Winter vs. spring – the battle begins…

Spring is officially here but anyone living in New Brunswick knows that now is often when the battle lines are drawn.

Cold Arctic air can linger and along with an almost ice-covered Gulf of St. Lawrence creates a cooling affect which repeatedly fights it out with warm, moist air from the Gulf of Mexico.

Environment Canada has issued a snowfall warning for Greater Moncton as a low pressure system intensifies tonight over the Maritimes with as much as 15 cm expected by late Sunday.

The Canadian Ice Service map shows ice is breaking up in the Gulf of St. Lawrence around Anticosti Island, Lakes Ontario and Michigan are nearly ice-free but the Labrador coast and Hudson Bay are still solidly frozen.

Meteorological summer begins

The first day of June marks the beginning of meteorological summer in the Northern Hemisphere.

In New Brunswick, we are hoping for much better weather than the last three calendar months which have been cold and relatively wet.

Forecasters say part of the blame may come from colder waters including the Great Lakes which still have almost two percent ice cover on Lake Superior.

This is the latest date in recent memory – since 2003 – for ice on the lake which is mainly hugging the southern coast bordering the states of Michigan and Wisconsin.
