Morning all. Luckily, I'm visiting family in NE Wales at the moment, and managed to bag a couple of storms that passed through around 6pm. No photos unfortunately, but a quick summary of events, nothing too exciting, but good for the record (mods, if you want to move this to a more appropriate thread - crack on!):
As expected, the day was very hot and muggy, and noticeably hazy. We spent most of the afternoon in the Dee Valley on the Llangollen Railway, so in a fairly good position to see a substantial cumulus develop to the east and south east from mid afternoon. The development of which had become incredibly rapid by 5pm. Even the non-weather types with me commented on how fast the clouds were bubbling up, and it was indeed exceptionally fast convection, but rather difficult to appreciate without sunglasses owing to the hazy skies. To the SSE at the time were cirrus anvils of cells over towards Shrewsbury and Birmingham were making themselves visible over the tops of the hills at this time too. This explosive convection coincided with our return back to Broughton in Flintshire - temperatures at the nearby Hawarden Airport reaching 29c during the afternoon - where we found ourselves catching up with the lines of thunderstorms that had broken out from the cumulus line and explosive convection seen to the east about 30 mins earlier. Some fairly substantial rain and thunder. Couldn't see too much lightning, but did catch one or two positive CG's on the drive back. Once this cluster of storms had passed through Broughton and carried on NW toward Liverpool, another pair of cells came in about half an hour later from the Crewe/Nantwich direction, noticeable by the substantial outflow preceding the arrival of the cell. The wind had become very squally. Some interesting structure on the underside of the leading edge. Gust front maybe? On radar this showed a lot of promise but I think the preceding storm had sapped some of the energy out of the atmosphere, as this later storm was something of a damp squib. It weakened considerably as it passed overhead with only marginal lightning and thunder, and moderate rain. Post storm the wind died back to almost zero, making for a very humid and close evening. Further moderate rain continued during the evening, but generally the main event was over by 7.30pm - 8.30pm.
All in all, managing to surreptitiously throw in a short chase in the midst of a family day out (taking the scenic route back from Llangollen over the Llandegla moors...'lovely scenery up there, let's go for a detour' says I, fooling everyone else in the car), quite happy with the storms we saw.
More due today. Over on the Cheshire plain this afternoon, hopefully may even get chance for photos today too.
