The Walla Walla, Washington (the name means "Place of Many Waters") high temperature forecast on Thursday looks like another case of the two main U.S. models disagreeing. This time it seems that the NAM has much more cloud cover than the GFS Thursday afternoon, resulting in a 15 F difference. So let's forecast Tmax and see which model is better in this case.
