Autumn is just around the corner and there is a clear pinch in the air this Friday morning.
Although most of the week has been mild and humid, today we see a change in the conditions, with temperatures dropping to 5 ° C overnight.
A Met Eireann predictor said: "Cool and windy today with scattered showers.
"The showers are spreading quite a lot in the afternoon with the risk of an isolated storm in the northern half of the country.

"Top temperatures of only 13 to 16 degrees in fresh and windless west to northwest winds."
Friday night will be "pretty cold" with temperatures as low as 5C in moderate northwest breeze.

Saturday marks the start of Pope Francis' journey to Ireland and it is predicted that there will be "good sunny periods".
One predictor said: "It looks like Saturday is dry in most areas with a mix of clouds and good sunny periods.

The top temperatures are between 15C and 18C.
On Saturday night the rain will pour in from the Atlantic Ocean and although the temperatures will drop to a low of 9C, it will not be as fresh as Friday.
Those who visit the Pope on Sunday have to take a brolly, because in the morning there will be & # 39; bursts of rain & # 39; in the whole country.
With Eireann said: "However, it is expected that the rain will soon disappear to the east with the last rain that is cleared on the east coast at lunchtime.
"Clear spells and scattered stormy showers will follow as the rain diminishes with the best of all the sunshine expected in eastern counties during the evening.
"Highest temperatures between 16C and 20C, the best values in the east of the country.
