Late October heat wave

Nine communities across New Brunswick set new record highs yesterday and the same will likely happen again today.

Greater Moncton was the warmest spot in the province climbing to 23.1 C which broke the old maximum temperature of 22.8 C from 1928.

Greenwood was among six communities in Nova Scotia breaking records with a high of 24.5 C.

Four records fell on Prince Edward Island including Charlottetown at 21.7 C.

Environment Canada says the Maritimes is enjoying a late October heat wave because the region is sandwiched between low pressure and high pressure allowing warm, southerly air to move northward.

Early fall heat

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.

Heat warnings issued in the West

Weather watches, warnings, statements re: heat and thunderstorms, 08 July 2017 (Environment Canada)

A strong ridge of high pressure over Western Canada has pushed the thermometer into record high territory for British Columbia and Alberta.

On 07 July, dozens of communities set new maximum temperatures with the highest at 39.4 C in Warfield and 38.3 C in Nelson but the hot spot in Canada was Garden River in northern Alberta at 40.3 C.

The major cities were warm too with Calgary reaching 33 C and Edmonton 30 C.

Heat warnings have been issued for most of Alberta and parts of Saskatchewan where temperatures will be near 29 C or higher for the next few days and residents are urged to take precautions.

Brief heat wave coming

A high pressure system is pushing warm, southerly air into the Maritimes with highs approaching 30 C tomorrow in New Brunswick.

Environment Canada says humidex values could climb to 39 which has led to a Level 1 Heat Alert for Fredericton and St. Stephen.

The provincial health department issues this alert when anyone vulnerable to the heat may be affected.

Greater Moncton could break a record on Thursday if the temperature reaches the forecast high of 28 C.

Gloomy weather will end

During the first half of June, rainfall was measured on 11 of 15 days in Greater Moncton according to Environment Canada.

Clouds came along with that rain which has meant only short bursts of sun during the mostly gloomy weather.

Hope is on the horizon since forecasters say that stubborn low pressure system will be replaced by high pressure and temperatures could hit 30 C by Sunday.

But not before a chilly night with either a frost advisory or a risk of frost for most of New Brunswick.

Where’s the heat?

Cloudy, cool, drizzle, showers and repeat.

If it was April we wouldn’t think twice but it’s mid-June and heat is currently absent in Southeast New Brunswick.

The daytime high in Greater Moncton was 12.2 C yesterday and the high today will struggle to reach 10 C.

Keep in mind, the average high for this time of year is 22 C and the low is 10 C.

A pesky low pressure system has no place to go thanks to a blocking high over Greenland so forecasters say cloudy, wet conditions will persist this week.

Widespread frost expected tonight

650x366_09181655_hd30Environment Canada has issued a frost advisory for a wide swath from Southern Ontario and Quebec to all of New Brunswick.

Temperatures are expected to fall to near freezing overnight in the south of the province to slightly below in the north thanks to an Arctic high pressure system.

To be on the safe side, I brought my plants inside from my patio tonight for the first time this season.

The forecast calls for a warming trend this weekend with highs in the low 20s C.

It may seem early – and it actually is for Greater Moncton – but a frost warning has been issued for all of New Brunswick tonight.

Gardeners should take precautions by either covering or heavily watering tender plants.

Environment Canada says a ridge of high pressure with clear skies and light winds will bring chilly overnight temperatures – possibly near the freezing point.

The average date for the first fall frost in Moncton is 27 September.

Record morning lows in NB

A high pressure system parked over Quebec has been bringing cold, dry Arctic air south to New Brunswick over the past few days.

Daytime highs in Greater Moncton have only been around 3 C which is several degrees below normal for early November.

In addition, early morning lows have been very cold dipping to -7.8 C today, just shy of the record of  -10.1 C from 2002.

Environment Canada shows new records were set this morning in Bouctouche at -7.3 C, Point Lepreau at -5.8 C and Alma at -5.5 C.

However, the cold spot was Edmundston at a frigid -12.2 C!

Hot Night!

Several cities in southern Ontario recorded their hottest nights ever as temperatures remained warm through today’s early morning hours.

Toronto, for example, fell overnight to a sticky 26.6 C, while the previous record for the hottest night came on Aug. 1, 2006, when the lowest overnight temperature was 26.3 C.

A hot, stationary high pressure area is creating a heat dome effect over central parts of Canada, pushing the jet stream well to the north, and keeping cooler or wetter weather away.

Environment Canada is forecasting highs of 34 C for Montreal and Ottawa, 38 C for Toronto and 39 C for Windsor, ON, which with the humidex will feel closer to 50 C.
