• Iowa experienced one of the wettest meteorological springs on record for most of Iowa (March-May 2024), ending a long drought that had persisted since 2020.
  • It was the first time since June 2020 that there was no drought anywhere in Iowa, with only abnormally dry conditions remaining in some areas.
• Precipitation levels were in the top 10 wettest on record for 7 out of 9 climate divisions in Iowa.
• The wet spring helped replenish soil moisture, stream flows, and shallow aquifers, though deeper aquifers will take years to fully recover.
• Growing degree days were above average while stress degree days (temperatures above 86°F) were slightly below average, providing favorable conditions for plant growth.
• The last frost occurred around late April in central Iowa, allowing an extended spring growing season.
• Vegetable growers reported good germination and growth without needing to irrigate due to the ample rainfall.
• However, some growers fell behind on transplanting starts and succession plantings due to the wet fields.
• Succession planting of crops like cucumbers, zucchini, and radishes was impacted by the delays.
• Overall, it was described as an archetypal, pleasant spring after coming out of a multi-year drought.

We discussed the rare occurrence of the Northern Lights (Aurora Borealis) being visible in central parts of the United States, including Iowa and Missouri on May 10-11, 2024.

• The Northern Lights were visible much farther south than usual, including central Missouri, due to a powerful G5 class geomagnetic storm caused by coronal mass ejections and solar flares from the Sun
• Justin, vividly recalls seeing the Aurora in Columbia, Missouri, around 20 years ago during another strong geomagnetic storm, describing it as brighter than the ones he witnessed in Fairbanks, Alaska
• The hosts explain how the different colors (green from nitrogen, pink from oxygen) are produced by the interaction of charged particles with gases in the Earth's atmosphere
• They discuss the potential impacts of such space weather events on GPS, telecommunications, and electrical grids, necessitating precautionary measures like shutting down satellites and power grids
• There were some agricultural impacts reported, like disrupted GPS on farm equipment during the planting season.
• The conversation also touches upon the hosts' humorous anecdotes and pop culture references related to the Northern Lights phenomenon.

• The hosts discussed the weather history of Iowa in 1951, which saw unusually heavy precipitation after a dry start to the year, echoing the current wet conditions in the state.
• They provided a forecast for the coming week, predicting 1-2 inches of rainfall from thunderstorms across Iowa, with temperatures in the low 80s during the day and low 60s overnight.
• The long-range outlooks showed a warm signal for the next 6-10 days, followed by a cooler period in the 8-14 day range, with near-normal precipitation expected.

• They discussed a derecho (widespread, long-lived wind storm) that impacted Iowa on the previous Thursday night/Friday morning, causing damage from high winds and tornadoes.
• The hosts provided detailed explanations of derechos, including their definition, types (progressive vs. serial), and the atmospheric conditions that lead to such events.
• The recent derecho in Iowa had tornadoes and high winds concentrated in the central and eastern parts of the state, causing damage to structures, trees, and outbuildings.
• The hosts provided a comprehensive explanation of derechos, which are widespread, long-lived wind storms. Key points:

• • A derecho must travel at least 400 miles, be at least 60 miles wide, and have a majority of wind gusts 58 mph or greater within that swath.
  • There are two types: progressive derechos (like August 2020) and serial/cold front-driven derechos (like December 2021 and the recent event).
  • The December 2021 derecho had 63 tornadoes and exceptionally strong non-thunderstorm gradient winds due to a steep pressure gradient between a low and high pressure system.

• They also discussed the impact of the recent heavy rains on field tiles, ponding, and the potential for replenishing irrigation ponds.
• Impacts on specialty crops like high insect pressure from overwintered pests, strawberry peak, tomato spotted wilt virus found in greenhouse marigolds.
• Some vegetable growers are facing challenges getting liability insurance coverage for leafy greens production due to recent foodborne illness outbreaks.
