Narrative:

Far part 121 requires an alternate airport to be listed on the flight dispatch release when required by the '1-2-3' rule. I checked the hourly sa report and forecast but did not notice ETA plus 1 hour would put us into the next forecast period, which was forecasting an 800 ft ceiling (altitude required). My dispatcher and myself overlooked this and I took off without the information and had to call en route to have the release amended.
