We were at exactly 0.0c, so no "official" frost, but temps have risen since then, still cloudy and 4.1c.

However, today is forecast to be much warmer than of late as we've now finally lost that wind from off the North Sea and it's currently around 9°C here in Edinburgh

In recent years, it has generally taken quite a long time (with that often not happening until well into May) for us to get our first 20+°C maximum of the year so for us to get so close to that today at what is still a very early stage of the overall spring/summer season is incredible.

There has still been a breeze throughout today but that breeze is coming from a completely different direction now, and feels a lot warmer as a result.

In the end, a total of 12.2 hours of sunshine was recorded for today at Edinburgh Gogarbank, so today wasn't quite our sunniest day of the year so far but that is probably only due to some high cloud making the sunshine a bit hazy at times and even that is still a very impressive total for this time of the year as this exceptionally sunny spring (probably at the very least, our sunniest spring since 2020 if this year isn't actually beating that up until now) goes on.

Meanwhile, the temperature has dropped back to around 13°C here in Edinburgh.

Minimum -3.2C, Maximum 22.7C, Range 25.9C

Currently around 9°C here in Edinburgh

In terms of the overall sunshine totals at Edinburgh Gogarbank, today won't go down as being as sunny as other recent days as there is a lot of high to medium cloud around which is making the sunshine rather hazy at times but even with that, the Sun has still been shining for most the time which means that even that cloud cover hasn't been enough to prevent today from being a generally nice and sunny day overall.

Today has also generally been not quite as warm as yesterday here in Edinburgh with the temperature only reaching around 18°C but the temperature at the botanic gardens in Edinburgh has once again got up to around 20°C which is on par with yesterday's highest temperature at that particular station although it looks as though our wait for our first 20+°C maximum of the year here in Edinburgh goes on for at least another day.

A couple of degrees off the date record.

This makes today our second warmest day of the year so far as it was only a tiny smidgeon cooler than yesterday in the end.

This also confirms that today wasn't quite as sunny as it has been in other recent days but today's sunshine totals were still far better than what I was expecting given the amount of high to medium level cloud which was around during the day and so, our exceptionally sunny spring goes on.

Currently around 10°C here in Edinburgh

However, today has started off on a bright and sunny note here without even any of the high to medium cloud which was around yesterday.

Currently around 5°C here in Edinburgh.

There has been the odd forecast which suggests that we could get our first 20+°C maximum of the year today but that is only really an outlier and the general forecast for today is for a maximum of around 18°C which would actually make today slightly cooler than yesterday.

Furthermore, it is also forecast to cloud over this afternoon so today isn't expected to be as sunny overall as other recent days despite the very sunny start to the day.

I noticed that the usual mass of contrails, usually to be found above Chichester, were this morning perhaps 20 miles further west, over Fareham. Were the trails moved that way by high level winds, contributing to your high cloud?

I have no idea David. If I'm up early it's interesting to look at this and see what transAtlantic flights are coming over.

Off topic and nothing to do with high level stuff this Leonardo AW189 from Lee on Solent (see link) came over quite low well lit up a  few minutes ago.

The flight path and activity off the Devon Coast is interesting.

Otherwise a cloudy afternoon with sun shining through the cloud.

The rain further SW is tantalisingly close so the radar suggests. But not for my garden I think.
