Collapse ▲Good evening,
There was a serious frost this morning in many areas of the state that “just sort of snuck up on us,” as John Gross (Sanford) said to me this morning. Growers who removed row covers yesterday morning (Friday) to get the crop “opened up” for pollination purposes — had to run sprinkler irrigation systems this morning. Up here in Williamsburg, VA (where I live), we had a tremendous frost this morning (got to 26 F).
NC Risk for Frost on Sunday morning??
It does not appear that there is any great frost risk for Sunday morning across the state, but in some areas where you see those powder blue (38-40) and teal bands (36-38), I might be inclined to do a“a little wandering around in the field in the early morning to see what is really going on (Scot Luton, Roper, NC).”
Fig. 1. Minimum temperatures for NC on Sunday morning
In examining some locations in the “Inner Banks” region of NC, like Ahoskie, Ahoskie Sunday morning you can see the minimum is expected to be 38 with OVC skies (overcast), but if skies were to clear in the early morning, and winds drop just a little bit, guess what might happen in some of those “cold pockets”?
Sunday night/Monday morning
Looking ahead to Sunday night/Monday morning, the probability of frost is much greater in Ahoskie/Edenton areas as skies will be clear, and winds in 0-1 mph range. With a dew point of 32 F on Monday morning these are near about perfect radiation frost conditions.
Every area of the state is different, and you will want to do some advance FROST planning for what is ahead in your area this week. And, please note that there is going to be risk of frost right into next Friday morning. Here are the minimum temperature state maps for Monday – Saturday, and FRIDAY MORNING is looking like the coldest morning of the week.
How is the crop advancing in different areas?
Up here in VA where I now live, we have a very cold week on tap this week, and we are still a good ways off from the start of the season. However, I received these 2 photos of Merced today from a southeastern NC grower!
Figs. 2 and 3. This is Merced in Southeastern NC (near Wilmington) on March 17th
And, I asked Clyde Gurosik, N. Augusta, SC, if he could share with us his season starting dates for the last 5 years (last year was super early). His goal is to be open 3/23 this year.
Dr. Poling,
Here is the data requested:
3/23/18 GOAL
3/18/17 all 6 markets, some by 3/1/17
4/2/16
4/11/15
4/7/14
4/3/13
3/31/12
Bet if I go to the history files, available thru www.weather.uga.edu, there will be some correlations.
