Tail of two states. Definitely no winter here yet. Nice and mild for now. 

Driving between ORH and Natick the snow dropped off very rapidly between about Shrewsbury on 290 (which has some elevation there...maybe 700+ feet) and Marlborough before hitting 495. 

December was pretty solid in the stats for ORH. 17.5" of snow and about normal temps. Good start to winter. Not perfect but can't complain at all about it.

~13 .5 " here with normal temps.

Not great but snowy enough to wet the weenie.

What was missing was pack. 4 days now is the most for month. I'm sure the Rainer washes it away Tuesday

Yeah not surprising. Could have used a bit more, but no complaints compared to last year.  Just hoping later this week works out. It's at least nice to have a running start to the season for a lot of the area.

Happy New Year Northern New Englanders...

 

27.5"  snow for December.  Not bad at all even considering only 7.5" from the big storm that just grazed us.  

Amazing that 50 miles to my south there is bare ground showing.  Solid snow cover all month.  Tuesday looks like its just going to glaciate the pack even more.  Snowmobilers are finally getting some use out of their sleds after last winters disaster. 

Newfound Lake is 3/4 open.  The southern bay is frozen and bobhouses going out and snowmobilers are out on the ice today.  I can't see that the ice is very thick.  We had the one cold blast but not a lot of the cold.  The ice was thin and now is covered with that 7" of snow.  So there is no way to tell what is just skim ice.  Accidents waiting to happen on NH big lakes right now....  Probably late week cold snap will help thicken and expand ice cover.

I read a report of 7" of ice south of Mayhew Island. I'm sure it takes alot to freeze the main lake between the depth and the wind. I've been out in the spring with a NW wind and that lake is brutal in the wind. 

You are right about gradient. It's the near the MA/NH line along the 93 corridor (I know the highway can be a bad approx cause it's so exposed) but it rapidly drops off south of Salem to patchy coverage.

I am writing an article on heat waves and doing some searching so I can perhaps find what the thresholds are for each region...not having much luck on links :/

but I did come across something for the Northeast that said 3-consecutive 90+ days does not always mean a heat wave as it also depends on degree of humidity... Is this true? I always thought it was the temp which defined heat wave...didn't know it also depends on humidity

Kevin can provide the thresholds in units of toilet paper needed.

idk if there's really any official definition out there. Everyone just uses 3 consecutive 90+ days in the northern states.

Yeah I only seem to find something for the northeast but can't find anything for like the southeast, southwest, northern Plains, etc.  

i don't think that's a huge deal.  What I'm going to focus on more is the atmospheric patterns which are favorable to producing prolonged periods of "excessive heat".  What I may do is use the summer of 1995 as an example...that's the last extreme major heat wave I can think of which affected such an extensive area

A tenth under 40" here, 2nd snowiest DEC (behind the 46.2" of 2007) and 4th snowiest of any month.  When I fill in the temps for the days we were in NJ, the month should come in about 5F BN, 2nd or 3rd coldest of 19 Decembers here.  Given that, plus 2 mornings -20 or below and the rare 20"+ event, Dec 2016 rates an "A" on my totally subjective grade scale.

Question for the weather station gurus out there. I have a 10+ year old Vantage Pro 2. The anemometer has stopped transmitting data, the rain gauge has also stopped recently and I have not upgraded the temperature sensor yet. At this point, it is worth looking into getting a new unit? Not sure the wife would be happy with my spending $500+ on a new one. Thoughts on the Ambient Weather WS-1200-IP or the Davis 6250 Vantage Vue? Thanks!

Contact Davis about their refurb repairs. You send the whole station out to them and they fix whatever issues you have. Last I knew it was a little over $100 not including shipping.

this is kinda interesting...

AMS' recent report on the state of the climate ...

" A massive cold wave struck the entire eastern seaboard in February 2015, from Maine to Florida. The month ranked as one of the coldest and snowiest February on record for the region. Climate change, which has actually reduced the likelihood of such extreme cold waves in the North Atlantic due to rising temperatures, was not deemed responsible. Per the report, this was “a one-in-15-year event in terms of intensity and a one-in-64-year event in terms of duration.”

For New England itself it was definitely rarer on the return scale. It was a bit less intense further south.

Couple things on that ...

One, a particularly astounding experience for me was the repeating snows storms with unusually cold temperatures. I believe there were two nearly back to back where temperatures along Rt 2 up here in northern Massachusetts hovered < 10 F during the duration of the snow event, and one of those we were still in the midst of 1/2 mi visibility with occasional reductions to mere feet in blowing snow, while the temperature was -1 F. That was the coldest combination of > than non-advisory level snow fall with temperature I had ever experienced; the nearest one was a +3 F with moderate crystals like fog mixed with blowing snow in western Michigan dating back to 1981 (under certain conditions, it can get so cold in a LE scenario that the 'streets' and convective nodules smear into a low dbz haze).

Second, there are layers of misconception among the lay-stay of society's population. Those with any care to venture an understanding that I have encountered actually intimated they believed that global warming (ironically) contributed to the pattern that caused that excessive winter expression.  I find that 'refreshing' that there are people out there that think at a deeper dimension than the ad nauseam "hot day ... must Global Warming" (unga-bunga); even though according to AMS, the scientific research doesn't support the idea that the cold month was in fact GW related.  interesting...

Yeah. Attribution studies are generally pretty ambiguous on that type of stuff. Obviously the media headlines often exaggerate or flat out get the story wrong on that. 

At any rate, it's probably just a great example of the natural variability of our climate being orders of magnitude greater than the underlying warming trend on that type of time scale and geographic area. Like, we probably can't get our coldest year or coldest decade on record these days but we can still get our coldest month on record regionally or locally. 

What was so impressive about late January and February 2015 aside from the obvious cold and snow records, was the pattern itself that produced it. We almost had this perpetual lay stationary PNA ridge in the perfect spot for eastern New England. It would reload in the same spot multiple times before finally waning. The one time it didn't reload immediately and the rest of the CONUS torched, we got lucky on a little local cold nose of high pressure from Quebec and had a 60 hour overrunning snowstorm at 15-20F...while it was 60 in Chicago and near 70F in DC. I suppose in order to get 100" of snow in 3 weeks you need to catch a "break" like that...somehow Logan airport pulls off 24" of snow while the rest of the country bathes in a February spring for a couple days.

not sure if anything from 2/2015 can match the January 2-3rd 2014 snow event in terms of cold / wind combo 

https://www.wunderground.com/history/airport/KORH/2014/1/3/DailyHistory.html

Doubt I'll ever see a legit warning criteria snowstorm with temps hovering either side of 0 like that again in these parts. Those Obs from ORH are ridiculous .. multiple hours of temps below zero, wind chills below -20 and 1/2 - 3/4 mi visibility obs.

Just drove down to Boston from Central NH. Deep snowcover north of Concord NH.  Solid snowcover down to about Manchester/Nashua.  Snowcover diminishes to about a light coating in the Burlington/Woburn area.  South of Rt 128 there is nothing.  Nice to see some bare ground.  It's been since Novemeber for me....
