Cold Spell Discussion (Ireland): Cold/Frosty/Icy with Snow for some

Enough model guidance this morning to open a warning/chat thread for likely cold spell which could arrive with a bang as early as tomorrow.

Initial guidance is showing the chance for snow to fall in some areas as early as 6am Friday, however there remains uncertainty over where the border between rain and snow will be and with timing.

Overnight Thursday heavy rain will push from the west to affect most areas. During Friday morning cold air will begin to be pushed in to the northeast and this will continue through Friday slowly turning the rain to snow from the northeast. The extend southwest of the transition remains uncertain. Areas right on eastern coastal fringes will take a little longer for a full transition to snow due to sea influence.

There is potential for significant accumulations of snow in places through Friday evening and overnight.

Through Friday night the cold air will steadily track over much of the country, particularly more northern parts with periods of snow coming onto the east coast at times.

Saturday will see Ireland in a bitter east flow with snow showers at times on the east coast. Extremely icy overnight Saturday with minima towards -6c.

Late Sunday frontal features from the southwest will bring further risk of snow to many areas, but track and detail will be best kept for later.


So initial risk tomorrow, with the NAE map for 6pm Friday used as rough guidance (but expect some change to snow-line between now and T0)

Just a word on the temps forecast for late Sat night / early Sunday morning. I would not be surprised if temps of -10 were recorded in inland areas with snow cover. If I had to pick an area most at risk of snow cover and extreme low temps, County Monaghan would be a good bet.

To kick things off, at least Evelyn is on duty this morning.

Just caught the end of her sea area forecast on Radio 1 and she said ' tune in at 5 to 8...looks like some very wintry weather on the way'.

Certainly when ME start talking about sub zero daytime maxes later next week, you start to sit up. But see how quickly they changed from yesterday morning. FI is 48-72 hours.

It is, but, in theory the front should be stalled and/or move back west or fizzle out.

Radio forecast sounds nice!! and she at least stresses uncertainty unlike Gerry- also says high possibility of severe weather.

Possible disruptive Snow tomorrow!

Snow showers in the east on Saturday...
