    Nice snow showers here in Aberdeen yesterday evening. A very icy day today. Very little thaw. I don't know how the snow seems to hang on here much better than home with the same temperatures.

    The Hirlam has snowmageddon for much of the south and midlands tomorrow, but again I think it is showing false cold (theta-e and theta-w). With soil temperatures falling no lower than around 6 °C tonight and dewpoints remaining above zero the surface cold layer will not get cold or deep enough to support low-level snow in this scenario. Higher ground and mountains will get a pasting, however.

    This is twice in as many weeks that I've noticed the Hirlam being too cold.

    Yep, just as I thought, the 18Z run has no mention of snow, except for the Wicklow mountains.

    Latest EC going for snow inland south Leinster.

    Deem it unlikely though, although if there is some really heavy precip there could be some evaporative cooling and there is a cold undercut. Certainly something to watch above 300m

    That would really be heavy snow if it happened.

    EC is still bullish for snow across inland south Leinster/ wicklow mtns today.

    Any reports from the Roundwood area? Seems far too mild here.

    I can't see that happening at all. The 12Z hirlam yesterday hinted at something similar bit snapped right out of it since. Forecast soundings show that any evaporative cooling potential will still be above zero through a deep surface layer so that would produce cold rain, except on mountains. Dewpoints are 3-6 °C throughout that area now and will only get higher. There might be some brief backedge snow on hills this evening.

    Soil temperatures are high and I think the ECM and hirlam have been struggling with that. The surface layer could never get cold or deep enough overnight.

    Yea, I certainly wouldn't be following that guidance blindly, although the fold air does undercut this afternoon and 850 0C isotherm backs east. Likely to be some sleet.. wet snow if precips stays heavy enough. Would not expect low level accumulations, but these things can be tricky. Current conditions can often have limited relevance if the cold undercuts and the precip is really intense.

    Evaporative cooling should lower the snow line down to around 300/400 metres this afternoon I reckon. Precipitation looks to be very intense with spot flooding a possibility. In the city a lot of cold rain with sleet at best.

    It's very cold here in east Clare.
    The temperature has dropped significantly...

    Current DP in Ashford, Wicklow is 6.2C..... I really can't see this turning to snow other than on the highest peaks. If I get a chance to take a spin up the gap (circa 500m) later, I will report back later.

    I'd wait until afternoon. Any possible snow (to high ground) would be more back edge stuff, as the rain band starts to move east and colder air from the NE is dragged in behind.
