Active Weather Week

A slightly cooler but bright Monday morning across the region today as high pressure is in control. This will be short lived, as we are in for a very active weather week. Since my entry last week about so little snow, we have had close to 15cm of wet snow over several days. So much for the record books. We will add to that total this week with snow expected every night and a mix of rain and snow during the daylight hours. Temperatures will be mild, a couple of degrees either side of the freezing point region wide. Today low pressure over the Midwest has prompted heavy snow warnings for southwest Ontario and Winter Storm Warnings in Michigan and Indiana, where 10-20cm is forecast. This storm will slide east and become nearly stationary along the Eastern Seaboard. It will remain there the entire week perhaps even moving back west. This will result in moisture being fed west across New England and southern Quebec. Snow will begin Tuesday and mix with rain at times. We will have periods of snow right into Friday. Precipitation will range from steady at times to completely stopped at others. Amounts are difficult to estimate at this time, but anther 15cm is not out of the question. This weather will have to be monitored closely for the exact time frame when we are expecting the heavier snow. Right now it looks like Tuesday night into Wednesday morning and again late Thursday, advisories may be needed. Today will be the best travel day of the week.
