Planning a flight from western Oklahoma to eastern Tennessee, what flight conditions do you expect according to the 12-hour prognostic?

The rationale behind the expectation of IFR conditions initially, with improvement eastbound, lies in understanding the typical weather patterns and phenomena that can affect flights in that region. When planning a flight from western Oklahoma to eastern Tennessee, it's important to consider factors such as seasonal weather systems, atmospheric conditions, and the forecasts provided in a 12-hour prognostic.

In the context of this flight route, western Oklahoma may be experiencing low visibility and clouds, often resulting in Instrument Flight Rules (IFR) conditions. These conditions can arise from various factors, including frontal systems or moisture-laden air typical during certain times of the year. However, as one progresses eastward towards eastern Tennessee, the weather may improve, leading to more favorable Visual Flight Rules (VFR) conditions.

Forecast models indicate that while departure might start under IFR due to lower ceiling and visibility, the weather patterns shifting toward eastern Tennessee are likely to bring about improvements in visibility and overall flight conditions. This can be due to factors such as the dissipation of cloud cover or the movement of high-pressure systems that often lead to clearing skies.

Thus, acknowledging the dynamic nature of weather across this significant distance is essential for flight planning, as it leads to the anticipation of IFR conditions initially, followed by a likely
