As an upper level trough digs its way into the eastern United States, a mid latitude cyclone pounds the northern plains as it's cold front drapes across the SE bringing us our first real taste of fall weather. Expect the cold front to bring us some thunderstorms tonight but once the rain subsides, cooler drier air will fill in behind it as the winds shift to the north. This will keep us rain free through most of the week. Lows will reach the lower 50's and even the upper 40's in some areas. Highs will remain in the 70's tomorrow, then stay in the 80s through most of the week. This trough will also be pushing T.D. Karen away from Louisiana. Be prepared for some rain tonight, then beautiful conditions for the next week.
