Storm in Cross Section

This is Crown Copyright so I've trimmed it to make it useless to an aviator, but it is today's storm in cross section, showing "CB" and "TCU" (cumulonimbus and towering cumulus) clouds – thunderstorms, topping at 25,000ft forecast.

The clouds in red are above the freezing level, but thunderstorms are places of severe icing and severe turbulence anyway; aviators avoid them.  The surface wind is forecast to gust to 55 knots around the middle of the day (about 63mph or 101kmh), conditions which are largely unflyable for many aircraft.  The fast jets that I've flown would have been able to take off in that sort of wind, as long as it was down the runway, minimising crosswind, but ejecting would have been very dangerous.  I have taken off in winds gusting to 50kts, in a Jet Provost from Machrihanish, but that was before the ejection seat limit was instituted.  I wouldn't have done it had it not been for the difficulties of staying in that part of the world.  

Not that that is any sort of decent excuse . . .
