Fall snowstorms in Alberta are not unheard of, but, snow "is" falling somewhere on this warm globe.

Snow, cold temperatures push into Alberta




October 2, 2012 — The calendar may still say fall, but parts of Alberta will be feeling a little more wintery this week.

Default Blizzard conditions Possible

National Weather Service Text Product Display

Grand Forks, ND

THE NEXT QUESTION WILL BE PRECIP TYPE. THE NAM AND ECMWF BOTH DROP
925MB TEMPS DOWN BELOW ZERO BY THE EARLY MORNING HOURS THURSDAY.
TEMPS ACROSS CANADA ARE NOT VERY COLD...BUT SOME DYNAMIC COOLING
IS POSSIBLE AS THE SYSTEM WRAPS UP. SREF PROBABILITIES OF PRECIP
TYPE HAVE SOME SNOW STARTING TO MIX IN AFTER 06Z THURSDAY. WILL
CONTINUE THE TREND OF SNOW MIXING IN LATE WEDNESDAY NIGHT AND
CONTINUING ON THURSDAY...WITH THE BEST CHANCES OF STAYING ALL RAIN
IN THE FAR SOUTH. THE NAM AND ECMWF...WITH THE COMMA HEAD OF THE
LOW CONTINUING OVER THE CWA FOR QUITE A WHILE...HAVE VERY LARGE
SNOW TOTALS. IN FACT...WITH THE QPF...LOW TEMPS AND STRONG WINDS
ON THE BACKSIDE OF THE LOW...IF THE ECMWF VERIFIES CONDITIONS WILL
BE NEAR BLIZZARD THURSDAY
. WILL HOLD OFF ON GOING THAT
CRAZY...BUT THINK THAT THERE WILL BE ENOUGH MODERATE TO HEAVY
PRECIP POSSIBLE TO BRING SOME ACCUMULATION DESPITE WARM SFC TEMPS.
INCLUDED SOME 2 TO 4 INCH ACCUMS MAINLY IN THE NORTH CENTRAL TO
NORTHEASTERN CWA FOR THE TIME BEING

Early Snows Not Unheard Of

The average 1" snow looks to be late October/ early November but the date wont be breaking records since earlier snowfalls have fallen. Not sure of more than 6" though.

But to answer your question... NO, its not normal.
