Showers and thunderstorms will accompany a strong upper level low pressure system and a cold front on Saturday. Some thunderstorms will likely become severe, mainly during the afternoon and evening hours, with the best chances occurring along and east of the Interstate 35 corridor. In addition, locally heavy rain could cause flooding in some areas. Severe weather should move east of the region around midnight Saturday night, but showers and occasional non-severe storms may continue overnight behind the front. Rain chances will come to an end Sunday morning, with cool and dry weather Sunday afternoon.
