now no more than a few spots and almost certainly about to die out
completely. Rainfall since 09Z this morning = 5.5 mm/ 3C drop in
temperature during heaviest rain.

... no more thunder heard after last entry. Rain ceased properly at
same time.

NOTE: this is the first 'thunder heard' day here this year, and since
23rd December last (late afternoon/early evening).

Martin, no thunder here (Evershot), unless I'm going deaf. But we had
similar rain to you: 5.0mm at 10z-1120z. And we've just had another
sprinkle around 1505z. Temp drop during the rain this am was 17.9C to
15.6C. Still looking quite threatening now (1515z).
