Diurnal showers and thunderstorms have dissipated with sunset, and it will be partly cloudy and cool overnight. With dew points still in the middle 50's, and low temperatures expected to reach that level or a little lower overnight there will be patchy fog later tonight in favored low lying rural areas. High pressure will settle into the area on Monday, and it will be partly sunny and delightful with a high in the low to middle 70's. Low pressure will develop over eastern Colorado on Monday night and move to Kansas City by 6 am Tuesday morning. It will be dragging a warm front eastward across western Missouri and western Arkansas. Gulf moisture will feed up and over the warm front, and to the east of the low bringing a chance of showers and thunderstorms to the Stateline Monday night. The low will move across northern Missouri on Tuesday and into central Illinois on Tuesday night. Showers and thunderstorms will overspread the Stateline on Tuesday morning, continue off and on during the afternoon, and taper to a more scattered nature as the low moves to just south of Chicago by the breakfast hour on Wednesday. Weak high pressure will take over at the surface on Wednesday as the jet stream lifts off to the northwest, and an upper level dome of high pressure builds across the eastern part of the US for the rest of the week. On Friday a warm front will stretch from northwestern Iowa across Quincy and Evansville, Indiana. There may be some scattered thunderstorms as Gulf moisture feed northward with the front. It will be very warm an humid Friday, Saturday, and Sunday with a chance of thunderstorms each day.
