87 degrees Wednesday, 52 degrees Thursday -- not uncommon for October

October 4, 2018

SIOUX CITY -- It looks like Wednesday is going to be a warm day for October, with a high temperature that may climb to 87 degrees. Contrast this with the previous few days, when highs have barely scraped the 50s, and Thursday’s forecast high of 52 degrees.

How unseasonable is a one-day temperature drop of 35 degrees? Not very, says Sioux Falls National Weather Service observing program leader Brad Adams.

“Pretty sharp, dramatic temperature changes” are par for the course in October, Adams said. The record high temperature for Oct. 3, set in 1938, was 96 degrees.

Wednesday’s balmy high temperature is caused by southern winds, he said, while Thursday’s chillier high will be the result of northwest winds.

Typical high temperatures for this time of year in Sioux City would be in the neighborhood of 70 degrees.
