I have viewed the Meteoblue forecast for Aug.01 (9h UT).
Bad news, I can say.
Cloudy and rainy weather over all of British Islands
, with +14...+19C in Ireland, +12...+20C in Scotland and +16...+27 in England&Wales. However some gaps in the clouds could arrive in Ireland.
Absolutely different weather in Ukraine -
totally clear with +18...+31C.
Have a look on the map:
If the forecast doesn't change, there could be a chance of partly cloudy weather in the SW coast of Ireland. Very unfortunate for British Isles. But most of the Europe will have a clear weather.
Totality pass forecast:
Nadym +13C, cloudy, rain
Nizhnevartovsk +15C, partly cloudy, rain
Novosibirsk +25C, partly cloudy, rain
Barnaul +26C, partly cloudy, rain
Biysk +29C, partly cloudy, rain
