St Just (Cornwall) weather

Headline:

A grey start but some very warm sunshine breaking through.

Today:

Rather cloudy and humid at first with some patches of hill fog and the odd spot of drizzle in the west. Skies generally brightening up, especially in the east where it will feel very warm in the sunshine. Maximum temperature 26 °C.

Tonight:

A band of cloud will edge eastwards across the region during the evening, breaking up to leave a fine night with clear spells. Remaining fairly warm in light winds. Minimum temperature 15 °C.

Wednesday:

Wednesday looks set to be a largely dry day with a fair amount of sunshine. Perhaps an isolated shower developing, mainly in the east. Feeling fresher than of late. Maximum temperature 24 °C.

Outlook for Thursday to Saturday:

A ridge of high pressure will give a mostly settled day on Thursday, with some sunshine. Slowly clouding over on Friday with damp and breezy conditions developing heading into Saturday.

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.

Changeable conditions with a predominantly northwest to southeast split in temperature and rainfall, and the potential for further occasional episodes of hot weather and thundery outbreaks, are considered likely to gradually give way to something more settled and dry overall through the second half of July. Temperatures are likely to be above average, with the greatest chance of very warm or hot spells in the south or southeast.
