It will be hotter.
We are going to get some summer warmth midweek and heat at the weekend. Many will be pleased after plenty of wet weather, and after all, it is June. Others don't like the heat, particularly the humidity and the grass pollen season is now in full force.
Heat has been building over the Iberian peninsula with inland Spain reporting temperatures of 37C already and 40C likely in Andalucia by the end of the week. With high pressure building to the SW of the UK, the very warm air over the continent will be drawn up over the British Isles.
Temperature forecasting will often result in one figure on a map over your region, but it's sometimes helpful to bear in mind that looking few days ahead there could be a range of values for any given place. For Today, Tonight and Tomorrow the accuracy of forecasting temperatures is high generally. A slower clearance of rain and cloud can cause problems, showers great fluctuations but overall this is a good part.
The temperatures information produced by the models is analysed, and an upper and low bound is decided upon for a location, then the most likely Max temperature. So say some early fog is likely but should clear you might get 21C, but if the fog is slower to clear, there may only be time to reach 18C, or if the fog barely forms then 22c could be possible. LB 18 UB 22, forecast 21C.
Looking ahead into the start of next week, there is an upper bound of 34C showing. It seems possible temperatures in SE Britain will creep up to 30 or 31C with a low probability of slightly higher. This heat will only result if we get a sequence of hot days and warm nights, allowing the ground to store up heat. The record for June is 35.6C recorded on the 28th 1976 in Southampton.
Just because bookies start to cut odds on the UK breaking temperatures records, doesn't actually relate to a proper forecast, they just want your money. This happens every year, yet the UK record of 38.5C (101.3F) stands from 2003

You get the picture.
Our Netweather MR (Medium Range) model does show heat for the weekend with temperatures in the high 20s. Widespread warmth on Saturday (away from NW Scotland) and heat again for Sunday particularly for England. Monday seems to still be hot in the south, but weather models vary about a front moving down from the north. This could introduce fresher, less warm air for next week. Other models keep the heat for longer, which could result in the 34C Upper limit.
There are signs that heat could return for the following weekend, but that is quite a way off, and it is Glastonbury by then, so hot summery weather would seem unlikely. A bit like a forecast showing warmth and sunshine for a Bank Holiday Monday, no-one could quite believe it.
