1) What was the dewpoint and wind direction and speed at 1200Z on 30 Dec at 925 hPa in Topeka, KS?
2) Explain the process of how the high dewpoint and wind direction at Topeka helped lead to freezing rain in Nebraska (hint--re-read section on warm fronts in your book).
3)Why does low pressure form at the surface to the east of a trough that is all the way up at 18,000 feet (pg 238-240 book)?
3) Speculate on why you think freezing rain events are so infrequent (hint--look at the diagram of the temperature in the troposphere in your book).
