Unhealthy air due to fireworks to linger this morning

Unhealthy to hazardous air quality has developed over much of eastern Nebraska and southwest Iowa early this morning, and these conditions will likely linger until around 9 AM. The poor air quality is the result of lingering smoke from Saturday evening fireworks activity which has become trapped near the ground by a
temperature inversion and stagnant air flow pattern. Conditions are expected to improve after 9 AM as increased atmospheric mixing allows for the dispersion of the smoke.

Those with respiratory concerns should avoid outdoor exposure until conditions improve later this morning.

Peak tornado season is ending and Iowa’s numbers are, thankfully, way down

Weather

July 1st, 2020 by Ric Hanson

(Radio Iowa) — The end of June means the end of peak tornado season in Iowa. Twisters can strike during any month but they’re typically the worst here during April, May and June. Meteorologist Brad Small, at the National Weather Service, says it’s been a relatively quiet season for severe weather in the state. “Tornadoes have been down a little bit. We’ve only issued 14 warnings in the Des Moines/Central Iowa forecast office. We don’t really keep too many numbers on that as far as records, but that’s on the low side,” Small says. “If you look at severe thunderstorm and tornado warnings combined, we’re in the lowest 25% of all the years since the mid-80s.”

There have been 23 reports of tornadoes in Iowa so far in 2020. In all of 2019, there were 54 tornadoes, while in 2018, the total reached 69 twisters. Conditions simply haven’t been conducive for many tornadoes this season, Small says, not that he’s complaining.  “The pattern just hasn’t set up too well,” he says. “You’ve got to have a lot of instability and a lot of wind shear combined. There’s been some episodes where it’s been cooler, so we haven’t had a lot of that instability earlier this spring. Those two elements just haven’t come together too well.”

Small advises Iowans not to get complacent as severe weather, including tornadoes, can develop in fall and winter. Iowa has even recorded December and January tornadoes, though they’re rare. No severe weather is likely for the foreseeable future in Iowa. Forecasters say warm and humid conditions will persist into the 4th of July weekend.

Beware as the ‘Godzilla’ dust plume is likely to reach Iowa this weekend

News, Weather

June 26th, 2020 by Ric Hanson

(Radio Iowa) — A massive thunderstorm in Africa’s Sahara Desert created an enormous dust cloud thousands of feet high and the plume that’s made a six-thousand mile journey across the Atlantic Ocean may impact Iowa this weekend. State climatologist Justin Glisan says it’s an exceptionally rare event.

This satellite photo provided by the National Oceanic and Atmospheric Administration, NOAA, shows a could of dust coming from the Sahara desert arriving to the Caribbean Monday, June 22, 2020. The massive cloud of dust is blanketing the Caribbean as it heads to the U.S. with a size and concentration level that meteorologists say hasn’t been seen in roughly half a century. (NOAA via AP)

“They’re calling it the Godzilla plume because we haven’t seen a dust plume from West Africa stay together in the spatial scale that it is in over 50-to-60 years,” Glisan says. “It’s a unique phenomena that we’re seeing.” People who have compromised immune systems, especially those who may have COVID-19, are warned to stay indoors as much as possible for the next several days.

“We should see some affect of the plume in basically air quality, more particulate in the air,” Glisan says. “People with breathing problems will see increased aerosols near the surface and that will produce breathing problems.” Depending on how the jet stream moves the dust across the country and into the Midwest, photographers in Iowa may have a golden opportunity to shoot some gorgeous pictures thanks to the plume, especially at dawn and dusk.

“Because you have that particulate in the air, it acts to scatter sunlight towards the prettier colors of the spectrum, red, pink, purple,” he says, “so we should see very lovely sunrises and sunsets.” Car washes in Iowa could be busier next week, as Glisan says we may see a thicker coating of dust on our vehicles than usual, especially if they’re not in a garage. Outdoor plants, too, will get dusty, although farmers likely won’t need to be worried about their crops.

“We won’t see major affects on agriculture, but, if you think about how you have dust in the atmosphere, that limits the amount of sunlight that gets to the surface and to the leaf area of corn and soybeans,” Glisan says. “It might limit photosynthesis but being a short-lived event, I don’t think it will have a major impact on things.”

The skies may not appear as blue for the next several days either, he says, as the dust makes the air far above us whiter, much like when there’s a big forest fire in Canada and the smoke is carried here on the wind.
