October Weather Outlook

Written by Jay Hobgood, Ph. D., The Ohio State University


The temperature will be above normal during October.  Precipitation will be near normal for the month. 


October will start off with record heat over Ohio.  A high pressure system over the southeastern U.S. will produce southwesterly winds which will transport unseasonably warm air over the state to start the month.  The high pressure system will break down in a few days and the weather will return to a more normal pattern. 

Weather systems will move across Ohio periodically and they will cause large swings in the temperature from warm to cold and back to warm again.  The extreme heat at the beginning of October will likely cause the temperature to average above normal for the month.  October is typically one of the drier months of the year.  The weather systems moving across Ohio are likely to drop near normal rainfall during October.
