Cut-Off Low ShenanigansAdded : Sunday at 15:00 It's been a while since we have had a week dominated by low pressure but that is exactly what is in store for this week. What's more, it's going to be the same system dominating through.
Here is the pressure chart for this evening:
And the corresponding jet stream chart:
There's your cut-off low and it's quickly apparent that it won't be going anywhere very fast because there's nothing to move it on, and so this proves over the coming week. Tomorrow it is still to the west:
And it's barely moved by Tuesday evening:
It does start to shift slightly further east on Wednesday:
A little further by Thursday:
Before finally clearing to the east by Friday:
So it's an unsettled outlook for this week and all of us will see some rain before the week is done, even for those parched areas of eastern and south-eastern England who are still waiting to see some rain.
It's an evolving situation though with an unstable set-up meaning that showers or longer spells of rain circulating around that low are hard to pin down in terms of timings and exact locations. For the next couple of days though we can highlight this evening and tonight as a time frame when another area of rain and showers, locally heavy and thundery, push northwards:
Again, it will be western regions that see the wettest conditions with little, if any, rain for parts of the east. That area of rain clears north tomorrow and for many areas it will actually turn bright and rather warm:
But that warmth could trigger more in the way of thundery outbreaks as we go through Monday evening:
As that low moves east during the week so those areas yet to see much rain should end up seeing something although the nature of the set-up is that rainfall totals will be quite variable with some significant local differences.
