Contradictory temperature charts

Dear Diary,
Temperatures are only just going to manage to get up above freezing for a short while across the Highlands this afternoon. The air temperature at Aviemore was -1.2°C at 1100 UTCUTC Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT)., and here in StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469. it’s just 2.2°C at 1215 UTC. Just caught the latest forecast from the BBCBBC The British Broadcasting Corporation (BBC) is the national broadcaster of the United Kingdom, based at Broadcasting House in London. It is the world's oldest national broadcaster, and the largest broadcaster in the world by number of employees, employing over 22,000 staff in total, of whom approximately 19,000 are in public-sector broadcasting. on the News Channel. SKLSKL Sarah Keith-Lucas an English meteorologist and BBC weather presenter reckons that it won’t be quite as cold as last night with only a patchy frost overnight particular across Scotland, and then goes onto show this rather contradictory graphic of temperatures at 06 UTC, with labels of temperature that bare no relation to the NWPNWP Numerical weather prediction uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. blue contoured data that they overlay on the chart which also seems to be missing a few labels as well.
With a maximum of 2°C so far today I would make an educated guess that we’ll see a widespread moderate frost across the Highlands overnight and not at all patchy.

Highland temperatures

Dear Diary
I don’t know how we managed to avoid a frost last night but we did with a minimum of 0.3°C at 0017 UTCUTC Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT).. After that I imagine the cloud must have increased because the wind remained very light from the W’SW. The unusual thing is that although you would expect the minima to occur at around sunrise (0831 this morning) it didn’t. Instead the overnight cloud quickly dispersed and we were left with blue skies, but temperatures continued to fall back from 3.9°C at 0700 UTC to just 1.2°C at 1100 UTC. This is because as the name suggests StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469. is in a strath and from about the end of November the sun never gets over the Cats Back (a long ridge to the south of the village). The sun eventually struggle over the ridge but it takes till mid morning to do it. The Highlands are full of glens and straths like this, many of them won’t see direct sunshine again until the end of February.

Back edge of front casting shadow

Dear Diary
I missed this lovely satellite image today whilst clearing leaves out of the gutters and chopping sticks for the fire. The sharp back edge to the frontal cloud is casting a shadow northward across the Lake District and NENE North East England. Meanwhile troughs within the colder air, containing CBCB Cumulonimbus cloud. Well-developed cumulonimbus clouds are characterized by a flat, anvil-like top and thunderstorms, are running into western Scotland and Ireland from the west. Meanwhile in StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469., and much of southern and eastern Scotland, it’s remained dry with long sunny spells

Fog persists across Easter Ross

The overnight fog has been persistent across the Cromarty Firth and Straths and glens of Easter Ross this morning. In fact temperatures are still subzero after a moderate overnight frost. Here in StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469. temperatures fell to -3.5°C in the first frost of the Autumn. The fog looks to be around 300 feet thick or so and is blowing up the strath from the east. Higher up above the inversion at around 750 feet there’s a 5 to 10 knots wind blowing from the south. So as well as fog blowing up the strath from the east some is blowing up and over the ridge of the Cat’s back from the south. You can barely see what all the fuss is about in the lunchtime satellite image.

My shadow cast a faint gloryGlory A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds. The glory consists of one or more concentric, successively dimmer rings, each of which is red on the outside and bluish towards the centre. Due to its appearance, the phenomenon is sometimes mistaken for a circular rainbow, but the latter has a much larger diameter and is caused by different physical processes. as I walked along the ridge.

Bridge of Dee

I make the wettest place in Aberdeenshire, using estimates from weather radar, the bridge of Dee with 143.6 mm of rain since the start of Wednesday (16 November) till now. That’s the wettest residential site but there are some deep purple pixles and a couple of white ones indication totals above 225 mm. Here’s a league table of wettest residential places, and as you can see there are other sites outwith Aberdeenshire.
