Brisk start to September

Astronomical summer may be officially over but no one expects to see snow at the start of September after a cold front pushed Arctic air southward across Eastern Canada.

With temperatures near freezing, several centimetres of snow fell in northeastern Quebec and Labrador West overnight and drivers say the roads quickly became slushy and slippery.

Greater Moncton felt autumn-like with strong gusty winds under a mostly cloudy sky and temperatures struggled to reach the high teens Celsius.

Environment Canada issued a frost advisory late Sunday afternoon for Greater Moncton and Southeast New Brunswick – almost a month before the average date of the first fall frost.

Clearing skies and light winds with temperatures falling into the lower single digits could have resulted in scattered frost.

However, the frost advisory ended early this morning when the threat was no longer expected.

The low at the Greater Moncton International Airport was 7.2 C which is several degrees away from any threat of frost.

However, the morning low in Edmundston was a chilly 1.1 C.

Late July is typically the warmest period of summer in Greater Moncton but a recent cool down has brought September-like days and a record overnight low. 

On 23 July, the temperature fell to 6.9 C at the Greater Moncton International Airport which broke a record low of 7.2 C from 1962. 

A frost advisory was posted in northwest New Brunswick with a chilly low of 2.4 C in Edmundston. 

The short term forecast calls for more seasonal highs in the mid-20’s C and lows near 13 C. 

Cool, unsettled start to June

Weather conditions have been cool and unsettled in the Maritimes over the past several days.

While driving in Nova Scotia on Friday, I encountered everything from clouds and heavy downpours to a clearing sky with bright sunshine to clouds and rain again.

On the way home to New Brunswick on Saturday, I encountered similar conditions.

In Greater Moncton today, the thermometer climbed to a daytime high of only 10.6 C under a dreary sky which is about 10 degrees below normal for early June.

Forecasters say warmer, more seasonal temperatures will return by Wednesday but not before a risk of frost in Southeast New Brunswick by early Tuesday.

July cold snap ends

Some claimed it was time to haul out the parkas again after five straight days with daytime highs failing to reach 20 C in Greater Moncton.

Keep in mind the average early July high is 25 C and recent daily maximums were barely climbing to 15 C.

Data shows this has been the coolest stretch in July in many years.

But grey skies are finally clearing and Environment Canada is forecasting highs at or slightly above normal over the next few days.

Cooler than normal in N.B.

Greater Moncton typically reaches a daytime high of 25 C in early July but while it was 28 C yesterday, it was only 19 C today and perhaps slightly cooler tomorrow.

The below normal conditions – coming after several weeks of warm weather – are due to a chilly north wind and two low pressure systems merging over Atlantic Canada.

On a positive note, some needed rain is on the way after a recent dry spell in Southeastern New Brunswick.

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.

May 2016 – Full of surprises

Greater Moncton was actually warmer than normal in May according to Environment Canada but somehow it seemed cooler than average.

Overnight lows were quite cold throughout the month with five nights either at or below freezing and just three nights at or higher than 10 C.

Daytime highs varied widely with six days failing to reach 10 C and eleven days climbing to at least 20 C or more.

Rainfall was below normal with snow flurries spotted on 09 May and measurable snow in western New Brunswick as late as 16 May.

Spring sputtered in Southeast New Brunswick during April with cold overnight lows and daytime highs were all over the chart.

Precipitation was below normal with little snow in Greater Moncton and rainfall was about 20 percent below average.

Although the thermometer climbed into the 20’s on a couple days, lows were so chilly during the last week that records were challenged on several nights.
