ALERT: It’s going to be very cold on BOTH Jan 7th & Jan 8th. Growers who elect to pull row covers back on, should do so as soon as field conditions allow. Right now it is raining again in many areas (even thundering), so it could be as late as Tuesday before covers are dry enough to be pulled? Today (Sunday) we nearly reached 70 F in Central NC. Temperatures could drop by more than 50-55 F this week – the expected minimum at Clayton Central Crops on Thursday morning is 16 F, and Friday 15 F.
This advisory provides more detailed information for SC, NC, VA, TN, GA, KY and MD.
I received a message last evening from Eric Hunter in foothills of SC, and Eric said he is now anticipating a low of 5 F on Wed night/Thur morning (Easley, SC). Clemson is not that far from Easley, and I noted that Clemson may now have a low of 12 F on Thur morning.
Clayton – we’ve seen quite a drop in the canopy min temp forecast:
In Table 1 you can see that back on Jan 1st the forecast for Jan 8th was for a minimum of 28 F. On Jan 2nd the forecast changed to 19 minimum in the canopy (SkyBit). Yesterday, the forecast changed again! The minimum being projected on Jan 3rd for Jan 8th was 16 F. Last evening’s forecast also indicated that the minimum on Jan 9th could be 17 F.

If this downward trend continues, it may be that the Clayton area could see minimums in the low teens on both Thur and Friday.
At 2 p.m. today, it was 68 F at Clayton. Assuming this is the high for the week, we will potentially see a drop in temperature of from 50-55 degrees between today and Wed night/Thur morning.
At Clayton, winds may be at their lowest tomorrow (Monday: N-2 mph and gusting to 5 mph). Then, winds will be more of a problem Tuesday (SW-8, G 16).
Dewpoints will be down in the single digits by early Wed afternoon, and may drop into negative territory that evening. Winds will likely be in excess of 10 mph by as early as 9 a.m. on Wed at Clayton. To pull a cover on at this location, it should be done Monday, or Tuesday at latest.

Editor’s note: This would be a good time to check your instrumentation for monitoring temperatures in the field next week! I would appreciate getting some field temperature data next week showing contrast of temperatures under the cover vs. outside.
p.s. Just got a very nice pledge from Whitted Bowers Farm in Cedar Grove, NC for $350 (that’s awesome). Earlier today got a nice pledge from Rudd Farms as well. That brings us to $5,500 (enough to cover the weather services costs for this advisory). Hoping to see some industry support this week.
