|Over 20 inches of snow fell in Rapid City, South Dakota on Tuesday. The storm is heading east towards Ontario by late Thursday.|
Meanwhile on the warm side of the storm the first heat of the year pushed northward into New Jersey and New York with highs in the low 80's including a record high of 85 in Newark. Boston reached into the low 70's before a sea breeze cooled it back into the lower 50's.
What does all this mean for Montreal? Well our unsettled week will continue with temperatures today around the 8C mark for a high. Some showers are possible with mostly cloudy skies. On Thursday the region will begin to feel the effects of the Colorado storm with winds increasing out of the northeast and a cold high of 1 or 2C. Wet snow is expected overnight into Friday across a wide area from Ottawa to Quebec City and portions of the St. Lawrence Valley. At this time is is a little early to nail down amounts, but some areas could see in excess of 15cm while others close to the US border may just have a very cold rain. In Ontario a winter storm watch is already in affect for the southwest where rain will mix with and change to freezing rain late Thursday with significant icing possible. Already lots of freezing rain along the path of this storm with trees and power lines down. We will need to tweak the forecast over the next 24-48 hours so stay tuned. Friday may be a no travel day in the area.
