It Could be a Very Wet Week

A large cold area of high pressure is centered over the eastern Great Lakes. A cool air flow is feeding around the the high from the east into the Stateline. A stationary frontal zone is draped across the southern plains, the mid Mississippi valley, across Kentucky and Tennessee. A disturbance over western Missouri is lifting the front toward the north as a warm front. Showers have developed north of the front, and will continue to spread toward the northeast overnight across the Stateline. Temperatures will hold steady in the mid to upper 40's overnight. The wind will be east at 5-10 mph. The Missouri low will move toward the northeast overnight helping to draw warm moist air up and over the front. Scattered showers will linger on Monday morning as the low moves to the south of the Stateline into northwestern Indiana. It will remain mostly cloudy on Monday afternoon with highs pushing into the middle 60's. It will be partly cloudy overnight on Monday night with a low in the upper 40's. On Tuesday, a strong warm front will approach from the southwest, and there will be a good chance of showers and thunderstorms. The surge of warmer and more humid air from the Gulf of Mexico will push temperatures into the middle 70's on Tuesday. The Stateline will find itself located in warm and humid air on Wednesday, Thursday, and possibly into Friday. With fronts nearby, and disturbances moving through the area there will be several opportunities for showers and thunderstorms. There is also the possibility of some locally heavy rainfall totals during the week.
