The euro could care less if it nails something 7 days out. DT being so definitive on a snow event for the worst snow place on the planet 7 days out is mind boggling

Models dont CARE about or KNOW anything. They are number crunching mathematical equations. It still takes skill to look at patterns and analogs in addition to model guidance and make a good forecast. Any flaws in the models are a function of flaws in the algorithms that model the atmosphere. Its always human error..logic machines don't make mistakes.

I think things are finally clear enough to give a definitive call that we are dealing with a miller b with little snow potential for DC.

 

Reasons:

 

1) The ridge off the west coast is farther west than you'd like to keep the vort/trough digging enough to go south of us.

2)  The lack of any real blocking in the atlantic far enough south to force the vort/trough south of us.

3) more importantly,  the models are pretty consistent now in taking a low into the OH valley and then forming the low a little too far north for us to get anything of note except maybe a few flurried well after the low is past us if the down sloping will allow the vort provide any lifting. 

 

I'll be writing something tomorrow about jan 7-14.

after looking at the latest data, i dont see a winter storm threat for us on the horizon through 240 and beyond

i think these past 2 days have been an all time worse for me personally and this board.

In general life or in terms of how the weather/patterns are shaping up?  The Ravens' loss rubbed salt on the wound for me (especially when they would have gotten into the playoffs if they had won).  I guess I can rest easy knowing that they wouldn't have gotten far, though.

Great find Ji. Here's a preview of Wes's thoughts for that one as well:

"1) The ridge off the west coast is farther west than you'd like to keep the vort/trough digging enough to go south of us.

2)  The lack of any real blocking in the atlantic far enough south to force the vort/trough south of us.
