Isolated morning showers will likely end before 10am. By afternoon, heat indices will reach the 100 to 105 range with hottest values across central Kansas. Thunderstorms will develop over eastern Colorado later tonight and spread into the lower plains overnight. Some uncertainty exists as to how far north the development will be as some models maintain most of the activity across west central into central Kansas, while others favor southwest Kansas early in the evening, and then driving most of the storms into the panhandles. So the greatest chances for strong winds, heavy rain and small hail will be over the southwest counties mid evening, with chances farther east, later in the night.

Today’s high will be near 100 with an overnight low around 73. Temperatures will be near 100 each day Sunday through Tuesday, with additional chances for scattered thunderstorms. A cool front will cross the region Tuesday night. Temperatures will turn slightly cooler for Wednesday and Thursday.
