Most likely a continuation of the generally unsettled conditions at first with showers or longer spells of rain across many areas, perhaps heavy and thundery in places. However, there may still be some brief drier interludes at times. Further into September, drier weather may become more prevalent, especially in the south and southeast, with any more unsettled conditions tending to become more likely further north and northwest.
