KEY MESSAGES

- Scattered thunderstorms through early evening Wednesday. Risk of small hail and possible funnel clouds.

- Growing signal for strong to severe storms this weekend into early next week.

..Severe potential this weekend and next week

With upper flow transitioning to southwesterly, the pattern looks to be warmer and more active with several weak shortwaves coming through. The timing of these shortwaves is still not resolvable at this point, but several rounds of thunderstorms look possible. The position of the ridge axis would make it seem that the best chances for Saturday afternoon and tonight for severe will be over the western Dakotas, but can't rule out some convection impacting the Devils Lake Basin that night. CWASP 50th percentile probabilities of 60 or more transition a bit further east for Sunday into next week. However, much will depend on timing of weak lead shortwaves and how much destabilization we get. Pattern looks active but details uncertain at this point.
