First -10°C low in the fall

First -10
Although it seems like really cold weather arrived earlier than usual, the chart above shows a drop of -10°C occurred on the same date last year in Greater Moncton – 14 November.

Over the last seven years, the temperature has gotten that cold between mid-November and early December.

The thermometer will likely sink to -15°C sometime later next month.

The last time it dropped that low in Southeast New Brunswick was 10 March.

First Below 0°C Daytime High

First Below 0
Cold, wintry weather seems to have arrived earlier this season in New Brunswick and Greater Moncton is no exception.

As shown above, the first below freezing daytime high was recorded on 09 November which makes it the earliest date in recent years.

In addition, the thermometer has already dropped to -10°C this month which I will outline in an upcoming post.

Sharp drop in temperature!

Temperature contrast 8pm, 12 Nov 2019 (earth nullschool.net)

Snow began falling in Southeast New Brunswick Monday night and later changed to freezing rain and then rain by Tuesday afternoon.

The temperature climbed to a balmy 14°C in Greater Moncton and 18°C in Greenwood, Nova Scotia.

But as the low pressure system moved out of the Maritimes toward Newfoundland, winds shifted to the northwest causing the thermometer to drop rapidly Tuesday night with a return to snow when it fell to freezing again.

Overnight low records could be challenged in the region by early Thursday as cold Arctic air takes hold.

Scattered frost!

It was a cold morning in the Maritimes and frost advisories were posted for all three provinces.

Scattered frost was recorded in many areas including Greater Moncton where the thermometer fell to -0.4°C at the airport which is close to the 2008 record low of -1.2°C.

However, a minimum of -4.4°C was set in the area in 1945.

This was a light frost and much earlier than the average date of 04 October.

June 2019 – Mild and wet

The average monthly temperature for June in Greater Moncton was at least close to normal compared to a damp, cold May.

While daytime highs climbed to 20°C or higher on 20 days, significant heat was scarce and the thermometer didn’t even get close to 30°C.

Rainfall was heavier than normal – a measurable amount was recorded on 21 days – following a trend which began in early spring.

About three-quarters of the precipitation fell during the last ten days of the month.

When will it reach 30°C?

First 30
It’s been a cold spring in Greater Moncton and the thermometer didn’t reach 20°C until 25 May – so when will it hit 30°C?

According to Environment Canada, the average date since 2013 has ranged from mid-May to late June but mainly late May.

While June has been warmer to date in Southeast New Brunswick, the long range forecast is calling for cooler conditions.

Will we have to wait until July this year?

May 2019 – Miserable!

Irishtown Nature Park, Moncton, 20 May 2019 (Dearing)

May 2019 proved to be the coldest May since 1974 in the Maritimes with temperatures about two or three degrees below normal.

The month started out with some warmth in Greater Moncton but it turned colder near the middle with snow recorded as late as the 21st before a slight recovery at the end.

Overnight lows were cold with six nights either at or below freezing and most minimums were in the low single digits.

Cold, damp and cloudy weather stunted growth and forced farmers to delay planting because fields were saturated.

Only three days reached or exceeded 20°C and the thermometer came nowhere near 30°C at any time of the month.

Warmest since early November!

The last day of March proved to be the warmest day in Greater Moncton since 03 November when the thermometer hit 17.1 C.

The daytime high reached a balmy 16.8 C and the New Brunswick hot spot was 19 C in Sussex which brought residents outdoors to walk, run, hike and play.

The maximum was actually close to the record for the date which was 17.5 C from 2006.

But a passing cold front will drop the temperature considerably overnight as rain changes to snow and Monday’s high struggles to reach slightly above freezing.

Spring arrives early in the North

A warm air mass has surged into Western Canada this week bringing record temperatures to the region and also to the North.

Many communities from Yukon to Nunavut were well above freezing and into the double digits breaking March records.

Yohin Lake hit a record high of 18.8°C Monday and spiked to 20.2°C Tuesday marking the first time in March the thermometer has climbed above 20°C in Northwest Territories.

Daytime highs in British Columbia’s Fraser Valley hit the mid 20’s while Alberta residents enjoyed maximums in the high teens.

January 2019 – Wet and wild!

The beginning of 2019 proved to be wild and crazy in New Brunswick.

Precipitation was well above normal for January as storm after storm brought rain, freezing rain, snow and ice pellets with rapidly fluctuating temperatures.

Ice and snow often blocked storm drains which created flooding during heavy rain and when the thermometer plunged, it all froze.

The average monthly temperature was actually about one degree above normal although it didn’t seem like it given the roller coaster of highs and lows.
