From BM..
As long as you follow the guidelines provided in my first missive, you should be fine. Wait until the Spring time would be my advice.

Thank you -- so then would painting at 45F from 11am to 2pm, and then the temps dropping down to say 30F by midnight be a problem?
By 11am, I'm assuming all the morning dew is gone. The temps from
11am to 2pm woud be > 40F. By 5pm, sundown, the temps would still be
40F, but then it would drop off and go below freezing by early AM.
Again -- this is just for a few small locations on exterior siding and trim.

Thank you for visiting The Benjamin Moore=AE website.
In general, weather conditions will affect the performance and working qualities of most exterior primers and house paint coatings. Always apply our low temperature paint in fair, dry weather with temperatures between 40 and 90 degrees Fahrenheit. Wait until the morning dew has evaporated and stop painting before evening dampness sets in. Don't paint when it=92s windy or dusty, particularly if you're using a slow- drying, solvent-based paint. All surfaces to be painted should be allowed to thoroughly dry before attempting to paint. After rain, allow 48 hours for the surfaces to dry before applying a paint coating system.
Ambient and surface temperatures, humidity levels and air movement all contribute to the drying of a paint resin. As well, the thickness of the freshly applied paint coating and the porosity of the surface will also have an impact on the amount of time required for an alkyd/oil based paint to set up or dry to touch. The first 4 hours of the dry time is the most critical. Avoid painting in threatening weather=97a shower can ruin a fresh coat of paint. Benjamin Moore=AE recommends waiting until weather conditions improve before you begin painting.
