November Warmth - Winter Outlook

November has maintained the above average warmth. It's unusual for Oshkosh to experience such warmth in November. As of today, this November ranks SECOND all-time for warmest mean temp. However, there is a cold snap forecast to break through sometime next week and settle in as we move onto December. With that in mind, November could fall out of the top 10. We'll see.
