Wintry spell with Snow and Ice warnings week of 20-3-17

Mountainsandh

I got better quality pics for the snow bunnies.
The size of the flakes is ridiculous !
There's an obligatory impressive car bonnet one, because you'd have to have it.

These are the last ones, promise. For tonight. If I have 3 feets of snow outside tomorrow I might just take another one

edit : the pics are not from February, they're from now. We didn't get snow in Feb, or at all this winter for that matter. Not like that anyway.

Increasing sleet in the precip now 2.6c

March11

Just woke there, velux is covered full of snow again. Between Youghal and Dungarvan, we are up high though.

north Kildare, near Enfield. Some snow mixing in with the moderate rain at times. Temp now down to 2.4c.

Rain now turning to sleet as well in Hollywood village, bang on at 200asl,about a degree away from a massive snow event,a pity

I would be very optimistic that you will get a lot of snow there tonight. The hills and mountains are literally beside the village. You're in as good a spot as you could hope for tonight.

Turning to Wet Snow in Kildare now

Periscal

I wish but just don't have that feeling tonight, according to Yr.no, EURO4 and GFS the most likely chance would be between now and 6AM, this is more like a wasted synoptics, looking at how close we are to snow and how much would have accumulated over next 24 hours,we had a lot of wrong marginal events this winter,wish we could live at elevations between 500 and 700m, somewhere up the Wicklow Gap, I mean like a proper village rather than an isolated cottage

Cashel in Tipp is 0.6c: https://www.wunderground.com/personal-weather-station/dashboard?ID=ICOTIPPE2

Surely snowing there as the radar is lively enough across Tipp.

I just shook off the massive marginal event from DC to NYC last week now this, similar sort of thermal profiles aloft, so could see roughly similar results, widely varying snowfall-sleet-rain portions depending on how small ripples of energy play out circulating around the Irish Sea low. There's a weak "pseudo-front" showing up aligned NNW-SSE through central counties, west of that mixing may occur faster. This has developed because clear conditions in parts of west Ulster are allowing subzero dew points to enter the western part of the circulation. The harder the mixed precip comes down, the more likely it is to change over because that means it spends less time in the warmest layer which is probably about 5000' up. In the U.S. event, as one example, DCA on the warmer side of Washington DC had 2" snow and considerable sleet, some rain, while IAD on the colder side had 6" snow and mostly sleet otherwise with just small amounts of rain.

This was the event last Monday-Tuesday on the east coast of the U.S., there were also very tight gradients between sleet and snow in the NYC metro area and in Boston into SE Mass and Rhode Island.

This warmer layer aloft may mean that snowfall with elevation rules will be partly verified but only between 150m and 500m, perhaps no increase at highest elevations.

Just think though, if this all came down as snow there would be 20-30 cms.

Interesting to see the differences across inland areas... https://www.wunderground.com/wundermap

Now turning to snow,big flakes about 80% snow,this could have been epic perhaps a month ago,now way too wet,at least no rush hours manic at 7AM, elevation and local topography is so important, was home last week in Slovakia,hometown at 305asl,was 6-7 degree warmer then some villages north of it at 800asl, surrounded by hills from all directions,kind of bath thub shaped valley,local b&b owner said its not uncommon to heat in July for few hours! Cold air firmly trapped in the valley,proper frost hollow every house stashed with firewood outside in sheds, now that is my cup of tea,heh

1.5c and it still hasn't changed over fully yet but it's getting there

Danno

Sleet 2.8c / 1.6cDP.

pad199207

Has made the change now. Lovely snow but still a bit wet 1.1c

I second that Danno...Time for the leaba though:)

7 miles north east of Kilkenny city on the hills, snowing.
Temperature 1.2C and falling
Dewpoint 0.6C

pad199207

Veluxes have a coating now 0.9c

pad199207

Stick to cars and grass now 0.8c

Danno

Radar seems to show it pepping up across Leinster. 2.5c and 1.3c DP. Colder air starting to dig in. Wind has gone NE.

Same here, temerature falling fast with the snow.
0.9C.

Looks like we could be on course for the biggest covering of snow in a while.

highdef

North Kildare, near Enfield. Full on moderate snow, bordering on heavy. Dinner plate flakes. Sticking to rooves, cars and grass.... And telephone wires.

RobertKK

Met Eireann spot on with the snow, as for accumulations we will have to see how they did with their predictions.

Will agree when it starts to snow proper here and accumulate! :P

Temps still dropping fast, around 0.1c every 5 minutes and dewpoint going the same. Currently 2.2c and 1.0cDP - so not far to go!

pad199207

Lovely snow now. No wettyness to it

You aren't that far away really in Durrow.
0.4C with a DP of -0.2C.

Signs of the snow starting to stick to concrete surfaces.

Danno

Wet snow here now. 1.7c and 0.5cDP. Probably be sticking in around 20mins giving the rate of precip and associated temp drop.

RobertKK

Went out to see if my cat was around as he was not fed, no sign of him, but the snow is heavy and the yard is white in large sections.

Maybe several inches of snow???

RobertKK

Was about to head to bed, and heard my cat, so fed him, all surfaces are now covered in snow, the daffodils don't look to be enjoying it.
