Barry has been downgraded to a tropical depression after making landfall west of New Orleans on Saturday as a Category 1 hurricane.
Although Barry did not bring devastating flooding as some forecasters had originally thought similar to Hurricane Katrina in 2005, parts of Louisiana did receive more than 400 mm of rain which swamped the Mississippi River delta.
Emergency responders rescued at least 90 residents but there were no reports of fatalities.
Remnants of Barry have been moving northward with heavy rain across the American South up to the Midwest.
An approaching low pressure system could bring the first significant snow of the season to much of New Brunswick this weekend.
Environment Canada has issued a snowfall warning with at least 15 cm and Accuweather is suggesting 8-15 cm could fall in Greater Moncton by Sunday.
Strong northeasterly winds are also in the forecast which may cause higher than normal water levels along the coastlines.
Nova Scotia is expected to receive mostly rain and there is some mixing of rain and snow possible for Southeast New Brunswick.
The same system also brought rare snow to northern Mexico and across the American South.

A low pressure system south of the Great Lakes is tracking eastward and will impact New Brunswick overnight.
Some areas of the province such as Saint John and Fredericton are expecting freezing rain and Environment Canada has posted warnings.
Greater Moncton will receive mostly snow with less than 6 cm expected which falls below warning criteria.
This system is connected to an extensive weather front which has brought torrential rain to the American South – up to 300 mm in the Lower Mississippi River Valley – causing flooding, several deaths and thousands being evacuated from their homes.

More than 30 people have been killed by a series of tornadoes across the American South since Sunday.
The states of Arkansas and Mississippi have been hardest hit with hundreds injured, neighborhoods flattened, homes reduced to splinters and trees snapped like twigs.
Tornadoes have also knocked out power to tens of thousands across several states.
Forecasters were calling for more severe conditions today especially near the U.S. Gulf Coast.

All modes of travel were halted over the American South yesterday from Texas to North Carolina thanks to a winter storm that dumped freezing rain and snow on the region.
Although most areas received less than 10 cm of snow, the region is not used to wintry weather and some cities don’t even have snow plows or salt trucks.
At least five states declared emergencies when motorists were left stranded in their vehicles, students were forced to stay in schools overnight and many others sought shelter in churches and even grocery stores.
Icy highways led to hundreds of collisions, many involving tractor trailers which jack-knifed and blocked traffic.
The same system is impacting the Maritimes today with less than 5 cm of snow expected in New Brunswick and higher amounts near the Atlantic coast of Nova Scotia.

For many in Southern Ontario, this wintry wallop was the first major snowstorm of the season dumping about 15 cm of snow on Windsor, Toronto and Hamilton with 20 cm in Ottawa and 30 cm in Kingston.
Montreal could receive as much as 40 cm of snow while Quebec City can expect about 20 cm.
The storm actually originated in the American South dropping rare post-Christmas snow on cities like Dallas, Texas and Little Rock, Arkansas.
After hammering the U.S. Northeast with snow and rain, the storm is now moving into New Brunswick and Nova Scotia with snow, strong gusty winds and rain along the Atlantic coast.

What a beautiful time of year in Greater Moncton!
Trees are sprouting leaves, flowers are in full bloom and the aroma of freshly cut grass is everywhere.
During a walk yesterday, I captured several magnolia trees blooming in Riverfront Park.
A horticulturist friend of mine mentioned the trees, which are native to the American South, have suffered some damage in recent days given that overnight lows have dropped below freezing.

Environment Canada says March in New Brunswick has never been warmer.
Temperatures have soared into the mid-20’s Celsius this week smashing records that date back to the 1870’s.
Meteorologist Claude Cote says the heat is coming from the American South.
“Over the western part of the country we have this trough of low pressure, so there’s lots of southerly circulation east of the low pressure which is why it’s bringing hot, dry air from the southern American states,” notes Cote.
More record highs have already fallen today throughout New Brunswick.
But Cote adds a big change is on the way with a cold front moving in tonight and more seasonal temperatures tomorrow.
Spring is definitely in the air in New Brunswick today.
Environment Canada meteorologist Linda Libby says a warm air mass over the region could push temperatures into record territory today.
“We’re looking at daytime highs anywhere from the high single digits up to the mid-teens Celsius in New Brunswick today depending on your location,” Libby notes.
The warm air mass, which originated in the American South, broke records in Ontario and Quebec yesterday.
The record high in Moncton for this date is 13.5 degrees from 1995 and in Saint John the record is 9.4 degrees from 2010.

Snow falls in Memphis, TN, USA, 28 Nov 2011 (AP)
Snow does fall in the American South but rarely in November as it did yesterday and today.
Snow fell in cities such as Nashville, Memphis and Jackson, Tennessee (where as much as 10 cm was reported) which seldom see more than a few flakes before December.
U.S. weather officials say the last time Nashville saw more than two centimetres of snow in November was in 1966.
Tupelo, Mississippi has only seen three days with measurable snowfall in November since 1930.
Schools closed in some areas after the snow created icy bridges and overpasses.
