I'd rather you specified who "we" is referring to - there will be a fairly cold zonal blast for some around the 23rd / 24th so it's not all mild for the next week.
A period of zonal and very changeable weather coming up for the next 5 days or so, especially over Scotland / N.Ireland and parts of North England, where the weather will alternate between really quite blustery, damp, fairly mild weather (although feeling a lot colder in the wind) and colder weather with sleet and snow showers (feeling cold in any wind). More settled towards the SE of England, although temperatures could be supressed at night where there is little wind.
Thereafter, very much anyone's guess at the moment, very little agreement. Keep an eye on the 28 / 29th for a possible Northerly, far too far out for now though.
