The Omega Block returns

img000006What is going to be beinging our beautiful weather this coming week? The Omega Block! Simply put, an omega block is when we observe a prolonged pattern of Trough-Ridge-Trough in the upper levels. If you use your imagination, this pattern can sometimes resemble the Greek letter “omega”. Since this is a blocking pattern and will not be going anywhere too fast, we will be enjoying broad northwest flow which will pour in comfortable and stable air. Expect mostly clear skies through at least Thursday with lower humidities and temperatures in the lower 80’s.

    Hi Aaron,

    Do you think we’ll see any air quality alerts? I remember how stagnant the air got last year during these types of patterns.

    At this point, it looks to last through Saturday!

    And that is of some concern. Usually those come with hot airmasses as well. We will look at that possibility and analyze how strong upper level winds are toward the end of the week

    Oh good. I’m ready for this stormy pattern to be done for a while. And my lawn needs to stop growing so fast too!

    If the first two weeks get canceled, they are looking at losing four home games in what is already a road-heavy beginning of the season.In total, the Bulls only have five home games during November, and if a deal would be reached those games would most likely not be made up. Fans would lose the chance to see the Thunder, Kings, Clippers and Hawks with the fifth and final home game against the Spurs on Nov. 30.
