The models show a better chance of widespread wetting rains later today through the weekend. At the moment, I do not see this pattern letting up very much into next week. Keep the umbrellas handy. We may even see consistently cooler temps over the next several days.
I have not shared many precipitation maps this summer. Because the pattern appears to intensify in the short term, I’ve decided to share the precipitation forecast total maps. I would not zero in on specific areas but on the event as a whole.
Looking at other parameters, models show PWAT (precipitable water values) moving up to 150%-180% of normal and remaining there over the weekend. This equates to actual column values between 1.1 and 1.7 inches of rain. All of this is a fancy way of saying that there will be heavy rain threats, with flash flooding potential in areas that favor that.
Here are the maps. Based on the PWAT column totals, much higher weekend totals will not surprise me a bit.

If you want to track totals, track them over the weekend before you send them, and we will see how well the models did by Monday morning.
