SNOWWATCH

Fax chart for midnight showing a trough. On high ground away from the coast that should be wintry.

Snow risk forecast maps showing snow for this evening in the east??

GEFS likewise showing the highest chance of snow in the east during the rush hour this evening. Probably little more than a short flurry, but no doubt enough to cause serious disruption.

That is showing 50-80% probability of precipitation falling as snow above 300m in that area.

One thing to note is the wind speeds. M.E. are going for quite strong winds this evening. So any showers that do make (snow or rain) will be moving fast and therefore won't get a chance to leave much as they pass.

Cold air arriving now, dew point down to -2 at Donegal airport

FWVT

There is quite a bit of discrepancy between the models regarding snow parameters this evening and tomorrow. I would be looking for the following as first guess for snow to all levels:

850-100 hPa thickness: 129.0 dam or lower
850 theta-e: 10 °C or lower
850 theta-w: 1 °C or lower
500-1000 thickness: 518 dam or lower

The Euro4 and Hirlam meet these thresholds but the GFS hi-res does not, so it remains to be seen what effect the north Atlantic has on the airmass to our north. I would expect some flurries at low level inland during the night hours.

seamus

Most of the 6Z models downgrading the risk of snow for the east this afternoon/evening. If there's any at all, it'll only be above 200m.

Just had a very light and short snow shower in Strabane. 😄

Something is falling in Donegal town now. Not snow and not hail - kind of in between....

Same in leopardstown

2 degrees at knock airport now, dewpoint 0. Once the sun dissappears this evening, there should be snow at knock depending on track of the showers of course

Snowed in navan, meath just now

Short lasting RAIN in Galway City.

Snow to Sleet here in Naul village, north Co. Dublin.
Very cold out there, no temp gauge though, sorry.

Some wet snow on cars in glencullen. Probably gone by now though.

Some showers on the way to west clare now coming from the north west, temp is dropping rapidly (now 4.9c) and dewpoint is around -2c I think, hopefully some sleet.

manutd

Snow in Cavan town the last 10 mins

Gonzo

showers dying out fast now everywhere.

redsteveireland

Something closely resembling icy rain here.

I saw on Facebook a bit earlier on about very, very light snow in Ranelagh. In Clondalkin, however, it just got very dark, and lashed for a short time.

Nope, just very icy rain associated with strong winds. Temp now down to 4.2c once the showers departed. Quite low for the coast.
