9.12PM - iWeather Online synoptics analyst Fergal Tierney writes: "What looked promising for snow lovers in eastern Leinster this afternoon has turned into a big dissapointment, with the snow well to the north through Louth, Monaghan and southern Northern Ireland. With the circulation centred in the north Irish Sea, airflow on its southwestern flank was from a westerly quadrant. This was fine earlier in the day when the centre was well out to sea, but as it came closer to the coast, this westerly inflow off the freezing landscape cut off the supply of warm moist air it had been feeding off earlier. Further north, where the flow was easterly, showers were allowed to continue to develop, and they have brought a snowy evening to the afformentioned areas.  The east dodged this particular bullet, but there are plenty more left in the magazine for the coming days!"

3.28PM: Fergal Tierney writes: Here's a nice MODIS image of today's convection off the east coast, taken at 1220UTC. The high updraft speeds withing the Cbs can be seen in the overshooting tops in the cirrus anvil, where the updraft's kinetic energy takes it into the stratosphere. I would estimate updraft speeds within these clouds to be in the order of 50mph. Also nicely visible is extent of snow cover throughout the country.

1.24PM - UPDATE RE: Snow on east coast.

iWeather Online's synoptics writer Fergal Tierney reports from Dublin: "It would seem that the earlier explosive convection off the east coast has stabilised now and there does not seem to be much more developement that would suggest a Polar Low. The circulation centre has crossed the Isle of Mann and is now slowly moving westwards through the north Irish Sea. The deepest convection is on its western side, which is probably a result of the interaction of the Isle of Mann with the eastern part of the low, plus slightly warmer sea surface temperatures.

The HiRLAM model forecasts this low to reach a minimum pressure of 1005hPa as it nears the north Leinster coast in the next hour, bringing heavy but not spectacular precipitation rates to Louth, Meath Dublin, Kildare and north Wicklow. It will be interesting to monitor any changes in the actual evolution of the low past this time, as the HiRLAM forecasts it slowly filling towards evening.

I took this image of the impressive Cb Incus associated with the deep convection off the east coast."
