Modest lake signal on the 12z GFS, taken verbatim. Surely if this thing slides to the east, there could be a lake event somewhere in Northern Indiana/Southwest Michigan (and other locals benefiting from a N-NW flow). Obviously nothing can be said until we get a lot closer to event time.

Did we have a white Christmas in 2005? I don't remember that at all, in fact I remember it pouring rain that Christmas! Maybe there was still snow on the ground... likewise in 2008. We had like 18" of snow a few days before Christmas but a ton of slush by Christmas day, because it turned to rain on Christmas Eve. :cry:

2002-2004 were glorious years though, especially 2002 and 2004 with the Christmas eve-day snowstorm in '02 and that big storm that dropped 6-12" or so over the area a couple days prior to Christmas in 2004. I think it was around zero on Christmas morning too.

You are correct. We had pouring rain in 2005, but still a solid, soggy snowcover (the rain did turn to slushy snow on Christmas Eve). Per the record books, THAT is a White Christmas, but snow showers swirling in the air but not sticking, or a snowstorm that begins after 7am, is not :lol:

2002 snowstorm lasted about 10pm Christmas Eve to 3pm Christmas Day

2003 snowfall lasted from 9pm Christmas Eve to 3pm Christmas Day

2004 snowstorm hit on 22/23rd

Meh, although some say we've been in the best spot for frequent 6-10" storms in the last 5 years, we're also just about the only place that hasn't seen a major 12"+ storm in much of the Northeast and Midwest (including places such as Milwaukee and Minneapolis, which some will say have had it worse than us).

So as long as we see a major 12"+ storm this year, I'll be perfectly satisfied with an overall lackluster winter.

We arent just about the only place who hasnt seen a widespread 12"+ storm in the last 5 years, but we are one of the few whose big daddy record is from so long ago.

From 2007-08 thru 2011-12 MSP had 7 storms of 6"+, DTW had 11. DTW also had much more snowfall in total. BUT DTWs biggest storm was under 11" and MSP had one over 16". Its all personal preference, if we had a winter with one major 12"+ storm but the rest of the winter sucked, youd STILL see tons of complaining (maybe not from you tho). Ive been on these boards too long and seen too many types of winters to prove this.

Euro verbatim shows around 5-6" over far southeastern/eastern MI, with very significant amounts over Ohio (12"+).

Not to mention a 1-4" snowfall early Christmas.

This would be perfect (and fwiw Id say euro verbatum is indicating a 2-5" type snow on Christmas). I would MIND missing Christmas snow if a 12"+ storm hit 2 days later, but Id take either or.

IWX AFD w/respect to next week:

LONG TERM

SATURDAY THROUGH THURSDAY...THE MAIN CHALLENGES THIS PERIOD ARE

DURING THE MIDDLE OF NEXT WEEK WHEN THERE IS THE POTENTIAL FOR

UNSETTLED WEATHER INCLUDING A CHANCE FOR MAINLY SNOW. FOR THIS

PACKAGE...OVERALL VERY POOR RUN TO RUN CONSISTENCY WITH MASS FIELDS

AMONG THE ECMWF AND GFS TENDING TO LOW CONFIDENCE IN THE FORECAST.

AT THIS POINT...FAVOR A GEM/CIPS ANALOG BLEND. THESE SOLUTIONS FAVOR

A MORE NORTHWEST TRACK OF THE SFC LOW...CLOSER TO THE UPPER LEVEL

SUPPORT. THE GFS IN THIS PATTERN TENDS TO INITIALLY TRACK THE SFC

LOW TOO FAR TO THE SOUTHEAST. THEREFORE...KEPT A HIGH CHANCE FOR

SNOW LATE WEDNESDAY INTO WEDNESDAY NIGHT. THERMAL PROFILES INDICATE

ALL SNOW DURING THIS PERIOD...SO WITH A MORE NORTHWEST TRACK AND

SUFFICIENTLY COLD TEMPERATURES ALOFT...FEEL THAT THERE IS A

REASONABLE CHANCE FOR ACCUMULATING SNOW. OTHERWISE...A WEAKER SYSTEM

WILL MOVE ACROSS THE AREA EARLY THIS WEEK WITH A CHANCE FOR A

RAIN/SNOW MIX MONDAY.

Just read LC's facebook post in regards to next weeks storm..

Says St. Louis to Chicago to Detroit for the best snows .. Then Indy to Cleveland to Buffalo and Toronto for ice issues.

