Continued warmer than normal this week, but enough moisture and instability will remain for a daily chance for mainly afternoon and evening thunderstorms through the coming weekend. The storms will generally be airmass thunderstorms with little or no organization and slow movement (possibly drifting northeast or east by 5 mph). By Sunday, the Four Corners ridge will flatten out and the winds aloft will become more westerly and then northwesterly early next week. This will likely result in a slight drying and cooling trend over the weekend and into early next week.

The past 5 days we have seen a low-moderate grade monsoon pattern with rainfall totals from less than 0.25” to near 1.0” around the Quad City area. However, precipitation totals for the monsoon thus fare are still anywhere from 2” - 8” below normal. It has really been a dry and hot summer over all!
