Countryside near Victoria-by-the-Sea, PEI, 23 July 2018 (Dearing)
Another round of very warm temperatures and high humidity has enveloped almost all of the Maritimes with only New Brunswick’s Fundy coast exempt from an Environment Canada heat warning.
While actual daytime highs will approach 30 C, humidex values will range between 35 and 40 which can be dangerous for those at risk including young children, seniors and anyone with a chronic illness.
Forecasters say some relief may come on Thursday with some much needed rain but high humidity could persist until early next week.
Post-tropical storm Chris quickly moved across eastern Newfoundland late Thursday and early Friday with powerful winds, heavy rainfall and rough surf along the coast.
Gander recorded almost 80 mm of rain (almost a month’s worth), the southern Avalon Peninsula had high water swells of 6 to 8 metres above normal while Bonavista and Cape Pine recorded wind gusts above 100 km/h.
The Canadian Hurricane Centre issued its final bulletin for Chris early Friday as the storm sped off into the North Atlantic.

Chris is now a post-tropical storm with sustained winds of 110 km/h and is expected to make landfall in eastern Newfoundland near Cape St. Mary’s tonight.
The Canadian Hurricane Centre says strong winds combined with low pressure will create large waves and pounding surf giving the risk of coastal flooding along the southern Burin and Avalon Peninsulas.
Besides a wind warning, a rainfall warning has been issued with possible amounts of 50 mm or more and 20 mm an hour in the heaviest showers.
The remnants of Chris will drift away into the North Atlantic by early Friday morning.

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.
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.

When it snows in June it might as well be January which gives us a new month called Juneuary!

Gander set a new record with 2 cm of snow and Environment Canada said it has never snowed on 26 June before.
Thanks to a chilly rain, Greater Moncton reached a daytime high of only 11.0 C yesterday which was colder than the average overnight low of 12 C.
Average temperatures in Southeast New Brunswick have been running about three degrees below normal this month.

April was slightly colder than normal with chilly nights until mid-month and the last measurable snow fell on the 21st.
May had slightly above normal temperatures overall thanks to 14 days with daytime highs of 20 C or more but nights remained cold with single digit lows.
So far this June, the mean temperature is running three degrees below average with a hard frost on the 4th which was the coldest minimum since 16 April.

Spring has sputtered in New Brunswick – it was nowhere to be found in March, finally appeared in late April and although May has had a few warm days, the month is still running slightly below normal in Greater Moncton.
So what about summer?
In its seasonal forecast, the Weather Network believes a cool June should give way to more consistent warm weather during July and August.
A humid summer is expected which may result in warmer than normal temperatures at night – overnight lows average about 12 C.
While periods of dry weather are expected, heavy showers and thunderstorms should bring rain totals to near normal for the season.

Burgeo recorded a peak wind gust of 95 km/h as did Bonavista which also picked up 40 mm of rain.
Snowfall totals as of 3:30pm NDT:
- Gander 36 cm
