To ease into the new week I thought I’d include a few interesting maps. The first is a very detailed map of rainfall totals from last year. I’ve mentioned that it was a very wet year for Syracuse but this map really shows how the totals for the year varied across the area:

This comes from the National Weather Service in Binghamton so that’s why you don’t see totals from north of Syracuse over Oswego, Wayne and Northern Cayuga Counties. If you want to see a bigger map go to this web site. Not only will get a bigger version of the map above but also some monthly rain totals by city.

Also, I wanted to include these next two maps that show snow cover right now and one from a year ago.

The difference is quite dramatic as parts of Oswego county had over 2 feet of snow on the ground and in Syracuse we had almost a foot of snow a year ago on this date.

This last full week of January does look relatively tame weather wise with very few chances to add to the snow pack. There is potential for some very minor lake effect Tuesday and Tuesday night, mainly east of the lake over the Tug Hill Plateau. However, don’t be surprised if some snow showers sneak south into the Syracuse area later Tuesday and very early Wednesday. Again, this doesn’t look to be a major event (the air aloft is just not that cold) and for most it will be on the order of a couple inches or less of accumulation.

Next up is a system in the later Thursday to Friday time frame. There are two pieces to this puzzle, one part moving out of the Southwest into the Gulf Coast region by early Thursday the other a front and low pressure dropping south out of Canada into the Great Lakes. A lot will depend on the timing of these systems and how they interact with each other but right now temperatures look to be borderline so we’ve got rain and wet snow in the forecast.

The lake effect potential does increase heading into the weekend and that could make for the most impactful weather of this upcoming week. Behind whatever forms Thursday night and Friday it will start to bring some chilly air from Canada. Signs point to the air over us being cold enough for lake effect as early as Saturday afternoon then becoming colder still into Sunday.

This means the potential for lake effect will increase as we go through the weekend. Of course the real trick will be forecasting where the winds will set up. More on this as the weekend gets closer.
