Didn't think i would have the privelege of opening another thread for an upcoming snow event this winter, how wrong was i.

A near perfect winter snow-storm scenario
Midnight Tuesday



Overnight precipitation will tend to die to drizzle away from more southern and far northern parts as the Low pressure system reorganises itself.

With the low pressure centre meandering around Dublin bay over the coming hours with a slack flow around the centre until around midday tomorrow.

From around noon tomorrow the storms gradient will steepen as a result of the ingestion of some very cold air from the north, winds will veer from variable and strengthen to Northerly gales and severe gales along some eastern coastal districts. Meanwhile temperatures will drop sharply through the day along with dewpoints.

During morning a band of moderate rain with snow on mountains will stretch from ulster down through the Leinster coast.

Towards 6pm as a steep gradient develops as a result of the interaction between the cold and warmer air extremely heavy precipitation will develop over Ulster and push south through much of the country. The precip will readily turn to heavy snow through the evening and spread south through the night.

Winds will will strengthen to gale force Northerly as the heavy snow pushes south. Temperature will drop to 0c or just below towards dusk with moderate and heavy falls of snow even at this stage to low lying areas.

The snow will moderate overnight and push eastwards but will continue till around midday Wednesday in eastern and northeastern areas.

Temperatures Wednesday will struggle to reach 2-3c as the accumulations of snow thaw quite slowly as cold northerly winds follow behind the storm system.

Accumulations of snow over the Mournes mountains could exceed 50 cm's with falls of over 20-30cm's over the Wicklow mountains.

Accums of upto and potentially above 5-10cm's will occur widely through low lying areas of Leinster, the Midlands, Ulster and some other areas during Tuesday night into Wednesday.

I would urge extreme caution as this could well be one of the severest single weather events of this winter.

We are nearing April however and the snow should thaw relatively quickly during Wednesday but with the very cold airmass still in place and little sunshine likely, the thaw may not occur as fast as would normally be expected following a late March snowfall.
