    FLISH at about half-past four, followed by KRAKOOM a few seconds later.

    The first FLISH was bright enough to be visible through blackout curtains and eyelids. Did anyone spark up blitzortung to see where it hit?

    Thought I’d dreamed the thunder. My wife didn’t even wake up!

    I was awake and heard the sonic boom. Thought it was aircraft. Then heard the next one and saw the lightening. I opened the curtains expecting a sound and light show as back in August, but it had ended with that bang.

    I was woken from slumber by the thunder claps (I counted two), then struggled to get back to sleep due to the howling wind and lashing snow/sleet/rain. We sleep in an attic space so when the elements do their worst you really notice it. The face seemed to come from directly overhead - the roof literally shook, I thought the skylights would implode...

    I was woken by the first thunderclap, got up to look outside and noticed the snow was deep and crisp and even. I wasn't sure if it was raining or sleeting, but realised we'd had the fabled thundersnow.

    Went back to bed, then moments later the huge flash of lightning got me out of bed again and I watched for a few more minutes, then decided to go back to bed, reasoning that with so much white outside I might damage my eyesight if we had another big flash.

    @IWRATS: If the altitude is in feet then the temperature is in Farenheit, surely?

    Tell that to the aviation industry, much of which still uses feet for altitude (and nautical miles for distance, and knots for speed) but is quite happy with Celcius for temperature in TAF/METAR reports, along with hPa for air pressure and - perhaps confusingly - metres for runway length and visibility.

    Annex 5 of the Convention on International Civil Aviation (aka the Chicago Convention) states that SI units should be used, but specifically allows feet, nautical miles and knots "for temporary use". (It also allows Celcius as a permanent alternative to the SI unit, which would of course be Kelvin.)

    My Garmin GPS watch can be set to display altitude in feet but it doesn't seem to have heard of nautical miles or knots. For which I am quite grateful.

    I have told them, repeatedly. Hence that impromptu stop in Baku.

    When you say "hPa" do you mean "µPa"? That would be an excellent but little-used unit for those of us who keep competition grade mercury diffusion vacuum pumps at home.

    When I first had a cyclometer which measured temperature (or is that a thermometer for measuring bike rides?) It allowed me to convert between Celsius and Fahrenheit. In doing so you had to accept also measuring in Km and m or miles and feet.

    Fahrenheit to real unit conversion wasn't a skill I wanted to spend time practising and I've been riding bikes in Kms ever since.

    Thundersnow, also known as a winter thunderstorm or a thundersnowstorm, is an unusual[1][2] kind of thunderstorm with snow falling as the primary precipitation instead of rain. It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different from any other type of thunderstorm, but the top of the cumulonimbus cloud is usually quite low. In addition to snow, graupel or hail may fall as well.

    So now you know!

    We’re now arguing over riding or walking to the market. (Haven’t changed tyres yet...). Saw a neighbour walking dog slip on the slush...

    Floodgates up in Roseburn Park. It looks like the Water of Leith spilled over in some parts but contained now, though full and very swift.

    Still raining.

    The water levels were high with run off at Balerno end of WoL last evening - so added to the downpours does spell big trouble in Little Saughton for sure

    Big - as in wide - puddle at the foot of the ramp before you cross Morrison Rd. would be treacherous if temps fall (but I don’t think they’re expected to).
