Change couplet

26 Oct 2011 05:56 AM
Our weather has made a dramatic change after a very warm Tuesday followed by a cold front which has dropped our temperatures 10-20 degrees versus yesterday morning. The featured map presents an analysis of this change showing the area of cooling near Iowa paired with an area of warming over the mid Mississippi valley. This couplet is due to air mass translation as the area of warm air moves east and is replaced by a cold air mass. Our high temperatures look to be stuck in the 50s until a slight warm up next week.
