DPs are still holding firm in the mid to upper 60s. That works.

Per usual, the HRRR is tracking too low on DPs and the NAM is too high.

0.04” is better than nothing, but not by much

DCA has joined the other airports at hitting at least 96. It'll be interesting to see if any of those cells can make it east. The leading showers are dying after they get to about IAD.

Add one to each of those numbers for the highs thusfar. 94.6 at home.

Low 90s over mid 60s in most places right now. Warm.

It isn’t going to happen, but the Euro and HRRR have DC at 100 on Tuesday.

You nailed it. Crossing into the mid-60s DPs at this time of year is very noticeable.

The 00z Euro kept things south and the 06z GFS depends a lot on the Wed/Thus wave with light precip beyond that. It isn't what we want, but it also isn't set in stone.

Good hit along 95. Every bit helps.

This is a good example of the polarimetric radar being important. If you look at the reflectivity over my house you’d think that it was pouring. The high differential reflectivity and low differential phase indicates that there are large, but relatively few big drops. So, despite a radar that looks like below, I’ve had 0.07” so far in this batch.

Pretty nice line. Hope it holds for the rest of us.

Almost certain that it is. But implementing it is a different beast. Various academic institutions have the run the WRF real-time, but even that is difficult to keep up without dedicated staff.

The radar QPE algorithm is having a terrible time with this event. I’m sitting at 0.23” and DCA is 0.21” and the radar estimate is ~0.7”.
