Could be a long ceremony, possibly well into April with some 'rolling in the snow' exercise included.

Make sure you're all wrapped up well and have plenty of bonfires going...
Weather Forecast for Ireland from Monday, 25 March 2013 until Sunday, 31 March 2013:
ALERT for risk of locally heavy snowfalls and the certainty of unseasonable cold, frosts and icy roads at times from later today in north, to mid-week central and south, any snowfall most likely in parts of north Leinster and Ulster, possibly extending to midlands and south coast at times. ADVANCE ALERT for risk of wintry precipitation over the Easter weekend period, currently assessed as "moderate" or about 50-60 per cent likely as guidance is somewhat split on this outcome.
TODAY ... Mostly cloudy with cold east winds, some sunny intervals more likely in the west, some wintry showers including some accumulations of snow mainly in north Leinster and east Ulster (Meath, Westmeath, Longford, also Cavan, Monaghan, Louth) and by later today also near south coast and in Wicklow and Wexford. Amounts generally light but potential for 5-15 cm locally in streamers. Highs about 2-4 C, winds E 40-70 km/hr.
TONIGHT through THURSDAY ... The overnight hours will be bitterly cold all through the week, and lows could reach -8 C near snow cover in the north and otherwise near -5 C although closer to -2 C east coast and south coast due to the slight modifying effects of open water. Tonight, snow may continue in some places from developments this afternoon, watch for updates. In general, for overnight hours this week, some snow could develop at times mostly during evening hours continuing on from daytime developments ... The days mid-week will be very cold with about equal mixtures of cloud and sunshine although tending more sunny in the west, with greater risk of snowfall in isolated streamers near east coast, south coast and parts of Ulster. Amounts with these could at any time reach 5-15 cm in rather limited regions. Over time, Meath, Dublin, Wicklow, Waterford and inland southeast, east Ulster are regions most likely to see at least slight accumulations during the period. Details may change as we pick up indications of trough features or better short-term satellite and radar indications. We expect a similar outcome to that seen two weeks ago where one or two locations saw significant snow, quite a few saw snow without much disruption, and many (particularly west) saw just a few flakes in the wind or no snow at all.
FURTHER OUTLOOK for EASTER WEEKEND ... The outlook remains uncertain since model output ranges from continued cold with snow potential (in south mainly inland, central and possibly north), sleet or rain potential (in south), to dry cold, to other solutions that include gradual warming and showers. The most likely outcome based on a weighted blend of reliable guidance is for intervals of sleet or snow turning more to rain but only near the south coast for that, through the period. It should be noted that there is potential for a disruptive snow event in the mix, most likely on Good Friday and across inland south and east. We currently assess this risk at about 30% likely, with another 40% chance of light non-disruptive snowfall and/or sleet.
Any sort of return to more normal by then April weather appears to be pushed back to about the second week of April now. The culprit remains the very strong blocking high over Greenland and nearby parts of the north polar regions including a lot of northern Canada and far northern Europe -- all over that extensive region pressures are 20-40 mb higher than usually seen and while these pressures might not be that notable for any one location, the extent of them is unusual and is maintaining a frigid easterly flow almost around the hemisphere now (although it pushes well north in our time zone, so we are getting a more modified version of this severe cold, however, eastern and central North America are just as far into the deep freeze if not more so, for example south of Chicago there has been a foot of snow in the past day or two. Last year it was close to 27 deg C there.)
