    Cool Air to Dominate Into Early May

    4/25/2014, 10:35:02 AM

    Latest pattern signals and model data continue to support a cool weather pattern across large portions of Canada and the U.S. into the first part of May. Beyond that, there is higher uncertainty than normal as to what type of jet stream pattern will dominate.

    In the short term, a blocky pattern will form across the north next week, and this will cause a storm moving out of the western U.S. to stall near the Ohio Valley or Great Lakes for a few days next week. The result of this will be a cool, wet pattern for eastern Canada and the eastern half of the U.S.

    In fact, southern Ontario could see at least some rain everyday between Tuesday and Friday next week. At least it's not on the weekend for a change!
