Active weather week ahead

For the first time in its 54 year history NASCAR had to postpone the Daytona 500 on Sunday due to heavy rain. More rain is forecast for central Florida today possibly delaying once again the scheduled 1pm start.

It looks like an active weather week to end February and start what is meteorological spring. While we are not expecting any big storms, we will have a chance for precipitation every second day into next weekend. We will start with this most recent storm that brought southern Quebec anywhere from 15-25cm of snow along with strong winds on Saturday and lots of blowing and drifting snow. In many ways it was the biggest storm of the winter thus far. In Vermont upslope snows dumped over 30 inches on Jay with 1-2 foot reports across the Green Mountains. In the lower elevations it was generally around 6 inches.

Today we have a clipper system moving across Ontario and into southern Quebec. A little light snow is forecast this afternoon into the overnight period with perhaps 5cm for Montreal. High pressure will build into the area for Tuesday before another storm from the northern plains arrives on Wednesday. A mix of snow and perhaps some freezing rain may occur with this next storm, with amounts generally in the 10cm range with precipitation lingering into Thursday. Friday will be fair with the third storm arriving for Saturday. This will likely be the strongest of the three, but also the warmest, so at this point we are looking at a rain event for southern Quebec. Temperatures are chilly this morning at -9C with a gusty wind making it feel colder. We will see highs of around -4C today.
