Excessive rainfall may produce locally considerable flash flooding over parts of South Texas, the western Gulf Coast, and Lower Mississippi River Valley through Thursday. Hot temperatures will persist over central and northern California and the Pacific Northwest through today. Read More >

A strong cold front plowing through the area Saturday night will result in a large temperature swing from Saturday’s highs to lows by Sunday evening. We may see a rare, but not unprecedented, temperature drop of 50 degrees during this time frame. The largest temperature drop from one calendar day to the next in Paducah was November 23-24, 1950, falling from 57 to -2, a difference of 59 degrees! In Evansville, the largest drop was December 13-14, 1901, when the temperature dropped from 65 to 0, a difference of 65 degrees! It is much more common to see a temperature swing of this magnitude out in the Plains states, then it is here in the lower Ohio Valley.
