ISSUED 9AM, 5 DEC, 2012
This is an advance advisory in relation to growing signals that Ireland may experience some wintry weather from mid-week next week. Confidence is around 50-55% at present. The forecast will be subject to change in the coming days but we feel it prudent to issue and advance advisory at this point.
The Meteo Times (TMT) Senior Forecaster, Peter O’Donnell comments on the potential for a wintry outbreak from mid-week next week:
“There are growing signs that an episode of possibly severe wintry weather will set in around the 12/13 December and could potentially last towards Christmas. The depth of cold appears to be in the range needed for snow and at times the computer models have fairly promising gradients and synoptic. Therefore, at this admittedly long range we are now for the first time this winter seeing a better than 50-50 chance of wintry weather from the whole model consensus. I would not say this looks quite as intense as the first part of the Nov-Dec 2010 outbreak and I expect it to be the first of several attempts that might get more powerful later in the season. My suggested quote would be "potential for accumulations of snow in parts of eastern Ireland and on hills further west" and not speculating about amounts yet, some of the maps have the look of a few cms anyway.
Main question now is whether successive model runs will develop this theme or back away from it as they did about a week ago, looks a bit more plausible this time. First snow at low levels around the 12th?”
