Snow in Ellicott City along Rt 40 per Mrs. WxUSAF. Should be here soon. -
When it was more of a Black Friday threat, we had more time to get a cold airmass in place. Now it’s only like 24-36 hours behind the weak cold front next Tuesday.
-
I mean, sure if you want to go that route. Or you can recall it’s November with a marginal airmass leading in?
-
That front edge looks nice for you

34/25

Euro takes a really nice track actually. One that would be nearly perfect for snow in another few weeks. Just doesn’t have enough cold air to work with.
-
Congrats on your winter precip for the 2024-25 season!
-
It’s quite possible. Not going to have a ridge from Baja to Siberia all winter. Hopefully we get western ridging to reload throughout the winter. But I’d bet my lunch we get some torch periods.

Damn…3k NAM is 34ish with snow for MBY. Hmmm
-
Lock it up!

Longwave pattern continues to look good through the end of the 12z ensemble runs with BN temps. No defined storm periods after thanksgiving itself, but it doesn’t look bone dry. Shift in phase of the NAO from - to + could be an indicator. That seems to happen late in the runs (mid-late first week of December). GEPS actually has a coastal on D15.

Totally realistic 10:1 euro snow map gives @mappy and @psuhoffman over 3”. 12z runs seemed to have moved start time back up to 12-14z, so better temps to work with.

Not sure how to link Bluesky posts, but this from Pete is fun @wxmvpete

At 33 you could accumulate if it comes down heavily for a time. Measure immediately! But the 36-39 IMBY is 100% white rain.
-
Yeah. The later start isn’t what we want I think. But freezing level is still around 950mb for most of central MD, so that should support snow reaching the ground in heavier bursts?

Thunder and lightning in Columbia

18z is way faster than 12z gfs or euro, which is not what we'd want. Need time to get that cold HP moving into southern Ontario area. Verbatim gives some widespread light snow with the upper low on Black Friday though.

Tracking flurries and @psuhoffman posting novels in the mid range thread. We’re so back baby
-
18z hrrrr also happy for happy hour
-
You getting 1” by December 1st gives us a 64.76525% chance of an acceptable winter, right??
-
That’s a really cold GEFS run. BN from next Wednesday through the end of the run.

Good 12z suite for first flakes for many in central/northern MD and NoVA and slushy accumulations for favored cold spots. Positive change seems to be due to the low being farther southwest and closer to us. Hence more directly in the cold core of the low with heavier precipitation. Also helps that precipitation comes in right around 12-14z when temps are coldest.

I’m so excited for just any kind of real weather. Been a pretty boring stretch!