Says things are still way up in the air though..

sounds like November 2006 type track, only shifted east about 200 miles

DTX being very vague about next week, but cant blame them this far out

THERE IS STILL LOTS OF UNCERTAINTY REGARDING THE SYSTEMS FOR NEXT

WEEK. 12Z GFS IS NOW RESULTING IN LITTLE TO NO PRECIPITATION ON

MONDAY NIGHT AND TUESDAY. THE NEXT MID-WEEK SYSTEM PASSES TO OUR

SOUTHEAST ONLY CLIPPING OUR EXTREME SOUTHEAST COUNTIES IN THE GFS

SOLUTION. ECMWF STILL HAS A MORE DEVELOPED SYSTEM TRACKING NORTH

FROM THE DEEP SOUTH ACROSS THE EASTERN GREAT LAKES MONDAY NIGHT AND

INTO CHRISTMAS DAY. THE ECMWF ALSO BRINGS A WELL ORGANIZED MID-WEEK

SYSTEM JUST TO OUR EAST POTENTIALLY BRINGING THE NEXT CHANCE FOR

SOME DECENT ACCUMULATIONS TO SOUTHEAST MICHIGAN. NOT ONLY ARE THE

MODELS INCONSISTENT WITH EACH OTHER...BUT THEY ARE ALSO INCONSISTENT

AMONG THEMSELVES OVER THE PAST FEW MODEL RUNS WITH THE EXCEPTION

BEING THE EURO BETWEEN THE PREVIOUS TWO RUNS. OVERALL...HAVE LEFT

SLIGHT CHANCE/LOW CHANCE POPS IN THE FORECAST FOR THE MONDAY NIGHT

THROUGH THURSDAY TIME PERIOD UNTIL WE BECOME MORE CERTAIN ABOUT WHAT

IS GOING TO HAPPEN WITH THESE SYSTEMS AND THERE IS BETTER SAMPLING

OF THE OVERALL PATTERN GOING INTO NEXT WEEK.

ILN's take on this storm.

AREA FORECAST DISCUSSION

NATIONAL WEATHER SERVICE WILMINGTON OH

432 PM EST THU DEC 20 2012

.LONG TERM /SUNDAY THROUGH THURSDAY/...

A CHALLENGING AND HIGHLY VARIABLE FCST PERIOD WITH TWO SYSTEMS TO

AFFECT THE CWA. FIRST SYSTEM FOR CHRISTMAS EVE HAS LITTLE IF ANY

WINTER POTENTIAL. LATEST GFS HAS WEAK SYSTEM MAINLY ACROSS THE FAR

SOUTH PORTIONS OF CWA WHILE ECMWF MORE POTENT. WILL GO WITH A BLEND

BUT TRENDING TOWARD THE ECMWF. WILL GO WITH HIGH CHANCE POPS FOR NOW

FOR MONDAY AND INTO MONDAY EVENING. BELIEVE ARRIVAL WILL BE LATE

ENOUGH FOR MAINLY RAIN WITH POSSIBLE BRIEF MIX MONDAY MORNING.

SHOULD BE MAINLY DRY FOR CHRISTMAS DAY. MODELS ALL DEVELOPING

SIGNIFICANT STORM SYSTEM FOR WEDNESDAY INTO EARLY THURSDAY. WHILE

CONFIDENCE IS FAIRLY HIGH OF A WINTER IMPACT ON THE CWA...MODELS

HAVE BEEN CHANGING ON PLACEMENT OF STORM AND THUS PRECIP TYPE AND

AMOUNT. PREVIOUS MODELS HAD SYSTEM TO THE WEST OF AREA BUT NOW HAVE

MOVED IT TO EAST. THIS HAS PUT CWA IN FAVORABLE SNOW OR MIX AREA AND

SIGNIFICANT WINTER STORM EVENT. IF MODELS TREND ANY FURTHER

EASTWARD...SOMEWHAT LESS SNOW AND WINTRY MIX WOULD OCCUR. WILL GO

WITH A RAIN/SNOW MIX FOR WEDNESDAY WITH THE UNCERTAINTY CHANGING TO

ALL SNOW WEDNESDAY NIGHT AND THURSDAY. HAVE BUMPED TEMPS DOWN MOST

OF LONG RAIN PERIOD ESPECIALLY WEDNESDAY AND THURSDAY. MAY NOT BE

LOW ENOUGH ON WEDNESDAY IF SNOW BECOMES PREDOMINANT WHICH COULD

CERTAINLY BE THE CASE IF CURRENT MODEL TRENDS CONTINUE.
