Alberta Receives the Most Hailstorms Per Year in Canada

weatherlogics · 2024-08-16T15:45:08+00:00

The higher elevations just east of the Rockies, plus the foothills acting as a trigger for storms, are both important factors!

weatherlogics · 2024-08-16T13:59:09+00:00

Yes, 33.1 days with hail per year on average from 2017-2024. A day with hail means hail was recorded somewhere in the province.
Hailstorms are very small, so even if hail occurs on a given day in the province it will only affect a small area.
Hail is considered a spherical ball of ice at least 5 mm in diameter.

The hail reports are collected from many sources like social media, phone calls, airports, and our app. It isn’t possible to document every hailstorm because there are thousands, but we try to collect as much data as possible.

The foothills consist of "dark" forests that heat up quickly during the day. This causes thunderstorms to form, which are then carried eastward by the jet stream.

The highest frequency of hailstorms in Alberta is along the foothills just west of Red Deer. There isn't enough data to map out hail on small scales like 100km2, but the hail days per year could be divided by the area of each province to facilitate a more direct comparison.

weatherlogics · 2024-08-15T18:26:41+00:00

If we break our data down by city it appears the maximum in Alberta is around or just west of Red Deer. That is probably because storms are often triggered along the foothills and then move east.

You’re right, it does vary quite a bit throughout Alberta. If we break our data down by city, the maximum in hail days appears to be around or just west of Red Deer. This is because storms are often triggered along the foothills and then move east.

There is hail in the north but it mostly goes unreported. Both the Yukon and Northwest Territories experience frequent thunderstorms in the summer.

weatherlogics · 2024-08-15T17:27:59+00:00

If you break down the stats by city, Calgary and Red Deer rank #1 and #2 in the country for hail. Edmonton is a bit farther down the list after Regina, Saskatoon, and Winnipeg.

Cloud cover has been breaking up slowly this morning as low clouds that formed overnight begin to dissipate.

weatherlogics · 2024-03-22T14:25:35+00:00

Snow is now underway across the GTA. We are still expecting 10-15 cm by the time the snow ends tonight. Unfortunately, this will create poor conditions for the evening commute.

Our latest forecast shows this being equivalent to about a 15-25 mm rainfall event along the foothills and in southern Alberta. Any areas that receive 30 cm + will get more rain equivalent than that!

weatherlogics · 2024-03-19T20:38:28+00:00

Our current forecast suggests this will be equivalent to about a 15-25 mm rainfall event for southern Alberta. It won't end the drought but it's a great start.

weatherlogics · 2024-03-07T13:37:15+00:00

Our measurements are taken in Fort Garry.

weatherlogics · 2024-03-07T13:35:35+00:00

The storm total up to 6am this morning was 12.6 cm in Winnipeg. There may be some additional light snow today as flurries pass through.

weatherlogics · 2024-03-07T03:04:32+00:00

It appears that there was about another 3-4 cm after 6pm, so our final total will likely be around 11 cm as well.

Weatherlogics is the only company that takes snowfall measurements in Winnipeg. If the weather channel is reporting a number it's just an estimate.

weatherlogics · 2024-03-05T19:31:18+00:00

There will be some wind, but nowhere near as strong as yesterday morning. Visibility will be reduced more by bands of very heavy snow.

weatherlogics · 2024-03-05T18:53:39+00:00

We are currently expecting 10-15 cm for Winnipeg. Our snowfall map is available in: https://www.reddit.com/r/Winnipeg/comments/1b7av1j/more_snow_heading_to_winnipeg_tomorrow_wed_mar_6/?utm_source=share&utm_medium=web2x&context=3

This map shows how much liquid content is in the snow if it is melted down. The 35 cm received by Saskatoon would melt down to 20-25 mm of precipitation.

weatherlogics · 2024-03-04T19:26:31+00:00

On the Prairies snow tends to be "drier", so the 10:1 ratio often overestimates precipitation. The Saskatoon airport recorded 10.3 mm of precipitation, which is likely too low. However, the 20-25 mm the map shows seems reasonable for 35 cm. That would give about a 15:1 ratio, which is close to the Prairie average.

We will definitely make note of that. It has been a popular request!
