Colder weather over Ireland next week have storm Ciara passes with possible snowfall
This weekend the weather is going to become rather unsettled with heavy rainfall leading to the risk of spot and localised flooding and very strong winds on Saturday and the risk of severe and damaging gusts on Sunday when storm Ciara passes of the north of Ireland and over Scotland.
Once this passes through on Sunday evening and night colder air will filter in behind.

On Sunday night and Monday morning colder polar maritime air will push toward Ireland bringing with it colder air temperatures and colder upper air temperature jumping from around 4C to 6C 1500 meters above sea level early Sunday to around -4C to -5C on Sunday night and Monday.
This colder air is crossing the Atlantic all the way down from Canada and even though it does make that long trip across the Atlantic it still could give a high risk of some snow for places over the early days of next week.
On Monday as that colder air filters down across Ireland showers will turn wintry with a mixture of rain, sleet and hail with the risk of thunderstorms also which is common in this sort of set up this time of year, Over higher ground and over the mountains on Monday these showers will fall as snow and could give blizzard type conditions due to the strong winds staying with us over much of Monday gusting in some places between 80km/hr to 120km/hr with stronger winds over high ground areas and mountains.
On Monday night that very colder upper air temperatures stay with us and with evening time and night time approaching on Monday showers at lower level look set to turn increasing wintry with falls of snow possible with some accumulations highest risk areas been Connacht, Ulster and west Munster.
Due to the strength of the winds these showers could then get blowing further inland with some wintry showers possible further east also.
Upper air temperatures will be at there coldest on Monday night and Tuesday with temperature as low as -5 to -7C sitting across some parts of the country (Note again when I say upper air temperatures I am talking about 1500 meters above sea level) which is one of the factors that helps us tell what these showers could fall as (Rain, Hail, Sleet or Snow). The risk of thunderstorms again will follow on Tuesday.
Tuesday night into Wednesday morning again could also see falls of sleet or snow to lowers levels but come Wednesday morning them upper air temperature aren’t as cold based on latest data dropping back to around 0C to -3C in places which cold give more of a mix of rain, hail or sleet to lower levels with snow over the mountains.
Another factor we look at next week is the dew point temperatures which look set to range between 0C to -4C across Ireland which is another factor that would be good for falls of snow from Monday into Wednesday morning.
Sea level temperature which is the level we are at also look good between 3C to -2C. Best temperatures to see snowfall is when the temperature is at 0C or lower.
Another factor to add in next week that will make it rather cold is the windchill factor or the real feal factor which could get down to -4C in some places by day and as low as -7C by night in places so it will feal rather raw next week.
Overall the best period for seen wintry falls of snow to low levels next week at this stage looks set to be from Monday evening, Tuesday and early Wednesday morning with some places particularly across the west, northwest and north seen possible accumulations and icy conditions on roads.
