*** Mixed to mostly favorable weather in the Ohio Valley and the southern Appalachian Mountains Monday and Tuesday *** Hot, humid air sits over the eastern United States. A stationary front lies over the mid-Atlantic and Ohio Valley regions. As this front dissipates..... a cold front will push into northern Ohio Valley and northern mid-Atlantic states on Tuesday.

*** In the East Coast states.... conditions will be mostly unfavorable for disease development Monday and Tuesday. Scattered showers are possible in the northern mid-Atlantic area on Tuesday, ahead of the approaching cold front. Low Risk for the growing areas of PA, MD, VA, and NC on Monday. There will be Moderate Risk on Tuesday for the PA and MD growing areas, while growing areas in VA and Carolinas remain at Low Risk.
*** In the southern Appalachian Mountains.... conditions are mostly favorable for disease development Monday and Tuesday. Strongly Moderate Risk for this region both days.
