The much heralded cold spell has arrived in Ireland bringing the coldest weather since 2010. Last night temperatures sunk to -7 at Mt Dillon and there was snow in Dublin. This only signals day one of a cold spell that is set to last until at least mid December and may last even longer. Over 60 per cent of weather charts show cold weather while 37 per cent show milder scenarios.
Lowest temperature -7c
Most snow 2cm Dublin 16.
Keep tuned for further updates.
There is heavy sleet and snow in the forecast for Ireland this week. There will be very cold Northerly winds as a low pressure system moves down from the Northeast. This will bring some extremely cold weather with temperatures going as low as minus 4 at night with ice and snow by the day. Conditions will be very dangerous on the roads especially after midweek and there are likely to be several weather warnings in place during this time. As we can see from the map the Wintry showers have already arrived in the East. Further updates to follow.
So with the weather cold and unsettled it's time to settle down and watch the world cup. So let's enter the fantasy world Cup on these dark and cold nights. Oops I've signed in. But my username is my own name. How do I change it?
The 1st thing to do is quit the league you have joined and sign out by pressing leave league. Then get another email address you have and create a new username through this one. If you don't have an email address just create a new one it's pretty simple and the username prompt will come up. Once again create a new name but this time your username will be your team name and voila.
Ok back to the weather. Its staying cool and cat. Actually Qatar.
After Ireland had such a dry and fairly warm Summer overall the pattern of weather that Autumn has greeted us with has come as a bit of a shock to the system. There has been rain on most days and no sign at all of any dry weather.
But what is causing all this? Let's go through some of the causes step by step.
1. The sea temperatures.
Over the Summer the sea temperatures had been very warm. However as High Pressure was over or near Ireland at this time the moisture being built up over the warm Oceans was kept well off our shores. When eventually the next Low was to come it would bring quite large rainfall amounts. So if all this rainfall then has fallen why are we still getting more.
2. The pressure
Unfortunately the High that was over us in the Summer has simply migrated slightly East to Europe meaning that Ireland is stuck with a conveyor belt of low pressure systems driving rain to our shores. But how come there's so many lows? I thought there was only one or two low pressure systems at a time.
3. The Dumbbell Effect
What the hell is the dumbell effect I hear you cry. Well it's the name given as the same low pressure system keeps reinvigorating itself as it has nowhere to go due to the high pressure to the East of the UK (where they are also seeing endless rain). So why is the rain so heavy and thundery? Doesn't this just happen in High Summer?
4. "High" temperatures
The High Pressure that lies over Europe is drawing up very warm air as we have seen over parts of Europe in the past week with temperatures of 30.3c in San Sebastian and 35c in Seville and 32c in France. To the West of the High the Low Pressure systems are pushing cooler air but as it meets the drier warmer air convection is occurring causing sparks and very heavy rain. So is there any reason why suddenly from being so quiet that the weather has taken such a nasty turn?
5. The Jet Stream
We often hear Met Eireann and the UK Met Office talk about how the jetstream affects our weather. Well here at weathergossip just think of it this way. If the jet is weak or to our North we tend to get benign weather but an active jet like we have now causes very unsettled weather when it is near or over Ireland. Think Summers 2007 to 2012. Yes yuk. OK so are we stuck with this unsettled weather?
6. Nothing lasts forever...even cold November rain
Well that's what Guns and Roses told us and maybe they had a point. Despite the fact that it seems like the weather is going to be endlessly unsettled due to these "dumbbell lows" it more than likely won't be. So what is going to end this period of unsettled wet weather? Read on
7. How this unsettled weather will likely end
The weather came from the South during most of October Repeated rainfall from the South can last weeks on end pressed up against such a strong high. But there has been a bit of a pattern shift. We have seen a more Southwesterly pattern emerge and this could mean things beginning to settle down around mid November especially in the South and East. There is still likely to be light rain or drizzle in the West and North but with lighter winds later in November temperatures should improve into the mid teens. So get over the next 10 days and things should begin to dry out then.
The weather for October 2022 in Ireland is going to continue on a cool and unsettled theme. The nights are also getting cooler and the ECM hints at some frosty nights after next weekend.
Similarly there are also hints of some stormy weather at times especially next Friday or Saturday.
Cooler conditions are then forecast to take hold around the second week of October and there could also could be some frost or ice on some of the nights. Though it will be cool for much of October it doesn't look like it will be cool enough for snow yet in 2022. Maybe around 10c to 14c and with those high energy bills that isn't really good news is it?
