A watch is issued when a dangerous situation is possible, but a PDS, or “particularly dangerous situation” watch indicates a level of certainty for high end severe weather that should give residents within the bounds of a watch pause. The SPC has issued a PDS Severe thunderstorm watch for Northern Kansas and parts of southern Nebraska, including Lincoln.
Usually, PDS watches are for tornadoes, when
The text of the watch includes a threat for winds of 85mph or greater, while there have already been reports of gusts to 80mph as the squall exited Colorado. This storm is going to rage overnight, which means it will likely take many people off guard. Unlike tornadoes which usually bring sirens, but ultimately pick and choose their way across the countryside, this storm will not trigger warning sirens in every county, despite the risks, and will likely impact more residents. The PDS attribution should make all emergency personnel in the area take notice and be ready to respond as necessary.
It’s going to be a noisy night.
