A Windy Storm and Heavy Storms in One Day

October 16, 2012; 8:56 AM ET


Note: I will be out of the office Wednesday and Thursday, so no blog post until Friday.

I posted two images below. One shows where heavy storms may develop, and the other shows the wind speeds off the NMM model for the Plains. While that image shows sustained winds, gusts can be as high as 70 mph in the Dakotas into Nebraska and up to 50 mph in Kansas and Iowa.

In the thunderstorm area, the main impact will be damaging winds. With that much momentum, we will probably see a line of storms develop with embedded bow echos and strong winds, perhaps to 65 mph.

I did note in the video that the GFS model continues to show a hurricane hitting Florida after day 10. While it's very far out there, it's still not out of the question that it can happen. There is a big high coming down, and big highs can help spin up storms this time of the year. It will be interesting to see if the Euro will pick up on the storm as we get closer to the time of the event.
