19 C here in the southside, 18 C Gogarbank, 16 C at the airport and maybe less at the Botanic Gardens?

Largely cloudy this morning as an area of heavy rain pushes in from the east with thunder likely for many. In the afternoon, the rain will clear to heavy, thundery showers, most easing by evening.

Met Office - Dorset Snow Centre

Morning fog patches will soon clear to leave bright day with plenty of sunny spells. However, scattered showers will form by the afternoon, some heavy with hail and thunder, especially in the east. A warm and humid day. Maximum temperature 18 °C.

Which is to be?

So far it is a beautiful bright morning with some early sunshine and a temp of 12C. Flat calm.

Looking at the radar there is a large blob of rain in NW France. Even some lightning near Lille.

TBH I'm not sure what to expect. For an alternate take, I'm sure I can find an Express headline assuring me that a killer heatwave with 200 mile wall of now is on offer. One of those days I need to watch the radar.

Similar for here: last night the forecast was predicting thundery rain to move in from the continent this morning.  When I checked the automated MetO forecast it shows dry until mid morning then light rain - but the rainfall radar shows a large area of rain about to arrive with heavy stuff mixed in - and the 0757 radio forecast said rain for much of the day!

Currently very murky and dull

I think something overnight going on in the atmosphere has confused their forecasts.

Just back from Weymouth. I left in fog drove over the Ridgeway to find Weymouth under sunshine and a glorious morning.

Back over the hill and it's lifted fog. All over the place the weather today. The radar shows rain to the east in a sort of stretched line before the large mass further east. No wind which is good.

I'm actually west of you David.

A small red blob moving my way might be one of those fabled thunderstorms forming.

Watching the radar and getting ready to bring in the laundry.

When I looked at the radar at 10, I was sure of some rain by 11, but since then the bands seems to be splitting and disintegrating along the line of the M4. Might get some in an hour but not counting on it just yet.

This Spring is being like an engine of one of my past Ford cars, struggling to start up and when it does finally roar into life it stalls and takes ages to start up again. 

Showers to the north.

Today's high so far is 20.9, following on from an overnight low of 8.2. Yesterday's high was 19.4.

(And the 91-20 average mid-May max is 17.3)

It's quite late in main sea fog season for it to be so determined to completely blank out the whole area for miles inland and very little wind actually pushing it in.

It has developed considerably in the past three or so hours.
