Strong Winds Continue with Severe Threat Saturday Night
5:00 pm Fri 20 October 2017
A tight pressure field will keep it very windy through Sunday; tonight and Saturday the winds will be from the south, and shifting to the north with a cold frontal passage early Sunday morning (before sunrise). There will be a fairly low chance of showers or a few storms overnight and through Saturday afternoon at just 20 percent, and we’ll get into the 80s on Saturday for an unseasonably warm late October day.
Ample moisture, the cold front and a well-developed trough aloft pass through late Saturday into Sunday morning, setting the stage for some locally heavy rainfall and possibly some damaging winds along a line of storms. This line will originate over western Oklahoma late Saturday afternoon and move southeastward into our area overnight. The primary threat is damaging straight line winds although some hail will also be possible. Tornado threat appears very low over Texoma in this linear scenario.
Stiff northerly winds replace the southerly breezes behind the front with gusts around 30 mph. However, the air behind the front really isn’t very cold, and highs should run near 70 on Sunday and well into the 70s on Monday.
We will have an extended period of rather windy weather continuing next week; temperatures will be coo at night but quite mild in the daytime hours.
Both the GFS and ECMWF bring a stronger cold front in late next week, making for a big cool-down for next weekend. But then, that’s a long way off and so much can change in seven days.
