Yup. It's time. Brood X of the 17 year cicada is due mid-May through mid-June of this year.
The last time I experienced this phenomenon was in Cincinnati and they were so thick that cars would overheat on I-71/I-75 due to the radiator being clogged with these guys.
I've not had the pleasure of flying through a swarm of these but it stands to reason you should expect an obscured windscreen, perhaps a blocked pitot tube and an extra hour or two cleaning the leading edges of leftover cicada parts.
I understand there are a number of recipes available for the more adventurous.
A regional map is included. We'll have to ask the FAA if they mention them in the ATIS reports.
