Hazy smoky skies could stick around awhile

News, Weather

July 30th, 2021 by Ric Hanson

(Radio Iowa) – Almost all of Iowa has been under an air quality alert today (Friday) as smoke from wildfires outside the state has created a hazy sky. National Weather Service meteorologist, Rod Donovan, says the upper airflow pulled the smoke in.  “Over the last 24 hours as a lot that western smoke from the wildfires across the northwest U-S — and especially into western Canada as well — we’ve gotten into more of what we consider a northwest flow, and it allows that smoke to diver back across Iowa,” Donovan says. “We’ve even seen some of that smoke actually mix toward the ground itself.”

It’s the first day this week that at least part of Iowa isn’t under a heat advisory. Donovan says one benefit of the smoke in the air is cooler temperatures. “Actually filters some of the sunshine and can certainly keep temperatures down a few degrees…even today we are down two to three degrees, just basically due to this filtered sunshine,” he says. He says the airflow also brings in some cooler air, and it is a pattern that is going to stick around a bit.

He says we will be in the northwest flow for the next several days and probably have the smoke move into Iowa into the middle of next week. Donovan says the smoke isn’t an issue until it mixes down. )”So, hopefully, we can keep most of this smoke aloft away from where it can cause respiratory impacts and things like that,” Donovan says.

The Iowa D-N-R keeps track of the air quality and you can find out more on their webpage at iowadnr.gov.

UPDATE:Flash Flood Watch issued for parts of western/southwest Iowa tonight

303 PM CDT Fri Jul 30 2021


The National Weather Service in Omaha/Valley has issued a Flash Flood Watch for portions of Iowa and Nebraska from 9 PM CDT this evening through 9 AM Saturday.



* From 1 AM CDT Saturday through Saturday morning.

* Heavy rainfall of 2 to 4 inches will be possible in the watch area. Local amounts to 5 inches will be possible. This could lead to localized flash flooding; especially in urban areas.

* Thunderstorms will develop by this evening in northeast Nebraska and move southeast overnight. Due to the high amount of moisture in the atmosphere these storms have the potential to produce very high rainfall rates. Although it has been dry lately, this heavy rain may still cause flooding, especially in urban areas.


You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
