Odds favor 18z Gfs won't look like 12z. No consistency when it comes to snow "threats" all winter.

You never know how they are going to shake out, so you just roll the dice with guidance consensus.

Everything says a legit SSW event starting 3/11. Chilly end of March into April as a result is a good bet and just maybe an anomalous late season snow somewhere in the east.

All the ensembles are at .75"+. Forget the operationals, especially the Gfs.

I don't think the existence or non-existence of that storm in any way changes my need for counseling services.

That's why I always said you want to be in the bullseye area with the season's first synoptic event. Not necessarily "the" bullseye, but the bullseye stripe or area.

A lot of Nina conditions except for SSTA won't even allow it to be categorized as an official Niña oddly.

The refreshing thing is that next year won't look like that, but there's no support for it in the first place.

Today's updated March Cansips looking warm neutral to me. Here's a link to December. You can scroll forward from there. https://www.tropicaltidbits.com/analysis/models/?model=cansips&region=global&pkg=ssta_noice&runtime=2025030100&fh=9 On a different note, looks like a decent amount of blocking through the winter with cold along the northern tier into the MA fwiw.

I think this winter proved indisputably that using alphabet indexes exclusively for winter forecasting is far from a lock. To assume those indexes can be accurately forecasted in advance is equally as risky imho. Then throw in the nuances like variability during the winter and trends over the winter contrary to the anticipated final number (switching from + to - and vica versa) to name just a few, and it's accuracy is a cr@p shoot.

Your rolled forward didn't work this winter with the warmth and the PDO rose above -1 from -2, so it's not a guarantee, like everything else in weather prediction.

Almost there fwiw.

AI is south and not much. Looks more like a front. Completely lost the storm look. P.s. comes out early since yesterday's upgrade

It's 10:1 and temps are marginal,so it overdone even if it occurred as depicted. So it would still be a fail imby in all likelihood acting as the final dagger in the back of this winter by missing me to the north instead of south. Do I have the weenie mentality down or what? Lol

You mean spring?

That explains the jump in VA & WVA on the 24hr snowfall mean.

18z AI keeps it south.

And when you consider that all the ensemble 50% probabilities were as impressive as they were in addition to the means, it's an absolute head shaker, if not head against wall pounder!

That is correct. BWI had accumulating snows all 4 days.

Snow started at my house 2 miles north of BWI Friday night. It dropped a little over 2". That was the Arctic front. Snow stopped Saturday morning early, but then started back up late morning and lasted until late afternoon on Saturday. Saturday night featured a virga Blizzard. I dragged my wife and 2 kids out for a ride to "look for snow." We headed down Rt. 295 toward DC and finally had a few flurries not too far north of the DC line. I headed back home. When you get off of 295 by heading north toward Baltimore onto the Baltimore Beltway, you get a clear view of the Baltimore city skyline. The snow ceiling was incredibly low that night thanks to the Arctic air and you could see the snow above the city lit by the yellowish mercury vapor street lights. There were striations in the virga/ceiling. I'll never forget that view. When I got home and looked northward, I could still see the low ceiling gently dropping at that point. The snow started incredibly heavy and stayed that way all night dropping around a foot. I had 2 lightning strikes with the heavy snow that night. The NWS combined the 4 days (Fri-Mon) into 1 event and recorded 28.2" for the total, which would have been more had we not gotten heavy sleet late Sunday night into early Monday morning.

Heisey, I haven't looked at them, but the AI has ensembles. Lousy graphics, but this is the link to them fwiw. https://charts.ecmwf.int/?facets={"Product type"%3A["Experimental%3A AIFS"%2C"Experimental%3A AIFS Ensemble forecast"]%2C"Parameters"%3A[]%2C"Type"%3A[]%2C"Range"%3A[]}

Nope. 1 inch still a touch to my north. Plus it's 10:1, and temps suggest snow TV at best.

Heisey, et al., Pivotal has updated AI and now has snowfall. Here's the 6z run.
