To start Wednesday night there will be heavy rainfall across Munster and coastal areas of Connacht with the risk of spot flooding.
9pm Wednesday night heavy rainfall across Munster, south Leinster and west Connacht.
Between 9PM and Midnight that spell of rain will spread over the rest of Ireland over Leinster and Ulster but as it does so it bumps into colder air across the Connacht and Ulster and could fall as heavy snow for a time on Wednesday night and early Thursday morning just after midnight with the risk of some accumulations in places especially across the northwest and north of Ireland

Come Wednesday night it will be more of a nowcast situation based on temperatures across Ulster and Connacht on where sees snowfall. Temperatures on Wednesday night will range around -1C to 2C across parts of Connacht and Ulster and 1C of a difference could be the difference on where sees snow and where sees a mix of rain and sleet.
Munster and Leinster will see falls of rain with the risk of spot flooding but a mix of sleet or wet snow cant be ruled out across north Leinster.
Some accumulations of between 3cm to 6cm across Ulster look possible in some low level areas but not all with up to 10cm or more over the higher ground areas and mountains.
Another snow and ice warning could be issued on Wednesday around midday depending on what the latest models show and if a warning is issued it will be more than likely be between the times of 8PM Wednesday and 10am Thursday morning.
