September to end on a High?

The Area of High pressure that is bringing the current welcome spell of fine and settled weather (albeit with cool nights) looks like fighting until the end of September at least. It may not be over us but it will be near Ireland and the UK possibly to the Northeast with the Autumn Lows kept out frustrated in the Atlantic wondering whats happened their ease of access over the Summer. Temperatures of 17c are likely a lot of days till the end of the month but the monthly average temperature is down on average due to some uncharacteristically cool nights. In Ballyhaise in Co Cavan the temperature dipped to 2.2c on 13th September!
