  1. Interesting update from BTV discussion:

    https://forecast.weather.gov/product.php?site=BTV&issuedby=BTV&product=AFD&format=CI&version=1&glossary=1

    .NEAR TERM /THROUGH SATURDAY/...
    As of 904 AM EST Friday...Interesting morning acrs our fa as
    widespread moderate to localized heavy snow continues acrs most
    of our cwa. Did get a report from NWS employee in Williston of
    some sleet mixing with the snow and sure enough radar shows 35
    to 40 dbz pocket in this area, not sure why as soundings are -8C
    or colder at all levels. Maybe combination of unsaturated DGZ
    and weak instability btwn 15kft and 20kft.
    
    Watching water vapor is pretty neat this morning, as mid lvl
    dry slot is quickly pushing into central/northern NY ahead of
    potent 5-7h short wave trof over the central Great Lakes. Within
    this dry slot KBUF sounding is indicating some steepening lapse
    rates within the 700 to 500mb layer, which is closely tied
    within the favorable snow growth region. So anticipating as
    better dynamics arrive btwn 15z-21z today, a period of moderate
    snowfall with embedded heavy snowfall still looks very
    reasonable from a SLK to BTV to MVL line. Snowfall rates of 1 to
    2 inches per hour with localized up to 3 inches is possible,
    given the convective potential per soundings. Just noted a cloud
    to ground lighting strike btwn Massena and Ottawa. Heaviest
    snowfall should arrive in the btwn area btwn 16z-18z, before
    shifting east. Expect very poor visibilities and hazardous
    driving conditions. The limiting factor to higher snowfall
    amounts wl be quick movement of system and moisture decreasing
    aft 21z. Did tweak snow ratios a bit this morning based on obs,
    which did make some minor adjustments to the snowfall. Still
    anticipating a widespread 6 to 12 inches. Snow ends by 00z this
    evening acrs most of the fa.

    Event totals: 0.6” Snow/0.43” L.E.

     

    Some models have been showing back side snow in our area from Winter Storm Nancy, but the signal wasn’t all that strong, so I hadn’t given it too much thought.  It definitely caught my attention this afternoon though.  There were a few flakes falling here and there in Burlington, but as I headed home westward into the mountains, the precipitation ramped up steadily.  Accumulations began to appear on the roads around Williston, and by the time I reached the Bolton area I encountered near whiteout conditions with snow-packed roads.  Here at the house, the intensity of the snow was enough that I had to put it down as “heavy snow”, since it was in excess of 1-2”/hr. while I was out making the 6:00 P.M. observations.

     

    I ran into this as well.  Very harrowing, near whiteout.  The lowest speed I saw was about 25.  I was in the Prius which has no fog lights so it was very difficult to see where the lanes were at times.  Lines of cars developed because the one in front couldn't see bumpkus.  I passed a few and regretted it each time.  The wind was not helping either.  

  4. I am amazed how every storm how people seem to forget that models tend to have have runs where they trend south about 3 days before storm, trend north about 2 days before, then South about 18 hours later with a last tick north.  It could all be in my head but it has seemed to happen every storm for a few years now.  With this trend north this morning, we should see a bump south again in the 0Z or 6Z runs overnight.

    Yea. I pick her up from my MILs every Tuesday night. Got off 84, came around the corner (dark, pouring rain) and thought I was dreaming when I saw something come across the road so I pumped the brakes and braced for impact. Luckily I was going about 30mph and probably hit it at 15mph maybe. Could have been worse.

    Eversource expects to have power restored to the remaining 400,000 customers who are in the dark from this tree fall no later than Monday.

     

    Glad both of you are okay.

    I hope those are the powerful LED lights that blind me from behind through the rearview mirror.  I like obnoxiously bright headlights.

    Hopefully you have an auto-dimming rear view mirror that, like mine, does not dim.  It makes things all the more fun when you have someone with their LED high-beams on behind you for ten miles.

    I've been a frequent visitor to the White Mountains since I first arrived as an undergrad at Plymouth State University in the autumn of 2001. I'm sure some folks in here have a better memory than mine, but I'm not sure I've ever witnessed the seasonal snowpack being wiped out in the month of February. There have been years where it took a long time to initially establish the seasonal snowpack...but usually once it's there, it stays through at least the end of March. Last year was perhaps the earliest melt-out I've seen, with the possible exception of 2016. 

    If you lose all of your natural snow next week, that will truly be noteworthy. I don't have official stats to back this up, but...that would be quite a significant deviation from the climatological norm in this area, if not close to unprecedented.

    Not February but the Grinch storm of 2007 wiped out my 23" pack in Bethlehem in a day. I think it was 12/23 give or take a day.

    This was issued by BTV at 5:15 this morning

    weatherstory.jpg?id=1645188739400

    Just made the drive up 89 to Burlington (BTV).  It was 41 as I left my house.  7 miles later I got on the highway in Sharon and it was 34 (where the 45 is shown).  20 miles up the highway it was 23 (where it shows the 52).  It was pretty much 52 the whole rest of the way, only took 10 or 15 minutes longer than usual.
