    Hot Weather Basically a No-Show the Next Two Weeks

    7/31/2013, 10:15:32 AM

    Before I get to the weather, I just saw this newly released image from NASA Earth Observatory showing a dramatic view of Earth from under Saturn's rings courtesy of the Cassini spacecraft which was launched back in 1997. Makes us feel kind of small in the big picture, doesn't it?


    The overall weather pattern across North America over the next 7 to 14 days will likely keep most of the heat confined to the South Central and Southwest states, while temperatures average cooler than normal from the Prairies through Quebec and down into the Midwest and Northeast states.

    However, the very warm weather pattern will likely continue across northwest Canada for at least the next 10 days.

    There are some indications that warm and more humid conditions may return to eastern Canada after Aug. 15.

    A storm will form along a front Friday afternoon and evening and will likely bring a period of steady rain to the Maritimes. Total rainfall could approach 25-30 mm in some areas.

    A dome of high pressure will settle across the Prairies early Saturday. The combination of the chilly, dry air and light winds could send temperatures into the 1-3 C range across southern parts of Saskatchewan and Manitoba early Saturday morning.

    An upper-level storm system moving into the Pacific Northwest of the U.S. may track far enough to the north to bring a significant rainfall to extreme southwestern Alberta (Waterton Lakes area) Thursday night and Friday this week.

    Current global sea surface temperature anomalies

    The image below shows the most recent weekly sea surface temperature anomalies for the world. As you can see, unusually warm anomalies dominated across the northern latitudes.


    Farther south, the El Nino Southern Oscillation (ENSO) remains in a near neutral state (-0.3) and is expected to do so through the fall. When the numbers are above +0.5 for three consecutive three-month periods it is considered an El Nino (warmer-than-normal sea surface temperatures across the equatorial Pacific). The opposite is true for La Nina.
