Big flash of lightning and deep booming thunder in Letterkenny with torrential rain.
First flash of lightning I've seen in more than 2 years!
Chance this could affect The Open?
Very surprised though that such standard looking synopics would bring thunder? I.E, approaching warm-front and long-wave SW pattern. No thunder here but getting increasingly frequent, if very short-lived, torrential bursts of rain and feeling as humid as hell.
