As almost all guidance seems to agree now that wind gusts in exposed western counties may exceed 120 km/hr on Friday, I have opened up this new discussion thread for strong winds Friday into early Saturday.
The global models and the short-range specialty models seem to agree on this and you could find depictions of 120 km/hr or higher gusts near the Mayo coast on almost all models in the 00z suite.
The strongest winds should gradually move east across all regions, arriving on the south coast later Friday and on the east coast early Saturday morning.
This event does not currently look too bad for heavy rain potential but will address that later.
The GFS model also shows further windstorm potential later in the month, in particular around mid-month. This is probably the truer signal of the colder conditions likely to develop than anything you might read in a tabloid about a 2010-style cold spell and snowfall. That's not really supported in any reliable guidance although it could eventually get cold enough for wintry showers (in about two weeks).
