, so check back.

Make it a good one and take care.
