its funny how euro and gfs also show storms at 192-240 out....lose them for a few days and then bring them back. What causes this to always happen?

The GFS model resolution is 35km up to 192hrs. After 192hr the resolution doubles to 70km and the output is very unreliable, most of the data used at those time frames are climo driven.

Maybe, the further north and west you are the better in terms of temps but I wouldn't be surprised to see the NAM weaken on the next run or two and it really is the only model that gives much hope as it has the better dynamics. 

 

GFS hints at the possibility too though. We just need the nw side to be cranking a bit more. It might be too much to ask but we'll know in a couple days either way. 

 

12z gfs had a good swath of .5 precip over much of md and parts of nova. Rates are everything though. I'm just pointing out details.

Now that the models are converging on a solution/track ....what are thoughts on temps. When in doubt - look outside, right? Initially (based on models) people were forecasting 60 today in northern virginia, and low 50s tomorrow. It looks like most of us are still in the mid/upper 40s today ...so upper 50s/60 looks like it ain't happening. Thus, this air mass feels more stagnant than first forecasted and given the current track/solution ...snow Wed night is not out of the question for the DC area. I am still feeling a solid 1-2 inches DC area wide late Wed night.

Problem with that idea is that we're not in the airmass we'll be in for the storm.
