A double rainbow after brief rain shower over Moncton, 04 July 2018 (Dearing)
Temperatures across Eastern Canada from Ontario to the Maritimes continued to soar into the 30s C with humidex values above 40.
Authorities in Quebec say at least 18 people have died, all over age 50, as a warm, humid air mass lingered over the province.
Record highs have been recorded in New Brunswick with a new maximum of 31.6 C at the Greater Moncton International Airport on Tuesday (beating 31.0 C from 1984) and 33.4 C today (beating 31.4 C from 1983).
The hotspot in the province was 34.1 C at St. Stephen.

Record highs could be broken in Greater Moncton over the next couple of days if forecast highs in the low to mid 30s C are reached on Tuesday and Wednesday.
Environment Canada has issued a rare heat warning for New Brunswick, mainland Nova Scotia and Prince Edward Island with cooler conditions along the coast.
A warm, humid airmass is expected to push humidex values about 40 during the day and barely falling below 18 C at night – dangerous levels for those susceptible to heat.
Forecasters believe warm, humid weather will persist until later this week when a cold front brings temperatures closer to normal for the weekend.
Ogilvie Brook, Irishtown Nature Park, 24 June 2018 (Dearing)
Greater Moncton has endured the coolest June in recent memory and while daytime highs were close to normal – with a few exceptions – overnight lows were cold, even frosty at times during the first half of the month.
A hard frost on 04 June with a record breaking low of -3.2 C was devastating for agriculture across New Brunswick especially in the Southeast.
Farmers suffered major damage – in some cases 50 to 80 percent losses – to crops such as grapes, strawberries and blueberries.
Oddly enough, the temperature had not been that low in all of May and not since 16 April had it been at least that cold.
Rainfall was about 60 percent above normal and was confined to a handful of major rain events with nine days being completely dry.

We are now several weeks into the growing season and temperatures are dropping to dangerously cold lows.
Farmers are concerned about damage to crops after a cool air mass and clear skies led to a frigid low of -4 C in parts of New Brunswick and Nova Scotia overnight.
Greater Moncton dropped to -3.2 C early today which broke the old record of -2.2 C from 1903 and records go back to 1881.
The following new record lows were set on 04 June:
- Kouchibouguac National Park, NB -3.8 C (records since 1924)
- Grand Manan, NB -2.2 C (records since 1883)
- Port Hawkesbury, NS -2.6 C (records since 1875)
- Ingonish, NS -2.2 C (records since 1950)
- Summerside, PEI -1.9 C (records since 1898)
- Charlottetown, PEI -1.0 C (records since 1872)
Thanks to high pressure and a jet stream surging north, New Brunswick will feel the heat over the next two days.
Greater Moncton is expecting a high of 30 C today and 31 C tomorrow with humidex values between 30 and 36.
Environment Canada says the warmest conditions will be from mid-afternoon to early evening and precautions should be taken in extreme heat.
The passing of a cold front this weekend will bring temperatures closer to normal.
Flooding in Grand Forks, BC, 11 May 2018 (Regional District of Kootenay Boundary)
A combination of heavy rain, warm temperatures and rapid snowmelt from the mountains has created major flooding in Interior British Columbia.
About 4,000 residents have been evacuated from their homes mainly in the Regional District of Kootenay Boundary.
At the confluence of two rivers – the Granby and the Kettle – the city of Grand Forks has been hardest hit where firefighters have rescued dozens by boat.
The province has issued evacuation orders or alerts in six other regional districts and eight First Nations.
Officials say this spring’s flooding is worse than the devastating floods of 1948.
Dandelions growing in NE Moncton, 02 May 2018 (Dearing)
Dandelions have made their return to Southeast New Brunswick a little later than usual thanks to a cold spring.
The yellow plants or weeds were spotted today when the temperature climbed to 24.5 C in Greater Moncton – the warmest high so far this year.
The hotspot in New Brunswick was St. Stephen at 29 C and Fredericton was not far behind at 28 C.
But a cold front is pushing through the province which will bring rain and dramatically lower temperatures overnight with single digit highs expected tomorrow.
Given the recent stretch of below seasonal temperatures in Southeast New Brunswick, I wasn’t optimistic we would reach 20 C anytime soon.
But yesterday the thermometer climbed to 21.2 C in Greater Moncton marking the first time to reach and surpass that threshold in 2018.
Over the last five years, we have reached 20 C over a two week period from mid-April to early May.

Light dusting of snow in NE Moncton, 20 April 2018 (Dearing)
Could this finally be the last snow of the season?
About 5 cm of snow was recorded at the Greater Moncton International Airport yesterday although it only stuck to grassy surfaces, vehicles and rooftops and didn’t settle on pavement.
Another dusting of snow fell this morning in Greater Moncton but again didn’t stick to paved surfaces.
Coincidentally, several centimetres of snow fell on 20 April last year too.
Forecasters say a warming trend is coming with temperatures finally getting into the double digits this week.

The snow has finally vanished from the front lawn of my home in northeast Moncton!
The top photo shows a lot of snow on 09 April while the last of it melted by 19 April in the bottom photo.
Despite below normal temperatures which struggled to reach 10 C, the snow disappeared in just 10 days.
