One hour after the primer is dry to the touch, light rain should not be able to penetrate the primer. The primer of an exterior paint job needs to be dry before a heavy rain or it may wash off. If it does rain before the primer is dry you will need to wait for the rain to stop, scuff the area, sand it down, and prime it once again.
An oil based primer will take a little longer to fully dry but can handle rain. If the the substrate is dry when the primer is applied then rain should not effect it 30 to 60 minutes after you apply it.
Rain will slow the process of drying and might change the appearance, but it should not affect the quality of surface bonding. In order to prolong the life of your exterior paint job, it would be best for you to have a general sense of how long it takes for paint to dry.
Predicting the drying time for exterior latex paint is difficult as there are many factors. There are general rules for estimating how long your fresh paint job should last before it becomes damaged as a result of exposure to rain.

Is the outside temperature below the minimum recommendation as specified on the paint can? Temperature and moisture work in conjunction with each other. The lower the temperature, the longer it will take for your exterior surface to dry. Some paints can be applied in temperatures as low as 34 degrees Fahrenheit.
But always think ahead, check the weather report, and give yourself a buffer zone. For example, if you are painting at exactly 34 degrees in mid-morning and you expect it to hit freezing later in the day, you are unreasonably pushing the envelope. Will temperatures drop below minimums? Do not paint if the prediction is for temperatures to drop below the minimum within 10 hours of the paint application.
Check the paint can label for the temperature recommendations. It is difficult to fix a painted surface that has not yet cured but that has been rained on. The water forms rivulets down the painted surface, affecting both the paint color and its texture.
The best way to fix this is to wait until the paint has fully dried. Next, cut away the raised lines of paint with a straight-edge razor. The affected area may need light sanding. After you have smoothed the surface back down again, the surface must be re-painted.

After it rains, we typically wait a couple of days to make sure that the siding is perfectly dry. Fall and spring can also both offer wild fluctuations in temperature, especially as the sun dips down after a warm day and the air quickly cools.
With this in mind, we typically wait a couple of hours after dew point to start painting again, just to provide ample time for your outdoor surfaces to dry before we resume our work.
