We can reschedule session/ place (city) at the discretion of the client or photographer if the appointment day or time booked ends up being a day that it is raining, snowing hailing or for any other unfavorable inclement weather condition that presents itself. We typically use day before /after after the session or  another day and time that works for both the Client and I to reschedule within weeks from the original appointment. There are times when a light snow or light rain can be beautiful for pictures, and in these cases we can discuss if that would be an option for your session.
