Possible dusting of snow for east/northeast tonight?

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!



Dew-point 3am



Dew-point 6am

: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

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.
