CoastalWx Posted January 21, 2013 Share Posted January 21, 2013 Someone care to educate me on how to interpret that? Those lines running across the image was the dendritic growth zone. In between those lines is the zone from -10C to -20C. Now see those red lines? That is lift. So a you can see we have a bullseye of lift smack in the middle of the dendritic growth zone. That means sick snow growth potentially. Link to comment Share on other sites More sharing options...
mattb65 Posted January 21, 2013 Share Posted January 21, 2013 Jerry can u link an image of btv wrf total precip or a recap of qpf totals/max areas. Or anyone 4km BTV WRF has around 0.5" for most of the cape, gradient from 0.25 to 0.5 west to east across boston metro increasing towards the northeast with a qpf max offshore of 2.75" east of the MA/NH border with weenie 1.25"+ for areas northeast of BVY up to around portsmouth. 12km WRF has boston in a screw zone with just around 0.1" but 0.5" for the cape and a good 0.75" focused further NE toward portsmouth. http://www.erh.noaa.gov/btv/html/4kmwrf/ Link to comment Share on other sites More sharing options...

Ryan Posted January 21, 2013 Share Posted January 21, 2013 Can you tell us about the 4km? 4-6" from Kennebunk ME to Plymouth MA, west to 495, north to CON. Spotty 6-8" areas in between... heaviest axis 6-8"+ from right along the NH seacoast thru coastal Essex county... jackpot 8-12"+ near Beverly.

Very nice SREF signal for DGZ in excess of 100 mb too. If you loop it, you can see it really hang back across SE NH in the inverted trough.

mattb65 Posted January 21, 2013 Share Posted January 21, 2013 Boston screw zone..shocking. From what I'm reading, 4km might have a better handle on things given how mesoscale these little norlun animals are. We'll see how things go, hopefully we get a nice 2-4" and if we bust higher that'll just be a bonus. Link to comment Share on other sites More sharing options...

Ryan Posted January 21, 2013 Share Posted January 21, 2013 Thank you. Nice! I hope it all works out not for the reason that I love snow (I'm at school so I'm missing out anyway)... but to show that the higher resolution models can be more useful in situations like this.
