[Thundery wintry showers]

Dry and cloudy at Cleadon with 8/8 cover of stratocumulus trapped underneath the inversion. 8.0C following a minimum of 7.0C. There were some sunny intervals yesterday but it progressively clouded over as the day went on, leaving the full cloud cover today.

[Bottesford]

Low cloud - yuck! Seems thicker today and sun struggling to burn it off.

Currently 9.4c.

[johnholmes]

The visual sat picc and the latest temperatures show the situation today.

The sat picc has some holes in it but nowhere near as extensive as by mid morning yesterday. Temperatures are pretty much all below 10C, many 9C or below with the StSc sheet. Little chance of it breaking from above for many but those near the clearer edges, see the sat picc from Dundee (visual), for those most likely.

The fog was so dense at 21.00 last night that we couldn't see our neighbours' garages 20 metres away!!

It was still foggy at first light this morning and is still foggy, though less so, now.

Flat calm, 8.6c after 5.2c minimum.

[Zenarcher]

Today I noticed the first leafs are growing on the trees today a sign of spring. Today its mainly cloudy with some breaks in the cloud and the sun is trying to make an appearance but I don't think it will. Temp 9.5c and wind 16mph.

[Terminal Moraine]

After a cloudy morning a hole has developed in the cloud sheet right over the Peak District and it's currently clear and sunny.

Despite the sunshine it's much cooler than yesterday with the temperature standing at 8.8c.

After a cloudy morning a hole has developed in the cloud sheet right over the Peak District and it's currently clear and sunny.

Despite the sunshine it's much cooler than yesterday with the temperature standing at 8.8c.

yes the visual sat picc shows up the break quite nicely, reports show Woodford has SCT but Manchester shows BKN so its a pretty clear edge, your report ties in nicely; here the first glimmer of sun through the StSc sheet about 10 mins ago and the cloud shows movement from about W or WNW, so areas ESE of your area are probably best placed to get any breaks extending from the area over yourself.

looking more closely at the 00z Watnal, the cloud is about 1,000ft+ thick, so 11C is needed to start to break it in situ rather than the break which is showing over the Peak. This probably partly occurring through some overturning just below the inversion height aided by the topography.

Trying to forecast this sort of thing is hellish difficult. The broad brush treatment is the only way=mostly overcast at first but some breaks developing around lunchtime but areas of low cloud rather persistent in places!

Vague but about the most sensible way of dealing with it until breaks start to show then mesoscale use of wind profiles and observations will help get more accuracy.

After another foggy night it's just a sheet of stratus murk now with no signs of breaking for the 3rd day running, currently 8.5c after a low of 7c.

[James M]

Lovely sunny day today! does feel a little cooler though

[Scorcher]

Have to say I am not enjoying this current spell, I usually enjoy high pressure but not murky highs like this one. In all honesty anything would be an improvement, there's nothing more frustrating than believing you are going to get warm sunshine and then being greeted in the morning by low cloud and spending all day willing it burn off.

[johnholmes]

temperature is up to 10.3C and the cloud is now showing much better signs of breaking, whether that is the temperature inducing it or the clearer slot moving in I'm not sure.

[Frank Trough]

cloud has broken here in North Hants in the last hour.

[johnholmes]

tempo breaks to 4/8 shallow low CuSc but no total blue sky like the last day or two-max looks like being 11.C, its now 10.6C

[Weather-history]

After a very cloudy day yesterday, the cloud broke with ease today and has turned out a very sunny mid to late pm
