Very warm late summer temperatures will continue through Sunday. Isolated showers and thunderstorms will be possible across the mountains each day possibly spreading across the Palmer Divide and the southern I-25 corridor.  A cold front will begin working south across the eastern plains of Colorado on Monday. This front will focus thunderstorm development Monday afternoon and evening. By Tuesday, the front moves through southeast Colorado with much cooler temperatures and a better chance of showers and thunderstorms.   (Please visit http://weather.gov/pub for more information.)
