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.

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.

Here comes the heat!

After a cool and wet start to summer, a blast of heat is heading to the Maritime Provinces over the next few days.

Environment Canada has issued heat warnings for most of New Brunswick – excluding the Fundy coast – and western Nova Scotia while other areas under a special weather statement.

A warm, humid air mass is moving into the region today raising daytime temperatures to 30°C or more.

Humidex values near 40 are expected and overnight lows may not fall below 18°C providing little relief from the heat.

Near normal values will return late Saturday as a cold front arrives.

Heat warnings are also in place for parts of Ontario and Quebec where it climbed into the low 30s yesterday.

Calgary sets new heat record

Calgary hit an all-time record high on Friday when the thermometer climbed to 36.5°C which eclipsed the previous record of 36.1°C set 85 years ago.

Environment Canada had issued heat warnings for more than 100 regions in Alberta, British Columbia, Saskatchewan and Manitoba.

Besides the heat, smoke from forest fires have caused poor air quality throughout Western Canada.

A cold front lowered temperatures in Alberta to near seasonal values for the weekend but the heat lingered in the eastern Prairies.

The heat returns!

Another round of very warm temperatures and high humidity has enveloped almost all of the Maritimes with only New Brunswick’s Fundy coast exempt from an Environment Canada heat warning.

While actual daytime highs will approach 30 C, humidex values will range between 35 and 40 which can be dangerous for those at risk including young children, seniors and anyone with a chronic illness.

Forecasters say some relief may come on Thursday with some much needed rain but high humidity could persist until early next week.

Chris could pose threat

Chris

Atlantic Canada could feel an impact from Tropical Storm Chris which has formed off the coast of the Southeastern U.S.

The Canadian Hurricane Centre says the third named storm of 2018 will move northeastward and possibly strengthen to become a hurricane by early Wednesday.

The storm could weaken as it approaches Nova Scotia by Thursday.

The CHC notes there is still uncertainty in the forecast track and intensity of this system.

Beryl is the second named storm but first hurricane of the season and has been down downgraded to a tropical storm as it heads toward Puerto Rico.

Meantime, Environment Canada issued another heat warning for New Brunswick except the Fundy coast, Prince Edward Island and northern Nova Scotia as a warm, humid air mass pushes highs into the low 30s C with humidex values up to 38 on Monday.

Heat warning!

Record highs could be broken in Greater Moncton over the next couple of days if forecast highs in the low to mid 30s C are reached on Tuesday and Wednesday.

Environment Canada has issued a rare heat warning for New Brunswick, mainland Nova Scotia and Prince Edward Island with cooler conditions along the coast.

A warm, humid airmass is expected to push humidex values about 40 during the day and barely falling below 18 C at night – dangerous levels for those susceptible to heat.

Forecasters believe warm, humid weather will persist until later this week when a cold front brings temperatures closer to normal for the weekend.

Early fall heat

Aboiteau Beach, Cap-Pele, NB, 23 Sept 2017 (Dearing)

This may have been the first weekend of autumn in Southeast New Brunswick but it felt more like the first weekend of summer instead.

Greater Moncton climbed to 27.7 C yesterday (23 September) while today (24 September) it hit 27.9 C and the normal high for late September is 17 C.

High pressure and a northerly jet stream has pushed heat across Eastern Canada with highs in the low 30s C in many parts of Ontario and Southern Quebec.

A heat warning was in place as Toronto Pearson Airport reached a record-breaking 33.1 C yesterday and 33.6 C today.
