This summer has been hot, hot, hot! with temperatures significantly above normal...
But here's some advice...enjoy it now because things are expected to take a turn for the worse.

In this weeks "Your Green Life" Meteorologist Jeff Edmondson takes an early look at what is anticipated to be a snowy, cold winter.

We've had a lot of beach days this summer...nice weather for walking along the lake...but all good things must end and winter is not that far off.

Predicting a Northland winter can be tricky and one tool you need to use is look at sea surface temperature anomalies.
Several long range computer models are indicating a La Niña pattern for this winter which historically means cooler water along the equator in the Pacific Ocean.

"It's a normal occurrence, it occurs about every five to seven years," said Carol Christenson at the National Weather Service in Duluth, MN.

At the National Weather Service, they've been monitoring La Niña winters since 1948 and a few trends have emerged.

"Taking a look at the past La Niña's, we have found that the precipitation anomalies, meaning the greater precipitation amounts, occurred later in the winter season," says Carol.

What that means is that a typical La Nina pattern will bring more snow in the later part of the winter.
Temperatures on the other hand, have not shown a significant correlation to a La Niña pattern, so normal temperatures are expected this winter. The strength of a La Niña also plays an important role in the amount of snow we receive.

"We definitely see a La Niña developing but the strength is unknown right now, but we will be forecasting that in later months," says Carol.

If all of this talk of snow and cold has got you down, don't worry... there's still plenty of summer to go.
