Ames, Iowa – Warm spring weather has been slow to spread across Iowa and the rest of the Northern Plains, causing costly delays for planting, construction and other outdoor activities. Meteorologist Dennis Todey, director of the U-S-D-A’s Midwest Climate Hub in Ames, says changes are underway in the major climate drivers.
La Nina patterns often bring cooler temperatures along with more storms in some areas and droughts elsewhere. El Nino patterns typically do the opposite. Due to the extended chilly weather, many Iowa farmers are a couple of weeks behind in planting and Todey says it will take quite a while to get back to normal growing conditions.
Todey says there is no single cause for the prolonged winter we’ve seen across much of the region in recent weeks.
Many areas in the region have set all-time April records for snow and cold temperatures.
