11/2 Short Term
Forecast updated 2:25 pm EDT - 2 Nov 2011
Today's 12Z NAM shows a large frontal boundary streching from the upper Midwest down towards Texas. This is producing the most precipitation in Iowa and Nebraska. This will make its way towards the Midwest as the currently developing low pressure center over Oklahoma region begins to mature and move northeasterly. The associated precipitation is expected to be focused mainly in southern Indiana and into Kentucky, however Lafayette is expected to see clouds to build through day Thursday with a chance for rain.

By Friday afternoon, the low pressure and associated rain is expected to be affecting the Southeastern U.S.. Meanwhile, Lafayette and much of the central US will be experiencing dry and clear conditions as a large ridge builds into the region. Temperatures are expected to be in the mid 50's for Lafayette Friday. Following this large ridge is the next system that will affect much of the country. By 18Z Friday, this large system develops out west.
