Winter Storm Leon Final Forecast

A winter storm is currently moving in to Southern Ontario. The models had finally came to an agreement this close to the system and a general amount of snow is already set. This storm will produce a variety of wintery weather for Southern Ontario. 8-10 cm is expected for Southwestern Ontario changing into Freezing rain later overnight. 10-20cm is expected for South Central Ontario While 20-30cm is expected for South eastern and parts of central Ontario. The primary low of this system is expected to linger in the area longer and the duration of this system looks to be extended, thus the increased amount in Southeastern Ontario. Driving conditions will be terrible throughout Southern Ontario tommorow as a variety of wintery weather can cause many problems.

Forecasted Amount for selected cities:
Toronto 12-18 cm
Hamilton 10-15 cm
London 8-10 cm
Windsor - 5 cm
Barrie - 15-20 cm
Niagara Region - 10cm
Kingston - 15-25 cm
Ottawa - 22-30 cm
Sudbury - 12-17 cm

It is amazing how this storm is turning out like what I thought it would 4 days ago. It was definitely a fun storm to forecast.

It almost seemed like EC reads my blog, right after I complained about the amount they forecasted, they upped to 10-13 cm for Toronto! No warnings had been issued but it is definitely a good sign that all the models and forecasts starts to come into sync.

here is a timeline of what to expect in the GTA

midnight- light snow begins
midnight to 3am - moderate snow bands move in, 2cm on ground
3am t0 8am - snow at times heavy mixed with ice pellets, 5cm on ground
8am to 1pm - snow turns wet and light, mixed with ice pelletes and freezing drizzle 6cm on ground
1pm to 6pm - snow turns moderate again and continues to fall throughout the time frame, 9cm on ground
6pm to 10pm-snow at times heavy will get lighter throughout the evening 12cm on ground.
10pm to overnight- moderate to light snow 14cm on ground at the end of the period.

This storm will be quite long lasting as you can see as the low will stall around our region tomorrow.

Another snow storm will be moving in Friday night into Saturday for southern Ontario, this system will initially be a strong clipper, it will draw some moisture from the south by the time it gets to Southern Ontario. Most of Southern Ontario looks to be getting at least 8cm of snow possibly up to 20cm in some region. (GGEM shows 18-22cm right now). I will have more details on this and the complete forecast tommorow.
