Wednesday Update -Continued Blocked Pattern

Update Wed 05/03 @ 9:37 AM —The blocked pattern will slowly transform into another blocked pattern over the weekend. By the weekend, our part of the country will be under more of an upper ridge than the current upper low. Until that time we’ll continue with unsettled weather: clouds, some sun, scattered showers, and cool temperatures.

Today, Wednesday, we’ll likely have the most widespread shower activity, but both Thursday and Friday may have a few late afternoon showers in some areas.

Here’s what things look like by Sunday
