Increasingly cold this week - frost widespread, risk of snow

darkman2 · 03-12-2011 6:26am #1

Winter is starting on Monday it seems. A cold polar maritime regime is about to take hold and that means frost and ice for inland areas and coastal parts away from an onshore breeze. Meanwhile showers or longer periods of rain may occur from time to time. This should turn increasingly wintry as the week goes on and towards the end of the week a much colder Northerly airflow may take hold. Snow is more and more likely at times as the week goes on although it may turn a small bit milder on Wednesday for a time. Current model projections suggests even colder weather for next weekend. Indeed toward the end of the working week daytime temperatures may struggle to get above freezing so watch out for ice. But that is a good bit off yet. A very cold and wintry week ahead.

More later...

At night, next week, lows of 0 to -6c locally particularly later in the week. By day maxing out at 6c for the first half of the week. Much colder after that. Be lucky to see 4 or 5c as a max temperature. Where snow falls and accumulates you will be struggling above freezing. However a bit of a break Wednesday and Wednesday night. Should be a bit milder then. But very cold overall I think.

Thanks Darkman..... Time to turn off email alerts me thinks - The start of the 200 posts a minute of " Will it snow in X "........ Ill pop in from time to time instead for updates......

Yes BBC are using the Snow word from monday onwards!!

Hells Belle · 03-12-2011 8:46am

From met.ie:

Sunday night: Snow showers over parts of Ulster; clear spells elsewhere and just scattered wintry showers. Lowest temperatures from -1 degrees (Leinster) to +4 degrees (west coast and southwest coast) with a sharp to severe ground frost away from Atlantic coasts. Monday: Good sunny spells; scattered rain, hail or sleet showers in parts of the west and north. A cold day with highest temperatures on Monday only 3 to 7 degrees in fresh to strong westerly winds. Another cold night Monday night with air minima away from Atlantic coasts again down to zero or -1 degrees with a sharp to severe ground frost. Some wintry showers possible in parts of the northwest but most areas dry. Tuesday and Wednesday: Tuesday will start cold and mostly dry with sunny spells. It will cloud over with rain moving in from the Atlantic bringing temperatures gradually up to 8 to 11 degrees and staying around these values for Wednesday with cloudy weather and further outbreaks of rain. Clearer, colder weather developing later. Thursday and Friday: Cold with typical daytime temperatures 5 to 7 degrees and some night frosts. Some sunny intervals but some wintry showers also and there is a possibility of a spell snow on Friday

All aboard :pac:

Very interesting to see Met Eireann come out and say a "Spell Snow" next Friday. Whoever was writing the update must have been all excited and go it the wrong way round. All the same very unusual for them not to sit on the fence and say Wintry Showers. Just reading MTs latest update and no mention of any "Spell Snow" from him for Friday.

The lovely Eveyln cusack ramper fantastico was on duty this morning.

Derfil · 03-12-2011 11:23am

Wonderful news first thing on a Saturday morning

Bishop_Donal · 03-12-2011 11:25am

Don't think we exactly need to start stocking up on the tinned food just yet! Will be interesting to see how it develops, but I'm guessing you'll be travelling to Errigal for this particular snow event.

It's just the commencement of the downward temperature ratchet and reversal of airflow as we prepare for the January whiteout. I'd say temperatures will never reach higher than -5 degrees at any stage of January at all this year, and that we'll have 47 feet of snow with some drifting also:D

JanuarySnowstor · 03-12-2011 11:33am

As I mentioned last night snow is quite likely Sunday night for a large swathe of the country
Yes Friday looks to be even better, but why look that far out when we could see some white stuff in a day's time

:eek:

How do you see this? The "Snow Gods" haven't made this prediction

WHile I'd love nothing better, I can't see this happening based on the forecasts and info from M.T.C. and Su C.

What do you mean by "large swathe"? Do you mean above a certain altitude and possibly the most northern parts of the country?

Wishful thinking me thinks, personally I don't see it happening.

Lucreto · 03-12-2011 12:11pm

Well it feels like winter hit us like a ton of bricks.

I am hoping for some snow even if it is the horrible wet stuff not the nice stuff we got last year.

Su Campu · 03-12-2011 1:06pm

I think it may just be too breezy throughout for widespread frost in many areas, but there will be some ground frost in sheltered areas.

I don't see this myself. Precip looks very minimal to non-existant apart from the northwest tomorrow night.

Maybe you can be more specific than a large swathe. Looks like a light dusting of snow that quickly melts at best in the north/northwest at low levels. You will have bragging rights if there's serious snow across 'large swathes' of the country come Monday morning.

eyesquirm · 03-12-2011 2:50pm

Just my humble opinion, but I can't help but think that come Monday, "large swathes" of the country will be disappointed to see the rain falling.....

snaps · 03-12-2011 3:00pm

Hasnt been a bad day, sunny, breezy & mildish! But now there's a chill setting in. Wind changing direction and temp dropping was 12c an hour ago but now 8c and slowly dropping.

More than likely you'll see nothing falling, away from the north there probably won't be any precipitation. Have a look at the radar right now to see what it'll probably look like with the showers dying out as they go further inland

I'll be travelling through the hills on Monday morning so should have a good idea of the height of the lying snow level (assuming its not sea level). Looking promising for me in Letterkenny either way though!

force eleven · 03-12-2011 3:14pm

At least it is more seasonal than the dross we've had over the past few weeks. Certainly getting colder and beyond 7 days who knows? Perhaps a signal of even colder weather on the horizon, but we may have to wait until later in the month before we see it.

stevielenihan · 03-12-2011 3:24pm

Is Snow likely for the week ahead?

It is due to intensify though as the weekend goes on and more precip over more of the country

Hal1 · 03-12-2011 3:26pm

Looks how far south that 528 dam thickness is :eek:. If it comes to pass we'll have a similar snowfall to last winters.

Read the thread!

Su Campu · 03-12-2011 3:28pm

We really need 522 dam for snow to all levels at this time of the year, but a more important thickness is the 850-1000, which needs to be below 129 dam.

I love watching that happen.

It was like last December when it warmed up for a few days and watching the temperature drop from 6c to -3c.

Where can you see charts for that one Su ?

Weatheronline.co.uk, they're available for the GFS and NAE.

JanuarySnowstor · 03-12-2011 4:06pm

Ok folks, plenty on here have questioned why I think we will get a widespread snow event Sunday night / Monday
To look at the current charts you would be right BUT everyone is ignoring the deep cold over Iceland and more particularly Greenland.
My belief is that this air is Polar Low productive and that there's a signifncant chance of a small Polar low forming on Sunday night.

Anyway, the 12's will be out soon and I fully expect upgrades!

If you are correct i will take my hat off to you but at the moment i think your over eagerness of seeing what you want to happen is clouding your mind to what is only going to be a minor flirt with winter.:)

people on here always mention the possibility of polar low but it never comes out to be right!, I heard it too many times and it never happened

They start rolling out at 15:30 and usually take a little under 90 minutes to complete.

The updated models role out every 6 hours; at 03:30, 09:30, 15:30 and 21:30 - All times in UTC/GMT.

jimmy.d · 03-12-2011 4:30pm

So we will know around 1700. Look forward to it.

*Begins snow dance*

highdef · 03-12-2011 4:52pm

You should know by about 16:30. If you look at the GFS charts on net weather now, you will see that the first few updated charts are already in. At some point, you will get blanks as the information has not yet been updated. If you check again a few minutes later, you will see the charts but the one after will not yet be available. And so on.

Not sure if that makes sense!
