    People who make long range weather forecasts say this summer’s heat wave is not that unusual. Other areas of the country have seen much higher temperatures at longer periods of time. But a combination of climate events could have severe long range consequences. John Cadiz Klemack reports from Malibu for the NBC4 News at 6pm on Wednesday, August 15, 2012.

    A two-week summer scorcher is expected to last about one more week as above-normal temperatures persist in valley and mountain areas of Southern California.

    A stalled high-pressure ridge over the West Coast is behind the extended bout of triple-digit temperatures and high humidity levels.

    “This weather pattern is the longest lasting, most intense we’ve had in the last decade,”Jet Propulsion Laboratory oceanographer and climatologist Bill Patzert told NBC4.

    The hottest heat wave of the decade was in the summer of 2006, when temperatures were routingly breaking the 105-degree mark, according to meteorologust Mark Jackson of the National Weather Service's office in Oxnard.

    Here's a look at today's weather forecast.

    "We're approaching the time of the year that our fire danger will be at a critical level," Jackson said, noting the persistent high-pressure system.

    Hot conditions are expected through early next week as temperatures remain above normal.

    Triple-digit heat continued Wednesday in some areas, but a more expansive marine layer over the West Coast will tame the scorching heat until the humidity returns Friday.

    “We got a nice onshore breeze picking up this morning and that’s going to carry to allow for some cooler temperature readings this afternoon,” said NBC4 forecaster Elita Loresca.

    In the mountain areas, there is a slight chance of a storm.
