The Northerly flow aloft will shift to Easterly later in the day with the FL going to around 3200 meters. A weak upper trough will push in for Saturday with the risk of thunderstorms and rain. We may get lucky with unsettled weather depending on the track of the low and will of the high. Sunday is looking unsettled before the ridge rebuilds for Monday into Tuesday.
