Silverstone forecast doesn't look great for us (no surprise there). While it can always change the day before, 91% is a pretty damning prediction and would track for the UK. (And yes, the rain is predicted for daytime, not night.) Even if it doesn't rain over the track, we're just going back to our cold tire issue. I didn't expect anything less from Silverstone of all places but it's still frustrating.
Worst case scenario would be if it rains on Friday and then not on Saturday and Sunday, making the first 2 FP sessions less helpful in evaluating the new "upgrades" for the weekend. We saw how Leclerc struggled a bit to make back the Friday sessions he essentially missed in Barcelona, we don't need a repeat.
BTW, not saying this because I'm worried about our GP placement (I'm starting to become numb to races lol), just that cold, rainy weather is not the most representative baseline in seeing how the new spec performs and might hamper finding the correct setup, which naturally would be helpful for future races as well.
