FORECAST SUMMARY: Monday, August 27:
*** Forecasts for the 2001 blue mold season will end on August 31 *** Blue mold has been very active this year. Infections have been reported from nearly all growing areas. We will continue to monitor potential transport scenarios, and will report any significant events.
*** Disease Update - 27 August *** Dan Van Hooren in Canada states that he does not foresee blue mold spreading very much this year. Bottom leaves have been harvested on most farms and the remaining leaves are already quite thick. Rainfall has been limited as well.
Eastern U. S. Weather...... Two cold fronts will affect the eastern U.S. Monday and Tuesday. One is moving through the east-coast states today. The other, now in the Midwest, will affect the eastern U.S. on Tuesday. Scattered showers and thunderstorms are expected near the two fronts. Highs will be mostly in the 80's, lows mostly in the 60's.
*** Conditions for disease development will be mixed in most areas early this week *** The most favorable weather will be found in the southern Appalachian Mountains. There is Strongly Moderate Risk for that region Monday and Tuesday. In the Ohio Valley region and southern Ontario..... there is Low Risk today, Moderate Risk on Tuesday. In the upper mid-Atlantic region and the Northeast.... there is Moderate Risk each day. In the lower mid-Atlantic region (Carolinas and VA).... there is Low Risk today, Moderate Risk on Tuesday.

***** NOTE: These forecasts/outlooks only apply to disease development from airborne transport of spores!!! We do not have the capability to ascertain blue mold development by other means, such as transplanting of infected seedlings, nor will we attempt to do so. Please consult the Extension Service personnel in your area if you have concerns about these matters! *****
