After a relatively quiet but breezy Friday, torrential rain is on the way for Saturday. Two waves of hefty downpours, large hail & lightning. An amber as well as a yellow warning for heavy rain have been issued for the region - valid from just after midnight Saturday morning, until just before midnight on Saturday night.
Thursday night's cloud and thundery bursts of rain have now pushed away northwards and after lunch on Friday, skies brighten across the region. Just an odd shower possible over the Pennines. Breezy everywhere, but feeling muggy and oppressive. Heat health warning level 1 which is the lowest alert level - temperatures 26-27c tops 79f.
Mostly dry until later in the night then the first wave of showers and outbreaks of thundery rain push up from the south, lots of lightning and large hail. Winds generally light but gusty in any downpours.
SATURDAY A yellow "Be Aware" warning covers the north of the region for 1-2 inches (25-50mm) of rainfall in a very short space of time, with an amber "Be Prepared" warning covering the southern half of the region for 50mm of rain or more during the warning period.
After an unsettled start to Saturday with that first wave of rain, there will be a period of brighter, drier weather during the mid-late afternoon period. The second swathe of torrential rain pushes in early evening. Air still very warm with scope for temperatures in the low-mid 20's celsius. 23c across the Isle of Man. 19c across North Wales.
Overall, there could be 2-3 inches of rainfall from the entire weather event by the end of Sarurday. Locally 20-25mm of rain in an hour in a few spots.
Improving for Sunday.
