From a very dark and gloomy Haytor (home of the raindrop),


.... if anyone is going to get a 'good old blow' it should be you Will! A
good test for the new equipment.

GFS is suggesting 80Kt convective gusts just off the SW

At upland locations or where lee-wave motion
plays a part, and where instability breaks across the zone of strongest
gradient (dry air intrusion aloft ... as pointed out by David), then
such gusts could occur ... indeed, given *vigorous* instability,
free-air at even higher levels can be brought down to the surface in
isolated spots. This is why warnings etc., are so difficult to write in
these situations - v

Camborne and (and Watnall) soundings at 12Z show the dry air intrusion down to very low levels-

The Aberystwyth profiler shows the jet,disturbances in the tropopause and slantwise and vertical
(convective) circulations at lower levels (i think-have no expertise at interpreting these)

I saw a gust from Plymouth of 44 knots (9 group in synop) which is 52 mph
not 50 mph ???

My max was 30 knots (36 mph). But then I get a lot of shelter from the SW
despite altitude.

Highest gust I recorded on Saturday was 33kt (38mph) but
this was beaten on both Friday with 38kt (44mph) and today,
just an hour ago with a 35kt gust (40mph) during an intense
rain shower that dropped 5.8mm in just 15 minutes.
