Severe and Snow

It looks like there really isn't too much to add from my last blog post. The snow threat has increased substantially with all of the thickness values now turning over to all snow. The soundings in South Dakota look very promising for snow as well, along with momentum transfer of up to 60 knots of winds! What does this mean? Blizzard conditions can be expected from Rapid City to Mitchell, SD and north. I wouldn't be surprised to see snowfall totals in the 6-10 inch range in much of central S/N Dakota.

The severe threat is still considerable, however the moisture return actually does not look like it will be has high as I expected. The tornado threat is still there, and we could see a few isolated tornadoes in the central northern Oklahoma to southeastern Nebraska region as the storms fire in the afternoon on Wednesday. Quickly, however, a strong squall line will develop resulting in a much greater wind threat. I wouldn't be surprised to see a vast area of 70 mph wind gusts as the line tracks through eastern Kansas/Oklahoma/Nebraska into Missouri/Iowa/Arkansas.

This is going to be a major fall storm. The strongest of the season so far. If you are in the Dakotas, make sure to keep indoors. If you are in the area with a severe threat, make sure to keep that weather radio on in the event severe weather threatens your area.
