Most of Indiana is experiencing colder than normal temperatures in the last days of summer. The National Weather Service has recorded temperatures in the upper 30s and low 40s in the past week, which is more than 10 degrees below normal temperatures for this time of the year.
But National Weather Service Meteorologist Chad Swain says the low temperatures are not representative of what is to come in the fall and winter. The prediction for the fall and winter is normal unless other factors like El Nino affect the temperatures.
“It depend on how the El Nino develops because we can end up warmer and drier than normal or near normal depending on how strong it is,” Chad says.
Indiana University Department of Geography Chair Prof. Scott Robeson says the low levels of arctic ice might cause the changes in fall and winter temperatures.
“The arctic sea ice is at it all time record low, at least during the satellite era and so there is some evidence that some of the excess heat is going to come off the arctic ocean, actually could influence our fall and winter weather,” Scott says.
Chad says the temperatures are typical of the below average spells that occurs when the seasons changes from summer to fall.
