An upper level low pressure system will deepen north of the Great lakes by mid week, and cold air from northern Canada will spill southward into Kansas on Wednesday. A surface high pressure system will build into southern Minnesota and Iowa by Thursday afternoon, resulting in northeast low level winds in Kansas. As the cool air flows up the terrain, it will become saturated, and widespread cloudiness will develop. An upper level trough will move from the tropical Pacific to the central plains on Thursday, and widespread lifting over the cold air will support development of light rain across much of southwest Kansas. The combination of light rain, cool northeast low level winds and widespread cloud cover will keep temperatures in the 50s in most areas on Thursday. Although most locations will receive measurable rain from this event, total rainfall generally will be less than half an inch. Expected high temperatures for Thursday are depicted below.
