It’s a firmly ‘no two days are the same’ weather pattern. We still hold onto the Atlantic pattern hence the highly changeable night of the weather but colder air is now involved unlike last month. One night features mild, wet and windy, the next it’s clear, cold and frosty like this morning.

Last night was Northern Ireland’s coldest of autumn with a low of -4.6C recorded at Katesbridge.

Tonight we’re back to the wet, windy and warmer!

The reason for the rollercoaster temperature regime is all down to the continuation of an Atlantic pattern which keeps things transient but colder, arctic source air has came down and is now caught in the mid latitude flow hence the hill snow and colder feel. Colder air being pulled in on the rear of each passing Atlantic low followed by brief ridging means chilly nights.

Next front is now spreading rain into North and western areas.

By Friday, we’re back in a colder NW flow with the return of hill snow but the next feature is already sliding into Ireland during the afternoon.

Friday’s weather in Ireland is Saturday’s for the UK.

A former tropical system arrives Saturday bringing the next round of wind and rain before another push of cold air moves in.

Could see significant snowfall over the Highlands with the system tracking across the central swathe of the UK which keeps Scotland in the cold air.

Here’s hoping this pattern can materialize during the second half of the month.
