January 11 Spotty Snow Arrived With Arctic Air And Watching Weekend Coastal

Tuesday January 11 2022

You may want to allow for some extra time this morning… The arctic air itself is enough to prompt warming up a vehicle before driving. There has also been spotty snow showers that in some lucky areas produced a coating of snow. This accounts for 10% of the region, but has included downtown Baltimore, Germantown, and others you might encounter on your commute.

In this report: We will look at the arctic air returning at the end of the week, and a southern snowstorm that may try to turn up the coast. It will be close enough to pay close attention to Sunday night and Monday morning.

Radar Snapshot

This was the view over Baltimore at 4:40 AM. Note that it was heavy in spots, and a few blocks away there was nothing.

*I did have flurries in my forecast yesterday when I showed the vorticity with the arctic front. This is a little more robust for some.

Snow Squall Video

Scott Wycoff from WBAL Radio tweeted this scene of the snow squall.

Wow! Check out my @wbalradio video as it’s snowing to beat the band downtown here at the Convention Center as a quick moving snow squall moves through the city! @AvaWBAL @JohnPattiWBAL @WBALPhil @TonyWBALTraffic Lasted for about 15 minutes, putting down a light dusting on roads pic.twitter.com/1PuamNqv66

Radar Loop: 4:15 AM to 6 AM

This snow cluster tracked from southern PA to Kent Island and Easton.

It pulsed , so only about 10% impacted. Noteworthy as you might have a light coating of snow on your route.

Next Monday

The Polar Vortex will be returning to the conversation. It will drop south of Hudson Bay in Canada and send more arctic air next week.

This will support coastal storms… but will they be close to us?

GFS Model:Weekend Storm Animation

A weak system that might bring flurries or light snow Saturday night… Then pushed off the coast. This model actually performed best over the last 10 days.

Snapshots: Monday Morning

GFS:

This is now showing the impact of snow in Maryland with heavy snow on Delmarva.

European Model:

This suppresses that shortwave wall south and off the coast with little development.

Definitely NOT in agreement.

7 Day Forecast

Focus on reinforcing shots of arctic air, and more on the way.

It is still out of range for confidence and with lack of agreement that Sunday-Monday storm is in ‘worth watching’ mode. Not a promise at all for now.
