It's 95 degrees out and the outside temp sensor says 54 when RL started up middle of day. After about 1 hour of driving the display slowly rises to proper temp. It never took this long before and would show accurate temp reading when first started up. I could have bumped the front bumper on large dirt clods on the job. Nothing appears broken. Typ. scenario.. go to work 6am temp says 64 outside which is about right, get to job day gets into the 90's, RL has been sitting for maybe an hour in sun I start it up and temp says 54 and stays 54 untill i drive home home(about an hour drive) and the temp says up in the 90's as it should. Sound familiar to anyone?

Here's the logic designed into the system. Maybe this will help.

Thanks Speedlever,
This makes sense why the temp ind doesn't go up during the day because on job driving is less than 19mph(unless I get a bug up my ass). However it does not explain why after I get to job( after about 1 hour pluss road/highway speed) temp ind is about right say 60 degrees then after RL may sit for hour then temp sensor says 54 degrees and its close to 65-70 outside and rising. I could have damaged the sensor by hitting clods with the bumper(dirt clods that is). I will keep closer eye on it now that you have given me the logic behind it. Know what to look for.

I've seen this when there is a lot of condensation and/or a trip through the car wash. The sensor gets cooled and insulated by the water that doesn't disperse right away (although your time frames seem extra long)...
