A northwest/southeast split will develop in the UK weather in the coming days,
with the possibility of heatwave criteria being met in the south and east, but
with some heavy rain further north and west.
There are marked differences in the weekend forecast for those in the
northwest compared to those in the southeast.
On Friday, those in Scotland, Northern Ireland, northwest England and parts
of northern Wales will see some frontal rain move in from the west through
the day, with the highest rainfall totals expected in western areas of Scotland
and Northern Ireland. That theme continues through the weekend, with
further bands of rain pushing into the northwest.
Meanwhile, much of southern, central and eastern England, will see a gradual
build in temperatures through the weekend. Temperatures will exceed 30C in
places and could even reach 32 or perhaps 33C somewhere in the southeast,
with Sunday the likely peak of the heat.
