A strong storm system will impact the region Thursday. The graphic below shows one model's forecast of deep low pressure near Chicago early Thursday afternoon. A storm system with pressure this deep will result in very windy conditions across the Ohio Valley increasing through the day Thursday, peaking in the afternoon just behind a strong cold front. Expect southerly winds between 15 and 25 mph, gusting to 35 mph during the morning hours. Then, winds will increase to 20-30 mph, gusting between 40 and 50 mph by the afternoon. A Wind Advisory will go into effect at 4 AM EST / 3 AM CST early Thursday morning.
Those with loose outdoor objects including trash cans, Christmas decorations, etc. should take precautions to secure them before Thursday.
Widespread rain is expected Thursday morning through early Thursday afternoon ahead of the strong cold front. Some gusty showers or thunderstorms will likely move over and then east of Interstate 65 during the early afternoon hours. The image below reflects our current forecast of precipitation amounts with this system.
As colder air moves into the region Thursday evening, precipitation will likely end as light snow showers over southern Indiana and north central Kentucky. Little to no snow accumulation is expected at this time. However, strong winds may produce reduced visibilities in snow showers and some slick spots may form on roadways.
