Residents of northern British Columbia were shocked to wake up to snow this morning – an estimated 50 cm in some areas.

Environment Canada says cold Arctic air combined with moisture from the Pacific was responsible for the winter-like conditions in late summer.

Fort Nelson received a mix of rain and snow while higher elevations of 1,000 metres or more saw mainly snow.

Historical data shows measurable snow is likely in Fort Nelson in every month except July.

By contrast on Monday, Kamloops in the Okanagan Valley – about 1300 km south – reached a daytime high of 31°C.

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.

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.

Brief heat wave ends

In less than two hours, the temperature in Greater Moncton dropped from 31.1°C to 24.0°C late this afternoon – a difference of seven degrees.

A cold front moved through New Brunswick with thunderstorms marking an abrupt end to the summer’s first brief heat wave.

Environment Canada even issued a tornado warning for the Grand Lake area after a possible twister developed south of Boiestown.

The warning was lifted after 30 minutes and no damage or injuries were reported.

Record highs have been broken in a number of communities across the Maritimes.

Friday, 05 July:

  • Kouchibouguac NP, new record 31.1°C, old record 33.9°C from 1939
  • Grand Manan, new record 31.7°C, old record 30.0°C from 1999
  • Halifax Stanfield Airport, 32.7°C, old record 31.4°C from 2013

Greater Moncton was within a hair of breaking a record Saturday and Sunday it was the warmest on that date since 2013.

  • 05 July, high 34.0°C, record 34.2°C from 2018
  • 06 July, high 31.4°C, record 35.0°C from 1911

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.

Heavy rain hits Maritimes

Hello summer!

The summer solstice officially arrived in New Brunswick at 12:54 pm ADT and it was certainly welcome after a relentlessly cold spring.

Greater Moncton enjoyed 15 hours and 46 minutes of daylight today but unfortunately the sun didn’t make an appearance due to lots of clouds and heavy rain.

The sun is directly over the Tropic of Cancer and it will now begin moving south toward the equator which means days will get shorter – ever so slowly starting tomorrow.

As for summer weather predictions, The Weather Network is suggesting warmer than normal temperatures in July and into August with near normal precipitation.

Environment Canada is calling for near normal temperatures and near to slightly above normal precipitation.
