If Chicago manages to get yet another winter storm (which would be 3) in what should be an otherwise "crappy" season with this closed low, while Detroit and Toronto has YET to even see a storm greater than 3" (let along an advisory or warning criteria event), I seriously give the f*ck up on this winter. And this is after they've come off a season with a historic nearly 2' blizzard. I don't even want to hear the crap about the final seasonal totals. What's more important IMO is how one reaches their seasonal totals. If one ends up with an above average season with no winter storm then it would leave much to be desired.

Not even a EPIC blizzard and/or snow dump (1,000,000 to 1 odds) would repair the wounds of this season at that point (it would heal them some, but not completely).

And it wouldn't be as disappointing either if we weren't getting to the point in the season where one needs either the snow to fall in the nighttime or significant snowfall rates/snowflake size for the snow to actually accumulate and/or if there was actually a REAL pattern change in the offing sooner rather than after the next 2-3 weeks (because remind you, the Plains must do some HEFTY catching up first so we can try to sustain whatever cold air advects overhead in the first place).

The only bright "Misery loves company" side to this winter is it's disappointing for every type of winter weather lover (snowstorm fans and snowcover fans).

Reading between the lines in the New England subforum, it looks like the 12z Euro brings some decent cold air into the Midwest around Day 7-8.

Maybe the 15th time will be the charm...

It is much colder in the D7-9 period than it has been. By D10 it looks like the warmth is ready to invade from the Plains, but with a strong -NAO signature (strongest I've seen this season), most of that warmth would get shunted to the S & W.

Problem is that the OP EURO has not been very consistent beyond D7. If the EURO ensembles don't budge I'd ride them like I'd ride Brooke Shields circa 1980.

Wow, what an interesting day. Was very foggy all morning with a coating of rime on about everything exposed outside. Looked very cool. The fog quickly lifted around noon and everything melted. This was all when I was at work. I left work about 45min ago and as I drove northeast it went from 10 mile visibility to about 1/4 mile over the course of a mile or two. Very foggy here at home and it looks like the temp never made it out of the mid 30s.

Fog is back here, 34°. Probably get a coating of rime tonight. Expected low is 29˜.

Considering fog basically acts as a refrigerator makes me think things could get colder than expected when the fog really gets going.

Radiation is lost to space at the top of the fog since water vapor emits radiation, and none is gained. This leads to penetrative cold downdrafts that mix throughout the fog layer.

Good explanation! Have to see what the temperature trend is tonight. Definitely a damp, cold evening. Visibility is still around 4.0 miles.

NWS here in La Crosse had this today:

BEYOND THIS TIME PERIOD...THE MODELS CONTINUE TO STRUGGLE AS A

MODERATE TO STRONG NEGATIVE ARCTIC OSCILLATION DEVELOPS. THIS

WILL RESULT IN THE DEVELOPMENT OF AN AMPLIFIED TROUGH ACROSS

EASTERN CANADA...GREAT LAKES...AND NEW ENGLAND. THE MODELS

CONTINUE TO SHOW THAT THE ARCTIC AIR ASSOCIATED WITH THIS LONG

WAVE TROUGH WILL EITHER JUST BRIEFLY MOVE THROUGH THE AREA OR

REMAIN TO OUR EAST. THIS ACTUALLY FITS IN WELL WITH A COMPOSITE

ANALYSIS WHICH SHOWS NO STRONG STATISTICAL SIGNAL BETWEEN THE

PHASE OF THE ARCTIC OSCILLATION AND THE AVERAGE FEBRUARY

TEMPERATURES FOR OUR AREA OF THE COUNTRY. THE WESTERN EXTENT OF

THIS TROUGH WILL BE GREATLY AFFECTED BY THE TELECONNECTION WITH THE

ANOMALOUS THUNDERSTORM ACTIVITY THAT IS CONTINUING TO OCCUR ACROSS

INDONESIA AND THE WESTERN PACIFIC. SINCE THIS CONVECTION IS VERY

SIMILAR TO WHAT WOULD BE SEEN IN PHASE 5. DURING THIS PHASE...LONG

WAVE TROUGHS TYPICALLY HAVE A HARD TIME MAINTAINING THEMSELVES

ACROSS THE MID AND UPPER MISSISSIPPI RIVER VALLEY. THIS IS IN

VERY GOOD AGREEMENT WITH THE CFS VERSION 2 WHICH HAS BEEN SHOWING

THIS SCENARIO CONSISTENTLY FOR THE PAST TWO WEEKS. FOR THE TIME

BEING...JUST COOLED THE TEMPERATURES TO EITHER SLIGHTLY BELOW OR

NEAR NORMAL FROM WEDNESDAY THROUGH THURSDAY.

Just checked my data from last winter season. At this point last season we were at 51.6". Currently sitting at 11.7", which is 39.9" less than last season to this point. We only received 5.1" more snow after this date last season. Of course last season's snowfall was well above average. If we were to receive the same amount of snow going forward as we did last season (which of course is very unlikely) we would total 16.8" for the season.

The GFS/GEFS, ECMWF MJO forecasts take it to Phase 8. Which would feature a trough in the east/ridge to our west. Probably leave this area kinda dry on the backside of a trough. We would have to wait until a progression into Phase 1 & 2 for better storms.
