The stormy pattern Oklahoma has been in this week will continue through Friday. Our region is "stuck" in a northwest flow pattern, which occurs when a low pressure system stays to our northeast, with a high pressure ridge to our southwest. Air above the ground then moves from the northwest to the southeast over Oklahoma. This steers thunderstorms through the state repeatedly, usually forming in the evening and continuing overnight into the early morning hours. Scattered showers and thunderstorms can also develop in the afternoons across the state.
Tuesday morning's event was a perfect example of what can happen in northwest flow. Storms that form tend to have very heavy rainfall, frequent lightning, and gusty winds with some hail.
Tuesday afternoon, scattered showers and thunderstorms were moving southeast across the western half of the state. More thunderstorms are also expected to form and move southeast through the state overnight into Wednesday morning. Some of these storms could be severe with large hail, damaging wind, and very heavy rain with frequent lightning. Southwest Oklahoma has the highest probability of getting these storms.
It appears that the pattern will finally change by the weekend, bringing dry and hot weather.
