In Rochester, Minnesota, November temperatures have been mild, peaking at 69°F this Friday, but are expected to drop to the mid-40s by Sunday. A 6-10 day forecast suggests a 60-70% chance of above-normal temperatures in the upper 40s to low 50s, with slightly above-average precipitation. However, from late November to early December, temperatures are predicted to dip below average, especially in southern Minnesota and northern Iowa. This change, linked to sudden stratospheric warming (SSW) and the Negative Arctic Oscillation, can bring arctic air south. While temperatures may soon drop, the situation will be closely monitored and forecasts adjusted as needed. Historical data suggests this could be a significant SSW event, but its impact remains uncertain.
