Potential for Frost Damage in April — Unlikely
The long-range low temperature forecast through April has no temperatures predicted below 32 degrees F. The frost freeze guide predicts that most Missouri counties have less than a 50 percent chance of temperatures below 32 degrees after April 15 (Figure 3). At this point in the season below 32 degree temperatures are unlikely through the end of April.
Figure 3. After April 15, there is a 50% chance that temperatures will be ≤ 32 degrees F. For more information on frost freeze dates, see Missouri Frost/Freeze Probabilities Guide. Image credit: Pat Guinan, MU Extension Professor of Climatology
