Marion_NC_WX Posted February 21, 2013 Share Posted February 21, 2013 I think a lot of this is going to be about timing and how much Radiative cooling can take place before the clouds roll in Thursday night-Friday morning. Really for North Carolina its all about dewpoints and wetbulb temps as we go into tomorrow night. There is no tap to a cold air source. What we need to watch tomorrow are the dewpoints and wetbulb temps and see how they are compared to model projections. Link to comment Share on other sites More sharing options...

NCsandhills Posted February 21, 2013 Share Posted February 21, 2013 GFS has been trending pretty cold as well as the Euro for the first week of March. My biggest interest is in the March 1-March 7 area...seems like several favorable situations present themselves each run. Link to comment Share on other sites More sharing options...

superjames1992 Posted February 21, 2013 Share Posted February 21, 2013 The GGEM looked pretty cold and suppressed. At the end of the run, it gave Texas a good snow and then sent the SLP to Cuba at hr 240. Oh, yes, that is a 1052 mb HP up in Nunavut. Link to comment Share on other sites More sharing options...
Chattownsnow Posted February 21, 2013 Share Posted February 21, 2013 you mean the models lost the storm!?!?! i'm shocked. it amazes me to see these storms show up and disappear for the southeast but if one is headed for the plains or great lakes it's like it is locked in on day 6 lol. eh, maybe its because I'm really not paying as much attention to those storms and have a biased eye toward our sad little winter corner, but it sure seems that way lol.

dsaur Posted February 21, 2013 Share Posted February 21, 2013 Monday interests me. We'll see just how fast the atmosphere is changing, as close as that is on the Gfs. If all this change is for real, we'll start having possible after possible in the short range pretty soon. It'll be fun...get the juices going T Link to comment Share on other sites More sharing options...

Thickness is not even close on the Euro. A 1024 high moves from off the PA shore and turns into a 1028 high that stays in Maine for one frame while the bulk of the moisture moves in. I would take that with a grain of salt. Link to comment Share on other sites More sharing options...

I think all of really appreciate your posts and all of the work you have done on your website. I do sometimes have a hard time understanding all of the technical details and I don't know what I'm looking for and whether to celebrate or be bummed. If you could provide a brief word of explanation I think we could all learn something. Thanks! Link to comment Share on other sites More sharing options...

No seriously I don't understand what it has to do with it. I understand if you're talking about how the storm could affect the midwest I just have no clue what it has to do with the SE and pattern/future storm discussion.

Steve, Feel free to post it here if it's relevant to the discussion, which I'm assuming it is, or you probably would not have posted it. Add me to the list that doesn't understand what it means or rather how it affects things. Can you help us out? That's all we're asking. Link to comment Share on other sites More sharing options...
rduwx Posted February 21, 2013 Share Posted February 21, 2013 I, like others, have seen the potential in the upcoming pattern the LR models have been showing and can see reason for the excitement. My problem is we need to start seeing a storm on the models. If not all we have is a bunch of potential. I haven't seen a storm the last few runs of the gfs or euro and I'm affraid we might end up w/ cold and dry. Call me crazy or call it modelogy but I like to see the models showing something and get an uneasy feeling when they're not. Hopefully the 12z runs will start to show something!

A +pna is usually a dry pattern. And without a true southern stream we are left with relying on the northern branch to drop some energy out of Alaska. This is why a negative pna with a strong block can deliver. I would still keep my eye on that energy trying to come across late next week. Link to comment Share on other sites More sharing options...

Cold Rain Posted February 21, 2013 Share Posted February 21, 2013 I, like others, have seen the potential in the upcoming pattern the LR models have been showing and can see reason for excitement as we head into March. My problem is we need to start seeing a storm on the models. If not all we have is a bunch of potential. I haven't seen a storm the last few runs of the gfs or euro and I'm affraid we might end up w/ cold and dry. Call me crazy or call it modelogy but I like to see the models showing something and get an uneasy feeling when they're not. Hopefully the 12z runs will start to show something! I agree with you to an extent. In my mind, it's just a question of when [do we start seeing a storm]? For 7+ days out, I'm fine with seeing the players on the field. The trend for a strong west-based -NAO and a spike in the PNA continues. The energetic flow continues. So the pieces are there. To avoid the word verbatim, a perfect prog looks more cold and dry instead of snowstormish. But, come verification, things will likely line up differently. It would be nice to see a storm show up five days out and remain all the way in. But that's rarely how it works down here. But I'm with you....I want to see something legit start showing up soon that we can track. Link to comment Share on other sites More sharing options...
