Forecast from August 22nd
A potent low pressure system located over the Lake Michigan is setting the stage for severe thunderstorms and flash flooding from northeastern Colorado, Nebraska, Iowa, northern Illinois, and Michigan. High pressure is controlling the west coast, which is allowing for mostly clear and dry conditions. High pressure in the Southeast is producing dry conditions for the southern states, with the exception of southern Florida and southern Texas where a few showers or thunderstorms are possible.
Risk Area: Winds from the southwest in northern Texas and Oklahoma are permitting spore transport as far north and east as Michigan. There are also considerable cloudy and rainy conditions in the Great Plains and Great Lakes regions which is allowing for spore deposition. Dry conditions over the majority of the South are decreasing the ability for spore survival and deposition from eastern Texas to Florida. Southern Texas will be an exception as strong winds and showers from Hurricane Dean are creating ripe conditions for spore transport, deposition, and survivability.

Forecast: August 23-24
The low pressure system in the Great Lakes will continue to move northeastward with its trailing cold front sliding east and will bring the potential of heavy rain and thunderstorms to Kansas, Nebraska, Missouri, Illinois, Iowa, Wisconsin, and Michigan. The South will continue to see mostly clear conditions produced by high pressure in North and South Carolina. The West will also continue to remain mostly clear and dry.
Risk Area: The risk for spore transport will be very high in northern Mexico and southern Texas due to the influence of Hurricane Dean. Spore transport is possible into areas of Kansas, Missouri, Iowa, and Nebraska, and with a forecast for rain, deposition is also possible. High pressure will continue to affect the Southeast, which will decrease the opportunity for spore survival and deposition. Winds will be mainly from the east in Florida which will contain the spores from spreading further north than the infected areas.

Forecast: August 25-27
The trailing cold front from a low pressure system moving through southern Canada will produce showers from the Great Lakes to the Mid-Atlantic and the Northeast. A disturbance will produce showers for Florida, Georgia, South Carolina, and Alabama. The west coast will continue to experience mostly clear and dry conditions from high pressure in the eastern Pacific Ocean.
Risk Area: Winds from the southwest in Texas and Oklahoma will create the potential for spore spread into northern Oklahoma, Missouri, and Kansas. Rain and cloudy skies will be limited in those areas which will limit any spore deposition and survival. Some spore transport may be possible into northern Kentucky, southern Illinois, and Indiana because of winds from the west, but disease spread to these areas is unlikely. Spore survivability and deposition will be high in the Florida, Georgia, and Alabama due to a disturbance producing rain and cloudy skies.
