Weather man says 80% chance. Man on the radio say 100% of us do not believe it.
The winds have shifted and no matter what take precautions to protect your spring plantings.
Cold winds can do alot of damage to young tomato plants. Local weather says we will see mid-40's tonight. The temperatures alone will set back their production. Get some sort of structure with covering around the plants to protect them from the breeze.
If it were me, I would keep them covered each night until the temps get back up into the 50's.
On this date in 1948 it was 21 degrees in San Antonio.
