A cool week ahead – some sunshine but less sunshine than of late and also some showers as high pressure loses control of our weather.

Thanks to Paul for the photograph.

Tonight sees clear spells at first. Some cloud spreading down from the north later in the night and a fairly cold night again, down to around 1’C – a frost in places.

Tuesday will be generally fairly bright but with a fair amount of cloud, making this hazy. Some showers will develop as the afternoon goes on and into the evening as an area of low pressure treks south – possibly heavy. 15’C. Fairly cloudy overnight, still a chance of a shower though most will be to our west, down to around 5’C.

For Wednesday we have low pressure over us – something we haven’t seen for a while, and this will pull in a chilly north-easterly wind – chilly winds we have seen plenty of!

There’s a bit of uncertain as to how widely showers will break out – more likely we’ll start the day fairly cloudy but bright with some hazy sunshine – showers breaking out during the morning and perhaps turning into general showery rain as the day goes on. However, this could be a bit further south, so a small chance instead of a dry day – we are kind of on the border. Assuming some hazy sunshine, then around 13’C. The cloud and possible showery rain will clear south overnight – clear skies and another chilly night, down to somewhere between 0’C and 5’C – depending on how quickly skies clear – so a risk of frost.

Thursday starts sunny. Cloud will bubble up to become mostly cloudy from around lunchtime – still a bit of brightness, but limited. A few scattered showers during the afternoon – but only around a 30% chance of catching one. 12’C and feeling chilly in the northerly breeze. Variable cloud overnight, down to around 1’C with a frost in places.

Friday starts sunny. Cloud will bubble up though there will be some sunny spells throughout the day. Some heavy showers will develop, around a 60% chance of catching one or two. Around 12’C in a chilly northerly breeze. Variable cloud overnight, down to around 1’C with a frost in places.

Saturday starts sunny. Cloud will bubble up again, though a bit more sunshine than Friday. One of two heavy showers possible, around a 40% chance of catching one or two. Around 13’C though still a chilly northerly breeze. Clear spells overnight, down to around 2’C.

Sunday looks like high pressure might just start trying to build from the south-west – though more notably there are two low pressure systems to the west.

So it should be fairly sunny, some cloud bubbling up and again a chance of one or two heavy showers. Around 13’C but we’ll have lost the chilly northerly – perhaps 15’C at a push.

Bank Holiday Monday is uncertain at this stage, but slightly more likely is for wind and rain to spread east – the slightly less likely option is just a continuation of the sunny spells and scattered heavy showers theme. Somewhere around 13’C, give or take, in either outcome.

Any sign of summer?

No. The more likely outcome for next week is a short unsettled spell – wind, rain and/or showers – followed by another chilly northerly.

There is a window of opportunity for a warm-up from around 7th May – but if low pressure entrenches itself next week, then we could easily end up with a couple more weeks of cool and unsettled weather – before the next window of opportunity.
