- Depending on workload, will try to do outlook and soaring foreacast for most XC-able days
THIS IS A TEMPORARY FORMAT FOR NOW
High pressure tryA transient high pressure Fri-Sat, but then it is poorer again for a few days.
Thu : High pressure trying to build from the south and out to the west, but still cyclonic over the UK with a weak slow moving occluded front and troughs moving from NW to SE. Wind 260/15kts -> 260/20kts. Soarable to some extent most of the day with large lingering cumulus base 1500-2000ft+ by 10am. Bases rise to 3000ft+ by early afternoon, still with large lingering cumulus with tops going to 8-9,000ft. Tending to overdevelop and getting later in the afternoon. We'll see how much cloud there is tomorrow, but hopefully good enough for a short XC 100-200km+.
Fri : Amazing - a ridge of high pressure over the UK. Wind W-WNW/1-12kts, cumulus base 2500ft+ by 10am. By early afternoon quite a lot (4-6/8s) lingering cumulus base 3000-3500ft under an inversion at ~5000ft. Bases rise to 3500ft+ with tops to ~6000ft. Some areas with better conditions eg: E.Midlands with good cu base 4000-4500ft+ (but that might be too far for use to go from Lasham?). Should be good 200-300km+, possibly 300-500km???
Sat : The ridge collapses with low developing well to the SW and the high pressure moving off to the NE. Wind ESE/8-10kts. Variable conditions from area to area, but typically too much cloud (5-7/8s) cumulus base 3000-3500ft+ under a lid at ~6000ft which tends to get cloudier through the afternoon. Another wait-and-see, but hopefully good for 200-300km+...
Sun : Warmer, wind E-ENE/20-22kts, a low inversion to heat out through the morning. Maybe a bit of soaring mid-late afternoon when temps get to 22C+ with cumulus base 3000ft+ under rather a lot of top cover.
Thursday evening for Friday.
