*** Forecast are abbreviated today. A weather synopsis / disease development summary follows. Trajectories from the various source areas are given below.
*** Disease Update - 10 August *** First report of blue mold in Connecticut. Jim LaMonia informs us that blue mold was discovered in Hartford County, near the town of Enfield, on August 7. Lesions are one week old or less and there is some fresh sporulation. Your Forecaster has had to spend a substantial amount of time away from his duties recently. County maps will be updated this weekend to reflect the reports we have received during the past several weeks.
Eastern U. S. Weather...... A cold front is draped from the New England coast southwestward into the Deep South. Showers and thunderstorms are likely along and ahead of this front. As this front moves slowly eastward and fizzles... another cold front now in the Great Lakes / Midwest will move rapidly south and east, overtaking the first front and reaching the coastal mid-Atlantic region by Tuesday morning. Behind this second front lies some cooler, drier air. Little in the way of precipitation is expected with this second front. Sunny to partly skies and dry for most areas Tuesday. A chance of showers will continued for areas near the southern mid-Atlantic coast, into the Southeast. Highs in the upper 70's north to 80's and 90's south on Monday, 70's north to 80's elsewhere on Tuesday. Lows in the 60's and 70's.
*** Disease-favorable weather on Monday will be followed by unfavorable weather on Tuesday. *** On Monday.... there is HIGH RISK for all growing regions along the eastern seaboard, plus the southern Appalachian Mountains. There is Low Risk for growing regions in the Ohio Valley. On Tuesday.... the front will have passed most areas. There is Moderate Risk for the coastal plains of VA and the Carolinas. Other regions are at Low Risk. Dry weather should continue on Wednesday for all growing regions.
*** We strongly encourage growers to monitor their plants for signs of disease. Diligent scouting and prompt reporting of blue mold are essential if one wishes to derive maximum benefit from the services we provide. ***

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.
