850hPa temps around now are about -5,-6 but are due to drop to -8 for a time over the next few days, if we could squeeze a -9 maybe some coastal parts of Dublin could catch some snow...

GFS charts

around now



tomorrow night

Just be aware that the 850hPa level is now 300 metres higher.

And yes I am surprise at the cold. I did not realise we would be under at least -6c hPa for the next couple of days.

[Gonzo]

after midday tomorrow we do get colder uppers for the rest of the week, generally -6 to -8. The -10 just about tips into County Donegal on Thursday night into Friday morning.



-9 across the whole country early on Friday. Sadly it looks mostly dry through most of this period.

my part of Dublin bottoms out at -8.5c on that GFS run at Tuesday noon, with a dew point of -0.4c. of course it looks dry though! Friday brings -9.6c uppers and a dew point in the -3c/-4c region but also some snow for the north, west and east.

If that front on Thursday can fall of snow and the high pressure orientates to keep us on cold side, we could have some very cold nights at the end of the week if snow on the ground.

So much for the -10c uppers. They have no been replaced by a warm core. Typical

the GFS still has countrywide sub -9c uppers and the chance of snow showers for some on Friday, hopefully it's correct.

Getting increasingly cold as we move through the week with sharp to severe frosts right up to Sat morning. Models all showing wintry precipitation later Weds into Thurs with a slow moving weakening front moving down from the NW / N. Freezing looks set to move in quickly Weds evening and 850 hPa temps look decent for sleet and snow, maybe freezing rain also, what falls would more than likely be falling onto freezing ground and would no doubt lead to very tricky driving / walking conditions on Thurs morning. To me it looks like the top third of the country with the most snow, especially higher ground but looks like lower elevations will see snow also but in general it looks light. All depends how much precipitation the front holds as it moves down the country, currently looks like sleet or a dusting of snow is possible down along the country, amounts atm look light, would think a fair chance of light snow flurries in places.

Some very cold air showing up on the models Fri and Sat especially down along the E and SE and models showing that snow showers could occur close to or moving in over the coastline , the SE looks like it could get snow showers Fri night /Sat morning. Wicklow Mts should have a good coating by Sat morning.

That looks fabulous for me! Unfortunately it’s high pressure.

Excellent Meteorite as always. Plenty calling this mini cold spell over before it has begun.
Just the prelude before the main event later in the month I hope. Time to look at the oil tank levels...

The ECM run tonight has more dark blues over us in its first 5 days than we often have in a winter!

Not bad at all.

[nacho libre]

I prefer the colour Purple, but dark blue isn't a bad compromise. Hopefully there will be snow a bit more widely about on Thursday and Friday!

[Gonzo]

a chance of some transitional frontal snow on Thursday from the leading edge of that band of precipitation. There will be a mild sector involved with it tho, dew points rise just above 0 as the band crosses the country and falls again after it clears. Some places could see some flakes, but the chances are that it will turn to rain with the exception of high ground as the temperatures, uppers and dew points rise briefly.

[Artane2002]

that chart shows a chance of freezing rain for some, could be interesting to watch.
