Greenland Express: Snow showers possible from Monday night

Kermit.de.frog · 15-01-2018 6:28pm

The showers will begin transitioning to snow more broadly in the northwest over the next few hours. The snow level is progressively falling. Knock reporting Sleet at 5 pm.

Probably snow beginning to settle before midnight in the northwest and north.

Reckon it will be after midnight before snowfall becomes more widespread in showers and begins falling to lower levels elsewhere.

Interesting night ahead.

Those high res GFS charts will just cause you disappointment.

e.g. compare these two high res charts for same time period

Is it just a missprint saying the Valid time is Tuesday 23.00? Surely it should say today 23.00? Sorry if it's a stupid question!!

I'm based outside of Derry, have had sleet/rain showers since midday, progressively getting colder as the day goes. Currently around 3c here. Now... back to watching my lamppost :P

Latest Euro4 just out is still looking ok

Fixed in met page now..had just sent an email warning of snow tomorrow then saw this and thought I had made a mistake! Phew.

Now here's a weather forecast you don't see too often, Derry TAF for later:

Thundergraupel!

If I didn't have to work tomorrow I'd stay up very late and watch lampposts.

The irony being that if it does snow, I probably won't be able to get to work in my rear-wheel drive car.

A very unfortunate paradox

Buffalobill29 · 15-01-2018 7:46pm

How much snow does it look like North Offaly will get over tonight and tomorrow and North Kildare as well?

mountainy man · 15-01-2018 7:49pm

The last couple of showers are a mix of sleet and wet snow here in the hills of s e Sligo.

q85dw7osi4lebg · 15-01-2018 8:04pm

The lamp post watching begins when Mountainy Man chimes in!

Gaoth Laidir · 15-01-2018 8:06pm

Ballypatrick Forest on the Antrim coast reported 16 cm of lying snow this morning, but that's obviously an instrumental error. Maybe it was getting a bit ahead of itself...:pac:

Knock Airport, recent snow, and so it begins

No just around the Strabane area..you're going to miss out according to the ECM.

Gaoth Laidir · 15-01-2018 8:49pm

The GFS, at just 6 hours out, is already several degrees too low on dewpoint than actual 18Z observations and all other models, including the EURO4. Malin Head, for example, had a dewpoint of +1.8 °C, whereas the GFS had it at around -1 °C. It had widespread snow throughout western Scotland by now, but it's still raining.

Caveat emptor...

Actual observed dewpoints.

Violent squally shower passing through here now, may have been a flash in the distance, wind was so noisy I wouldn't hear a rumble anyway.

In East Galway

I always use the full site on the mobile so I forget that you don't see locations on the touch site.

Yes quite a squally shower afew mintues ago in Galway...looking at the satellite images they are only getting going with much bigger showers on the way...they will be quite lively if the first showers are anything to go by...
