April 25/56 – 20mm

Lots of rain!

It is going counter-clockwise,

This is ridiculous!

April 15

What a month! It was -3 last night.

Tiny hail:  graupel in Newfoundland. (Soft hail or snow pellets, too small to be called hail.)

Crews face hazardous conditions and significant damage such as broken poles, downed lines & trees as they work to restore power to over 42,000 customers.

Some of us have empathy for one another. Others, like my MPP, do not. He brags, stealing a photo of a tree down, with a power line under it.

April 15th – It is a mess. 

April 14 – 15 cm just snow!

April 13 – lots of rain, a bit of snow.

April 12th – 9mm

April 6th

We had 2 cm snow yesterday, but it melted.

April 5th – a horrible -10 C. this morning.

Still many without power across southern Ontario.

April 4th – 24 mm of snow, hail, ice pellets and lots of rain!

Careful out there with the high winds and blowing snow. Please keep two hands on the wheel, slow down and leave lots of space. We're on patrol for your safety regardless of the weather. #workingtogether #BeSafe pic.twitter.com/ymaHjjmILh

By the afternoon, more snow, more wind.
And more wind... at 6:00 p.m. 100,000 without power.

Thousands without power in the region, freezing rain and wind pulls down wires, some damage still not assessed. pic.twitter.com/WUAm0cSErK

The cats aren't too happy with our overnight -0 temperatures! No joke!

April precipitation

2016	15 cm snow
2015	84 mm
2014	160 mm

April 25 – rainy: 3mm

April 24 - Sunny day!

April 23 –flooding in Ontario

#MyParamedicDay was spent touching base with those affected by the flood. Sand bagging, like snow shoveling makes me nervous..#CardiacHealth pic.twitter.com/6Se5EhiO7x

April 21

More clouds!

April 20 – 8 mm!

April 19 - storms brewed up 7mm!

April 16th  Rain fell: 3.8mm

It came in two waves, more or less. 

April 15th – Rain approacheth: 9.7 mm

April 11th – Lots of cloud, little rain 1.8 mm

April 6th – 40+ mm rain, local flooding, with a topping of snow!

I melted the snowfall, only 2.3 mm of liquid.

We've had 74 mm over a few days. This was from the Texas tornado system moving our way.

The flooding is quite startling.

There were winds, and the resulting power outages. There is flooding across low-lying areas, too.

April 5th 

A months worth of rain coming in the next 2 days. With already saturated ground, some flooding is likely. pic.twitter.com/38PDW9BxiU

April 4th – AND, RAIN! We had 28.7 mm (~1+")

April 3rd – something's on its way!

April 1st

A bit of an April Fool's Day joke!
Eventually it all turned to snow fall, after a time. I measured the snow, but since so much melted, I used the rain gauge and we had 14mm of precipitation fall, over about 6 cm snow.
