1500Z: 29009KT 65KM 1CU028 3CU040 7SC050 7.2/-2.0 QFF 1024.5 falling slowly
SYNOP: 42587 72909 10072 21020 40245 58004 878// 333 81828 83840 87650= Beaufort letters (1400-1500Z): cvy Sunny until 0900Z, then cloudy with sunny intervals when a broken layer of Sc spread across. During late morning, some showers were visible a long way out to sea to the SW. Cu hum at two levels; a few puffs of lower based Cu over the sea and more substantial amounts of higher Cu inland making the sky look duller in that direction. It's reasonably bright here under the Sc sheet with breaks to the SE. Excellent visibility. Wind WNW'ly F3. RH 52%. Max temp so far today 7.4 Nigel (Niton, Isle of Wight) 101m amsl |

Max temp so far today 7.4 Nigel (Niton, Isle of Wight) 101m amsl Quite exceptional visibility here in west Cornwall. I posted a pic here. https://groups.google.com/g/weathera.../c/RtC2Ic0iLAY Not enhance in any way, the colour of the sky was just amazing. Also, the prolonged sunshine gave a maximum of 10.0C in Penzance. A perfectly decent afternoon. 0.2mm overnight ruined my run of dry days. Twice that's happened recently. I tried to make it 0.1mm, but I'd have felt guilty. Tinder dry here, I'm going to have to water the front Cornish hedge (wall with plants to the English), everything's wilting. That'll make it rain.

Graham Penzance That's a cracking photo! Stunning blue colour. The visibility late afternoon of the previous day was at least 80km (away from the wintry showers) when I could see Portland Bill to the west and Beacon Hill (North Wessex Downs) to the north reasonably clearly from the top of our local down, both 80km distant. Now that the airflow has backed south of west, we are no longer being plagued by cloud (CuSc) spilling across from the mainland and have enjoyed a sunny day. In the spring, a flow from NW, N or NE often results in sunny mornings but cloudy afternoons. From other directions, the weather locally is often sunnier than forecast. Only a trace of rainfall since 26th March. Nigel |

Only a trace of rainfall since 26th March. Nigel This time of year, being basically surrounded by cold sea, the weather here is often a good deal sunnier than forecast. Even 4 miles NW over the moors at Bosullow, only 1 day since 28th March has failed to record 5 hours of sunshine. See https://www.greatbosullow.net/Graphtext5.png . For this part of the UK the MeteoGroup forecast is a generally lot better than the MetO, which is consistently pessimistic, especially in spring. As you say, typically sunniest when the wind is onshore. Classic case today when I had a walk between Cape Cornwall & Sennen, under unbroken sunshine, whilst there was a fair bit of small Cu, spreading into Sc, just inland. Quite high cloud base for a coastal location. Scilly (30 miles) still very clear, but not the extreme visibility of yesterday. Graham Penzance |
