Neither my 'ex' 98.5 2.8 nor my current '02 3.0 exhibited this coolant temp 
behaviour.  The temp gauge reached the mid-point (straight up) even at 
temperatures as low as -40 (C or F, doesn't matter).  The gauge _did_ take 
a while to get there, but it did.  Maybe it's because the V6's generate a 
little more waste heat than the turbo 4's.  The cooling provided by the 
heater core might be more than enough to cool the engine.

Yes, I think that the 'snowflake' temperature range is described in the 
Owner Manual.
