Sunday, December 27

Messy Mix Monday

Written by: Stacey Pensgen

Classic setup Monday for at least a little ice. Canadian High funneling in cold, Northeasterly wind locks sub-freezing temps at the surface. Meanwhile, the deep south system opens up and moves northward, spreading moisture and warm air over. The question is - how much snow? How much sleet? How much freezing rain? Freezing rain amounts don't look overly impressive, but we all know any little bit of ice can be treacherous on roads and sidewalks. Doesn't appear to be enough to cause any major power outages.

Now, could the snow be enough to knock us out of the "least snow in December" running? Possibly. It would take 2.6" to do that. If we do NOT get that in this system, the least snow in December record may stand. Yes, it looks like some snow in the form of lake effect late week, but could end up being another 'east of the lakes' event, leaving the ROC snow-free. But this is lake effect, and trying to forecast where and how much 5 days in advance is just moronic :)

  5. Finally it feels like late December outside, cold with snow showers fling. I love it. Winter is getting ready to return, with multiple troughs and possibly a potent clipper at weeks end, I suspect the ground will be white come this weekend.

  7. The WWA text says this about ice accretion:

    "ICE ACCUMULATING UP TO ONE THIRD OF AN INCH TONIGHT AND A FEW HUNDREDTHS OF AN INCH TUESDAY...LEADING TO STORM TOTALS OF UP TO ONE THIRD OF AN INCH."

    That's enough ice for scattered power outages, especially when it's coupled with the stiff breeze we're going to get. Hopefully that's overdone and most of it ends up being snow/sleet instead, or even just liquid rain for that matter.

  8. So this pattern change that is coming, are we talking about a change to more seasonable temps with snow chances or will it be like last year with shots of polar air? Honestly not looking forward to what we had last Feb but some typical winter weather is fine by me.

    1. Seasonably cold with lake effect (mainly in the snowbelts but some may cross the ROC metro, too early to call) and a possible clipper.

      Delete
  9. I'm looking through KROC's 3 day history as I observe some unexpected very light patches of snow outside. Light snow and 25 degrees at 9:54 AM with 0.01" of liquid equivalent measured. It's possible that the December snow shutout will have been broken before the main system even gets here, albeit by the bare minimum threshold. Temps are currently holding steady in the mid 20s, which is a fair bit below what was forecasted by the NWS. That could portend a later switch to plain rain, or it could mean absolutely nothing. Upstream OBS will be important to make that determination later today. Towards the medium range, if you're bellyaching about the lack of storms to start our colder pattern then there's good news for you: the ensembles look potentially more active towards the second week of January with the mean trough axis retrograding west and more low centers showing up in the member spreads.

    2. 2.0" is the official number by midnight last night. So it looks like they recorded another 0.2 since midnight. Still more than 50% less than the previous record set in 2006 of 4.8.

    "There are ensemble hints of more of a west coast ridging tendency going towards the new year. It's a baby step since we still have no blocking and Alaska is still awash with troughing, but then no one said this would be an easy transition process."

    Carol Cheryl Cristal Cherlene December 17, 2015 at 4:49 PM:

    "Sounds like the EPS mean is also on board with a change to ridging in the west. So it's still early but it seems there's now a door opening from the current garbage pattern to one that's less garbage. The Euro weekly updates this evening, we'll see if it also agrees."

  33. Cohen:

    "-The AO is currently weakly positive and is predicted to trend negative into negative territory starting next week.

    -The negative AO trend is reflective of the model forecast of initial low pressure/geopotential heights over the North Atlantic side of the Arctic transitioning to more high pressure/geopotential heights over the entire Arctic basin. The models are predicting two regions of strong geopotential height rises one across northwestern Siberia and the Barents Kara Seas and the other across Alaska and northwest Canada. This has significant implications for the strength of the polar vortex in January.

    -With high pressure strengthening in the Barents Kara seas, temperatures should turn cold first across Western Siberia and become more expansive with time. The models predict that first the cold air will expand westward toward Eastern Europe and then eastward across all of Siberia and eventually East Asia as well. How much of the cold air will reach Western Europe will likely depend on how much of the positive geopotential height anomalies will bridge across towards Greenland.

    -Similarly, rising pressure/geopotential heights across western North America will result in deepening troughing across eastern North America and a cooling trend in temperatures for the Eastern United States.

    -One strong pulse of energy transfer from the troposphere to the stratosphere that just ended over the weekend has perturbed the polar vortex and has helped to initiate the cooling across the mid-latitudes. The models are predicting a second pulse during the first week of January and we continue to anticipate even further energy transfer. This will continue to perturb or disturb the polar vortex further, which will likely peak sometime in January.

    -High snow cover and low sea ice this past fall favored a weakening of the polar vortex preferentially in January. Perturbing of the polar vortex is underway and in our opinion, the predicted hemispheric circulation pattern favors further weakening of the polar vortex. Following a weakened polar vortex, the negative phase of the AO, cold temperatures and potentially an increase in snowstorms is favored across the Northern Hemisphere mid-latitudes including the Eastern United States, Europe and East Asia."

    The PV will be getting the taffy puller treatment over the next ten days:

  35. As far as I recall, a winter pattern wasn't likely until at least mid January. This was mentioned a few weeks ago. If we get to the end of January and winter is nowhere tobe seen, it might be towel throwing in time.

