Confirmed! Heavy enough too. Actually scratch that, not that heavy at all. Sorry about that lads, can't see past my own cataracts.

They're not streamers!! This isn't December 2010. The stuff affecting Louth and northwards is organised precipitation at the southern end of a front stretching from here to the North Sea.

Please have a look at these hi-resolution forecast charts before making further unfounded claims. Any precipitation south of Balbriggan is dying out now, and the models have predicted this (controls to go further in time are in bottom left hand corner of page)

Just to bring home the point about what you are seeing is not Streamers, have a look at the SST of the M2 bouy, it is currently at 9.2c for any streamers (sea/lake effect snow) you need a temp difference of around 13c between the 850hPa temps and the SST there are only -4 to -6 uppers around at the moment nothing near what you need for good sea effect snow.

What you are getting now is what associated with the low system. This is not a 2010 type snowfall.

6 complicated areas of low pressure, Current Low pressure heading roughly for Louth with majority of precip on northern side but lots of moisture boosted up by Irish sea all around this low

In this case it doesn't make sense. The front over Scotland and heading for NI is a warm occluded front (marked as a TROWAL or upper-air occlusion but I can't really see why), where the air ahead of it is going to contain less moisture and heat than the air behind it. This chart is clearer: http://www.weathercharts.org/ukmomslp.htm#t24

The air both ahead and behind the organised precipitation will travel over the same stretch of sea. But if the air ahead is much colder than the air behind, this will make precipitation much stronger. If we had cold air gathered over Ireland itself, or the air coming from Scotland was very cold, this would indeed happen. Unfortunately we're not so lucky with that today. The models show this front gradually weakening as it begins to move northwestwards.
