All Activity

woah! pretty heavy snow!

Several years ago HM did a write up on this. There is a SOI correlation, but it’s during El Niños only. As I’m sure you already know, the STJ is driven by thunderstorms in the tropics and the polar jet is driven by temperature contrasts. -SOI enhances Nino related thunderstorm activity in the tropics and subsequently strengthens the STJ, which is already beefed up by the standing wave El Niño convection on the equator. When there is a big drop in the SOI, the southern stream gets enhanced and the chances for east coast storm activity goes way up afterwards. This does not apply during La Nina’s. Many years ago, JB decided to incorrectly apply SOI drops to corresponding to STJ/southern stream enhancement, east coast storms and arctic outbreaks during La Nina’s and it was taken to be fact by the weenies and I guess even by some mets….

I was more referring to the Maryland side of the border. It was modeled to approach an inch near Baltimore when I checked last night yet the closest county to do anything is AA. Not even Howard announced anything and they were slated to get more than Baltimore.

Trashcans are topped here in the lowlands. I'm glad I moved back to AA County from Carroll. That place is horrible at snow lol

Light snow 29

Good morning! I woke up to a dusting here in McLean. Lets see how this goes.

Steady light snow. Looks good for a few hours.

Light snow but with poor snow growth

Gotta figure many places will cancel. LoCo is on 2-hour delay but said "stay tuned". Based on history I bet they'll cancel. Haven't looked at the roads yet but there's lots on the ground and it's snowing now, and it's cold enough the roads won't melt easy.

Light snow in silver spring.

So looks like the closing/delay list has taken its final form then? I’m wondering how many students are going to suddenly feel sick today?

This one is a next’er up here. Radar looks good for RT 50 south.

Light snow at 28 degrees, let’s see what we can do here.

9° here!

What I thought you moved to Aldie

I think buses are already rolling. Need some rates…my snow is subliming before 2 snowflakes can pile on top of each other.

What’s the cut off for them to make a call?

Nada in New Windsor, Carroll County. 00z IAD sounding was a red flag for the northern crew.

a dusting with light snow.

2F here. By far the coldest of the season.

Heading to Orangetheory, hope to come out to a winter wonderland.

7F here just before dawn.

Just need enough to justify my telework. I’m counting on you lol

Virga weeeeeeeeeeeee

Radar looks to be lighting up a bit. Let’s see what we can do for a few hours.
