In some regions, the Met Office warns there could be "further spells of rain, locally heavy across northern areas".
Elsewhere in the UK, conditions are set to be largely "fine and dry" and warm in the south.
Weather experts suggest there is also a threat of thunderstorms over the weekend.
Ian Simpson, forecaster for independent team Netweather, said: "It looks probable that we will see one or two relatively settled interludes early on in the period with ridges of high pressure moving in, most likely from the south.
"Temperatures are likely to be above normal early in the period, but trending average to fairly cool late in the period.
"It will probably be drier than average for most, particularly in the west and north-west."
Weather experts say the west of England, southwest of England and Wales will see conditions "sunnier than average".
High pressure is expected to shift to the north of England by September 20.

The shift is being described as an "anomaly" with typically warmer air for this time of the year.
A Met Office spokesperson said: "A weakening weather front on Saturday will split the country, with cool conditions in the north whilst southern areas remain mostly dry with some sunshine and feeling warm thanks to the humid air and light winds.
"Even during Saturday, there is the threat of some showers forming in the south and west with the chance of the odd rumble of thunder.
"However, these are expected to be fairly limited in extent with some focus in the southwest."
