Gotcha. It looks like about a 5-6 day period of troughing to me, starting yesterday.
But yes, the weekend will have the greatest departures. Still, a lot of places put up solid negatives the past couple days, and will also today and at least Monday.
Looks like airmass/pulse type storms in the areas farther south, which may mean that coverage may be even less than depicted (but some very isolated spots may rack up more than shown). By and large, flash drought concern could be on the rise in much of the OV and at least up to the southern Lakes.
Sorry for going about it unkindly, just trying to say Saturday and Sunday are so anomalous that a multi day average with either of those days is massively skewed. It does look like troughing will dominate until early july
