Thats not telling me why its hard to call, more giving me the odds on calling it.

I was hoping for something a little more scientific than Andy Gray.

It is because there are so many variables that it is difficult.

The data available for this sort of weather is limited and the weather models are having difficulties.

With small changes there are large differences in results. In this case the snow that was falling in the Irish Sea and had been forecast to stay there or maybe skirt the coast came further inland.

ME had said that snow was possible on the east coast. When the variable changed the snow did not have far to move and everything changed in a matter of 90 min.

Is that good enough for you

QUESTION : if the north patterns that are heading southern now collide with the east heading west/south clouds will they intensify more and head inland south or just stay on path all ready on im hoping somehow it heads my way

lol Are you for real?

So you never have to make predictions or plans based on incomplete information?

Was my question not a valid one in a weather forum?

I didnt question anyones abilities to predict the weather, or belittle ME I was genuinely interested in knowing why its so hard to forecast snow from a scientific point of view.

To be honest your attitude in here fu*king stinks.

we finally got a little bit of snow in Dunshaughlin Co. Meath, about an inch of snow fell this evening, I think we were just on the edge of the snow band further to our north there was nothing at all.

Pretty much no. I'm not perfect just close.:)

Snowing very heavy in Naas

today's snow here outside Dundalk was approximately 0 inches and that's definitely inches not centemeters :rolleyes:

to be honest I would love to know too, why is it that a low pressure brining rain is so easy to predict but when it comes to snow anything can happen.

good question whycliff

will we see any snow in the midlands before tomorrow does anyone know?were constantly escaping it

I'll admit i know nothing about the weather but how in the name of God did Met Eireann get it so wrong. Lunchtime today on the radio and no snow expected until late tonight/early tomorrow and yet by 5pm some roads in the capital where impassable. Totally unexceptable imo.:mad:

I originally saw this quote on here by Su Campu and since I've seen it on the Irish Weather Online site by, presumably, the real Su Campu

Consider a rotating spherical envelope of a mixture of gases, occasionally murky and always somewhat viscous. Place it around an astronomical object nearly 8000 miles in diameter. Tilt the whole system back and forth with respect to its source of heat and light. Freeze it at the poles of its axis of rotation and intensely heat it in the middle. Cover most of the surface of the sphere with a liquid that continually feeds moisture into the atmosphere. Subject the whole to tidal forces induced by the sun and a captive satellite. Then try to predict the conditions of one small portion of that atmosphere for a period of one to several days in advance.


It's obviously quite global etc., but hopefully you can grasp why you can't just look in the sky and tell what's going to happen tomorrow or the day after. Furthermore, just look at the radar (Met Eireann, RainToday etc..) and see how showers appear, break up, disappear etc. Even knowing that a low pressure this/that is on the way, different miniscule local elements change things.

It's not easy. If it was, being a forecaster wouldn't be a particular job.

Wow. Almost as deep as Jupiter now.

The North of Dublin and parts of South Dublin seem to have got a real bashing this morning, this afternoon and this evening. West Dublin has got quite a bit as well but less than other parts IMO.:D

And my comment about it being as easy as picking a premiership match was fine. This is a general snow discussion chat. There is a specific forecasting forum if you would like to try that.

Was not trying to be smart. (so sorry for offending your sensibilities)
