Heat wave abruptly ends in N.B.

Heavy rain during thunderstorm in NE Moncton, 21 July 2017 (Dearing)


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The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

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.

Winter won’t let go!

Still looks like winter in NE Moncton, 31 March 2017 (Dearing)

The temperature was warmer in the far north cities of Whitehorse and Yellowknife than it was in Greater Moncton.

The thermometer barely climbed above freezing today but at least the sun made an appearance after a five day absence.

Lots of cloud and frequent periods of snow have made the end of March look more like the beginning of January.

Environment Canada is not forecasting spring-like weather in the near future with another possible snowstorm by the middle of next week.

Blizzard warning downgraded

A low pressure system from Quebec tracking eastward into New Brunswick was originally expected to be a blizzard but Environment Canada downgraded that warning to a blowing snow advisory late today.

After reaching a high of 5 C by afternoon in Greater Moncton, the thermometer dropped below freezing by evening and rain changed to snow.

Strong, gusty winds will create blowing snow with 10 cm possible before conditions improve tomorrow.

Wind chills will be unseasonably cold over the next 24 hours with values as low as -27 C.

Snow falls in Caledonia Highlands

The early morning temperature on Saturday in Greater Moncton was -3.1 C which ties for the coldest yet this autumn.

Before the temperature fell overnight, there was a trace of rain but snow fell at higher elevations such as the Caledonia Highlands.

A couple of centimetres fell in the northern part of Fundy National Park, well away from the coast.

Spring turned out to be a rollercoaster ride in Southeast New Brunswick throughout the three month period with seemingly more clouds and rain than sun.

The trend continued almost until the first day of summer in Greater Moncton with consistent sun and warmth not until around the middle of the month.

June was actually about normal in temperature with slightly below normal precipitation – more than one third of the rainfall total fell in the last two days of the month.

First beach day of the season!

A warm, beautiful day in Greater Moncton was a great excuse to head to the beach.

Aboiteau Beach in Cap-Pele became my destination with a decent crowd for the Victoria Day weekend although the water was a bit chilly for swimming.

The temperature in Greater Moncton climbed to almost 28 C and likely a few degrees cooler along the coast but still the warmest day this spring and in 2016!

February proved to be milder than January in Greater Moncton – an above normal trend which began last fall thanks to what forecasters call a strong El Nino.

The temperature was often riding the weather rollercoaster with dramatic highs and lows within a 24 period.

Rainfall including freezing rain was higher than normal and although snowfall was heavy most of it fell during one event (38 cm) on 5 February.

El Nino has undoubtedly played a role in a milder than normal January in Southeast New Brunswick with less stormy conditions and below average snowfall.

Greater Moncton had three snow events during the month (3-4 Jan, 13 Jan, 29-30 Jan) which delivered 54 cm and typically about 78 cm falls.

The monthly average temperature was a relatively balmy -6.1 C which is roughly 2.8 degrees above normal.

Although it seemed relatively warm overall this October in Southeast New Brunswick, stats from Environment Canada show the average monthly temperature was actually below normal.

While daytime highs were mild, especially during the first half of the month, an autumn chill brought overnight lows well below freezing by late October dropping to a near record low of -6.2 C.

The fall foliage may have peaked a bit later this year – due to a dry late summer/early autumn – but strong winds from the remnants of Patricia brought down most leaves on the 29-30 October with gusts up to 82 km/h.
