The passage of a cold front Wednesday night will bring cooler and less humid conditions the rest of the week.
High pressure is building southward across the Great Lakes and upper Ohio Valley, resulting in a northwesterly flow of pleasant air after a week of heat and humidity, which ended with some gusty storms. The rain was much needed in a dry, hot summer.
Temperatures will only reach the upper 70s today in most places, and low temperatures will fall into the comfortable upper 50s early Friday morning.
Sunshine and dry weather will continue through the weekend into early next week, with a gradual warming trend. The next chance for showers or storms will not arrive until Tuesday.
