Northerly air flow this weekend will cause mainly dry and breezy weather to continue. Temperatures should be cooler than in recent weeks, although still near to above normal for many areas. Following some clouds and a slight chance of rain in the east on Saturday, Sunday could be a rather sunny day. Monday morning may be quite chilly if winds are calm at that time. High pressure is expected to build strongly into the region early next week, leading to calm and warming day-time conditions. However, the pattern may change later next week, as weak storm systems attempt to move in from the northwest. Low temperatures should be warmer later next week, although highs at the coast are likely to decrease. By next weekend, a more unsettled and potentially stormy pattern could take hold. Overall, the details of the upcoming regime shift are unclear at the present time.
