As we head toward mid-September, the weather is taking a turn back into Summer with some very warm, if not hot air with us during the first part of the week. Temperatures are likely to move up into the low-thirties in parts of southeast and eastern England before things start to cool down from the north midweek.
Temperatures of 30c or more aren't especially uncommon in September, the record for this month is 35.6c, recorded way back on the 2nd September 1906. That isn't going to be in danger this week. The daily record for the 15th (Tuesday) is one to watch though - that is 30.6c, recorded in 2016. The latest date in the year that 30c has been exceeded in the UK is the 27th September - which happened in 1895.
Much of the UK and Ireland will finish up this weekend with warm sunshine with temperatures heading up into the high-teens or low to mid-twenties. The exception will be the west and particularly northwest of Scotland, where it's still raining. The wet weather will become increasingly limited to the far north and northwest through the day though.
Monday will see a little more rain in the north and northwest, with some showery outbreaks moving into Northern Ireland and the far north and northwest of Scotland. There'll also be more cloud across the northern half of the UK, but for the bulk of England and Wales, there'll be long sunny spells and increasingly warm temperatures. 30c is on the cards for the southeast, with temperatures in other regions heading up comfortably into the twenties.
Tuesday sees a continuation of the fine, hot weather with maximum temperatures again likely to reach into the thirties for parts of the east and southeast. There may be a few showers in the west and northwest, but in the main, it'll be dry for just about everyone with the warmth even spreading right up into Scotland.
Change will start to arrive into midweek though, as pressure builds further north and a weak cold front moves south, introducing fresher, cooler air behind it. The southern half of the country will stay very warm on Wednesday, but it's very likely that all parts will be into the fresher air by Thursday.
With high pressure to the north or northeast of the UK during the second part of the week, we'll keep the mostly settled weather going. But with east or northeast winds blowing, it's likely to be western and southern parts seeing the warmest temperatures, which will peak into the low-twenties. Further east, with those winds off of the North Sea, it'll feel cooler - especially near to the coast, where there'll also be some extra cloud drifting inland at times.
