Coolest day since May

Irishtown Nature Park, 05 October 2019 (Dearing)

Chilly temperatures across the Maritimes on Friday made it feel more like early November than early October.

In Greater Moncton, the daytime high for 04 October was only 8.2 C which means it was the coolest day since 22 May when the maximum was only 8.6 C.

Halifax, Charlottetown, Saint John and Fredericton also had highs below 10 C.

The normal high for the first week of October in Southeast New Brunswick is 15 C with an overnight low of 4 C.

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?

Spring 2019 in review

Spring 2019
Meteorological spring in Southeast New Brunswick turned out to be colder and much wetter than normal compared to the 30-year average.

While March and April both had above normal temperatures, May was colder by a significant 2.4 degrees which brought down the overall seasonal average.

Rainfall was heavy in April and May and while snowfall was below normal for the three month period, the final snow flurries were spotted as late as 21 May.

Hurricane season begins

2018 hurricanes

Today marks the beginning of the 2019 hurricane season which will run until the end of November.

For a record fifth consecutive year, storm activity began before the 01 June official start date when Subtropical Storm Andrea formed on 20 May.

The U.S. National Oceanic and Atmospheric Administration (NOAA) is forecasting a near normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes.

The Canadian Hurricane Centre begins issuing statements when a storm is within three days of entering a response zone covering Eastern Canada and adjacent waters.

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.

Weather Network unveils summer forecast

TWN Summer 2019

After a cold and wet spring in New Brunswick, what will summer be like?

The Weather Network has unveiled its summer 2019 forecast and if you were hoping for warmer temperatures, it appears you may have to wait a little longer.

TWN suggests the season will be changeable and humid with cool weather in June but warmer than normal temperatures arriving in July stretching into August.

Extended periods of dry weather could lead to short term drought in parts of the Maritimes but overall precipitation will likely be near normal.

What about the spring 2019 forecast from The Weather Network?

TWN noted a cold wave in early March would be followed by a warmer pattern later in the month with more consistent spring-like weather by early April.

Both temperatures and precipitation were expected to be near normal.

So was the seasonal forecast accurate?

While early March was cold in Greater Moncton with a bitter low of -20.1 C, a warmer pattern never really developed except for a brief shot of warmth at month end.

April had some warmth in the middle but that fizzled near the end and while May started off strong, a cold pattern held steady for the second half of the month.

Precipitation was below seasonal in March, well above average in April and slightly above normal for May.

The Year Without Spring

It snowed overnight in Southeast New Brunswick.

About 0.6 cm of wet snow was recorded at the Greater Moncton Airport and even higher accumulations around the region.

In recent history, I can’t recall a snowfall this late in the month of May.

With meteorological summer arriving in 10 days and astronomical summer in barely a month, I’ve concluded that 2019 is the “Year Without Spring”.

The cold, damp weather has impacted farmers who are at least two weeks behind in planting crops due to saturated fields.

Sidewalk patios are eerily empty and winter parkas are still being worn by many.

A frost advisory has been posted for tonight and another one will likely be posted in two days as temperatures drop to near freezing again overnight.

Will the weather improve anytime soon?

A high of 20°C is forecast for Saturday but keep in mind we often hit 30°C before the beginning of June.

“Sprinter” continues

Sprinter is a portmanteau of spring and winter which aptly describes the recent weather in Southeast New Brunswick.

Already mid-May, Environment Canada indicates Greater Moncton is running about three degrees below normal for the month.

Snow mixed in with rain last night and 0.6 cm was recorded at the airport.

Today’s daytime high was 5.3°C and the forecast shows little change for tomorrow.

The Victoria Day long weekend is expected to bring some sunshine but temperatures will remain below seasonable.
