Euro has us in the game for weekend tracking. Ice storm right now though.

What would it take to get that precip shield to expand/strengthen? That seems to be what's keeping this from being great everywhere per the Euro - not that it isn't good already. Edit: was looking at 10:1, kuchera looks much better, disregard!

Euro looks like it wants to merge the events into one marathon.

Don't forget the CMC is coming in now too. Surface looks warmer leading in to Thursday so far. More of a SE ridge.

1049 High on the plains as the ice storm rolls through.

Ice storm... but we're getting there. Give it a few more runs and let's see where it goes. Thursday started as an ice event and it's a lot better now.

Cold air, meet gulf moisture.

Doesn't quite capture every last little bit of snow in the eastern part of the forum, but the GFS thru Thursday looks like a good tick in our favor. Give us one or two similar ticks and most of us should be in a good spot, but it's gonna be a nail biter somewhere regardless. Edit: a few more inches to come on Friday.

SW winds at 850 look weaker on the GFS at hour 60 so that's better, and temps look better at that layer. Precip is further south. Could be a good adjustment.

My biggest worry at the moment isn't south/north but rather lackluster rates and dry slotting like we saw in the thump two weeks ago. If that happens, then we need to hope the Friday shot some of the models like works out, and we've seemed to do poorly in the back half of our storms lately. Would much rather just have a stronger thump than rely on a departing hit. But we're well out of the range where we'll be able to pick out specific regions of lackluster precip so while it's my biggest worry, it's still a small worry. Only really based on how prior storms have gone this winter.

Bet the national blend of models looks pretty, pretty good right now for central MD. Pretty much right in the middle of all the big models.

Yeah the models have been flirting with some big moisture coming up from the gulf for a bit and it has piqued my interest for sure over the past couple days paired with the cold coming. Classic case of give me the ingredients and let the details work themselves out.

UKMET onboard for some thump on Thursday. Big euro run coming up, would be a pretty strong group of models onboard if it joins in.

Changeover complete at Patterson park, all snow right now, but flakes could maybe get better as things go on. No accumulation so far.

I'm very intrigued by next weekend. A ton of cold on the GFS in particular and something maybe coming up out of the Gulf after the midweek event. Canadian and Euro ops aren't as on board with the cold and keep it out west, especially the Canadian, but their ensembles are much more favorable to it. H5 look needs a lot of work, but maybe there's time.

Euro is a decent thump of 2-4 inches 10:1 then ice, then dry slot. Maybe if it's as cold as advertised for that thump, ratios could improve.

CMC was a tick NW but pretty much the same. Also drier; gotta be in the heavy bands to get much.

So we're riding the NAM and Euro it seems. And the HRDPS I suppose. Really need the euro at 12z to hold firm with its call; more ticks lower on QPF would have us knocking on slush territory. I forget who said it, but one of the mets mentioned the 12k NAM and 3k NAM difference a day or so ago was worth paying attention to, as the 12k was much less amped and could signify something to watch since the 3k likes to overamp. Looking like a great call.

So this is late, but seeing as the 12z should start rolling in soon, here's the 00z href snowfall mean and max to compare. I only link the max to demonstrate the dueling ideas of where the heaviest snow falls; do not think you're going to get those totals. You've got one camp rushing through Eastern Shore/DE and another going right along I-95. It'll be interesting to see how that pair of strips evolves in the 12z run. I'm also not sure what ratio this uses, but probably just 10:1, so adjust down mentally as needed.

Just saw the QPF, definitely one of the more confusing runs I've seen. It looked anemic for a while and then it just decides to drop a ball of moisture right over central MD and the eastern shore. I retract my complaint!

Still in business then. Hopefully juices up a bit more though, don't think there's as good a chance of death banding in there if this verifies. Wonder how the nest will compare.

Much less precipitation, that shield needs to juice up in the next few panels...

Yeah I'm not putting much stock into the actual amount it moved NW, just that it did at all. That would be heartbreaking...

SREF has its issues as always, but from a trend point of view, it was further NW at 21z. Precursor to a NAM move?

And here's what NASA has to say about things (0z, 12z not out yet, I have no idea about any characteristics of this model whatsoever, just saw Levi from TT talking about its v2 or something on twitter recently)
