Morning Update on Freeze and VA, NC, GA, SC AWIS Temps (7am, 1/19/16)
Dear Growers, Agents, Agronomists & Others,
At 6 a.m. Clayton registered 19 F, and then it reached 18.7 F at 8:10 a.m. Dewpoint went negative this morning (see graph below).
SkyBit Forecast is very close!
The Clayton SkyBit forecast was for 11 in canopy this morning with air temp outside canopy at weather shelter of 17 F. At 8:05 a.m. it was 18.7 F at weather shelter, so this is pretty accurate forecast (actual temp is about 1.7 F higher). But, what everyone should appreciate about this product is that it gives you information about the temperature at the strawberry canopy level height, and it was 6 F lower this morning. That is a considerable difference from temperature at weather shelter height (around 6 ft) and ground level. It is very explainable by the fact that there is really no moisture in air today! Solid objects (including a strawberry plant) at ground level give up their heat very very rapidly under these conditions.
Good news on SkyBit offering in 2016:
I got the go ahead to offer SkyBit E-Weather Strawberry Canopy Forecast again this season, and if you were one of the subscribers last year, I will be contacting you tomorrow or the next day about getting it started up again for 3 month period (most growers want it from mid Feb to mid May). For other growers who have never used this product, I will be providing details this Friday on how you can subscribe.
Pledges needed to fund this advisory:
This Friday I will also provide information on how you can support this advisory service in 2016. Your support is definitely needed!
