SR Airglow Posted December 5, 2014 Share Posted December 5, 2014 GYX maps both look pretty solid to me really. Driving up to SR tomorrow morning leaving BOS at 6, skiing, and then going to my friends cabin in NH, hopefully it isn't too bad on the roads.

SR Airglow Posted December 5, 2014 Share Posted December 5, 2014 And the usual best advice? Don't drive like an azz in ice and snow. Absolutely. I'm not driving thankfully(I absolutely hate driving in wintry precip and try to avoid it as much as possible), but my friend is from NVT so he's got good experience in snow and he's got 4wd so we should be all set. 12z GFS seems almost identical to the 6z, perhaps a hair warmer. Seems like we've got a pretty good consensus on modeling really that basically verifies the GYX maps nicely. Link to comment Share on other sites More sharing options...

People feel like king kong with 4 wheel drive but icy roads don't give two ****z, You just end up further in the woods with 4 wheel drive because of the higher rates of speed that some seem to think they can acheive Link to comment Share on other sites More sharing options...

Driving up to SR tomorrow morning leaving BOS at 6, skiing, and then going to my friends cabin in NH, hopefully it isn't too bad on the roads. How is Maine usually with keeping stuff clean during an event? The plows go by frequently so snow buildup usually isn't an issue unless it's a mega-dump. On most primary roads they've switched from sand to liquid salt, very good for those driving after the storm is over because (unless it's really cold) it gets the frozen stuff off the pavement in short order. However, while the snow is falling, I find the roads more slimy/slippery than when sand is used. That said, in +SN everyone but the occasional true idiot slows considerably. It's often more dangerous in a lighter/smaller event because lots of people equate light snow with "okay to go". Link to comment Share on other sites More sharing options...

And that is when black ice becomes more problematic at the onset of the precip, Tomorrows system is a great candidate for it as we had lows in the single numbers overnight Link to comment Share on other sites More sharing options...
moneypitmike Posted December 5, 2014 Share Posted December 5, 2014 1040.7mb on my console. millibars sound more extreme. Got to 1044.2 earlier today Down to 1041.6 now with clouds increasing. 30.7/16 Link to comment Share on other sites More sharing options...
dendrite Posted December 5, 2014 Share Posted December 5, 2014 Got to 1044.2 earlier today Down to 1041.6 now with clouds increasing. 30.7/16 That sounds way too high. I think you need to calibrate your barometer. Link to comment Share on other sites More sharing options...
tamarack Posted December 5, 2014 Share Posted December 5, 2014 Dews remain in the single numbers thru central Maine, just like 3 days ago. GYX making us wait a bit for the afternoon update, also like last Tuesday - marginal conditions going into a possibly significant impact event must cause a bit of heartburn for forecasters. Edit: GYX snowfall map is the same one posted this morning. However, their 6-hr tracking tool now dumps 7" at Conway and 5"+ in the W.Maine foothills, a nice bump from earlier.

moneypitmike Posted December 5, 2014 Share Posted December 5, 2014 That sounds way too high. I think you need to calibrate your barometer. I think you're right. The highest I see from the nearest 5 airports (25-50 miles away) was 1039. They're now showing 1036 and I'm at 1040. Methinks the WWA for here is hardly necessary. 31.2/19 Link to comment Share on other sites More sharing options...
