Winter set to be Colder than Average

The Winter of 2018/19 is looking like one of the colder ones we have seen. More especially the first half and especially December.

This will be due to widespread Northerly blocking where High Pressure pushes North towards Iceland and we are left in a cold flow of Easterlies.

This will likely happen during the period from October to December.

There is a possibility that there may be snow in Ireland even as early as October but widespread low level snow is not likely until December.

Sub zero temperatures will be frequent and expect lows of minus 3 in October minus 7 in November and minus 10 in December.

A low level El Nino event is beginning to take shape and I expect this to signal a milder 2nd part of Winter with heavy rains and gales.

Wintry weather on way

The following 2 weeks will see half and half type weather. Half the time in Ireland it will be mild with temperatures of 10 to 13c while half the time it will be cold with temperatures at 6 to 10c. As is usually the case in this set up there will be more sun on the colder days and more rain on the milder ones.

Frosty nights are sure to feature too with minima down as low as -3c though there is a risk that towards the end of the month values could dip below minus 5.
