ECCC's Manitoba crew/Twitter account on-board with the forecast....Brandon in that 10-15cm zone by wakeup on Friday:
Can take a little solace in being not too far from the 5-10cm zone. Not clear if that area is forecast lower because of expected system track, or if it's accounting for the impact elevation/terrain can have or all of the above but I dont imagine there's any harm in hoping that lighter area slides just a little to the Northeast :)
They also give an idea of just how big the wind gusts with the system are expected to be:
and for a little more technical look at what's forecast, this paste comes from the Prairie and Arctic Storm Prediction Centre's Tuesday afternoon update (see link for the whole thing):
"SK/MB...FAIR WEATHER TODAY. THIS CHANGES TONIGHT AS THE LOW OFF THE
WEST COAST EJECTS AN IMPULSE WHICH DEVELOPS A LOW OVER ALBERTA.
THIS LOW PROCEEDS TO TRACK THROUGH SOUTHERN SK/MB ON WED/THUR,
BRINGING THE FIRST WINTER STORM OF THE SEASON. MILDER AIR/GROUND
TEMPERATURES WILL LIMIT SNOWFALL ACCUMULATION AT FIRST, BUT
EVENTUALLY THE SNOW WILL WIN OUT. SK SHOULD ESCAPE THE WORST, WITH A
BAND OF PERHAPS 5-10 CM ACCUMULATION BY FRIDAY MORNING, BUT THE STORM
REALLY HITS IT'S STRIDE AS IT MOVES THROUGH MANITOBA, WITH INCREASED
SNOW RATES, LOWER TEMPERATURES AND HIGHER SLR VALUES. WIDESPREAD
ACCUMULATIONS OF 10-20 CM CAN BE EXPECTED THROUGH MUCH OF SOUTHERN MB
BY FRIDAY MORNING, WITH GREATER AMOUNTS OVER HIGHER TERRAIN AND
DOWNWIND OF THE MANITOBA LAKES, WHICH ARE EXPECTED TO ENHANCE
SNOWFALL AMOUNTS. THE PARKLANDS REGION OF WESTERN MANITOBA WILL BE
HARDEST HIT, WITH UP TO 50 CM POSSIBLE OVER THE HIGHER TERRAIN. "
