Sat 5 Jul Wales

Following a fine couple of days in the run up to this period, away from the far northwest where more persistent rain is expected to develop, a transition to something more unsettled countrywide looks likely. Cloud and rain associated with an Atlantic frontal system and area of low pressure is likely to sweep south and east, with rain always most persistent on western hills whilst some eastern areas in shelter could see warm and humid brighter breaks. Likely turning cooler and more showery later in the weekend and into next week, followed by a changeable pattern with further areas of cloud and rain and brighter, more settled spells in-between. Temperatures are likely to be around average overall, with an increasing chance of warmth in the south as the period progresses.
