    Storms and Convective discussion - June 2023

    in Storms & Severe Weather

    Posted

    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.

    Nothing doing here yet. I'm in Corton on my hols

    I think I generalised a bit by saying Lowestoft. Being more specific, the cell in question would have been to the south of you in the Southwold/Halesworth area. I've attached a screenshot from the 2130 radar return which shows the cell at it's strongest. Looking at the radar in conjunction with lightningmaps, it seemed to be electrically active for about 20 mins or so before dying as it moved further inland.

    Love the photo of steady light rain.  We don’t see enough of them on here!!  

    I’m still hopeful there will be a second wave of storms further west, you can see it on the radar:

    How exciting it will be is anyone’s guess, but that’s always the way with these situations!  We will see….

    Pretty much pinning my hopes on the western edge perking up later on this evening. Raining here at the moment, and as refreshing as it is, it's not exactly exciting.

    I know, right? Mad how quick it crept up. I was above the storm just south of Alton which was dying off when I could hear a constant rumbling. Took a few minutes to realise it was just behind me and a different cell

    I think that storm south of Alton was the one I could hear rumbling away earlier on around 2pm. Pleasant surprise this afternoon to get all that constant rumbling, and a decent splash of rain too - even if the core of the cell was a little to the south.

    Right under the storm now. I was lucky I saw it form over Basingstoke and headed west just in front of it. Close lightning but mostly elevated atm. Have my ear defenders on lol

    It took me by surprise by how quickly it formed. We had a small thunderstorm pass by around 2pm, then around 3.30pm heard what I thought was wagons being unloaded at the unit next door to where I worked. Popped out for a look and saw a lovely black wall of cloud to the east and south east booming away. Still going now, hoping for a more direct hit later on.
