COLD SPELL Jan 28th Onwards: Wintry Showers/Frosty, Some Snow Accumulations

RED L4 0TH · 30-01-2015 5:30pm

According to the 12Z GFS, this appears to be the northernmost reach of precipitation for Monday before it pulls away to the south again.

Precipitation doesn't appear to be as widespread for Tuesday (intensity wise) compared to the 6Z run.

That low has been going up all over the place from run to run, someone's going to get lucky

I have to say that January flew by with all the cold weather and snow excitement

And I have to agree with the poster above - Kermit is the forecaster on form at the moment.

Who is Niman on the wrong thread as a matter of interest?

I think I'm not the type to get excited about fairly normal weather conditions, so I'll exit stage left and let you lot continue.

Cheers:D

definitely a few interesting days ahead,we are badly due an easterly for actual proper snow.i know that charts has that high backing south but the Atlantic is weaking so is the jet stream.still the potential is there

redsteveireland · 30-01-2015 7:00pm

Just heavy sleet here now, terrible wind chill.
Turning to snow now, didn't expect that.

FWVT · 30-01-2015 7:02pm

A few photos taken from the viewing point in Kilakee -Military Road (380 m amsl) a while ago. The snow is hard and icy. Air temperature was 1.0, down in Tallaght was 4.0.

JCX BXC · 30-01-2015 7:02pm

3.5c here with a DP of -2c.
Not too bad here. (West Clare)

JCX BXC · 30-01-2015 7:21pm

Looking at the net weather radar, there is alot of snow in the country this evening. Anyone getting any?

snowstreams · 30-01-2015 7:21pm

Good:P
Theres a nice shower on the way to my house, with a low DP and a temperature near 4c here, I hope I may finally get a flurry.

Just back from a hike up slieve foye county louth. Loads of snow some snow was 4 ft deep in places. Even got to build a snow cave. Class day.

JCX BXC · 30-01-2015 7:32pm

According to Net Weather that just passed less than a km away from me, it was on the verge of turning to snow. With temperatures dropping, I have actually felt like I may get snow for the first time this cold spell.

Met E are forecasting wintry showers tonight.

UPDATE to the OP.

Friday 30th January - Thursday 5th February

Overview

Hi all, an update to the OP.

The cold conditions are set to remain until at least Thursday and even this time frame could yet be extended. Winds will vary north to northwesterly and will be strong for a time tomorrow though may go southeasterly temporarily on Monday. After Tuesday winds go more northeasterly.

Temperatures

Daytime temperatures will remain low throughout generally in low single figures between 0 and 4c but night time temperatures will really tumble.

Tonight temperatures will fall to around -2 c in many areas and this brings with it frost and ice for untreated roads. Tomorrow night temperatures will fall further to around -2 or 3 c widely (slightly milder near wind ward coasts). Sunday night will see temperatures as low as -5 or -6 c particularly in the northern half of the country where snow is lying. Again frost and ice will be an additional hazard to any lying snow. Monday night again temperatures sub zero and down to -2 or -3 c generally but under cloudier skies. Again slightly milder on Atlantic coasts. Night time temperatures on current trends will plunge even further midweek and could get as low as -6 or -7 c locally.

Precipitation - Rainfall/snowfall

From tonight most of the expected precipitation will be snow. Over the weekend snow showers will mostly affect Ulster, west Connaught and west Munster settling in places particularly across Ulster. Occasionally some may get lost and end up in north Leinster or the midlands at times so don't be surprised with a random dusting one morning.

This applies to tonight, tomorrow and Sunday.

2 potential snow "events" to watch

On Monday a warm front will attempt to move in off the Atlantic but will stall somewhere near the southwest. This will be coming in to contact with very cold air over the country and the rain will turn to snow away from far southwest coastal areas. There is potential for some heavy snowfall from this that may well be disruptive.

Currently this looks to affect most of Munster and south Connaught. Another affect could be to drag in some light snowfall to eastern counties off the Irish sea.

People in these areas should keep up to date because the exact position of this is a little uncertain still and it may yet affact more than the areas mentioned but the current concensus is it is the southwest that takes the hit here.

MONDAY NIGHT

There is less certainty about Monday night. Currently it looks like an active but shallow trough or small area of developing low pressure will move down from the north. At this stage upper air temperatures and ground temperatures will be very low and it's about as close as we can get to a sure thing for snow in Ireland - on current trends. There is potential for heavy and in places significant snowfall and some disruption.

Again keep up to date with this because it could affect your journey on Tuesday morning.

The orange fonts are the two features that really need to be taken in to account in the coming days. There potentially will be severe weather at times but mostly it should be nice be to look at.

Oscar Bravo · 30-01-2015 7:39pm

Better one here

Schadenfreudia · 30-01-2015 7:47pm

Clear sunny day, now partly cloudy with a light breeze, temp 1.9c. Snow level remained at about 700 feet all day.

Epic snow at knock!!

YanSno · 30-01-2015 7:50pm

there's potential for some convection along the irish sea on monday if track of that low stays the same.temp and dew point are good for those streamers to fall as snow along the east coast

Considering your greatly accurate forecasts over the past few days, I am actually as happy as an 8 year old boy when he sees snow right now. In fact I have only ever witnessed 1 disruptive snow, that was at home here in west clare. This was in 2009, but still not comparable to some parts of the country.

Thanks Kermit for the updates!
