Some weakening has been noted over the last hour but the thunderstorms do continue producing isolated heavy rain. Expect the thunderstorms to continue moving east this morning and should be east of Little Rock by 9 am...and should exit the CWFA by noon. The short wave trough being the catalyst for the storms will move east of the area this morning and a ridge will build over Arkansas this afternoon. Models continue to be in good agreement with the mid and latter part of the forecast period...fairly dry. An upper ridge builds over the western U.S. Wednesday providing northwest flow over Arkansas. This ridge will move east through the end of the week and will be over the eastern U.S. by Saturday night. A cold front will move through Arkansas Sunday and bring a chance of showers and thunderstorms. High pressure builds into the area behind the front decreasing rain chances. && .PRELIMINARY POINT TEMPS/POPS...
