  1. Yeah, we had heavy rain yesterday morning with some distant rumbles of thunder to the south, more showers in the afternoon and evening (and a few more distant rumbles to the south) with a heavy downpour around before midnight. Going by the manual gauge (though the Davis was almost identical), we totalled 26.0mm yesterday and 5.0mm today. Fog this morning gradually lifted with sunshine this afternoon, and it was warmer reaching 15.7C. Foggy again this evening (shallow mist/fog started to form as soon as the sun went down). Edit: thought I was in the SW regional thread hence talk of fog and stuff
  2. Too much mixing and/or cloud prevented a decent ground frost (or air frost) here this morning, though there was a bit of ice/frost on the car and a felt roof across the road first thing. Min was 1.6C at 1am. I notice Yeovilton in Somerset had a min of 0.1C yesterday, and 0.0C today. So close... (I believe -0.1C is required)
  3. We had 2.2C at 3:05am last night which was the lowest so far, though it rose a bit towards dawn due to some cloud cover. It's already 3.2C here at the moment so we may get at least a decent ground frost if cloud doesn't come in. Probably not quite an air frost from my experience here, but It's possible.
  4. Min of 3.3C yesterday then a lovely almost completely sunny day reaching 16.7C. Not quite as cold as it could have been last night (min 3.7C) due to a bit of cloud probably, however there was a very rapid temperature rise as occasionally happens here when the valley inversion (which had got increasingly shallow) was disrupted by the increasing breeze that had been going over the top of the colder layer: I could see the light breeze start in the tree tops on slightly higher ground just before it happened.. I also saw something I've never noticed before, which was a heat shimmer effect in places due to the air of different temperatures mixing. I walked to work across the fields as this was occurring and colder and warmer areas were perceivable.
  5. I've occasionally noticed small/pinhole eyes doing some kind of "trochoidal oscillation" as if they were not at the very centre of rotation of the storm's mass as a whole.. Hurricane Wilma was a good example with an excellent satellite animation (the 2nd one) here: (Edit: it almost seems like it was rotating around the edge of an attempt at a larger eye/eye wall replacement (which does occur later) Not sure how common or well recognised such motion is.. but perhaps the recent SW motion (actually very slow and more direct S in the latest frames) could be due in part to a similar effect with Matthew?
  6. I think you have misinterpreted me as that was exactly my point. The original post I quoted suggested a 'very chilly picture' from charts showing low (blue) 500mb heights over us, I was pointing out that that doesn't necessarily mean cold weather at the surface, and indeed it doesn't with those charts.
  7. Yes indeed, wasn't sure whether that was the case but thought I'd clarify at least for anyone reading, that didn't know that those charts are not nearly as cold as the 500hpa height looks. Those charts would give mid-teens at least for some between rain bands (and mildish nights) especially with sea temps still that high, though of course feeling chilly compared to most weather recently, as you say.
  8. These charts themselves aren't particularly cold really, more around average as the 500hpa Geopotential height does not correlate well with nearer surface (or 850hpa) temps
  9. Not sure which way it will go but 11.2C please.. and I'm actually on time for once
  10. I had 4.7C here then Also 2014 gave 3.4, 3.8 and 3.8 degrees on the 20th, 21st and 24th, and July 2015 had 3.7C on the 31st. Seem to have had a number of notably cool minima in recent summers.
  11. Min of 4.9C last night, coldest since June 4th (4.8C) I have actually scraped an air frost in September before, 2010 at -0.1C (and even a ground frost in August with 3.0C on the 30th in 2010). In contrast 2009 waited until December the 1st.
  12. autumn

    Same here! Although I spent most of those storms in Egham wishing I was back home in
  13. Saw a few distant flashes from that stuff out in Lyme Bay, earlier and more recently, and a couple faint atmospheric flashes from the East Dorset storms when I looked. Sadly that's as good as it's gunna get Another good example of how the ATD always seems to become less accurate and misses lots of strikes at night: Do half the detectors have to sleep or something? Edit: radar removed shows it clearer. Blitzortung often 'over-counts' but not that much. Just curious as I thought it was meant to be the 'gold standard' of UK lightning detection or at least very good.
  14. That is a good point, I did realise that but didn't think/forgot to mention it in my post
  15. I'm also unsure about today.. Euro4 less keen to break things out for the western risk area i.e Dorset until later into the evening/night now (this for Midnight): though it does also seem to be showing lower temperatures than are already occurring. I wouldn't mind some after dark lightning photo opportunities if I do venture into Dorset later though. Then it seems keen on stuff for the SE (no idea why those links won't embed as a picture like the top one)
