    *** VOLCANO NOT EXPECTED TO INFLUENCE NORTH AMERICAN WEATHER... The
    volcanic eruption in Iceland that is disrupting air traffic in Europe
    (and now Newfoundland) was likely not large enough to influence weather
    patterns and crop development in North America this summer, according
    to U.S.-based meteorologist Drew Lerner of World Weather Inc.

    While travellers moving through Europe continue to experience delays
    because of the volcanic ash, Lerner said the volcano that erupted under
    the Eyjafjallajoekull glacier was not actually a very large one and the
    potential to change global weather patterns is very low, "unless it
    continues to spew ash into the upper atmosphere for an extended
    period."

    Lerner said the volcanic ash would cause short-term visibility
    issues in Europe and may keep temperatures below their normals until
    the ash disperses. He said the ash was high enough to get into the jet
    stream, which means it will be carried around the world.

    Volcanic eruptions have been tied to shifts in global weather
    patterns in the past. In 1991, the eruption of Mount Pinatubo in the
    Philippines was tied to global reductions in average temperatures, but
    Lerner said the Iceland volcano was much smaller than that event.

    "It won't be any different than what occurred with Mount Redoubt in
    Alaska a year ago," said Lerner. He said that volcano did not have a
    large influence on weather patterns. "The whole reason we've had cooler
    weather has more to do with the solar cycle than particulate matter in
    the atmosphere," said Lerner. "It might have contributed to it, but I
    think it would be pretty minuscule."

    Overall, Lerner said the Iceland volcanic eruption could contribute
    to a cooler summer this year, but the actual correlation would be
    small. He noted that his forecasts were already predicting cooler
    conditions across the Northern Hemisphere this summer, regardless of
    the volcano, due to the solar cycle patterns.

      If it was predicted cooler before the eruption, the volcanic ash will certainly NOT make it any warmer. I'd guess TOO cool coming somewhere this summer or next winter. Watch the take on the markets.
