I have noticed, the last week or two, that the global models (all of them) are doing terribly at predicting the pop up convection type rains we have seen recently. Broad brushing qpf for everyone. Unfortunately in the last few days the non global Nam is doing the same thing. Make using of most traditional models, for qpf forecast, fairly useless. Re: here is what the 12Z Nam says we see this afternoon. Almost every mile of PA gets rain. Let me know when it happens. I understand the lower resolution models will broad brush a bit too much but this is beyond broad brushing and just outright wrong (at least the last week or so).
