Arthur Pic led the way in Formula Renault 3.5 practice at Aragon on Friday, topping both sessions at the Spanish track
The DAMS driver, who went quickest with a 1m40.744s lap in the morning session, came out on top during a late flurry of activity in the afternoon to better that effort by 0.6 seconds.
The second session did not go smoothly for the teams as they tried to gather data ahead of Saturday morning's first qualifying session. A short hailstorm at around the halfway mark led to everybody returning to the pits, and just as more cars were heading back out on track with around 20 minutes remaining, Lucas Foresti brought out the red flag.
Once everyone got back up to speed, it was only in the final four minutes that anyone started to improve on the times they had set before the weather had taken a turn for the worse. Richie Stanaway was heading the times for Lotus at that point, having improved after running second to Pic in the morning session.
While most drivers improved as they put together a sequence of laps for the first time since the early part of the session, Stanaway's time appeared set to survive as the chequered flag came out. But it was then narrowly beaten by Draco's Nico Muller, before Pic made a significant jump to leave his closest pursuers 0.3s adrift.
Robin Frijns (Fortec) managed to sneak between Muller and Stanaway with his final effort, just ahead of team-mate Carlos Huertas, who briefly held the second fastest time during the flurry of changes at the top.
GP2 convert Sam Bird made steady progress over his final short run to end up sixth for ISR, with Walter Grubmuller (P1) and Kevin Korjus (Tech 1) next up.

The 2015 Formula Renault 3.5 season will be notable for being the last with the French company's backing but also produced a worthy champion in Oliver Rowland. PETER MILLS evaluates this year's crop of drivers
Last year's field was extraordinary and hard to match, but the Formula Renault 3.5 grid will still have plenty of talent this season. Glenn Freeman runs through the field ahead of this weekend's season opener
Landing the Fortec seat that took rising star Robin Frijns to the 2012 FR3.5 title was already a good sign for Stoffel Vandoorne. Then McLaren took him under its wing. Peter Mills tells Vandoorne's story so far
