    A Look at Water Temperatures and Northern Snow Cover

    10/09/2013, 4:45:11 PM

    The EC map below shows the up to date surface water temperature anomalies for North America and also the current snow cover.


    In terms of surface water temperatures, we can see a large pocket of cooler (blue) than normal water over the northeast Pacific, while the waters off Atlantic Canada continue to be warmer relative to normal, which I expect to be the case through the upcoming winter.

    Also, note the warm (red/orange) anomalies for the Great Lakes and Lake Winnipeg.

    The combination of a cooler summer and recent meltwater has sent water temperatures slightly below normal from Hudson Bay up through the Baffin Island region.


    The grey areas show current snow cover, which you can see extending down through parts of the Yukon Territory and over the Canadian Rockies.

    By the way, snow cover in northern Canada is currently averaging below-normal (red). See the snow anomaly map below from the Rutgers Global Snow Lab......



    Note: We will be closely monitoring the snow cover anomalies over parts of north-central/northwestern Asia during the rest of this month. Some studies show a link between a higher than normal snow cover growth over this region during October and second-half of the winter high-latitude blocking over the Canadian side of the Arctic, which can produce severe winter conditions farther south into southern Canada and the eastern half of U.S.


    We will be officially releasing the 2013/14 AccuWeather Canada winter outlook on Wednesday, October 16th, though I will likely blog about parts of the outlook on Monday and Tuesday.
