With waxing & waning of northern blocking persisting, it will be difficult to build any very warm spells of weather over the next few weeks

But some pleasant spells with temps average to slightly above average are certainly possible at times

Perhaps some real warmth mid-end May

Whilst high pressure is expected to dominate until at least end of April if not further into May...

there remains a chance of cut off low pressure systems bringing wetter & windier weather to parts of the south in the last week of April

Only a small chance but worth the mention

Regarding above tweet for the end of April

At this stage, it does seem like we'll see some showers creeping in from the 28th April

However, there remains considerable uncertainty regarding this pattern so we need a few more days to firm up on end of April forecast

As we've been looking at in this thread, it is possible that from mid next week, we'll see a small shower risk creeping into the forecast

Whilst this scenario has higher confidence further north in UK, there does still remain uncertainty regarding how far south showers will get
