    today was a bit showery, however they were very light. Looking forward to several days, almost a week of dry and settled conditions. We have been wishing for some proper dryness for months now and this could be the first proper high pressure we've had since July?

    Started college in sept, we had a week or two of warm dry weather then but nothing really since in cork. Its been very wet either drizzle or heavy rain. A few dry days but definitely a lot of wet days even if the amounts were low.

    Looking forward to this high pressure spell

    Correct, here's a chart showing that high giving the warm and dry weather on 13th September and lasted to later on the 20th with the exception of some weak fronts giving cloudier and cooler conditions on the 15th/16th.

    Late October had a ridge collapsing from the northwest on the 27th and into Europe by 30th. Early December was similar. Pressure was relatively high for late December too but its centre was in central Europe away from us so was only temporary with a lot of southwesterly winds giving cloud and drizzle.

    https://www.severe-weather.eu/mcd/extremely-high-surface-pressure-1050mbar-mk/

    An *EXTREMELY HIGH* surface pressure develops over Europe through Sunday and Monday – 1048-1050 mbar will be possible in some areas!
    A very strong upper-level ridging develops over eastern parts of North Atlantic, expanding into western and central Europe. As a result, an associated surface high-pressure system develops and brings *extremely* high surface pressure. A large part of Europe will experience 1030-1045 mbar mean sea-level pressure, while some regions could even see close to 1050 mbar!
    Such values of surface pressure are VERY extreme for some parts of Europe. Therefore, we should not be surprised to see some location coming very near their all-time high-pressure records.

    Yeah what does very high pressure actually mean in real terms - I know we will get dry, cold and calm but are there risks with 1050mbar?

    The boiling point of water is ~101°C at 1050mbar so be careful, your tea might be slightly hotter than usual! Other than that no significant real world effects other than dry sunny weather, it's just interesting from a meteorological point of view.

    Severe Weather is just another clickbait site with what appear to be striking headlines. It's a quiet period weatherwise so I suppose they need to take what they can get.

    -1.8c in North Kildare. Following a fairly hefty shower not long before sunset, the local roads are now treacherous.

    tonight could possibly be the coldest night of the winter so far which wouldn't be difficult. currently 1C here.


  • Registered Users, Registered Users 2 Posts: 529 ✭✭✭Goldfinch8


    Good to get a chance to see Orion striding his way across the winter sky tonight followed by his sparkling companion Sirius. Hope the High pressure gives us a few more nights like this. Not enough of them so far this winter in this part of the world.


  • Registered Users Posts: 4,693 ✭✭✭SleetAndSnow


    Nice to see some frost on the cars again in cork city, makes it feel a bit more seasonal at least.

    Yes indeed. When we get a chance to see them the constellations at this time of the year are truly spectacular.

    Not seeing stars on a January night used to be more unusual in the 80's:o First night you can put the cans outside instead of in the fridge in ages.

    I know. When the next BFTE or really cold spell happens we are all going to perish!

    Midnight runs have backed away from the dizzying highs a little but still potential for the extreme SE to get a 1048 hPa reading early Monday morning:

    Last time pressure got this high in January seems to be in 2000, when 1047.3 hPa was recorded in Valentia at 9am on the 16th (I haven't looked at other station data and data is from Met Eireann)

    I like the way the headline almost suggested we're all gonna die. High pressure is safe pressure kids.

    A lovely clear sunrise in central Mayo here this morning and a good old crunchy frost underfoot. Some thin and wispy high cloud has filtered in from the west over the past couple of hours but it has done nothing to take away from a cracking January morning so far. Still a nice bright day.

    Lovely morning in Galway. Delighted to get a bit of cold and frost. Sun shining too.


  • Registered Users, Registered Users 2 Posts: 1,577 ✭✭✭Billcarson


    My first air frost this morning of the meteorological winter. A day later then last winter. Shows how bad this winter and last winter have been for cold.


  • Closed Accounts Posts: 4,431 ✭✭✭Mortelaro


    Despite the cold start,theres a lovely feeling of warmth in that sun out there at the moment


  • Registered Users Posts: 2,023 ✭✭✭Donegal Storm


    Raining in Letterkenny :rolleyes:

    Lots of hail downpours yesterday evening and last night, calmer today but so much for a dry weekend...

    got to -1 here in Dunshaughlin last night, the coldest night of the year so far.

    Today could well be the coldest day of the winter with temperatures of only 4 or 5C in most parts. Another very cold night tonight. Becoming slightly milder from tomorrow with temperatures around 6 or 7C and rising slightly further next week as the westerlies come back into play once the high pressure loses it's influence later in the week. Becoming very mild again towards next weekend.

    Certainly one of my favourite days of the winter so far. A cool, crisp and pleasant dry day with ice already forming on the car as soon as the sun went down. This spell of high pressure is a nice reprieve from the Atlantic frontal systems.
