    Another September Preview

    August 14, 2014; 7:05 AM ET

    Thursday morning

    The storm that brought extreme rainfall to Detroit, then Baltimore, then Islip, New York, and Portland, Maine, is now moving northward through eastern Canada. In Monday's report I wrote, "As with other rain-producing systems this summer, this one is likely to include narrow bands of excessive rain capable of causing street flooding in a matter of minutes."

    Of course, even if we know this well on advance, it is an entirely different story trying to pinpoint the exact wheres and whens until we are much closer to when it actually occurs. This is an important issue: how to get the message across that you may die or be injured in a particular area while telling folks elsewhere there is much less concern. Another storm system next week could move east from the Ohio Valley or southern Great Lakes to raise the same issues and questions. Here is my forecast video:

    Looking beyond next week, we see signs of something that has been missing in the Great Lakes and Northeast just about all summer: hot weather. That may change. Here is a computer model prediction of the upper air flow on Sunday, Aug. 24. Note how the flow appears to run from Arizona all the way to north of New England.
