RedSky Posted February 17 Share Posted February 17 Guidance has nailed the strong narrow frontogenic feature now stretching through PA north of Harrisburg, it's where it tracks from there. 1 Link to comment Share on other sites More sharing options...

MGorse Posted February 17 Share Posted February 17 2 minutes ago, Birds~69 said: This line around Pitt is cool, no idea what it means, if anything, That is a result of tightening 700 mb frontogentic forcing. This is sloped ascent and this narrow band is on the north side of the 700 mb frontogensis. That translates eastward, but let’s see if it remains so narrow like that. 5 Link to comment Share on other sites More sharing options...

LVblizzard Posted February 17 Share Posted February 17 The NAM pulled this same crap right before the last storm, cutting way back on totals right before the storm starts. Not sure I’m buying it, especially with the radar looking good. Link to comment Share on other sites More sharing options...

I guess we just cannot know yet where these precious bands are going to set up with 1-2" snowfall rates. I will check back at 2:30 am. Link to comment Share on other sites More sharing options...

I don’t think it is subsidence, but rather weaker lift outside of the strong lift that is producing the band. 3 Link to comment Share on other sites More sharing options...
