A slow moving but strong cold front will bring widespread showers and thunderstorms to the region over the next few days and nights. The rain will overspread northeast and central Missouri tonight, and then push across the remainder of the region on Tuesday. By the time the wet weather winds down on Tuesday night, rainfalls of around one inch will be common, and heavier amounts are expected in some areas.  In addition to the showers and storms, the cold front will bring yet another round of chilly April weather to the area, with highs dropping into upper 40s and 50s in its wake.
