High Wind Watch

Posted: 14 Dec 2021 05:34 AM

The upcoming wind storm along with any thunderstorms continue to be of top concern among weather forecasters for Wednesday into Thursday morning. The NWS issued a somewhat rare High Wind Watch for much of Iowa. The featured chart presents the number of such events with data back to 2006. For far southern and northeastern Iowa (both currently under the watch), there's very few other event during this period. Other portions of the state are necessarily not all that more frequent as this alert type is reserved for the most extreme of events. Any storms that are able to form will likely only increase the wind speeds as such storms typically transport higher velocity air aloft to the surface. While very strong to damaging winds seem to be a given at this point, the tornado threat remains less certain but will need to be closely watched. Storm motion will be very fast and these storms will come during the night time.

Good = 21
