Stormy Weather II

[Serial_Apologist]

The first visible frost of winter, following the coldest night at -3C since Feb 23rd and coldest maximum today at +4C since March 7. Cloud from the frontal band of sleet and snow affecting parts of the South Coast earlier on lingered on until lunchtime, affording enough weak sunshine warmth to raise that temperature, but it has already at time of writing dropped back to +1C, heralding an even colder night tonight unless cloud blows in from the North Sea. Like Gurney I brought my five outside planted pots in under the cover of the V-shaped open porch area I share with my neighbour. Having failed to do this last winter I lost a couple of Pellargoniums. Her door is directly opposite mine, at an angle of about 70 degrees. I don't think she realises that I clear fallen leaves from under her outside door mat whenever I do my own.

Steady flakes of snow here late this morning, and pretty cold, unsurprisingly.
Going to make for chilly weekend jogging…..when the going gets tough, the less than tough get their ear muffins on……

It ain't half cold mum . Roll on next week - it might get up to 5 or 6 degrees

That would still be 2 or 3 degrees lower than the mean for the start of December, both for London and for Bristol.

True, but a few degrees higher than it is going into the weekend.

Came out of choir rehearsal this evening to find there had been a shower of little white snowy pellets. There were a few stray small flakes falling and it was beginning to freeze but not enough to cause problems with car windscreens, although the forecast is for it to get much colder during the night.
The tender container plants will have been finally finished off now so in due course I can do the final tidy-up to remove them and bring forward the pots of hardy items, including a couple of winter flowering shrubs which will be moved nearer the back door so I can get the benefit of the sight and scent.

Hope everyone is OK, as the wintery weather appears to be pretty widespread across the country. It was another very cold night here and as thick fog is being very slow to clear it's not pleasant out. I suspect that the sun is going to lose the struggle to break through before the end of the afternoon.The assorted snow flurries yesterday were mostly of the graupel type and where they've frozen it makes for a hazardous surface - slippery ball bearings! - to add to the frozen puddles and thin glaze.

Suggested Saturday attire…

Set out to do shopping at just before 11am and the weather app said it was -2 (back now after civilised lunch out and it's -1). Very strange that my breath wasn't steaming up on the cold air even though my fingers (I foolishly wore fingerless gloves instead of proper ones) felt as if they would fall off. Is there a scientific explanation for that?

....your fingers being cold....scientific stupidity....useless expert (quote Gove)....

Here's a hand-wavy exaplanation (courtesy of Dr Magnus Pike) that might well be wrong
It needs to be below the Dew Point to condense to liquid water and become visible. The Dew Point occurs when the air is saturated and can't hold any more water (as a gas), it depends on relative humidity and temperature...
I think it needed to be more humid for you to be steamy.

Struggling to find a weather station near to you...
But, here's one somewhere in Bristol https://www.wunderground.com/history...b/bristol/EGGD

Time	Temp	DewPoint	Humidity
10:50 AM	0°C	0°C	100%
11:20 AM	1°C	0°C	93%
11:50 AM	2°C	1°C	93%

(There might be a closer weather station in this list https://www.wunderground.com/weather/gb/bristol )

I have a vague memory at the back of my mind that it is to do with humidity. If it's very dry moisture in your breath evaporates rather than condensing into drops that are visible.

Well, it hasn't rained for a couple of days. On the other hand, I could have been dreaming. I've just opened the back door (still -1) and hhhhhh'd loudly and there was the expected cloud.

Hard, hard frost overnight, and STILL unthawed' now tiny sweeps of snowy sleet promise to re-freeze overnight making Sunday deadly underfoot.

I hesitate to suggest this...
But, could it be a sign of a steamy French homelife?
