Warning: I'll probably go for a bust even if models improve so may want to ignore my posts or put me on ignore

 

Naturally, I'll bust the other way, but, and I have to say it, the GFS members all showed distinct improvement over 6z.  I know, I know, too close to use them, but the fact that they all improved some has to say something.

 

What's going to be key for us (watchers) is do these improvements sustain themselves, do they continue.  Or are they a blip?

Snow hole on the GEFS too  :facepalm:

 

idk- I like the gefs all things considered. The area of heavier precip to the sw is what we have to count on. That's what I was alluding to in my earlier post about improvements @ 500. Just a couple slight improvements in amplification and the heavier area of waa gets here. Not saying I have confidence that it will but the 12z sure was a step in that direction.

I dont have the good maps...

 

But it holds serve on precip

 

>.10 for whole area..4 hour event

 

That's fine I guess. It's going to be a subtle one for sure. If the nam and gfs keep amping things a little this afternoon then it's looking like a whiff is off the table. Someone could squeeze 4" between the 2 events in less than 48 hours. That's pretty sweet imo.

true...1/8/11 wasnt awful...we only got 1/2", but I think northern burbs did better

 

jan 10 is definitely closer at 500.. don't recall specifics and wunderground radar isnt coming up but 2011 looked like a frontal passage almost

That's the one that came through in the early morning.  It was almost like a squall line of snow.  It was a Saturday morning.  A bunch of us were on here, watching on radar, traffic cams, etc.  It was fast, but cool.  It put down about 1.25 in Winchester.  Seems like I remember some areas up around Frederick getting close to 2, but I could be wrong on that one.

I'm leaning back towards widespread 2-3" with some areas approaching 4. The last 3 gfs runs are really encouraging @ 500 for getting the waa precip in here. There could be some bursts of heaver snow embedded (not bands). I have a hunch that 18z will hold serve or improve. It's going to be a quick hitter but every flake that falls will stick.

Either way, I think its the next 3 runs that will give us what we want to know.  By this time tomorrow we will have a pretty good idea.  I'm hopeful that the improving trend continues.

Yea, and considering the airmass, we only need .15 to get to 2" pretty much everywhere. I don't think .15 - .2 across most of the area is all that far fetched. And if I'm wrong...who cares?

Question for ya....With the way this WV image looks, we have a brutal dry air mass in place, which will prevent the storm but tapping additional moisture.  What could change to open up this source? Anything?  Just trying to get a little less weenie.  ^_^

 

Or is it mostly due to the flatness?
