Race day at Silverstone began dry and bright - and with Jorge Lorenzo leading the morning warm-up for the British MotoGP.
Temperatures were still cool (air 15-degrees), and the ever present wind on the former airfield continues to torment the riders, whilst ushering in a constant stream of clouds across the otherwise blue sky.
That in turn means the threat of rain is never far away.
Fourth in Saturday's rain-interrupted qualifying, 2012 title leader Lorenzo led his first track session of the weekend by lapping 0.219s ahead of Ducati's Nicky Hayden on the fourth of his ten laps. Hayden will start seventh after a fall in the closing stages of qualifying.
Honda's world champion Casey Stoner lapped 0.290s from the front in third, where he will start the race.
Yamaha riders Ben Spies (Factory) and Andrea Dovizioso (Tech 3) were fourth and fifth this morning, while debut pole sitter Alvaro Bautista set the sixth best time for Gresini Honda (+0.766s).
Hector Barbera (Pramac) and Stefan Bradl (LCR) were the final riders within a second of Lorenzo, with Hayden's team-mate Valentino Rossi left in ninth place - but almost one-second under his qualifying time.
Just 0.3s behind Rossi and 1.3s from Lorenzo was the returning Cal Crutchlow, cheered all around the circuit by the British fans.
The Yamaha Tech 3 rider missed qualifying for his home round after injuring his ankle in a Saturday morning fall.
The team reported that hospital scans failed to find any fractures, and Crutchlow passed a medical check this morning, but the Englishman himself says he has "a broken and dislocated left ankle".
Crutchlow, who missed last year's British race due to a broken collarbone in qualifying, went steadily faster as the session went on, eventually setting the tenth best lap out of the 20 riders – ahead of Repsol Honda's Dani Pedrosa.
Crutchlow's best lap time, of 2m 4.999s, would have put him ninth on the grid in qualifying. Instead, Crutchlow will start last, but clearly has the potential to beat the CRTs at the very least, which would mean eleventh or better.
While Crutchlow rebuilt his confidence, countryman James Ellison suffered a highside from his PBM Aprilia at the end of the session and limped away with the help of marshals.
