Warming up Spyder for oil level check

[teninospyder]

Weather not cooperating
Just DIY'd changed oil/filter/HCM filter, etc. for first time on my own
Added oil and want to check level. Can't run Spyder in garage (part of house).
Pouring down rain outside, and "cool" -
Real experience if any, please. Can you realistically expect the spyder system to warm up on it's own, if you start it and let it idle under carport in 40+ outside temp for a long (how long?) time??

UPDATE : Let Spyder sit outside running just now for 20 minutes in 40 degree moist air. The Oil Warning light went out as it should.
Took it for a ride on street outside house. Shifted thru gears up and down. Seemed to be much "softer" than before the oil and filter changes. Took it out on "local highway section" for 2-3 miles of normal up down shifting. Everything appears to be OK ! Brought it home and checked oil PER PROCEDURE. Oil Level is "right at" the upper bubble on the dipstick, but I don't think "over". Will keep an eye on it.

Thanks to all who helped me out on this.
