Autumn 2017 – Abnormally dry (YELLOW), Moderate drought (TAN), courtesy Agriculture Canada
Central New Brunswick is experiencing a moderate drought while much of the rest of the province is abnormally dry except for the Acadian Peninsula according to Agriculture Canada.
Forecasters say two weather systems could bring as much as 100 mm of rain on Thursday and Friday which is welcome relief for a prolonged dry period which began in early summer.
Environment Canada has issued rainfall warnings for western and southern New Brunswick but the Southeast is expecting less than 40 mm.
Meantime, more record highs were broken across the Maritimes today as southerly air continued to push temperatures well into the 20’s C.

September turned out to be a continuation of summer in Southeast New Brunswick right up until month end.
Daytime highs in Greater Moncton climbed above 25 C on ten days and a monthly maximum of 31.1 C turned out to be the warmest of 2017 set in early fall (26 Sept).
Although hurricanes never directly affected the province, meteorologists say much of the warmth last month came from tropical air pushed northward from these storms.
Rainfall was exactly normal but almost all of the precipitation fell during a single rain event spread over two days (6-7 Sept).

This may have been the first weekend of autumn in Southeast New Brunswick but it felt more like the first weekend of summer instead.
Greater Moncton climbed to 27.7 C yesterday (23 September) while today (24 September) it hit 27.9 C and the normal high for late September is 17 C.
High pressure and a northerly jet stream has pushed heat across Eastern Canada with highs in the low 30s C in many parts of Ontario and Southern Quebec.
A heat warning was in place as Toronto Pearson Airport reached a record-breaking 33.1 C yesterday and 33.6 C today.

If you were looking for great summer weather in the province, Environment Canada says Greater Moncton and Southeast New Brunswick was the place to find it this year.
The average temperature for meteorological summer – June, July and August – was 18.1 C which is 0.7 degrees above normal.
The weather office says humidity was often low, overnight lows were comfortable but 8 days hit 30 C or higher compared to a typical 4 to 5.
The downside was a lack of precipitation with 155 mm of rain recorded which is 40 percent less than the summer average of 268 mm.

The dry summer in Southeast New Brunswick continued in August with a dangerous forest fire hazard and little precipitation to soak the parched ground.
A dry trend which began in late June continued during the month with less than 50 mm of rain falling in Greater Moncton.
Temperatures were above normal with daytime highs consistently in the high 20’s Celsius but a string of single digit overnight lows during the final week brought down the overall monthly average.

Flooding in Buffalo Bayou Park, Houston, TX, USA, 27 Aug 2017 (Twitter)
Harvey may have been downgraded to a tropical storm as it moved inland over Texas but the U.S. National Weather Service stated “this event is unprecedented and all impacts are unknown and beyond anything experienced.”
Forecasters say the Houston metropolitan area could receive more than 1000 mm of rain from the storm over the next few days which has claimed at least five lives.
By early today, more than 600 mm had fallen in America’s fourth largest city overwhelming lakes and rivers forcing thousands of residents scrambling into boats or onto rooftops to safety.
Tornado warnings have been lifted but a flash flood warning remains in place for much of southeastern Texas.

For whatever reason, summer seems to go by faster than the other seasons and here we are already at the midway point of July.
After 16 days, Greater Moncton has been having a decent month with an average temperature of 19.3 C which is 0.5 degrees above normal.
Daytime highs have been warm but not hot with a peak of 29.4 C on 16 July while overnight lows have been mild except for a chilly low of 8.9 C on 05 July.
The only concern is a lack of rainfall.
The tally is 19.8 mm so far – less than a quarter of the monthly total – but keep in mind we are entering what is traditionally the driest period of the year in Southeast New Brunswick.

Active wildfires burning in BC, 13 July 2017 (BC Wildfire Service/Google)
More than 300 firefighters from across Canada including New Brunswick are now in British Columbia to relieve those already on the ground battling over 180 wildfires.
Some progress has been made thanks to recent cooler weather but 14,000 residents have been evacuated and thousands more are on alert to leave their homes at short notice.
Forecasters say gusty winds expected this weekend could fan the flames even further and the heat is also expected to return.
The economy of the B.C. Interior is taking a hit this summer with many campgrounds and provincial parks forced to close due to the wildfires and related road closures.

The Weather Network has released its summer 2017 forecast covering June, July and August.
A changeable summer is expected across Atlantic Canada with extended periods of above seasonal and below seasonal weather.
The southern Maritimes which includes Greater Moncton and Southeast New Brunswick and possibly into southern Newfoundland have the best chance of seeing temperatures tip to the warm side of normal.
Meanwhile, cooler than normal temperatures are expected to be more persistent across eastern Labrador and northern Newfoundland.
Near normal rainfall is expected this summer except for western and northern New Brunswick.
There is the potential for a couple of systems to tap into subtropical or tropical moisture and bring above normal rainfall to parts of the region.
