MN Transplant Posted January 21, 2016 Share Posted January 21, 2016 Does this imply lots of Thundersnow? It could imply thundersnow. Soundings would be a better tell. Wes is good at looking for the important details there. Link to comment Share on other sites More sharing options...

BTRWx Posted January 21, 2016 Share Posted January 21, 2016 I want people to see this to show you how crazy the NAM model can be. Look at the moisture differences over Arkansas. The first map is the 18z NAM @ 30 hours, 2nd is the 00z NAM @ 24 hours...just unbelievable differences for this short a time span on a model. 30nam.gif 24nam.gif Looks pretty darn good to me as far as consistency eta: overall. Arkansas is one of only few anomalies on the map to my eyes. I didn't even notice that fine line difference. Link to comment Share on other sites More sharing options...

clskinsfan Posted January 21, 2016 Share Posted January 21, 2016 Frederick Co/Winchester special. Looks like a more traditional snow map for this area.

NinjaWarrior2 Posted January 21, 2016 Share Posted January 21, 2016 LOL New York City gets 2' this run , another long duration storm on the NAM, but since NAM might be too AMPED... I really like our chances. Link to comment Share on other sites More sharing options...

PhineasC Posted January 21, 2016 Share Posted January 21, 2016 NAM wants to put some of us at 66hrs in the dry slot http://mag.ncep.noaa.gov/Image.php?fhr=066ℑ=data%2Fnam%2F00%2Fnam_namer_066_700_rh_ht.gif&model=nam&area=namer¶m=700_rh_ht&group=Model+Guidance&preselected_formatted_cycle_date=20160121+00+UTC&imageSize=M&ps=model The danger of relying on deform band snows. NAM puts us under hours of light snow while PA and western MD are clobbered. Good thing it had healthy front-end snows to help make up the difference. Glad it's just the NAM.
