Heat wave abruptly ends in N.B.

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The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

Excessive heat warnings have been posted in parts of California, Nevada, Utah, Arizona and New Mexico where record highs have been broken.

Las Vegas tied its record today of 47 C and Phoenix came close to its all-time high at 48 C.

Many flights have been delayed or cancelled since smaller jets can’t operate properly in dangerously hot conditions.

Temperatures have soared to 53 C in Death Valley, California which climbed to 56.7 C on 10 July 1913 – the hottest ever in North America.

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.

The heat is on in New Brunswick!

It’s now mid-August and I was starting to give up hope we would have a heat wave this summer in New Brunswick.

But low and behold, a Bermuda High and a favourable jet stream pushed the temperature in Greater Moncton to 31.8 Celsius today – the warmest so far in 2015.

The hotspots in the province today were at Bathurst, Fredericton and Kouchibouguac which all reached 33 C.

The heat continues for the next few days in the region.

Environment Canada officially defines a heat wave as three consecutive days with daytime highs of 32 C or higher.

Is a heat wave finally coming to New Brunswick?

The summer of 2015 so far in Southeast New Brunswick could be called pleasant with periods of rain and cloud thrown in for good measure.

But something has been missing this year – where’s the heat?

The last time the thermometer topped 30 C in Greater Moncton was back in the late spring when it topped that mark on 27 May.

A couple of times we have come close at 29 C but a heat wave of any sort has been noticeably absent.

Environment Canada is calling for a warming trend this weekend which could culminate in a high of 31 C on Monday.

Remember the March 2012 heat wave?

On this date in 2012, the thermometer soared to 26.1 C in Greater Moncton – the highest temperature ever in March with records dating back to 1871.

The previous two days were also unseasonably warm at 25.3 C and 21.0 C.

Those three days shattered the previous March record high of 18.9 C from 1945.

Fast forward to today, with an expected high of 4 C and a chance of light snow tonight.

Greater Moncton had more rain than usual during July with 17 days recording at least a trace amount but other communities such as Fredericton and St. Stephen were much wetter.

When the rain came down it poured with major events on July 23 and 26 with about 40 mm recorded each day.

Daytime highs were quite warm with an unofficial heat wave from July 4-7 and eight days reaching 30°C or higher – the normal for Moncton is about three.

A warm air mass is bringing record-breaking heat to much of New Brunswick with the entire province under a humidex advisory with values reaching 40.

In Greater Moncton a new record of 32.2°C was set yesterday eclipsing the old record from 1942 while today it was 34.3°C breaking a record from 1952.

The provincial hotspot was Kouchibouguac yesterday at a sizzling 35.2°C also setting a new record while today it was even warmer at 37.3°C!

Environment Canada says temperatures will be a bit cooler tomorrow with a high of 28°C expected in Greater Moncton.

In its annual list, Environment Canada has chosen the top weather stories of the year – from super storms to super heat, and from immense flooding to immense fires.

1. BIG HEAT
Temperatures were above normal across Canada during winter, spring and summer from coast to coast to coast.

2. ACTIVE HURRICANE SEASON
By the end of the Atlantic hurricane season, 19 named storms were recorded with Chris, Leslie, Rafael and Sandy impacting Canada.

3. BRITISH COLUMBIA FLOODING
High levels of early spring flooding in British Columbia caused washouts, and slides, evacuations and fatalities.

4. MARCH MILDNESS
The March heat wave was off the scale in every way: intense, huge and long-lasting. In Moncton, a new record monthly high of 26 C was recorded.

5. WILD PRAIRIE SUMMER
Summer on the Prairies started out with short-lived cool temperatures and ended as one of the top ten warmest on record.

6. BIG MELT
The year will go down as one of extraordinary change across the Arctic Ocean, with sea ice becoming dramatically thinner, weaker and younger and melting more easily.

7. HIGH AND DRY IN THE EAST
Higher than normal temperatures and a lack of rainfall in Eastern Canada meant a great summer for most outdoor enthusiasts but trouble for some crops and water systems.

8. URBAN FLOODING
Thunder Bay experienced record breaking flooding in May while Montreal and Toronto also found themselves with expensive floods weeks later.

9. CALGARY HAILSTORM
A monstrous hailstorm pelted Calgary with hailstones larger than golf balls on August 12th and in a matter of 10 minutes, pounding hail dimpled vehicles and riddled house siding with millions of dents.

10. SAINT JOHN RIVER ICE-JAM FLOODING
The first days of spring were marked by a mandatory evacuation for residents of Perth-Andover and Tobique First Nation when the Saint John River and several tributaries spilled onto nearby fields and roads.

Beach weather in March!

Parlee Beach, NB, 22 March 2012

It seems hard to believe, but dozens of sun seekers hit Parlee Beach yesterday (22 March) and some even jumped in the water!

Keep in mind that patches of ice are still floating in the Northumberland Strait!

But with the temperature peaking near 26 C, it was hard to resist the beach during this week’s record-breaking March heat wave in New Brunswick.

After a cold front moved into the region overnight, temperatures have returned to more seasonal values but Moncton was still above normal today with a high of 10.0 C.
