FORECAST DISCUSSION: Tuesday, September 7: *** Announcements *** Beginning Monday, September 6, Blue Mold Forecasts will be produced on Tuesdays and Thursdays. We have a rapidly evolving situation with Downy Mildew on cucurbits, and the Blue Mold disease season is in its latter stages. The forecast staff feels that we can best serve both communities by moving the Downy Mildew forecasts to three times per week while producing Blue Mold forecasts twice per week. As always, additional forecasts will be generated if the situation demands it.
*** HIGH RISK for growers in southern New England Tuesday and Wednesday *** Numerous showers and thunderstorms associated with the remnants of Dennis will affect this region today. Favorable conditions will continue on Wednesday. However, no transport to other growing regions is expected. Elsewhere, the weather will be sunny to partly cloudy and dry Tuesday and Wednesday. Localized disease development is possible in parts of eastern KY and the southern Appalachian Mountains that have received some rain. Otherwise, growers are at Low Risk through Wednesday. TK
