real Posted December 14, 2020 Share Posted December 14, 2020 The gradient even within the inner and outer (if-they-formally existed) Beltways could also be interesting. But frankly, in all my years of living in Washington, there have not been a lot of times where I lived downtown and was super jealous because someone in middle or lower Montgomery County or Fairfax County got a lot more snow than I did. There was a big storm around 2004 where DC got like 4 inches of snow and Columbia in Howard County got like 24 inches. There was also that March bust storm a few years ago where DC got almost nothing while parts of Fairfax may have gotten 6 inches. But those seem rather rare, lately, in part because may the suburbs are becoming denser and warmer too. DC versus upper Montgomery/Frederick/Carroll/Loudoun/Northern Baltimore County is a different situation. Link to comment Share on other sites More sharing options...

I don’t buy that at all. Let’s wait for the gfs ICON maps on TT do not show mix. So when it shows rain over your house with temps in the upper 20s, that's either sleet or ZR. I assume that is what its causing the confusion. Link to comment Share on other sites More sharing options...

Meaningfully less snow inside the beltway for sure but temps are still pretty cold, so a decent amount of mix and not a complete washout. Link to comment Share on other sites More sharing options...

Kleimax Posted December 14, 2020 Share Posted December 14, 2020 NAM/ RGEM / ICON show the low heading due north from coastal NC straight up into the Delmarva. Not what we want to see. Need that thing to slide off the coast east of OC. 1 Link to comment Share on other sites More sharing options...

I was thinking Winchester, VA but not sure if that will even be too close to the mix right now. I don't want to have to go all the way to Harrsburg, PA. Go NW of Winchester. Maybe Berkeley Springs? Or if you want to stay in the 81 Corridor I think Hagerstown is a good spot. Link to comment Share on other sites More sharing options...

I’ve seen a number of modeled storms over the years where my old home just north of the Balt beltway would get 8”+ while Wes got next to nothing. In reality it almost never happens. Yes. Either DC gets in on some action, or the storm somewhat disappoints out here too (March 2013 a good example). Hopefully, Wednesday is the former, and not the latter.

We didn't even MIX for most of the day while Cantore broadcast from the Mall. Meanwhile I had co-workers out in the boonies snowed in for days...

I ended up getting 9" that night from the WAA, which did perform here, but nothing else once the coastal failed. I put that storm solidly in the disappoint category. Not a major snow storm out here.

That's just living in the area for 25 years and knowing how these tend to go especially this early in the season. you guys are not looking at the overall pattern.. which favors lower temp profiles.. March 2013 was a completely different set up. At 12Z Wednesday temps are in the low 20s throughout central PA and the core of the cold air mass is the coldest temps Eastern North America has seen so far this winter. We have a ~1040 HP system forcing that cold air mass in to our area.. I keep saying this.. but I really think we over-perform with temps! Link to comment Share on other sites More sharing options...
