Highs of 16 today here, 18 tomorrow potentially but from Sunday onwards we're only seeing highs of about 15 and lows of 8, so very different indeed!”
I don't believe this at all either.. I live about 150m above sea level, and frost in September is almost unheard of here.. These Observations come from the Bingley Salmos Weather Station (nearest one to me) and that is about 260m above sea level:

Overnight temperatures not even close to being a frost (temp needs to be at or just above freezing).
Nakatomi also claims that in her part of the north west she's getting moderately high temps during the day - it was also 16C here day, same as me. But for temperatures to then drop to near freezing level from the mid-teens in the course of one day - it just doesn't add up

I don't know which part of the North West you're from, but either you live in some crazy microclimate in the middle of nowhere, or you live at the top of a mountain (and then walked down to the bottom during the day where it was warmer)...
BTW, I was out today in a t-shirt, and out tonight in just football shorts and a football shirt (I do footie training) and even before I started training I was fine..
It isn't cold....

Both these are low enough to produce a ground frost in clear skies/low wind speeds as it was, including car roofs open to the air.
Leaving aside the indoors-outdoors-garage banter on this page, what he originally wrote yesterday i.e. :
... is perfectly feasible, in fact highly likely in parts of N.I. yesterday morning. For comparison, my own minima this morning (we seem to be running a day behind the NW!) were: air 7.3C; grass 2.6 C - and the grass needs cutting which tends to keep it a bit on the high side.
Note to self: Cut the blooming grass this afternoon!

I don't understand this one either...
Firstly, you live in the far South of the UK where it barely gets cold, I thought frosts were quite rare down there....
How can you measure the temperature of grass????
And, if the grass is really that cold, how is it still growing if it's nearly at freezing point??
