Oil weight question and cold weather

Allen,

We are right next door in Indiana and run Areoshell 15W50 all year long.
If it's working for ya why change!! The 40's and 50's ain't ****... You
California boys can't handle a little cool weather huh? :-) See ya!!

I run aeroshell 15W50 in my lycoming 360 AK4 engine.

I am planning a trip to Ohio the second week of November where the weather
forecast is for upper 40s low 50's during the day and 30's at night. I
plan to say a week.

Do I need to adjust my oil accordingly, like get an oil change with a
different viscosity b4 departing?

Thanx in advance.

Allen
