Turning cold with Frost/ Ice and some Snow (Thursday night/ Friday/ Saturday)

Winds will continue to be strong tonight particularly in the northeast.

As the evening progresses it will turn notably colder from the northwest with temperatures tumbling to 0-3c overnight.

Most notably dew points will turn lower and remain at 0c or below from around 6pm this evening.

Wintry showers will affect the north and west increasingly turning to snow inland of the coast and on hills.

Towards dawn a organised areas of precipitation will push into the north associated with a shortwave type feature illustrated here to our northwest.



This has the potential to bring more organised snow showers to the northern half of the country towards from early morning to early afternoon.

It is likely some accumulations will take place especially inland and over 100m.

We will use this thread to chat about the impending short cold snap.

No good at reading these charts, no matter how detailed.
If this materialises, will the showers affect the North, NW, or more countrywide? Or is it too soon to say?

The temperature has actually risen again here after consistently dropping all morning, back up to 7.4C again having been at 6.2C an hour ago. Dew point continuing to drop though with RH at only 69%, currently at 2C so it should go below zero at some stage this evening assuming humidity doesn't rise too much

A few squally hail showers but mostly dry so far

Won't be online again until at least 7pm so hopefully things will start to change by then!

Edit: Again just as I post something happens! Very heavy shower of sleet and hail just there, first proper wintry shower and dew point down to 1.2C, not too far to go now!

I take it this dew point is somehow related to the chance of snow, yes?

I think the dew point has to be at 0C or below for snow, but there's other factors involved... there always is!
