Hi All,
We noticed something and wondered if anyone else on here had encountered 
this and/or has an idea what's happening.
Beginning on Saturday, September 7, some time after 0500 UTC, our requests 
began receiving NDFD XML output from the NCEP SOAP Service which has the 
forecast for previous day(s). For example, our query at 1240 UTC on Sep 7 
yielded XML like this:
      <creation-date 
refresh-frequency="PT30M">2024-09-07T12:15:07Z</creation-date>
      [...]
    <time-layout time-coordinate="local" summarization="12hourly">
      <layout-key>k-p24h-n7-1</layout-key>
      <start-valid-time 
period-name="Friday">2024-09-06T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-06T18:00:00-05:00</end-valid-time>
      <start-valid-time 
period-name="Saturday">2024-09-07T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-07T18:00:00-05:00</end-valid-time>
      <start-valid-time 
period-name="Sunday">2024-09-08T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-08T18:00:00-05:00</end-valid-time>
Note that it still included Friday.
Queries to this service from earlier today (Friday) yielded similar 
strange results:
      <creation-date 
refresh-frequency="PT30M">2024-09-13T19:05:27Z</creation-date>
      [...]
    <time-layout time-coordinate="local" summarization="12hourly">
      <layout-key>k-p24h-n7-1</layout-key>
      <start-valid-time 
period-name="Tomorrow">2024-09-12T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-12T18:00:00-05:00</end-valid-time>
      <start-valid-time 
period-name="Friday">2024-09-13T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-13T18:00:00-05:00</end-valid-time>
      <start-valid-time 
period-name="Saturday">2024-09-14T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-14T18:00:00-05:00</end-valid-time>
      <start-valid-time 
period-name="Sunday">2024-09-15T06:00:00-05:00</start-valid-time>
      <end-valid-time>2024-09-15T18:00:00-05:00</end-valid-time>
We haven't seen any recent NWS change notices which appeared to apply to 
this service, nor any admin messages even remotely related, so we're at a 
loss.
