    Well it's possible, a small trough feature moves southwards through England and brushes the northeast and east of Ireland as winds veer just northeast. A much colder airmass lies behind the front and will result in a harsh frost before dawn for many before things settle down through tomorrow Wednesday.

    May be worth a lamp-post watch from around 3-6am!:D

    :DWeathercheck, Great to get a new post with possibility of snow tonight.

    http://www.met.ie/forecasts/

    Met Eireann mention potential for Snow on higher ground tonight in East.:)

    As I am not up to speed on reading all charts. If one was to go on Lamp-post watch in the east, At what lamp post height would one potentially see some white stuff:D

    So the cold front is now moving into the north coast.

    You can see the wind shift here.

    xcweather.co.uk

    & satellite here... http://www.sat24.com/en/gb

    Cold air should catch up with front through the night.

    Note dew-points at or below 0c in southwest Scotland.

    Lets hope the front is surprisingly active as it travels south.

    Even Tiree is reporting a negative dewpoint tonight, a pretty rare occurrence!

    Tiree @ 2220 = 3c/-2c.

    Latest HiRes charts show the intensity dying quickly with little if anything south of border falling excluding higher ground.

    The science of this is above me, apologies in advance.
    I just do not understand why it has not really snowed.

    Temperatures seem to be close to perfect.

    I've often noticed a marked and relatively rapid drying effect prior to snow - that's clearly absent currently; what's different now?

    high res precip forecasts are highly error prone in these situations, nowcasting is more appropriate imo.:)

    Will the Mournes kill it? likely rain now anyway but maybe the cold can catch up with it. + Irish sea showers poss. later.

    3 degrees at the moment, surely the temp won't drop enough?!!

    Its the dew point you want to look for rather than the temp,

    There is a post in here from Su Campu about what you should be looking for

    It can snow as long as the dewpoint is negative.
