OTTUMWA — The first real taste of winter will likely arrive tonight, with the National Weather Service forecasting 1-2 inches of snow.
This is still early in the season for accumulations, but certainly not unheard of. Ottumwa has received an inch of snow or more in November in one out of every six years since 1989, according to the Midwestern Regional Climate Center’s data. About half of the years show some snowfall in November.
If the forecast holds, this will be the first measurable snow in Ottumwa since April 15, when 0.8 inches fell.
The forecast amounts aren’t guaranteed to be what people wake up to Friday morning. Even if two inches of snow falls, it’s entirely possible many of the early flakes will melt since the ground itself has yet to freeze.
There are a couple rounds of snow possible. The first is Thursday night, mostly between 9 p.m. and midnight. A second chance is possible between noon and 3 p.m. Friday, but it’s not expected to bring much accumulating snow.
The weekend will start off chilly. Friday and Saturday will spend most of the day below freezing, with Saturday’s high only getting up to 33 degrees. Warmer air will move in Sunday, but the forecast high of 42 is still well below normal temperatures.
