Will Navan get a bit of snow tonight. Can anyone answer?

Unlikely before 2am according to the met eireann precip charts although you are just on the edge of that Duff. Everything is coming from NE to N so you would need to see precip heading your way from Co Down direction to be getting anything. Showers may develop later in the night. Maybe MT mentioned this in his last post about half hour ago.

keep an eye on the met radar or any o these

Lovely thanks for the reply. Hopefully we will have a bit of luck. We got hardly anything at all last night. Was a little bit on the ground this morning. Hopefully we get that percip.

I can't see any showers further North at all just for the South now with the unstable air!

I will work on a better base map for future efforts, that one gives you some idea but it would be pretty difficult to estimate a forecast for various intermediate points from that map. Let's just say it seems pretty certain that the coast from Dublin around to about Wexford should get a pasting, and as winds turn more towards NE (above the surface) there's a much better chance of streamers getting past the hills and into the southeast counties in general, whether they will contain much snow at that point???

This thing about the NW surface winds is consistent with streamer or squall band dynamics, quite often the wind near the surface is an inflow wind to replace the cold air going rapidly upwards in the squall band over the warmer waters. That air has to be replaced from nearby cold, dry air and so it's fairly frequent to find that streamers (squalls) have winds at right angles to the forward direction of the band itself. In Ontario, I've seen winds go around almost opposite to squall direction at times, like a light east wind underneath a fast-moving squall from a westerly direction.

Near the centre line of a streamer (squall) you will find the winds moving more forward with the band and this is where blowing snow becomes a problem. On the margins, it's more of a swirling effect. This is why, sometimes, when you drive into a squall band you have a totally directionless feeling as the snow seems to be coming at you from all sides -- it probably is in fact. And something else that you'll probably have observed in past events, streamers can have very marked boundaries giving snowfalls of 10 cm or more in one location, and almost zero a mile or two away. The more "unidirectional" the winds in a vertical profile, the more this effect is likely to be seen. We've just had a situation over here with heavy squalls coming off southern Lake Huron where one town saw 80 cms of snow in a short period, and a few miles to the east, almost nothing recorded, same to the west. I'm not expecting anything that dramatic here, for one thing, when streamers have to get past hills and coastal variations, they tend to spread out and become more "diffuse" which reduces the amounts at any one location but expands the total areal coverage.

Checking out now for a supper break here, back around 0300h to see what actually happens.

well it's definatly going to snow in most parts of dublin this morning thats for sure but navan looks like escaping it. but anything could happen. a tough one to predict.

Um. If I input Kilkenny it zooms in to the South East focusing on the Travelodge Hotel Waterford.

Must just be a one off.

wish that system over souther england was over Ireland we would all get a pasting - she is rotating nicely.

joes girls

not a star to be seen now, the sky looks full of snow:):):)

rain today has taken the zoom feature off, presumably because that many people in Britain were using it with the curent situation over there that it was slowing the site down... it says something like that on raintoday... and it makes sense as a lot of people said it was slow yesterday.
