    More to follow as it's still a little early but prepare for some of those early seeds to fail.;)

    Would we not need uppers of at least -10c at this time of year for snow to fall at low levels, doubt -7/-8c would be quite cold enough.

    Different models are showing slight variances with regards to precipitation. Some are showing very heavy snowfall in certain areas during night hours. If this were to happen in any area, I think it would be so strange to have snow on trees that are now almost/fully in full leaf. I'd imagine the branches would be weighed down very easily.

    Some of the trees & plants could get very brown & stunted from this cold spell.
    Something like that happened about 5 years ago in Galway due to a storm in May. 
    It ended up blowing sea salt far inland which damaged all the young leaves. We had brown trees for most of the summer as a result. 
    That would probably show up in tree rings as a catastrophic summer!

    The GFS shows the -10c isotherm pushing into Scotland on Tuesday. The lowest Ireland currently has is the -5c isotherm on the GFS.

    The scottish skiing season might get enough snow to reopen so after a dismal year.

    Can we have a ban on frivolous cold snap threads?

    850hPa temp run from the exact same time last year. Scarily similar to the current forecast:

    Haven't time to look at the temps this spell of weather in 2016 brought, but I can't recall this being a notable episode because I can't remember it at all. :o

    April 2015 and 2016's cold snaps at the end of both months were nothing notable.

    All the news headlines including BBC were saying that the April 2016 cold spell was going to be the most significant April cold since April 1981. Meh, not even close.

    I recorded a mean temperature of 5.0c from April 26th-30th 2016 which was -3.3c below my April LTA but personal experience tells me it was nothing exciting and was very forgettable. My minimum temperature for instance was -0.9c on the 27th. My lowest maximum temperature was 8.7c on the 28th. But hey, I don't speak for the whole country so here's some Ireland statistics.

    This is the IMT (Irish Mean Temperature) for both April 2015 and 2016 during the period 26th-30th. April 2016's cold was colder than April 2015 but they were both fairly close to each other in terms of the IMT. Interestingly, both spells had their lowest IMT on the 27th.
