Just checked the euro AI models, they've been windshield wipering the past 3-4 runs. I think the models will need at least a couple of days to get a better handle on this. It may not happen in the next run.
The key thing to watch on the Euro for the next runs is we need the 500mb s/w to dig WEST over Minnesota at valid time 00z Jan 30.
The 12z euro didn't dig that as far west as 6z did, and hence the result. So when watching for trends, watch the 500mb vorticity over the Minnesota/Wisconsin/upper lakes.
So as we can see, there are 3 main scenarios/clusters - 1) way OTS fish storms, no one gets anything except maybe cape cod gets clipped, 2) storm tracks from OBX NNE with some tucks/scrapers, 3) miller B esque storms bombing out too late for us.
Means went east, but there is stronger clustering of SLPs further south just off OBX than the previous run. I'd say its noise at this point and wait until 0z tonight to make any prescriptive statements on where this is going.
Recent storm, we were in the bulls eye or just north of it before the D4 "model reshuffle" (yes I'm coining that phrase). This time let's reshuffle this into us being the bulls eye!
Looks like the trough/sw is backing west, eliminating some OTS possibilities. But we'll just have to see how far west it backs until they hone into something that's close to a solution. The storm yesterday - the NS wave and the phase kept backing west for days, and for a couple days it was at the sweet spot for us, and then it still kept backing west.
DCA 6.8
IAD 7.8
Spotter in Ashburn reported 9.8”, which is consistent with my 9.5” so that’s good to see I’m measuring it right

I wouldn’t sleep on this one. Right now ridge and trough axis too far east, but we said the same thing about today’s threat being too suppressed. Lots of time for things to change for better or worse.
Another inch of sleet had fallen since my last 8.5” measurement. Back edge about to clear my area. Calling it 9.5” total, 5.5” snow 4.0” sleet. Crazy storm
Tbh I was surprised the sleet line blew past us all the way to Harrisburg PA given the arctic airmass we got. I figured the DMV would mix so I gave them 4-8” with 6-10 in the NW suburbs, which seems to have done okay. But I didn’t have southern PA going to sleet just a couple hours after we did!
