THIS IS A TEMPORARY FORMAT FOR NOW
Last update: 10:30 20/05/2022 (21 hours ago)
High pressure building from the south for the weekend. Lower pressure for Monday to Wedneday, but then high pressure trying to build again towards the start of the regionals (possibly).
| Day | Wind Dir / kts |
Tmax / °C |
Description |
|---|---|---|---|
| Fri: | WSW / 20 | 15 | A small low and trough causes some bad weather in the southeast. We miss the worst of that, but get lots of cloud. In the afternoon it might be vaguelly soarable for a bit, but with 7-8/8s CuSc 2000-2500/10000ft some showers and then the wind picking up to 25kts+ |
| Sat: | WSW / 13 | 17 | Rather a lot of top cover at 20,000ft+ all day which slows the heating and dampens everything down a bit, but the air is ok with a roughly isothermal layer from 3-7,000ft. A trigger temp of 15C gives shallow cu base 2500-3000ft by 11am(?). In the afternoon reasonable conditions with good cumulus base 4000ft+. In fact good cumulus base 4000-4500ft+ ASL over much of England and Wales away from the windward coasts. Good for 300-500km? |
| Sun: | SSW / 7 | 19 | At Lasham soarable by 11am(?). In the afternoon either shallow cu base 3500ft+ or blue to 4000ft+ or a mix of both with ittending to blue out more as the afternoon goes on. Inland (say north of the M4) better cumulus base 4000ft+, but also the risk of some medium cover north of 52N. Good for 200-300km+? |
I will maintain the outlook every couple of days until the weather improves and there is a good day coming up