  36. 60's are gone till spring. 50's probably gone as well. 40's will be infrequent. 30's more the norm for day time highs. Maybe not typically Jan weather on the way, but a HUGE shift from where we've been.

    As I've been saying for close to two weeks, the trend is your friend, if you like winter weather.

    ReplyDelete
    Replies
    1. and with temps mostly in the 30's for daytime highs and 20's for lows, we are going to be far more likely to see snow starting early Jan than where we were in December.

  37. To those sounding the alarm, we literally just had the torch pattern break down in the past 72 hours, a pattern we have been in for almost an entire month. Models are not all of the sudden going to start lighting up with storm systems, especially with weak tele's right now. In addition, it's going to take some time for models to hop off the el nino bias. I believe CCCC alluded to the fact that the pattern will become more supportive for larger scale systems beginning next week, and I have to agree with him. With an ample supply of cold air and tele's finally beginning to trend in our favor(especially PNA, AO, and even MJO wheeling into phase 7 now that el nino has weakened), models will begin showing much more favorable conditions for snow. If you're going to look at models run to run, you need to look at means and spreads for anything over 5 days out with so many atmospheric variables changing. As the great Aaron Rodgers said last year, R-E-L-A-X, relax...

    P.S, everyone is at risk of seeing a burst of snow this weekend as signs are pointing towards an arctic front moving through.

  52. Having a pronounced northerly component can actually be detrimental to heavy amounts. We want a well-aligned 300-310 flow to get a contribution from Georgian Bay. Too far past 310 and that contribution starts to shift west of Rochester, and we're left with lighter snows off of a short fetch.

      I don't live there, but own a place in NE Oswego County. I'll be up there this weekend. Trust me, that much snow gets old quick. One has to rake the roof...a lot of fun with the snow on the ground up to your waist...and buildings can collapse without such maintenance...it cost three times as much to have your parking areas plowed out compared to here...snowblowers are overwhelmed by the amount of snow...roads can be impassible for many hours, sometimes days in heavy lake effect events...outdoor activities including snowshoeing and cross country skiing are much more difficult...4WD vehicles practically a necessity. There is a reason why that area never was permanently settled. Don't get me wrong, I appreciate the snow for snowmobiling, but IT IS A LOT OF WORK to live and/or own property with structures on them up there. OCCASIONAL large snow events, typical for this area, are much more manageable and tolerable.

  56. I believe we will have advisory lake snow on Sunday night and Monday. Some with the arctic front pushing that lake Ontario band south over us and then squalls on Monday. 4-8 inches not out of the question. Not a lot but more than we have seen so far in this wimpy winter.

    ReplyDelete
  57. There are two specific time frames that I'm looking at for possible storm activity. The first is January 8-10th, which right now looks like the lesser opportunity. The second is January 11-13th, which I like better at the moment owing to a more favorable longwave trough position and ensemble MSLP spread. Naturally it's far too soon to begin discussing whether a storm will even exist during either time frame, let alone if we'll get any snow from them. These are windows of opportunity and nothing more.

    Once again I'll be gone for a few days, this time fore New Years shenanigans in Connecticut. I hope to be greeted by lake snow headlines when I get back.

Actually counted no fewer than 4 organized storm systems on the most recent GFS run, and a quick glance at the earlier runs yields about 3-5 on average. Pretty much a minefield of low centers in the ensembles...some are clippers and some are larger systems. No more talk of snow futility records unless we somehow completely dodge every decent snow opportunity through the 21st.

  69. We are finally going to get some snow. I just wish it was not going to be back in the 40's by weeks end. Lets enjoy the snow while we have it.

    1. Not going to be much Snowdog. The ingredients are not present for good LES in any areas. Maybe an inch or two by Monday in most areas.

  70. The only ingredient we lack is an upper lakes connection. If we had that then there would be a warning instead of an advisory. As it is I can see 2-4 inches for most.

  71. This is what the NWS is saying:

    "BY SUNDAY EVENING...WINDS WILL BE PREDOMINANTLY FROM 320-330 DEGREES WITH 850MB TEMPS FALLING FROM -10C SUNDAY MORNING TO -14C BY SUNDAY EVENING AND -20C BY MONDAY MORNING. LAKE SNOWS WILL BE REDIRECTED TO THE SOUTH SHORES OF THE LAKES AND ALTHOUGH THE COLD LAYER WILL BE VERY SHALLOW...LESS THAN 3KFT FOR MOST OF THE TIME...AN ISOTHERMAL LAYER ABOVE THE BOUNDARY LAYER WILL PERMIT EQUILIBRIUM LEVELS OF 6KFT TO 7KFT TO BUILD THE DEPTH OF EACH LAKE SNOW CELL. WELL ALIGNED MEAN LAYER FLOW AT 15 TO 20 KNOTS SHOULD PRODUCE DISCRETE BANDS OF LAKE EFFECT SNOW...STREETS OF CLOUDS...WITH ON AND OFF SNOWY CONDITIONS SUNDAY NIGHT THROUGH MONDAY AFTERNOON. THE BOUNDARY LAYER DRIES MORE WITH A STRONGER SUBSIDENCE INVERSION BY MONDAY EVENING WHICH SHOULD REDUCE THE LAKE EFFECT SNOWS BUT MAINTAIN THE LAKE EFFECT CLOUDS INTO TUESDAY."
