FORECAST DISCUSSION: Friday, June 25: *** Blue Mold Update *** Paul Shoemaker informs us that blue mold has been discovered in Buncombe County and Yancey County in the central NC mountains. Both these sites are near the current source in Madison County. Blue mold is active at these sites and conditions in the mountains remain favorable. Bill Nesmith in Kentucky informs us that the outbreak in Shelby County, KY is under control due to agressive action by the lead farmer. This source is being removed from the forecasts. BRAVO ZULU to this grower !!
*** Favorable weather will continue through the weekend. *** Conditions will vary day-to-day in most areas. However, most growers will face Moderate Risk or better on at least 2 out of the 3 days. Growers in the southern Appalachian Mountains will be at HIGH RISK each day. This includes an area from southern West Virginia southward to the NC/GA border. Growers in south-central Virginia.....central and eastern NC....and eastern SC will be at Moderate to Strongly Moderate Risk each day. There is Strongly Moderate Risk for growers in southern GA and northern FL each day. Growers in southern Ohio, western WV, eastern and central KY, and north-central TN will be at Moderate Risk each day. Finally, western KY and southern Indiana will be at Moderate Risk on Saturday. TK
