|---|---|---|---|
| Wed: | WNW / 25 | 14 | BACK FOR ONE NIGHT ONLY! A cold front goes through overnight with a nice rigge of high pressure building behind. Windy (25kts), but hopefully the soaring conditions will make up for that. A trigger temp of 11C reached by 11am gives cumulus base ~3000ft. By midday it should be good enough to make for the wind with good cumulus base ~3500ft. Cold air advection and the air drying out through the afternoon as the ridge does its stuff. Good or very good if it streets. Many thermals broken by the wind, but I'd expect 5-8kts+ in streets. Clodubase getting to 5000ft+ by mid afternoon and possibly to 6000ft late on. I think we will end up with temp/dewp say 15/0 or 14/-1 - something like that. Good for 300km+ for short wings and probably good enough for a 500km+ for big wings. Many areas are good, but I'd probably task up/down wind between, say the Cotswold Edge and Eastbourne. (Yes I know all the best streets will going into airspace!). This is based on the 00Z model run. It might update it again very late this eveing and/or tomorrow morning when Larkhill comes in... |
When the weather gets a bit better - maybe for Thursday or Saturday
