  1. Light snow and blowing snow  -14.6F

    I'm surprised it clouded up and light snow for the past 30 minutes.  Vis less than 2 miles

    I am now approaching the 2016 temperature record for me.  Perhaps later this evening I will take some boiling water out and see if I can make some snow.  I will record it on the phone.  Just got to get it a bit colder

    Having lived in New England most all my life...we do get these extreme cold spells we are having here now..Yes it is cold…brrrr.. but it's not like it is some novel event never experienced here before. Yet that is what the media act like.

    In the 32 years of living up here in Central NH it has never been -12F at 4:30pm.  So for this point of the day it is an extreme event.

  3. It's finally cooling off nicely up here.  From the late morning till early afternoon I hung around 0F.  Over the past hour temperatures have been falling.   Down to -6F with the aid of a lot of Cu/virga so we are not in full sun as earlier.  Winds are roaring through the trees.

    Pack is a solid 11".  Glaciated  with that sleet we had in the last storm.  The snow slides off our metal roof but I have been doing some roof raking in the flatter areas just to keep the extra weight off  in the event of future big storms that I really don't see right now.   Looking forward to later this evening.  Models show me bottoming at -22F but I doubt that will happen.  Years ago I had a -19F and I think in 2016 about a -14F.

    entered the negatives at the cabin -0.1F, 14.4F in Lowell

    We are just behind you,  +.9F and going down.  We got a 1/4" squall around 2am.  Peak wind was 26mph.  Although trees and the hill block me from the NW there is still very little wind.  Mostly 2-12mph on the Davis at 10 meters above ground.

  5. Although we don't have kids I decided to call our school district superintendent's office to suggest cancelling school.  Up here 125 miles north of Boston the cold is going to be well established by school time.  Anyhow I got the superintendent's secretary.  She thanked me for my concern but the tone in her voice was like, this guy is a nut!  I don't think school systems have any guidance in place for cancelling schools except for snow type events.

    Two invasive insect species of concern in NE could have significant mortality of this year's population, if we can get cold enough.  Both the Emarald Ash Borer (EAB) and Hemlock Woolly Adelgid (HWA) populations are susceptible to anomalous cold events, especially as temps approach -20F.
    "...researchers from the U. S. Forest Service and Minnesota Department of Agriculture found that the supercooling temperature for the Minnesota EAB population was about -13°F. Based on these results, a model was created that predicts that about five percent of EAB larvae should die when temperatures reach 0°F, 34 percent at -10°F, 79 percent at -20°F, and an impressive 98 percent should die at -30°F. (Venette, R.C. & Abrahamson, M. (2010) Cold hardiness of emerald ash borer  PDF , Agrilus planipennis: a new perspective.) 

    Studies on the HWA show similar results.  Also their mortality is higher when the cold occurs after a period of relatively milder conditions, as the insects gradually adapt their supercooling ability in sustained cold periods, so this event holds promise for a (temporary) setback for these insects in 2023 in NE.  I'm cheering for -20F here overnight Friday for that reason alone.  Seems like an ideal setup to hamper those invasives for a season anyway, while not prolonging the severe conditions for people and wildlife.  Bring it!

     

    In addition perhaps the Moose ticks will be killed.  Winters have been so mild.  A quick freeze job for them too!

  7. Friday afternoon should be the coldest I can remember up here.  These are crazy low temperatures when people are out and about.  The cold front is through here by early morning with potential snow squalls with temps near 0F and just drops all day from there.

    We have a deep snow cover and that will help keep it cold.  If we are going to get cold we might as well go big.  It is in and out.  I can take that.  It is the endless cold that I hate.  This is at 5pm

  8. Snowmobilers are everywhere today.  Conditions are good but they need one more storm to make conditions great.  Don't see anything of significance this week more than some fast flow moisture starved systems.

    That signal for real cold remains for next weekend.  Euro has even got a bit colder with the 12Z runs.  For most of us it has a -25 to -30F morning next Saturday rising to a high of -15F during the day.  In the longer range things seem amplified but even if you took  ten degrees off to account for that it still would be crazy cold.

    EDIT:  I posted this before I even read the forums.  I now see it discussed in detail in the Feb thread.

    Snowpack is down to about 3" in Lowell. About 1/2" of frozen, followed by about 1.5" of rain. Currently sitting at 36.1F.

    I'm guessing we got around 4" of snow last night up at the cabin, followed by an hour or so of sleet, then about 1/4" of rain. I'm guessing a little compaction, but the rain that fell probably got absorbed by the recent snow. Temps rose to 33 by this morning and holding steady at 32.

    Yeah compacted to 4" here.  Trees are glazed but snow is deep.  We had a nice layer of sleet so it is powder underneath

    The CAD from Gene to Jeff, and to some extent to Brian is remarkable.  We are 30/28 here.  I CAD pretty well, as this whole area does, but Brian and Gene are at another level.

    Finally at 8:15am I have hit 32   Snow to sleet to end as freezing rain here.  I didn't not measure during the storm but now it is an ice crusted 4"

    It means something. We have a bit of a barrier jet going and we’re advecting some of that low level cold in Maine our way. I’m at my low for the day now…25.9° and a steady drop. So we’ll torch aloft over the next few hours, but we’ll hold sleet and eventually ZR for awhile.

    I’m waiting to clear the mess. I’m hoping we just crust the surface and hold the snow consistency at the bottom through the duration. 

    I am waiting till AM too. Interestingly the strong wind has stopped. No more roar in the trees. Temp and dew still at their lows
