Local Summary for the next five days: A big change in the forecast when we come to the new week. Therefore confidence is low from Monday. The weekend forecast stays much the same with some light showers for Saturday and dry and sunny for Sunday. Temperatures average to very warm over the two days. The big change is the temperatures with much warmer air pushing further north than previously shown. So turning hot to possibly very hot Monday to Wednesday. Heavy showers or longer spells of rain Wednesday evening into the night. The GFS shows the heat being pushed away for Thursday but there's still a chance than even warmer air could be tapped into and lasting longer than shown. So still a very slim chance of extreme temperatures next week although this more likely to be the SE.
