Ginx snewx Posted December 21, 2010 Share Posted December 21, 2010 Yeah I've never seen it to that extreme though something is weird. On BR3 the leading edge would be here about now, but all I've got is some big flake light snow. I've never seen an instance where the radar is off that badly, what causes it again? I have been toggling GYX and Box on reflectivity GYX has the band rotated 30 degrees SE,, edge of radar stuff. Link to comment Share on other sites More sharing options...

CoastalWx Posted December 21, 2010 Share Posted December 21, 2010 It was easily down to 1/4 that report is la garbage My friend in Eastie said it got borderline mdt. That band could have weakened a little..I dunno. Link to comment Share on other sites More sharing options...

Clinch Leatherwood Posted December 21, 2010 Share Posted December 21, 2010 I have been toggling GYX and Box on reflectivity GYX has the band rotated 30 degrees SE,, edge of radar stuff. Yeah I think that's it. For Box it's as Scott said if I understand correctly - the snow is probably at an angle in the atmosphere. So it may appear that it's near me but it's actually the band to the south. I think that's mostly it for several hours. Still cannot believe school isn't called off.

Clinch Leatherwood Posted December 21, 2010 Share Posted December 21, 2010 One thing I'm sure of, the RGEM was about as bad as the UKMET and NOGAPS. 3 useless models on this storm. Link to comment Share on other sites More sharing options...
dendrite Posted December 21, 2010 Share Posted December 21, 2010 The rapid refresh (HRRR) is showing a punch of dry air at H85 moving in from the NE that is cutting off the precip on the back side of that band. That's why the composite and base radars are off so much and we're getting some 30dbZ vriga. It's probably helping to explain some of the forcing too.

HoarfrostHubb Posted December 21, 2010 Share Posted December 21, 2010 We got a dusting of really swirly pixie dust. Looks good in the floodlight The wind is nicely whipping. Enjoy it folks! I'm very happy for the folks who got nailed Link to comment Share on other sites More sharing options...

Clinch Leatherwood Posted December 21, 2010 Share Posted December 21, 2010 Ok so are we saying if I were to get in a hot air baloon and go straight up into those echoes it's snowing aloft or it's a radar distortion? I'm confused Link to comment Share on other sites More sharing options...

Clinch Leatherwood Posted December 21, 2010 Share Posted December 21, 2010 I normally use base, for some reason I was on composite tonight. USUALLY the differences are minor, how is the composite showing a band of heavy precip where there is none? I've seen it off by a few miles before, but that's nuts? Some of the BR tilts show the same thing....is it literally that it's virga, or that it's phantom echoes I'm between 10 and 11, that's all I'm comfortable saying as I don't play it by the book in terms of I cleared once all day. If someone nearby reported 9 wonderful I'm not going to argue. Link to comment Share on other sites More sharing options...

If someone nearby reported 9 wonderful I'm not going to argue. It could be echoes aloft too. If you notice GYX sounding, it's saturated above 700mb with a big warm spike. Snow could be generated at that level, but the drier air underneath is gobbling up the echoes. Link to comment Share on other sites More sharing options...
