Another storm is upon us and taking aim at the Sudbury – North Bay area.  As the storm progress, it will draw in cold air and this area can expect somewhere around 15 – 20 cms.  Areas further south throughout Southern, Central and Eastern Ontario will remain all rain for the majority of the storm.  Areas from Bruce Peninsula across Central Ontario into the Ottawa valley could see the heaviest rain with 15 – 25 mm (.5 in to 1 in) possible.

Come early Thursday morning locations across South, Central and Eastern Ontario look to switch over to snow.  Some models had near 5 – 7 cm for Central Ontario to the Ottawa valley area, but I think the wet ground might keep it around a trace of snow. Here is a look of accumulated snow for Thursday from the GFS model:24-hr-snow

Behind this storm, here comes the cold air for Thursday night into Friday AM (in fahrenheit):air-temp-friday

Look ahead

A small system looks to move through Ontario Sunday night into Monday, with a mix of snow and rain.  However a larger Colorado Low is on the models for Thursday March 7th.  Depending on which model you believe, this will either be snow or rain for almost the same regions getting the storm today.

The GFS model is much further north:march-7-gfs

While the GEM model is much further south with snow for Southern Ontario:mrach-7-gem

The Euro model is a little closer to the GEM model.  This will have to be watched over the next couple days.

Behind that storm it looks cold again until around March 13th when it starts to moderate closer to normal, maybe slightly above.  The end of the month still looks murky.  I think it will remain close to normal however cooler periods still look possible.
