(KPLR) - A cold front is now moving into the Ohio Valley.  After a high of 60 this morning, northwest winds have steadily knocked temperatures down.  The cold front has cut off the moisture, so the clouds will clear this evening allowing for radiational cooling to drop temperatures overnight near 32.  If you have errands to run, grab a winter coat.  Any delicate vegetation that has survived the earlier bouts with frost, will need to be covered this evening.  Good news for Thursday as sunshine returns.  Highs will warm from 55 Thursday into the 60s for the weekend.  It looks like a nice autumn weekend with warming temperatures and dry weather.
