WORTHINGTON — While the anticipation of a break from the stifling heat southwest Minnesotans and northwest Iowans have endured over the last several days is near, people may want to stay inside for just a bit longer.
Around 2 p.m. Friday, the temperature was 90 degrees with a dew point in the upper 70s, the National Weather Service of Sioux Falls, S.D. reported.
As of Friday afternoon, the southwest Minnesota and northwest Iowa regions continued to be under an excessive heat warning, which requires heat indices of 105 degrees or higher.
“By late (Friday) afternoon, we should be as high if not even a little bit higher than yesterday,” said NWS meteorologist Peter Rogers. The heat index topped out at 5 p.m. July 18 at 103 degrees.
Friday afternoon’s heat warning is expected to expire around 10 p.m. Then what lies between the area’s heat and Saturday’s mid-70 degrees are storms that are expected to move through the area overnight and into tomorrow morning. Rogers said the storms that could include wind and hail could be strong to severe across southwest Minnesota.
According to the NWS, Saturday high temperatures are forecast at 76 degrees with dew points in the 60s. Sunday is anticipated to have a high of 75 degrees with dew points in the 50s.
“When you’re looking at the weekend as a whole, Sunday is definitely going to be the most comfortable day,” Rogers said.
For context, Rogers said feelings of discomfort if not misery due to the humidity is caused when the dew point rises above about 70 degrees.
