Yes thanks for that knocker that's the grass or ground minimum. Often a few Celsius lower than the air temp.

[Turnedoutniceagain]

Nudged a low of 8.2 on Sun/Mon, but that's now gone up to 9c this morning. GFS showing hints of 4, possibly 5c in a week

[Mother Goose]

Our first frost was on Monday morning. De icing the car at 7.30am

Good to know, thanks for the record.

[damianslaw]

Mmm October at the earliest then for our first ground frost. Minima this month have been exceptionally high. In an average year we would have a had a handful of night by now in the low-mid single digits at least. Nothing on horizon suggesting anything particularly cold, too much cloud or wind, but at least temps overnight will be in the single digits. 

Looking forward to the first cold night of the year. It doesn't feel autumn properly until we have one.

[damianslaw]

Just me in here.. mmm slight chance of a couple of coldish nights inbetween the rain bands this week but not cold enough as skies unlikely to stay clear for long and wind too brisk. 

Nothing on the horizon suggest widespread frost any time soon.

[Aleman]

How does September 29th compare to prevous years? I'm guessing it's typically a few days earlier.

Shawbury Tg -1C this morning

[damianslaw]

Widespread air frost expected in NE Scotland tonight. Many parts of eastern Scotland and possibly sheltered eastern parts of Engkand may see first ground frost of the season before the next front moves in.

[Aleman]

-1.4C at Aboyne so probably a few localities in Scotland saw 0C.

I see Topcliffe hit 2.2C so it's just about possible some sheltered part of Yorkshire such as the Wolds might have hit 0C. Anyone seen 0C in England yet?

Closest I've seen in terms of official stations is 1.8°C at Bainbridge.

A number of negative Tgs in Scotland, -4C at Aboyne and one ot two further south. Benson and leeming -1C

[Aleman]

Altnaharra gets its second with -0.8C. Still waiting for England's first.

Post above stated Leeming and Benson went down to -1 last week. Chance Shap may go down to freezing tonight. Clearing skies through early hours could produce our first ground frost of the season.

[Frost HoIIow]

Looks far too breezy here tonight for any frost. Shame as skies do clear from midnight.

Nothing in North Yorkshire yet, quite late compared to recent years.

Ravenseat in Yorkshire Dales saw 0.6c in August and in September but no air frost just yet.

is Tgs grass minimum? We've seen plenty of ground frosts in Aug/Sep in North Yorkshire but still no air frost.

Yes

[damianslaw]

Anywhere go lower than 0 degrees this morning? 

[damianslaw]

High pressure on the scene days ahead but it's orientation not favourable for anything particularly cold by the looks of things. Too much of an Atlantic flow trapped around its flanks and consequently rather alot of cloud. Pity as I was looking forward to clear skies at night and first frosts. Chance though in any clear breaks a few spots may record their first ground frost at least. On average third week Oct brings our first air frost.. we should have had our first ground frost by now and want one soon to help turn the colours on.. very late change this year.. nature looking more akin to early-mid Sept than early-mid October..

Bit late but this was Wednesday.

Quite unusual but the only place to record an air frost this morning was Stenness in Orkney with a low of -0.3c.

Impressive for the Islands however it is in a deep valley.

[4wd]

Down to 5.3C here already this evening but it's supposed to turn cloudy after midnight.
