 Don't look now, but the 0Z Doc may be setting up for a major SE winter storm at hour 162 in the southern plains. Let's see how this goes from here. 

 

Wow!!!!!!!!!!!!!!!!!!! Boom!!!!!!!!!!!!!!

 

Historic SE winter storm 1/31-2/1 on 0Z Doc!!!

Don't have any pay maps. What areas of the SE does it effect?

It must be said the Doc is the only model hanging back a closed low in Southern CA which then ejects later on to give the SE the potential snow. Ukie, GFS. GFS ENS, GGEM all have a progressive short wave that phases in with the northern branch 3-4 days earlier. Now this is the second run of the Euro which has done this slower thing, lending a bit more confidence, but we area loooong way from getting excited about this- I want to see at least several more runs that have this scenario at the very least.

Looking at the 0Z suites (haven't looked at ensembles yet) the 0Z Euro and 0Z NOGAPS both close off at the base of next week's trough around day 4-5 and GFS, CMC, and UKMET do not.  One could say it is the known bias of the Euro in holding back energy out west, but if I'm not mistaken, someone correct me if I'm wrong, but the Euro/NOGAPS were first to suggest the cutoff/ULL low with last weeks system, and the rest of the models started to pickup on it as we grew closer to the event.

Cheez,

 Thanks for bringing me back from this fantastic fantasy lol. Seriously, I agree as this would still be 6.5+ days out. Very low confidence this far away. Just shows the potential if everything were to happen to line up just right.

 

 By the way, it appears that there may be several inches of accumulating sleet within the southern edge of the accumulating winter precip. based on this wintry precip. being a little south of the 850 mb 0 C line for the bulk of the storm. Some of this appears to be over Tony's place. Hopefully, he is sleeping. I wouldn't want to get him overexcited as he wouldn't be able to sleep. Shhhh, please nobody tell him! Let him have a very nice surprise when he wakes up.

Interesting snippet from BMX this morning.....

 

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
412 AM CST FRI JAN 25 2013

.SYNOPSIS...
THE TYPICAL WINTER ROLLERCOASTER APPEARS LIKE IT WILL CONTINUE
INTO THE BEGINNING OF FEBRUARY. THIS PERIOD WILL BE CHARACTERIZED
BY LARGE TEMPERATURE GRADIENTS ON ANY PARTICULAR DAY...BRUSHES OF
WINTRY PRECIP THREATS...THUNDERSTORMS...AND BIG SWINGS IN THE HIGHS
AND LOWS. TIMING DETAILS WITH ANY OF THESE FEATURES CAN LEAD TO
LARGE DIFFERENCES IN THE DAY TO DAY FORECAST.

From the HPC this mornings extended forecast disco......

 

THE EUROPEAN GUIDANCE IS OFTEN
THE FIRST TO LATCH CORRECTLY ONTO A NEW TREND, SO GAVE IT HALF THE
WEIGHTING IN THE MANUAL BLEND. BALANCED THE REMAINDER OF THE BLEND
WITH THE MORE PHASED/PROGRESSIVE 12Z/24 GEFS MEAN. THE RESULT IS
THE AMORPHOUS BLEND OF TWO DISPARATE ENSEMBLE MEANS, WHICH RENDERS
DISCUSSION OF THE PARTICULARS OF ANY GIVEN SYNOPTIC SYSTEM MOOT
UNTIL THE BIG PICTURE BECOMES CLEARER.

There was 0 support on the 18z GFS individual ensemble members, and one supporting on the 0z. What a member it was too. Clocked a LOT on this board. I want to see more ind members on 6z so we can say we see a trend.

I agree, the euro is on it's own. Hard to trust it until we see additional model support.

If memory serves (and I'm on very little sleep), I think the Euro was initially the only model that caught onto the piece of last week's trough hanging back. Turned out to be correct obviously.

I think Robert back in November made a great point on how the euro seems to lead the way with big storms and smaller ones not so much. Example, the Christmas storm of 2010.

I was actually using the gfs members to show while 18z said impossible, 0z said the Euro was possible. I would always give more weight to the Euro, especially if its own ensembles generally support the op.

sorry, I mis read your post. Hopefully the gfs moves towards the euro and it has the correct solution

So we have a barrage of accum maps for a storm that was never going to be snow for most if not all (todays system) - yet we can't get an accum map of the fantasy snow from the epic storm on the euro.

 

wunderground picked a great day for its maps to screw up. I can't get any panels beyond day 5 or so.

He will likely post the accu-pro paid map later today...I don't want to look at it just yet! It is historic.
