CoastalWx Posted November 23, 2011 Share Posted November 23, 2011 GFS is a smidge colder this run. All snow here through 12z with about 1.00" QPF. I think I end up with about 0.50"-0.75" as snow and then a good 0.25" as sleet. 9:1 ratios for the snow give me 4-6" and then an additional 3:1 of sleet for another 1" is a total of 5-7". Time for sleep...I'll be up early. Good luck man. Enjoy. Hopefully that IP line doesn't race in too quick. Link to comment Share on other sites More sharing options...
Organizing Low Posted November 23, 2011 Share Posted November 23, 2011 looking at latest guidance and radar and obs, i'm thinking local accums to 3-6 in the city proper, with higher amounts 4-8 inches S of the city towards and along the VT border. as is usually the case in MTL, 1st snow + rush hour = disaster in AM Link to comment Share on other sites More sharing options...

OKpowdah Posted November 23, 2011 Share Posted November 23, 2011 Snowing at a good clip, though poor crystals. Maybe a half inch by now. This will be fun for someone: Link to comment Share on other sites More sharing options...
dendrite Posted November 23, 2011 Share Posted November 23, 2011 Latest HRRR is quite a bit cooler at 850mb at 12z. Hopefully those UVVs help the marginal layer and keep the sleet at bay for a little longer. Link to comment Share on other sites More sharing options...
mahk_webstah Posted November 23, 2011 Share Posted November 23, 2011 eyeballing it looks like at least 4 inches, but the snow growth is not impressive and boy is it wet snow. heavy echoes to the south moving north so we shall see. Precip doesn't seem very heavy so I'm sort of surprised it hasn't changed over yet. Link to comment Share on other sites More sharing options...
