Severe weather moves across N.B.

Dark clouds northwest of Moncton, 31 July 2019 (Dearing)

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.

Heat building in the Maritimes

A heat warning has been in place since the start of the weekend in much of New Brunswick, Nova Scotia (except for Cape Breton) and Prince Edward Island.

In Greater Moncton, the temperature climbed to 30 C on Saturday and 29 C today but the forecast calls for 30 C on Monday and 31 C for Tuesday and Wednesday.

Overnight lows are not expected to drop that much either hovering around 18 to 19 C.

While humidity has been relatively low this weekend at around 50 percent or less, Environment Canada says the warm air mass will become more humid this week.

The only relief will be along the Fundy coast where temperatures will stay in the low 20s.

New all-time record highs across Europe

The second summer heat wave gripping Europe peaked on Thursday with new all-time record highs set in several countries.

Paris climbed to a stifling 42.6 C breaking the French capital’s previous record high of 40.4 C from July 1947.

The temperature climbed above 40 C in the Netherlands at Gilzen-Rijen for the first time ever when it reached 40.7 C and Lingen, Germany set a new country record of 42.6 C.

Records were also set in Belgium (41.8 C) and Luxembourg (40.8 C).

The UK Met Office is verifying whether a high of 38.7 C at Cambridge is the warmest temperature ever for the United Kingdom.

Historic heat in Western Europe

The jet stream has carried hot air from northern Africa across western Europe which is shattering all-time record highs in numerous countries.

The second extreme heat wave this summer has set new maximums in Belgium at 38.9 C, the Netherlands at 39.2 C and Germany at 40.5 C.

Bordeaux, France reached 41.2 C on Tuesday which was its highest temperature ever.

Thanks to the urban heat island effect, major cities are more prone to hot weather than rural areas and don’t cool down that much overnight.

On Thursday, the UK Met Office believes Britain could smash its current historic high of 38.5 C recorded in Faversham in August 2003.

Thunderstorms cool off Eastern Canada

Thunderstorms rolling across Southern Ontario and Southern Quebec this weekend brought an end to oppressive heat and humidity.

Toronto residents were trying to keep cool Saturday when the mercury soared to 33.0°C with a stifling humidex of 44 and Montreal reported similar conditions.

In the Maritimes, even typically cooler coastal areas were warm with new record highs set in Saint John and Grand Manan.

The temperature in Greater Moncton peaked at 32.4°C which fell short of the record of 33.5°C from 1991.

A brief, violent thunderstorm hit Halifax on Sunday afternoon with flash flooding and strong winds knocking out power to more than 44,000 Nova Scotians.

Hottest weather yet?

The next heat wave across Eastern Canada could be the warmest period yet this summer with daytime highs in the low 30’s C and humidex values near 40.

Southern Ontario and Southern Quebec have been blanketed with heat warnings from Environment Canada with hot, humid days and warm nights expected this weekend.

Temperatures in the Maritimes for Saturday and Sunday could reach 30 C but a cold front will bring cooler and drier air by Monday.

A mini heat wave already brought highs of 29 C and 30 C earlier this week in Greater Moncton.

Record heat at top of the world

The most northerly community in Canada – and the world for that matter – has set new all-time record highs for two days in a row.

Alert, Nunavut enjoyed the unusual heat thanks to a strong high pressure system over Greenland which moved into the Arctic Ocean.

Environment Canada notes Alert, population 62, normally sees highs of 6°C and lows of 1°C during July and more snow typically falls than rain.

Barry weakens after making landfall

Barry has been downgraded to a tropical depression after making landfall west of New Orleans on Saturday as a Category 1 hurricane.

Although Barry did not bring devastating flooding as some forecasters had originally thought similar to Hurricane Katrina in 2005, parts of Louisiana did receive more than 400 mm of rain which swamped the Mississippi River delta.

Emergency responders rescued at least 90 residents but there were no reports of fatalities.

Remnants of Barry have been moving northward with heavy rain across the American South up to the Midwest.

Louisiana braces for Barry

Tropical Storm Barry continues churning in the northern Gulf of Mexico with sustained winds of more than 100 km/h.

The U.S. National Hurricane Center says Barry is expected to make landfall as a hurricane along the coast of Louisiana on Saturday morning.

The city of New Orleans is on alert for heavy rain (up to 500 mm) and flooding along with storm surges although no evacuations have yet been ordered.

This is the first tropical system to impact the United States in 2019.

After landfall, Barry is expected to weaken and head northward through the Mississippi Valley.
