Spotted that too, sky went extremely dark for 10-15 mins.
It was trying really hard to snow all the way round the M50 just now. Lashing sleet really heavily, flakes both visible and audible, unusual combination! Sadly just a degree or slightly more too warm.
I'd say Dublin Mountains above 300m or so are a winter wonderland again.
Bugger all happening at 150
1st rain shower of the day here near Arklow just now
Horrible, awful, brutal night here! Worst of the winter so far. Just 2 C and 6 hours of constant torrential rain driven by a gale force Northerly wind.
