I'm being forced to plant mine today. NOAA is calling for a 40% chance today, 30% for the next few days, 50% Wednesday (night?), and 40% Thursday for the area around our farm. Right now I don't have a choice but to try.
They will come up fine. We've done that before. Once the rain hits it'll be fine.
Don't panic over the turkey yet. If the rain comes soon they won't be able to get all of it. Once upon a time I planted plots and waited over 3 weeks for rain. About 75% of the seed came up.
