Well, it's something (from IND)...

UPPER LEVEL SHORT WAVE TRAVERSING OVER TOP OF THE RIDGE WILL

STRENGTHEN AS IT DROPS INTO THE GREAT LAKES ON SATURDAY AND SPIN UP

A SURFACE WAVE. MODELS CONTINUE TO WAFFLE A BIT ON TRACK AND TIMING

OF THE WAVE...BUT INDICATIONS STILL POINT TO GREATEST IMPACTS TO

CENTRAL INDIANA COMING SATURDAY AND SATURDAY EVENING. EVEN THOUGH

THERE ARE TRACK DIFFERENCES BETWEEN MODELS...THERE HAVE BEEN A

SOUTHWARD SHIFT FROM SUNDAY RUNS. HAVE EXPANDED THE RAIN/SNOW MIX TO

ENCOMPASS THE NORTHERN HALF OF THE FORECAST AREA SATURDAY AS A

RESULT WITH TEMPERATURES HOLDING INTO THE 30S. STILL EXPECT MAINLY

RAIN TO THE SOUTH WITH HIGHS IN THE UPPER 30S/LOWER 40S. PRECIPITATION

WILL LIKELY END AS LIGHT SNOW SATURDAY EVENING.

Hoosier had no reply for you :(

Euro actually throws light accumulating precip all the way back this way.. Just saying :arrowhead:

lol, haven't really looked at it too much. I'm sure there will be some potential since the airmass coming in is pretty cold...that isn't the only factor of course.

From Cincy:

12Z ECMWF AND CANADIAN IN GOOD AGREEMENT IN BRINGING A SUBSTANTIAL

SHORT WAVE OUT OF THE NORTHERN PLAINS AND THROUGH THE OHIO VALLEY AT

THE END OF THE WEEK. THE ECMWF HAS BEEN FAIRLY CONSISTENT WITH THIS

FEATURE. MEANWHILE THE OPERATIONAL GFS RUNS OVER THE PAST FEW DAYS

HAVE NOT HAD THIS OR HAVE BEEN EXTREMELY WEAK. HOWEVER THE 12Z GEFS

DOES OFFER SOME SUPPORT TO THE FORMER. GIVEN REASONABLY GOOD

CONTINUITY IN THE ECMWF SOLUTION AND ITS STRONG SUPPORT FROM THE

CANADIAN HAVE RELIED HEAVILY ON IT. THUS EXPECT PRECIPITATION TO

BEGIN SPREADING EAST ACROSS THE FORECAST AREA LATE FRIDAY NIGHT AND

OCCUR THROUGH SATURDAY AND INTO SATURDAY NIGHT BEFORE TAPERING OFF.

PRECIPITATION TYPE WILL BE A BIT TRICKY. AT THIS POINT IT APPEARS

THAT IT WILL BE ALL RAIN IN THE FAR SOUTH AND ALL SNOW IN THE FAR

NORTH WITH A TRANSITION ZONE IN BETWEEN. THIS WILL CHANGE OVER TO

SNOW EVERYWHERE SATURDAY NIGHT BEFORE ENDING.

HIGH PRESSURE WILL BUILD IN SUNDAY AND MONDAY. THIS WILL REINFORCE

COLD AIR WITH READINGS FORECAST TO BE BELOW NORMAL THROUGHOUT THE

LONG TERM.-- End Changed Discussion --

For those in southern Ontario/Toronto, Environment Canada is calling for periods of snow on Wednesday, likely from the secondary low development across PA/NY state. The 12z RGEM is strongly hinting at this.

Maybe we see a flake. Maybe.

And it looks like a 2009-10 redux the next week to 10 days as every type of snow producing system gets deflected to our SW. It'll turn around for us one day.

I was just looking at the EURO and GEM for this fri night/sat system....I know I was good luck for snow threads a few years back...should I start a thread for this? I will be out till around 9pm but can start it when it get home? let me know guys.

GEM looks quite interesting and skilling was just mentioning it.

I was actually thinking about starting one, as I never did start a thread over at Eastern. You guys always beat me to it lol. Since you have the good luck thing going maybe it should be you.

Man we sure are a superstitious bunch of bastards here on the boards aren't we? :guitar:

It's only good luck if it snows in my backyard.
