Sorry this is a rather lazy question.

I planned to test out my brand new DSLR in the Wey Valley at sunrise this
morning but overslept. Did any hardy souls out there see much hoar frost
worthy of early trip tomorrow ? My back garden station (Burpham, Surrey)
indicated a min of -5.4c last night so no lack of cold air.

Many thanks

Terry

Air is too dry for heavy hoar deposits, probably be the same
on Sunday morning. Have fun setting that alarm for 0500z )

It's usually chilliest just at dawn, or just after is it not?

I tested out my old Ford Transit on some cooking oil about 06:30
morning in a nice crisp frost. It's still frosty now but the engine is
warmed.

I had a 50:50 mix of diesel and cooking oil in it and it started first
time.

I know it is going to be frosty each morning now until the end of this
spell and again next week apart from some cool misty weather in-
between. So I had better run the thing dry and fill with veggie oil
tonight to try it out again tomorrow before it is too late to sort it
on Monday.

I have no idea what I am going to do if it wont start. Take the fuel
lines off the injectors and pump it out probably. Sounds fun in a cold
corner. I'd better get a fuel container and a gallon of the real
thing.

Bloody politicians! Why can't we have a violent overthrow now and
again? (A very violent overthrow.)

What was point of changing it Mike?

Go and take some pictures anyway - and if there's no hoar around, then adobe
(elements or cs) may be able to help. Looks like dawn will be picturesque
whatever.

Because it was still on the subject of the weather and yet off the
thread topic.

Also I cross posted it to a car group as there will be a lot of frost
around until the end of the month and for all I know from looking at
the phases, until the third week in March:

Who knows what use the info might provide there? It could be useful.
I'd like to know if I had to get up an half hour earlier to deal with
a frozen windscreen or worse. If I was burning old chip fat I'd be
especially interested.

No. It's between 4-5am.

As a Brit I'd like to thank the Americans for their help in the war
against terror because if they'd not funded the IRA for 30 years, we
wouldn't know how to deal with terrorists.

At this time of year (with clear skies) it's coldest here in Somerset at
around 8am - the Sun isn't high enough to warm just after dawn, so cooling
continues until it rises high enough to affect the air temperature.

Being a dirty smoker who's worked nights for the last 8 months or so, I can
confirm what Conor says. It's always bloody cold whatever season between
4-5am when I go out for a cig :-)

There must be a reason why it feels colder at dawn then. Would it be
regionally specific, I wonder?

As the frost forms around 4 to 5 am, the latent heat is swept away
according to the laws of physics. On a calm morning it will get
momentarily warmer and just at about the time most people become aware
of it, the temperature drops back down to the pre latent heat
temperature?

Whatever the reason, there has to be reason.

As a Brit I'd like to thank the Americans for their help in the war
against terror because if they'd not funded the IRA for 30 years, we
wouldn't know how to deal with terrorists.

They only stopped funding terrorism in Britain because Tory BLiar
promised to terrorise Iraq.

In that TV show that took the lid off the causes of the war about a
year ago, he looked like he'd just been freshly buggered. Must have
been when the impact of what he'd agreed to behind our backs hit home.
