The next heat wave across Eastern Canada could be the warmest period yet this summer with daytime highs in the low 30’s C and humidex values near 40.
Southern Ontario and Southern Quebec have been blanketed with heat warnings from Environment Canada with hot, humid days and warm nights expected this weekend.
Temperatures in the Maritimes for Saturday and Sunday could reach 30 C but a cold front will bring cooler and drier air by Monday.
A mini heat wave already brought highs of 29 C and 30 C earlier this week in Greater Moncton.

After a cool and wet start to summer, a blast of heat is heading to the Maritime Provinces over the next few days.
Environment Canada has issued heat warnings for most of New Brunswick – excluding the Fundy coast – and western Nova Scotia while other areas under a special weather statement.
A warm, humid air mass is moving into the region today raising daytime temperatures to 30°C or more.
Humidex values near 40 are expected and overnight lows may not fall below 18°C providing little relief from the heat.
Near normal values will return late Saturday as a cold front arrives.
Heat warnings are also in place for parts of Ontario and Quebec where it climbed into the low 30s yesterday.
The last couple of nights have been chilly across New Brunswick with overnight lows in the low single digits.
While Greater Moncton fell to 5.5°C which was a few degrees away from the record, the same minimum in Bouctouche was cold enough to set a new low.
Edmundston dipped to a nippy 1.1°C which tied its record as did Grand Manan when it dropped to 3.8°C.
Over the last six years in Greater Moncton, the chart above shows temperatures have not fallen to the freezing point or lower after early June.

A slow moving low pressure system crossed the Maritime Provinces on Friday bringing heavy rain to the region.
Environment Canada had posted rainfall warnings for many areas with 40 to 60 mm in southern New Brunswick and Prince Edward Island and up to 100 mm in northern Nova Scotia.
Here are some rainfall totals (in mm):
- Parrsboro, NS 123

The summer solstice officially arrived in New Brunswick at 12:54 pm ADT and it was certainly welcome after a relentlessly cold spring.
Greater Moncton enjoyed 15 hours and 46 minutes of daylight today but unfortunately the sun didn’t make an appearance due to lots of clouds and heavy rain.
The sun is directly over the Tropic of Cancer and it will now begin moving south toward the equator which means days will get shorter – ever so slowly starting tomorrow.
As for summer weather predictions, The Weather Network is suggesting warmer than normal temperatures in July and into August with near normal precipitation.
Environment Canada is calling for near normal temperatures and near to slightly above normal precipitation.

The Victoria Day long weekend marks the unofficial start of the summer season in Canada when opening up the cottage or camping are on the agenda.
However, many residents are still wearing heavy, winter jackets and gloves as daytime highs struggle to reach 10°C in Southeast New Brunswick.
The normal maximum in Greater Moncton is about 18°C but the long range forecast shows it won’t be that warm for another six days!
Environment Canada has issued a frost advisory for all of New Brunswick and most of mainland Nova Scotia as the overnight low drops to near freezing.
On the upside, the advisory means the growing season is now officially underway but on the downside, it’s not warm enough to plant anything.
Flooding in Fredericton, 24 Apr 2019 (GNB/Yerxa)
The New Brunswick Emergency Measures Organization says water levels continue to recede and are now below flood stage along most of the St. John River system.
Several roads remain closed and drivers are told to respect any barricades.
The provincial government has launched a disaster assistance program to help residents, businesses and municipalities deal with property damage from flooding.
Health officials are warning about harvesting wild, edible plants like fiddleheads near flooded waterways which may have been exposed to contaminants.
May is here which means it won’t be long before Jack Frost visits Atlantic Canada for the last time this spring.
Mid to late May is typically when the last frost arrives in Greater Moncton, early in the month for Halifax and late April for Yarmouth.
Early to mid June dates are normal for most of Newfoundland and Labrador.
Last year in New Brunswick and Nova Scotia, frost appeared as late as early June which proved disastrous for grape, blueberry and strawberry farmers.

Spring can be the most disappointing season of the year in New Brunswick and April 2019 was no exception with cloudy, cool and often wet conditions.
Surprisingly, Greater Moncton was close to normal in temperature but double the average amount of rain fell along with slightly more snow than usual.
Melting snow and heavy precipitation led to more disastrous flooding along the St. John River – almost as bad as last year’s historic water levels.
Only one day was fully below freezing and while nights weren’t that cold, daytime highs often struggled to reach the double digits.
