Weather Discussion for Saturday March 5th 2011

A soggy Saturday for Southern Ontario with 25-40mm of rain expected today with up to 50mm possible in areas just north of the lake Erie shorelines.
Rainfall Warnings continue for all of Southern and Eastern Ontario.


 A stalled frontal  system is responsible for the higher amounts of rain across the region and as cooler air begins to move into the region later today and into the overnight, rain will change to snow. Current indications from the latest computer models suggest at least 5cm of snow from Windsor through to the GTA with slightly higher amounts north of their into Barrie and cottage country.

Precipitation will come to an end early Sunday morning and skies will clear later in the day.

Temperatures will go on a rollercoaster ride through the coming week along with a mixing of precip. Watching a system for Wednesday and another for Friday. The Wednesday system is looking like rain, however the Friday system currently looks like snow for most of Ontario with the exception of the extreme southwest of the province.
