covered vs uncoveredFig. 1. Danny Van Meter, Clarkson, TN, just sent this photo today showing an area where there was a tear in row during Arctic Clipper in early January. The ryegrass was burned back in uncovered areas of the field as were the strawberry plants. See more photos at the end of this advisory.

Special Weather Advisory on Friday, 1/23/15

Right now all the forecast model are showing a significant cool down early next week in the wake of an  intensifying  coastal storm that will drag some colder air (but not super extreme) down from Canada  the the eastern US Tues into Thursday. We may see low temperatures that are  a few degrees colder than  current models are now forecasting if the low intensifies a bit more than expected.

Here are the AWIS forecasts for next 7 days – again, these could change (and, temperatures go a few degrees lower), if if the low intensifies a bit more than expected.

North Carolina:  AWIS NC Jan 23-30

Minimum temperature maps for Jan 28 and Jan 29:

Wed NC Figure 2. Minimums across NC on Wed 1/28 (this is somewhat different from what was in forecast 2 days ago – see Fig 3)

NC WED Jan 28Figure 3. This was the AWIS Jan 21st forecast for minimums on 1/28. You will note how much colder it will be according to today’s updated map (Fig 2) on 1/28. Before, the “red” areas were confined to upper mountains, and today we see there is red all over (Fig 2).

Thur NCFigure 4. The latest forecast for Thur. 1/29

Virginia

A canopy minimum of 15 is now in forecast for this next Wed morning at this location near Richmond (see map for location of this Skybit).

Wed will be the coldest morning.

Recommendation:  if covers are on, just leave them on  – plus, now its raining in many areas anyway!

Kentucky Grower Report at 12:30 p.m., Friday, Jan. 23 (plants that were uncovered reached 0 F during early January arctic clipper)

close burn

Fig. 9. Exposed area – the plants are more “burned” and will require some added labor for clean-up. I have asked the grower to cut some crowns for us, and perhaps we’ll have a chance to examine those photos in another advisory!
