Week beginning Monday 18th March

Postby Dave Thomas » Sat Mar 16, 2019 8:51 am

Early indications are still that this week is going to have some flyable weather for both HG and PG.

Monday is swapping about quite a bit, but with post cold frontal NW winds of somewhere between ideal and a bit too strong, there's a good chance of launching. We may or may not be in the good air - the forecasts are varying about a lot over the UK with relatively small areas having really good conditions, so it will have to be the morning RASP update on Monday to see what's looking likely - however that's not necessarily going to stop it being flyable, just not perfect. If it's windy-ish my preferred choice would be Long Mountain, but at present everything is suggesting it might be more west than NNW, and that makes it more difficult except for HG's.


Tuesday onwards, the winds switch to south of west generally and though rasp is not showing a star rating I think it's more likely to have periods of nicely flyable air at the Mynd or our SW facing sites, I think generally better conditions for most pilots to have some spring fun. Having said that, there a multiple bands of cold, warm, occluded front's out in the Atlantic due to come across the UK, so it all may change massively, but I'm basing things on my impression that the forecasts have been above average constant for this period rather than swapping about much.

Monday is looking pretty well not far off west at the Long Mynd, forecast winds are between ok for PG and HG or the higher forecasts give it unlaunchable for PG's . What does seem to be agreed on is that it will start off looking promising with sunshine but then cloud over and deteriorate a little bit - a collapsing occluded front passing through, though as long as it's not too windy should still be soarable. The Synoptic charts I've seen don't detail exactly when and where this front will fade into a trough but at present is due sometime in the day passing through.
Elsewhere the air is due to be better further into SE England (but not entirely due to that trough), but due to the wind speed site choices are limited - much more NW direction down that way.

Monday now looking rather disappointing. Wind bang on for the Mynd, but probably too strong for PG's and the cloudbase is due to be low and decreasing. By mid afternoon barely above the hill height. Go early for the best chance of flying I'd say. Careful if flying under heavy layer cloud as embedded towering Cu to 10000ft are forecast.

Elsewhere not a great deal better really, though winds are due to be a tiny bit lighter further south and the hills not as high.

Tuesday onwards the winds are very roughly similar sorts of speeds (probably slightly too much for many) gradually backing to the south west. End of the week things are due to change, but not necessarily for the better.

Tuesday - Currently the webcams show it being much better than the forecasts, which should have the hill in cloud. The wind is west on the mynd at present, but it is due to go off towards the SW, and the air is due to be better further west anyway, so if it does go too far off, might be worth a trip to clatter/shepherds tump.

Wednesday, supposed to be WSW most of the day, so Mynd might work for ridge soaring, though not ideal. Wind speeds should be ok for PG and HG but are due to increase in the afternoon so might get a bit strong then. Inversion level is low, barely 2000ft ASL, but due to be dry, with the current low cloud due to rise well above the hills. There is due to be a large patch of better less cloudy air between the Mynd and into the Peak district, so the options I think are Long Mynd or in the Derbyshire Dales or Peak district, elsewhere is even lower cloudbase.

Weekend, forecasts all over the place and swapping about, but probably a lot better than during this week.

Wednesday turned out roughly as suggested, though only Black knoll was soared most of the afternoon I think, the Long Mynd launch was always too far off to the south until it got too strong to launch. Derbyshore peaks had good soaring and thermalling.

Thursday looks like being somewhat similar direction but forecasts vary between hardly any wind and just about nicely soarable. All depends if it's got enough west in it today - but it's going to be cloudy with a very low base.
Friday blown out
Saturday good
Sunday good
