The Cairnwell (Perth and Kinross) weather

Headline:

Frequent heavy showers today, some thunder.

Today:

There will be frequent heavy showers throughout the day today, particularly into the afternoon with the chance of thunder. Some bright spells at times, mainly in the west. Light winds. Maximum temperature 17 °C.

Tonight:

Some heavy showers will continue through the evening but mostly dying out by midnight. Dry with prolonged clear spells through the second half of the night. Minimum temperature 11 °C.

Wednesday:

A dry and sunny start to the day, staying mostly fine through the day but chance of the odd light shower. Maximum temperature 21 °C.

Outlook for Thursday to Saturday:

Chance of a few outbreaks of rain Thursday morning, mainly dry and bright into the afternoon. Mostly dry Friday with patchy cloud. Rain pushing eastwards Saturday, heavy for a time.

Early in this period, low pressure is likely to exist to the northwest or north of the UK, allowing areas of cloud and rain to spread across the UK from the west, though some more settled interludes are also likely, especially in the southeast. Breezy at times, with temperatures mainly near or below normal. Remaining changeable thereafter as weather systems to move across the country from the west, with northern and western areas typically wettest and a greater chance of dry conditions prevailing in the southeast. There is, however, a smaller chance for either unsettled weather to be more widely prevalent, or for a more quiescent period to develop across the south. Overall, temperatures will likely be near normal, but may feel cool in the west at times.

Through this period, there remains a slightly increased chance of more settled spells of weather developing at times, particularly in the south, and the likelihood of this has been gradually increasing over the past few days. However, there is still a substantial chance of other outcomes too, with more changeable periods also likely. Overall drier than average conditions are more likely than wetter than average, and warmer than average conditions are weakly favoured too.
