Evaluating Frost Risk in Your Area (10:30am, Sun, 3/20/16)
Dear Agents, Agronomists and Growers,
Temperatures will definitely be low enough for frost to occur on Monday morning across most of North Carolina, but the forecast has changed somewhat since yesterday, and due to winds and/or lower dewpoints, many areas that were suppose to have frost on Monday (like Raleigh-Durham) may NOT see frost until Tuesday morning.
Fig. 1. Minimum temps on Monday morning will near freezing in the piedmont, and sub-freezing in western areas. However, frost may not occur due to high winds and lower dewpoints. Conditions will change Monday night/Tuesday morning, and widespread frost is anticipated. A frost during bloom stage of strawberry can be very damaging. In the absence of frost, the strawberry open blossom “can handle” minimum temperatures down to 28 F.
Figure 2. Minimum temp map for Tuesday morning is not that different than Monday’s minimum temp map, but FROST is definitely expected across most of the state on Tuesday due to very low winds and dewpoints that will be closer to 32 F.
