Well, drat. I got a bit engrossed in work this morning and lost a good chunk of some really cool migration and weather dynamics and was only able to salvage the last part.
What happened is that early in the evening we had widespread rain that slowly moved off to the east. And you could see the migration advance right along the storm line. Anyway here is the look after the storm had passed and it was widespread and heavy. Pretty much what we expect after a week of challenging weather.
