Near term, a slow moving shallow low trough will aid shower development over the bank holiday. Unusually the warmest air currently is over NW locations, quite a strange set up. Some places will escape with a fine weekend, others could see a fair amount of rain. Western parts will see low cloud and drizzle tomorrow. Temps average or above for all. Sunshine could be fairly limited for most. Could be alot worse but also a fair better.
Next week likely to bring the first nationwide fine warm dry spell, warm but not especially so, hopefully lots of sunshine and under the ridge with light winds will feel very good indeed.
Difficult to pinpoint cloud amounts and where will see the highest temps. Later in the week, SE parts may see more appreciable warmth.
Where we go as we head into the middle of the month is questionable, longer range models were suggesting a retrogressive high and a cooler northerly flow, but are now showing the ridge sink SE allowing the atlantic to move through. No obvious signal we are seeing the foundations for a lengthy warm dry spell, but I guess most will be happy to experience a few days of such conditions at least.
Here, we have seen a preety decent couple of weeks other than Monday its been dry, often can be the case NW is best at this time of year.
