It looks like 2010 will be ending on a stormy note as a large storm system from the Pacific pushes into the central North America by mid week. This system will spawn two storm systems over the central plains that will affect southern MB beginning Wednesday night and continuing into New Year's Day. Significant snowfall and gusty winds will make for hazardous travel conditions over southern MB Thursday into New Years Day. The details..
Fair and mild conditions will prevail today and Wednesday with well above normal temperatures. Things however will begin to change Wednesday night as the first storm system begins to develop over the northern US Rockies. Snow from this system will spread into southern MB Wednesday night and intensify Thursday, along with increasing north winds. These winds will draw in much colder temperatures along with creating poor travel conditions in snow and blowing snow Thursday. Preliminary snowfall amounts from this system look to be in the 10-20 cm range across much of southern MB with the potential for locally higher amounts. Snow is expected to taper off overnight Thursday into Friday before another storm system intensifies over Minnesota by New Year's Eve. This system will track into NW Ontario and spread another area of snow and strong winds over southeastern MB New Years Eve into New Year's Day. There is still some uncertainty about the track of this second more intense storm system. If it tracks a little further east, southern MB will largely be spared from its worst effects. If it tracks a little further west however, it could bring blizzard-like conditions to the Red River valley for New Years Eve/Day. Whatever the case, the quiet tranquil weather of December will be coming to a stormy end as we close out 2010. Stay tuned on this developing winter weather situation.
