Before we get to October 2018's forecast, let's see what is average for an October in Omaha. This time of year, it's normal for the cold air to our north and the warm air to our south to use Nebraska and Iowa as a battleground. This means we get a lot of volatility, or ups and downs, in the weather. 

When you average the afternoon high temperatures every day in October over the last 30 years at Eppley Airfield, you come up with an average high of 65 degrees. Average out the lows, and you get 42 degrees.

As for rain, we average 2.15 inches.

We know the first week of October will bring a taste of summer, with Omaha possibly hitting 90 degrees on October 3rd. Summer isn't here to stay though, as the cold air quickly fights back and wins again, at least for a few days.

It looks like it could be a fair battle between cold and warm the rest of the month too. The Climate Prediction Center's (CPC) outlook for October shows Nebraska and Iowa falling right between areas that are more likely to be above average and those more likely to be below average.

As for rainfall, the first week of the month could bring multiple inches of rain to parts of the region. The CPC thinks the wet pattern could be common across the Midwest this month. It's outlook shows Nebraska and Iowa likely coming in above average for rain by the end of the month.

But with an average of only 2.15 inches... that's not too hard to surpass in the rain buckets with a couple good storms.
