  1. The model scorecard is abysmal. If 100 meant they got precip types, amounts, start and end time, and temperatures correct and 0 meant all wrong then they are squarely at a 35 over the last 2-3 weeks. 

    Luckily , every other scientific entity that we rely on does not operate at this accuracy level 

  2. M*tt

    i have not read anything for hours so will catch up but I think you say you never like it when precip shoots up into PA from our west and then curls eastward all the way to far eastern PA and well east of DC at that point!

    did I get it right?

    do you have that concern tonight if I did ?

    I agree that there's opportunity there. In fairness though, IBM does have a model (which we laugh at) and they are a leading supercomputer manufacturer. I think part of the problem may be data acquisition for model input. NWS has a large network to gather data that would be really expensive to replicate. I'm not sure that data is all readily accessible. The old data adage "garbage in, garbage out" is very accurate. So even if IBM or Musk could build an epic supercomputer and program top-notch physics into it, the model would still be crap without good data. 

    That’s why outcome analogs should be the method and not theoretical physics.

    Very good data since 1960. 60 years.  Let’s say there are 3 Miller As per season, 180 sample size.

    Break those 180 down to

    1. The low passes within 30 miles of Atlanta.

    2. The low is more than 30 miles north of Atlanta 

    3. The low is more than 30 miles south of Atlanta 

    then overlay that with

    1.The high is 30.30 or higher 12 hours before onset

    2.The high is lower than 30.30

    You will get a decent sample set of 10-20 matching outcomes in each category.  No wailing about sample size, the outcomes are what they are

    When you take #1 on the storm and #1 on the high and 20 instances arise and 15 times DC got 3” or more then there is your model replacement 

    When you take #2 and #2 and 22 instances match and 16 times DC got rain then there is your new and improved, outcome based, non model forecasting.

    The will is not there mostly  due to entrenched commitment to status quo and embedded money issues.

    i promised you all I had a solution and not just bitching. Let the naysay begin.

    You can delete my post or ridicule me. But we have seen this before. This set up is ready to let us down. I hope not, but the models do not favor us.

    But the situation does favor us.  High in the right place, western low some problem but not strong nor too far north, then coastal and by now it’s a drawn out event thru Friday. Highs 25-30
