True.

This doesn't in any way, change the length of the actual official observation day as that always begins and ends at 09:00 UTC on every morning  but the change of the clocks to British Summer Time does mean that according to our clocks and watches, the start and end of each official observation day  now happens an hour earlier as this is now happening at 10am BST every morning instead of 9am GMT (both of those times convert to 09:00 UTC).

Rather unusually for this spring through (although this month has been much wetter here than the same month last year), today has started off on a rather dull, wet and miserable note here in Edinburgh and it is also fairly windy.

This rain is expected to clear away fairly quickly during the course of the day though so even with that, I'm sure that the Sun will still be out later on as per usual. Once that happens, I will then be looking to those much later sunset times which will now occur as a result of the change of the clocks.

Last night was fairly mild as well although the temperature here in Edinburgh is currently only around 6°C as I write.

The main rain area has now cleared away but after a brighter and sunnier spell of weather, frequent blustery showers are now feeding in through the Forth-Clyde Valley towards here with the wind gusting up to around 48 mph the WSW.

The rain has been almost torrential here at times with some fairly intense echoes showing up on the latest radar maps and I'm pretty sure that I even heard a rumble of thunder in the distance a short while ago.

Today is still slightly warmer than of late though, currently around 11°C here in Edinburgh.

EDIT:

That earlier rumble of thunder is now showing up as a lightning strike on the latest maps, not all that far to our WNW.

In addition to all of that, there has just been some hailstones mixed in with this latest shower and I could even hear that as well.

In this and other threads, you have talked about this month being drier than average where you are despite Edinburgh Gogarbank being slightly wetter than average but given these latest conditions, I will be very surprised if that is still actually the case even now.

Furthermore, colder air has now started to dig in and although the temperature here in Edinburgh is still at around 7°C as I write, it now feels much colder than it did earlier on. The radar maps are showing that the showers are gradually turning to sleet and snow in the highlands and parts of the Southern Uplands as that colder air digs in, so it might not be too long before we possibly start to see a bit of that in the Pentland Hills to my south as well.

A comedown on yesterday's strong sunshine and convective cloudscapes.

The Pentland Hills to my south continue to remain completely green and there wasn't even any ground frost as the overnight temperature at Edinburgh Gogarbank only dropped to 3.2°C although even that is still fairly chilly for this time of the year.

The wind has died down though and the usual sunshine is back once again.

Currently around 5°C here in Edinburgh.

The day has started on a mostly cloudy note with only the odd occasional bright or sunny interval at times.

In addition to that, there is also some very light drizzly rain around at times which isn't even showing up on the latest radar maps, but which is making it rather damp at times.

However, it's a lot milder than of late this morning with the temperature here in Edinburgh already at around 11°C.

A bit uninspiring, it has to be said but could be worse. It snowed on this day in 2022. 😁

20.5C ao far.

Managed 21C making it the warmest day so far this year here.
