Forecast: First Frost Won't Hit Until Oct. 19

For those of you excited for the season's first frost, you have a long wait.

According to the Dorchester Times forecasting formula and research, the first frost won't hit Saline County until Oct. 19. 

That's still a month away.

If our prediction holds true, it will only be a few days later than
the average first frost date for our area, which is Oct. 12.

The first "killing frost" won't hit until late October, according to forecast models. This is especially relevant to farmers. 
In both corn and beans, a killing frost occurs at 28 degrees. Once a killing frost hits, plants can no longer move carbohydrates from the leaves, where photosynthesis occurs, to the grain. 

Of course, that also means we will be mowing for several more weeks.

The current record for the latest first frost in our area is Nov. 7, 1956, as some of our readers might recall. (Note: The first frost record for Omaha is even later, occurring on Nov. 13, 1915.)

While night-time lows will drop into the 30s before then, our long-range predictions (using AccuWeather and a few other forecasting services) show that the Dorchester area is going to be much warmer than average this early autumn.

Enjoy the warmth before winter!
