March 5-6 Storm Discussion

Robert just send up a status update on facebook...already noting the inaccuracy between the models and real-time data...

 

 

Take a close look at this picture. This is exactly what Wxsouth has been talking about for a couple of days ...it will be extremely critical on this developing upper low as to exactly where it begins to take on shape and when it starts to drop south.
Already the 18z Run of GFS is wrong. Looking back, the 12z was too. The inset image on the left showed that valid right now (10 PM) the model was predicting the circulation center to be just east of north-central Montana. The water vapor loop clearly shows it is 125 miles west of where the Model predicted it to be just 6 hours ago. Overall in the big Global Scale picture, not a huge error. But as far as forecasting for the folks downstream in the Eastern US, this will have a big impact. That's why WxSouth has been stating the importance of exactly where the ULL will begin to drop further south and just how far east it gets before the southeastward dive.

Nice to see the NAM trend south, but for those of us south of I-40, it kind of feels like hitting a few three-pointers to cut the lead to 20 with under 2 minutes left. Still not going to change the final outcome. Too bad that southeast jog that happens near the end of the run couldn't come sooner.

Hope it keeps trending, though, so at least some folks on this board (HKYWX, et al) can get in on the action.

If we can't all cash in, here's hoping at least some of the long-suffering get to leave the table with a little folding money when the river card turns.

Can I ask an honest question, do y'all really expect a huge shift south? I'm really being serious. DT call for that much snow in the triad is laughable at best.

Nah. I never believe DT. It could make a shorter drive into VA for me on Tues.

The Euro has had several runs in a row showing accumulating snow in INT and GSO, I am sure DT is hugging the Euro. You not buying it.

I don't. The only thing I will say is that DT really puts much, much, much more time into the Virginia and points north parts of his map than NC. Not an excuse, just an explanation.

I don't but its really hard to ignore the 150-200 mile shift south in the southern part of the accumulations from the 18z NAM to the 00z Nam.  One more shift like that and I-40 and North in NC is in the game.

I don't think anyone expects a huge shift south, but forecasting can be humbling...I mean, who thought the SC upstate and Charlotte area would experience widespread thundersnow with accumulations in the 2 to 5 inch range on Feb 16th?

The nam has been terrible lately. See that's my problem with DT, ya I said it. I live in GA but I put time and energy into making a forecast for everyone. Not just my backyard and up north where there is more people for website views. Ok rant over. Lol

He certainly is going out on a limb with this one. Who knows if it will happen...... I believe we all agree that if we don't see something encouraging by tomorrow morning, then this will not be our storm. Models are fairly accurate within 48 hours when there is good agreement.

I agree with that. My rant/post was geared more to the people that talk/hang onto laughable models just because it shows the solution they want. MOST people on here don't do that though.

Disc and I are the northern most southeastern posters so I'm not expecting a gigantic shift either but I only need a slight one to get plastered aka Euro which had 1.75 and now nam I believe had 1.25-1.50 so if Gfs comes in I may get excited. Really wish this storm system could have been a little more south for everyone.

Be careful. It's the NAM

I certainly don't believe his first guess map will come close to verifying in NC, I was just passing along the map for people to see...  or make fun of, whichever it's all good!!! lol

 

Good to hear. Because after his 1/17 call of a foot in Mount Airy on the day of the storm...he is not on a limb. NC is not his forecast zone to worry about.
