    Very nice 6z. The high is centred to the east of us and might just be the difference between that dreadful anticyclonic gloom and clear frosty weather as drier air filters in from the east.

    very interesting indeed big changes comparied to earlier runs


  • Registered Users, Registered Users 2 Posts: 17,907 ✭✭✭✭nacho libre


    a trend or a wobble, the ensembles were hinting at this while the op wasn't. sometimes the gfs is good at picking up on a new evolution before the other models. although it is hard seeing the high moving north like this with the jet moving back north.

    this still looks good to me.

    Signs of an easterly later this month:



  • Registered Users, Registered Users 2 Posts: 6,346 ✭✭✭Elmer Blooker


    no major changes this morning, who knows what will be happen, it could be a mild anti-cyclonic gloomy high or a cold foggy high where fog could persist all day. You know Valentine's Day is coming when you see a high shaped like this!!

    Some of the GEFS perbs look good.

    Will be interesting to see how high the HP will move up.

    In terms of GFS v ECM / High Res Model's handling of tonight's low, I would point out that this morning's minor event has been predicted best by GFS. It predicted snow in Kerry & West Cork (but not Cork city) and that's spot on. As best I recall the others saw no precipitation making landfall (or nothing east of about Dingle anyway).

    ECM showed the light precip that's over the southwest at the moment.

    Interesting chart on the earlier 12Z run at +300 hrs as regards the contrast in 850 hpa temperatures across Ireland. 0 in the SW and -10 in the NE.

    I wonder if history would be kind enough to repeat itself...?

    Outlook chart for Feb 14th

    Analysis for Feb 14th 1903:

    Rrea00119030214.gif

    Broadly similar pattern, but in 1903, the weather became more disturbed after the the high collapsed, peaking on Feb 27th when the 'Ulysess storm' roared in, which was possibly one of the worst storms of the 20th century to rage through Ireland.

    Brief report on that particular storm here:

    1891 After a very mild and dry February, March must have come as bit of a shock. The winds turned to the north on the 7th, and then there was much snow in the south. This time saw the great west country blizzard: one of the most severe snowstorms of the century on the 9-13th, perhaps one of the most severe snowstorms ever. The southwest and Kent were particularly badly affected. 220 people died as many ships were lost at sea. Apparently sheep were blown off Devon cliffs in their thousands and also lost at sea. Snow drifts were reported 20' deep, created by the heavy snow combining with a NE gale.
    I presume there were blizzards in Ireland too by the look of that chart?

    It probably got downgraded ^^^^^^^

    there was probably a warm sector over Ireland and it just rained!

    Like the Spanish Inquisition no body was expecting this!
    The chart even looks like this

    Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.
