A line of strong thunderstorms moved across New Brunswick, western Prince Edward Island and eastern Nova Scotia on Saturday bringing heavy downpours, hail and strong winds.

Greater Moncton was under a severe thunderstorm warning for a few hours with hail about 1 cm in diameter being reported outside the city.

Heavy rain also caused flash flooding in downtown Shediac with social media posts showing vehicles making their way through water clogged streets.

Temperatures also plunged from the low 20s to the mid-teens as the storms passed.

Although the rain is needed, concert goers might disagree with the first show being staged on Magnetic Hill today in four years.

Severe weather moves across N.B.

A line of severe thunderstorms slid through New Brunswick tonight producing heavy rain, hail and strong, gusty winds up to 100 km/h.

Small funnel clouds were noticed but no reports of tornadoes.

Environment Canada issued watches and warnings for many parts of the province including Greater Moncton.

The ridge of storm clouds passed to the northwest of the city and not a single drop of rain fell but it did drop temperatures enough to end the heat warning.

Days of severe weather including heavy rain, thunderstorms, hail, tornadoes and flooding led officials in western Alberta to declare a state of emergency.

However, Yellowhead County (west of Edmonton) dropped the declaration on Wednesday when floodwaters receded.

Many roads had to be closed or were made impassable after flooding and drivers were being asked to obey any barriers in place.

Residents were being warned about possible contamination of their drinking water.

Yellowhead County officials say at least 25 homes were directly impacted by floodwaters.

Freak hailstorm in western Mexico

Guadalajara was inundated with almost one metre of hail when a freak hailstorm moved through parts of Jalisco state on Sunday.

The governor posted photos on social media of buried vehicles, damaged homes and city workers alongside the Mexican Army shoveling the hail – even bulldozing it.

No reports of injuries or fatalities.

At 1,600 metres (5,000 feet) above sea level, meteorologists say high elevation played a role as one thunderstorm moved out and another one developed rapidly behind it bringing a huge quantity of small hailstones.

Severe weather in Manitoba, NW Ontario

After a hot and windy day across southern Manitoba, severe thunderstorms developed late Friday afternoon with heavy rain, hail and lightning strikes causing at least one grass fire.

Daytime highs soared to 36.6°C in Winnipeg and 37.3°C in Carman which was the hot spot in Canada.

Temperatures dropped dramatically after the storms rolled through and damaging winds up to 100 km/h were reported in some areas along with nickel-sized hail.

The heat and thunderstorms moved east into northwestern Ontario with Kenora reaching 33.0°C yesterday and Armstrong climbing to 32.3°C today.

Tornado hits National Capital Region

 

A tornado developed about 10 kilometres southeast of Gatineau Airport, Quebec early Sunday evening.

The tornado moved east along the Ottawa River before coming ashore on the Ontario side.

In the suburban Ottawa neighbourhood of Orléans, strong winds brought down trees and removed shingles on many homes with one person reportedly injured.

A thunderstorm also produced 2 centimetre hail in the area.

Environment Canada says the tornado was a low end EF-1 suggesting peak winds of 135 km/h and had a path length of at least 25 kilometres.

Hail Calgary!

It looked like a snowstorm in July as violent thunderstorms rolled across southern Alberta on Monday covering Calgary in golf ball-sized hail.

Traffic was snarled during the afternoon commute as drivers coped with hail piling up like snow.

By early evening, the storms had passed and Environment Canada dropped severe thunderstorm warnings for the region.

Calgary is dubbed the hailstorm capital of Canada and south central Alberta is known to be one of the worst areas of the world for thunderstorms producing damaging hail.

Heat wave abruptly ends in N.B.

The temperature climbed to 30 C for three days in a row in Greater Moncton which is an unofficial heat wave since 32 C is the maximum by definition.

Those warm daytime highs, 30.4 C (19 July), 30.4 C (20 July) and 30.0 C (21 July), still haven’t eclipsed the season-to-date maximum of 30.8 C recorded on 11 June.

A cold front moved west to east through New Brunswick yesterday triggering scattered thunderstorms with heavy rain, gusty winds and even hail.

The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

Severe weather in northern N.B.

An unstable air mass moved from west to east in New Brunswick producing severe thunderstorms bringing torrential rain, large hail and strong winds.

Environment Canada believes a severe thunderstorm formed near Doaktown and possibly spawned a tornado that moved into the Blackville area last night.

Golf ball size hail and damaging winds with gusts up to 100 km/h were recorded in the Plaster Rock area.

Southeast New Brunswick has seen an above average 18 days with thunderstorm activity this June and a severe thunderstorm watch was issued in the region this afternoon.

Heat comes to abrupt end

After three days of daytime highs above 28 C in Greater Moncton, much cooler weather is coming thanks to a cold front and a change in wind direction. 

The warm sometimes unstable air mass has created severe thunderstorms across the region.

Flash flooding was reported in Saint John yesterday after heavy downpours with wind and hail which were also observed today in northeastern Nova Scotia. 

Environment Canada is forecasting below seasonal temperatures for Southeast New Brunswick over the next couple of days.
