Louisiana braces for Barry

Barry TWN
Tropical Storm Barry continues churning in the northern Gulf of Mexico with sustained winds of more than 100 km/h.

The U.S. National Hurricane Center says Barry is expected to make landfall as a hurricane along the coast of Louisiana on Saturday morning.

The city of New Orleans is on alert for heavy rain (up to 500 mm) and flooding along with storm surges although no evacuations have yet been ordered.

This is the first tropical system to impact the United States in 2019.

After landfall, Barry is expected to weaken and head northward through the Mississippi Valley.

State of emergency lifted in Alberta

Days of severe weather including heavy rain, thunderstorms, hail, tornadoes and flooding led officials in western Alberta to declare a state of emergency.

However, Yellowhead County (west of Edmonton) dropped the declaration on Wednesday when floodwaters receded.

Many roads had to be closed or were made impassable after flooding and drivers were being asked to obey any barriers in place.

Residents were being warned about possible contamination of their drinking water.

Yellowhead County officials say at least 25 homes were directly impacted by floodwaters.

Freak hailstorm in western Mexico

Guadalajara was inundated with almost one metre of hail when a freak hailstorm moved through parts of Jalisco state on Sunday.

The governor posted photos on social media of buried vehicles, damaged homes and city workers alongside the Mexican Army shoveling the hail – even bulldozing it.

No reports of injuries or fatalities.

At 1,600 metres (5,000 feet) above sea level, meteorologists say high elevation played a role as one thunderstorm moved out and another one developed rapidly behind it bringing a huge quantity of small hailstones.

June 2019 – Mild and wet

The average monthly temperature for June in Greater Moncton was at least close to normal compared to a damp, cold May.

While daytime highs climbed to 20°C or higher on 20 days, significant heat was scarce and the thermometer didn’t even get close to 30°C.

Rainfall was heavier than normal – a measurable amount was recorded on 21 days – following a trend which began in early spring.

About three-quarters of the precipitation fell during the last ten days of the month.

Heavy rain hits Maritimes

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
  • Greenwood, NS  81
  • Kejumkujik NP, NS  72
  • Saint John, NB  61
  • Charlottetown, PEI  54
  • Summerside, PEI  53
  • Greater Moncton Airport, NB  52
  • Halifax Stanfield Airport, NS  41
  • Fredericton, NB  30
  • Yarmouth, NS  22

Hello summer!

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.

Thundersnow in B.C.!

A thunderstorm with snow is called thundersnow and it struck the British Columbia Interior just two days before the start of summer!

An unstable air mass bringing cold air from Alaska is to blame for the rare thundersnow which covered mountainous terrain in the Okanagan Valley with about 10 cm.

Snow fell above 1500 metres with a snow/rain mix down to 1100 metres and a chilly rain at sea level.

About 10 cm of snow was also expected in the Alberta Rockies from a similar system.

Severe weather in Manitoba, NW Ontario

tstorms
After a hot and windy day across southern Manitoba, severe thunderstorms developed late Friday afternoon with heavy rain, hail and lightning strikes causing at least one grass fire.

Daytime highs soared to 36.6°C in Winnipeg and 37.3°C in Carman which was the hot spot in Canada.

Temperatures dropped dramatically after the storms rolled through and damaging winds up to 100 km/h were reported in some areas along with nickel-sized hail.

The heat and thunderstorms moved east into northwestern Ontario with Kenora reaching 33.0°C yesterday and Armstrong climbing to 32.3°C today.

May 2019 – Miserable!

Irishtown Nature Park, Moncton, 20 May 2019 (Dearing)

May 2019 proved to be the coldest May since 1974 in the Maritimes with temperatures about two or three degrees below normal.

The month started out with some warmth in Greater Moncton but it turned colder near the middle with snow recorded as late as the 21st before a slight recovery at the end.

Overnight lows were cold with six nights either at or below freezing and most minimums were in the low single digits.

Cold, damp and cloudy weather stunted growth and forced farmers to delay planting because fields were saturated.

Only three days reached or exceeded 20°C and the thermometer came nowhere near 30°C at any time of the month.

MAY 2019 ALMANAC (at Greater Moncton Int’l Airport, 1981-2010)

Average HIGH  13.4°C

Average LOW  1.8°C

AVERAGE  7.6°C (about 2.4 degrees BELOW normal)

Extreme HIGH  22.1°C (25 May)

Extreme LOW  -2.7°C (02 May)

RAINFALL  105.8 mm (about 10 percent ABOVE normal)

SNOWFALL  0.8 cm (near normal)

The Year Without Spring

Snow in Rexton, 21 May 2019 (S. Hudson/Facebook)

It snowed overnight in Southeast New Brunswick.

About 0.6 cm of wet snow was recorded at the Greater Moncton Airport and even higher accumulations around the region.

In recent history, I can’t recall a snowfall this late in the month of May.

With meteorological summer arriving in 10 days and astronomical summer in barely a month, I’ve concluded that 2019 is the “Year Without Spring”.

The cold, damp weather has impacted farmers who are at least two weeks behind in planting crops due to saturated fields.

Sidewalk patios are eerily empty and winter parkas are still being worn by many.

A frost advisory has been posted for tonight and another one will likely be posted in two days as temperatures drop to near freezing again overnight.

Will the weather improve anytime soon?

A high of 20°C is forecast for Saturday but keep in mind we often hit 30°C before the beginning of June.
