Evening Frost Check for Foothills and Mountains of NC (5:44pm, Wed. April 9, 2014)

— Written By Barclay Poling

7daytemp.nc.2Fig. 1. The minimum temp map for NC on Thur morning – very little change from yesterday’s forecast (see Fig 2). I would definitely set a frost alarm in the light blue (38-40) for 38 F. A frost could easily occur under the light wind to no wind condtions tonight. Start sprinkling at first sight of ice crystals forming in lowest section of the field on ground vegetation, rolled up row coves and lay flay line.

p.s. if we do get a frost in Kinston tonight (very doubtful), we’ll be ready! We just installed this today.

Fig. 2. This low tunnel has been installed for a “rain protection” experiment this spring, but it can be very effective for protection against frost as well.
