Fall Weather Fans Rejoice!

Fall weather fans will have cause to delight in outdoor conditions right into the weekend.

A series of large mid-level lows to our east will circulate cool Canadian air southward. A warmer pattern under the upper high should remain to our west. The interaction between the high and the low provides a very dry storm track; surface high pressure has played its part by pushing all significant moisture deep into the southern and eastern Gulf.

With northerly surface flow expected to keep Gulf moisture far removed until next week, there’s little reason to expect any rain. In fact, skies should be mostly clear with cool nights and warm days. The only factor that presents a bit of uncertainty is the large upper low (blue arrows) to our east.

If this were to move further west than expected, it could make things more on the cloudy side or even bring a little light rain. However, the odds of this are low based on the steering pattern. Sometimes a strong upper system can overcome dry lower layer of air and utilize moisture higher in the air to “squeeze out” some rain, but again this possibility appears very small given the evolving scenario.

So my confidence is high that “open your windows” weather will hang around at least through the weekend.

Take Care,

Steve LaNore

    Fonzie, I agree with the NOAA fall outlook as this is typical for a moderate to strong LaNina event. But, that doesn't mean we won't have a cold spell or two. In fact, strong La Ninas can favor short intense cold spells as in Dec. 1989...so we'll just have to hide and watch. Take Care, Steve

    Yes, yes. We all can use a little Weather 101. Great questions CJ! BTW, Steve I saw the NOAA is forecasting much warmer temps and less than normal precip. this fall and into winter. What do you think we are looking at this winter? Thanks again Steve!

    C.J., the average first freeze ranges from November 1 at Ada to about Nov. 10th around Sherman. A frost may occur before the first freeze but there's usually only a few days difference. Thanks for your Weather 101 suggestion and I think I will do one on frost later this week...watch for it! Take Care, Steve

    Yes, This weather is beautiful! However, some of us are suffering from Ragweed and other allergies. So here's my question! When do we typically get our first frost in our area...I'm counting the days??? What does the temperature need to be and what conditions are required for a frost? Weather 101 questions! Thanks, Steve
