(Des Moines) State Climatologist Justin Glisan says Iowa’s six-to-ten and eight-to-fourteen-day weather outlook shows below-average temperatures.
Glisan looks into his crystal ball into December, January, and February, and what does he see?
Glisan says this forecast is tied into the La Nina phase sticking around. What La Nina means during the winter is a cold temperature anomaly in the Pacific Ocean and shifts thunderstorm activity further west in the Pacific Basin, impacting where the jet stream sets up over the United States.
The short-term forecast calls for a high of 30 degrees today, 31 on Wednesday, and 34 on Thursday, with lows in the teens. The average high temperature for this time of year is 37 degrees, and the average low is 19 degrees.
