FORECAST DISCUSSION: Monday, July 21, 1997 - *** A period of disease-favorable weather will plague the growing areas this week. *** Warm, moist air.....an almost stationary front in the mid-Atlantic and upper Ohio Valley....and the remnants of hurricane Danny will combine to produce conditions favorable for blue mold development this week. Growers can expect more general cloud cover and good chances of showers or t'storms for at least the next several days. Revitalization of low-activity sources should be anticipated and localized development near fields with blue mold "hot spots" is quite possible.

Sources in the southern Appalachian Mountains, southeast PA, and Connecticut are SERIOUS Threats today and Tuesday. All the other sources are Moderate Threats. Growers in the southern Appalachian Mountains face a Strongly Moderate Risk situation today, jumping to a HIGH RISK situation for Tuesday. Growers in SE Pennsylvania are at Moderate Risk today and also go to HIGH RISK for Tuesday. Connecticut area farms are at HIGH RISK on both days. All the following areas are at Moderate Risk today and Tuesday: NC, VA, MD, WV, KY, central and E TN, and southern sections of IN, IL, and OH. As mentioned before, growers in the mountain regions of these states progress to a HIGH RISK situation on Tuesday. Conditions will remain favorable for a while, so expect more elevated risk assessments on Wednesday. TK
