Narrative:
I reviewed our WX package for flight sdf to jax may/wed/98. Jax was forecast temperature 2 mi 008 broken. We had mco as our only alternate. The problem arose in-flight as I was speaking with our dispatch on the radio (phone patch) and he informed me that our alternate (mco) was forecast 1/2 mi for our time frame. I looked at my WX package again and figured out that we had 2 mco forecasts, I read and underlined (mco) forecast for our time frame of better than 500 ft 1 1/4 mi. I accidentally overlooked the amended forecast which was for 1/2 mi. I think this would have been avoided if our dispatch would only include the most recent forecast on our paperwork. We got a new alternate and we landed at our original destination (jax) uneventfully. I also think my dispatcher for our flight missed the mco forecast (1/2 mi) for the same reason.

Narrative: I REVIEWED OUR WX PACKAGE FOR FLT SDF TO JAX MAY/WED/98. JAX WAS FORECAST TEMP 2 MI 008 BROKEN. WE HAD MCO AS OUR ONLY ALTERNATE. THE PROB AROSE INFLT AS I WAS SPEAKING WITH OUR DISPATCH ON THE RADIO (PHONE PATCH) AND HE INFORMED ME THAT OUR ALTERNATE (MCO) WAS FORECAST 1/2 MI FOR OUR TIME FRAME. I LOOKED AT MY WX PACKAGE AGAIN AND FIGURED OUT THAT WE HAD 2 MCO FORECASTS, I READ AND UNDERLINED (MCO) FORECAST FOR OUR TIME FRAME OF BETTER THAN 500 FT 1 1/4 MI. I ACCIDENTALLY OVERLOOKED THE AMENDED FORECAST WHICH WAS FOR 1/2 MI. I THINK THIS WOULD HAVE BEEN AVOIDED IF OUR DISPATCH WOULD ONLY INCLUDE THE MOST RECENT FORECAST ON OUR PAPERWORK. WE GOT A NEW ALTERNATE AND WE LANDED AT OUR ORIGINAL DEST (JAX) UNEVENTFULLY. I ALSO THINK MY DISPATCHER FOR OUR FLT MISSED THE MCO FORECAST (1/2 MI) FOR THE SAME REASON.
