    Stonking day for storms. Had two cells with continuous thunder [but mostly no visible lightning again]. Here's some pictures of one storm that I tracked as it progressed up the M11 which produced some

    Am enjoying a weekend away 60 miles S of Prague in the pretty town of Písek, the storm front that came in this evening was dramatic! 

    Didn’t know we was expecting an avalanche today 🤔

    Yeah as some have suggested just a pity this wasn't 2/3 months ago seems would be the perfect setup for perhaps some humdingers of storms (UNLESS i'm looking at it wrong........)?

    Had a report from Jersey of 3 lightning strikes, the last one looking blue.

    Any thoughts?

    Interestingly, ESTOFEX had much of the UK under marginal instability, even if it is from elevated parcels, this is what we could be seeing tonight.

    Not sure if it was a squall line that came through or something but the weather went absolutely nuts here at 6am this morning.  Woke me up 😞 House was creaking from the intense gusts and rain was slating itself horizontal. Lasted for about 15/20 mins or so.  Couple of links to nearby Wunderground stations.

    I must have slept through this in neighbouring Crewe or else we didn't get the same intensity of wind. Very wet underfoot at 7am but rain had cleared and black clouds were clearing off into the distance, to be replaced by blue skies and sun ever since.

    Day 1 Convective Outlook

    VALID 06:00 UTC Sun 15 Nov 2020 - 05:59 UTC Mon 16 Nov 2020

    ISSUED 08:06 UTC Sun 15 Nov 2020

    ISSUED BY: Dan

    A potent upper trough will swing northeastwards across the British Isles on Sunday. Initially, divergence on the forward side will encourage heavy precipitation to develop and run northeastwards across parts of the English Channel into SE England and East Anglia. Some weak instability will likely be present, bringing the risk of a few isolated lightning strikes - but the risk overall is considered relatively low (10-15%). Showery precipitation is also likely elsewhere on Sunday morning, moving northwards and eastwards with a low risk of lightning. Given the strongly-sheared environment, some line segments will be possible in places.

    The main focus for deep convection, and hence a greater risk of lightning (15-20%), will be from mid-late morning over parts of Wales and SW England as heavy showers develop and move inland. Hail is likely in several of these showers, along with perhaps a few sporadic lightning strikes. By the afternoon, a more organised comma-cloud feature associated with a tropopause fold is expected to quickly slide eastwards through the English Channel, pushing into parts of southern England. The most active portion of this feature is likely to remain offshore (and over the Channel Islands) where the greatest risk of lightning and strong outflow winds will exist - in fact there is fairly good model agreement on gusts of 70-80mph over the English Channel given a marked low-level jet. As a result, a SVR has been introduced for the risk of damaging winds (primarily offshore), and to a lesser extent for an isolated tornado - much depends on how active this feature is, and the exact track and interaction with the coastline of southern England. By Sunday evening showers will likely weaken and decay due to a combination of nocturnal cooling inland, and the upper trough departing.

    First lightning strikes inland are in Dorset. Meteologix has three of them detected as +CGs.

    • Cold waves hitting Europe continue to threaten growers, is there a link to climate change?

      Much of Europe, not just the UK, has experienced unseasonably cold weather since the Easter Weekend. A plunge of cold arctic air brought by northerly winds early last week brought several nights of frost and even snow across large swathes of Europe, followed by another wave of cold arctic air spreads across much of Europe this week. The frosts causing damage to new growth in vineyards and orchardsa0spurred on by a late March heatwave, the vineyards of France werea0particularly badly affected.
