In between these features, most areas will have dry conditions and fair to partly cloudy skies Wednesday and Thursday. The approaching front will generate some scattered showers and thunderstorms in the Ohio Valley on Thursday. Highs mostly in the 80's with some 70's north and 90's to the south.
*** There is a threat to the Canadian growing areas on Thursday. *** Trajectories from the Ohio Valley sources will be moving northeast on Thursday. Conditions will be mixed for survivable transport of spores and scattered showers are expected along the forecast pathways. Trajectory centerlines will pass south of Lake Erie and Lake Ontario, but airborne spores away from the main body may be deposited in southern Ontario. Deposition is also possible in the Ohio Valley region. Moderate Risk for the growing areas of the Ohio Valley and southern Ontario on Thursday. In the Ohio Valley on Wednesday..... and both days in other regions .... conditions are unfavorable for survivable transport or deposition, with Low Risk to commercial tobacco crops.
