How many miles off shore are these?

The M6 record is particularly interesting. Wouldnt be surprised if it occurred with heavy showers as its located far enough west to get showers off a deep easterly.

Probably the last snow depth chart of this event. Still had 13 cm in Tallaght today, but the other stations are in rapid decline. Casement has stopped reporting depths in the past few hours.

Did Shannon break it's 6cm record? Well that's the highest it had in the last 50 60 years according to the Met eireann image posted.

No it didn't, surpringly the area around Shannon didn't get that much snow while most of the rest of Clare got a sizeable amount. For example driving on Sunday from West Clare to Ennis, there was snow cover in every field, yet from Ennis to Limerick there was very little to none.

That's Friday's ECM 0z.

Kermit.de.frog

Todays ECM to come, we'll see if there is any progress but the UKMO is sharp enough. GFS is near miss territory.



All to play for. No sign of Spring yet.

Kermit.de.frog

ECM @120 hrs - gonna be close

JCX BXC

Lots of flip flopping with the GFS, the 12Z has the cold staying over Russia, the 06Z had it over us, the 18Z yesterday had the cold staying Russia, the 12Z had it over us.

In essence, don't take the GFS with any confidence.

ECM @ 144, could be a near miss but the potential is definitely there for some more disruptive weather. I still consider it less likely than something more benign.

Yes it might be best to close this thread for now and use the FI Thread https://www.boards.ie/vbulletin/showthread.php?t=2057847461

or

Spring 2018: General discussion

https://www.boards.ie/vbulletin/showthread.php?t=2057846555

If some severe weather does materialize a thread might be opened for that if needs be.
