This may come as a surprise, but there will be some light snow in our area tonight. I was in holiday mode and didn’t see anything major, but there is a piece of energy in the jet stream that is going to peak out overhead overnight.  This is a light snow event, but in the arctic air, the flakes will stick and may lead to slick roads in the morning.

The main area will include Frederick, metro Washington, Annapolis, Baltimore, and up to York and Lancaster in PA. This will be a light, fluffy snow that can blow around easily. The chance is mainly a dusting to 1 inch with some variation across the area. This is just under the criteria for an official Advisory, but even the National Weather Serve put out a special statement agreeing on this as a travel hazard.

Here’s the quick look:

Doppler Radar Loop

This is not very impressive, but that band of snow in central Missouri, southern Illinois, Indiana, and Ohio is what is heading our way.

Jet Streak

This fast moving wind funnel in the jet stream is what will be moving over us overnight and Wednesday morning. This jet streak will help enhance the light band of snow after midnight and into Wednesday morning.

Cold Air: Temperatures at 8 AM

This will translate to light fluffy snow with maximum ratios and stickage.


Snow Potential By 8 AM

Most areas get a dusting of light and fluffy snow. Up to 1 inch in spots. The better chance for 1 to 2 inches will be west of Washington in Montgomery Co and northern Virginia.
