Why do the grids lead
to such bizarre worded forecasts?
Models are getting really good – but programs and algorithms
that convert model output to text are not very good. Forecast wording issues
reflect problems with the post-processing. Baseline worded forecasts from the
various algorithms (in which Regional and higher levels seem to have no
interest) are basically considered “good enough.” There is minimal investment
in meteorologically sound, post-processing systems. Absurd public text
forecasts occur because there no longer is importance given (at different
Headquarters levels) to issuing worded forecasts that make sense. Why not
average model output over three-hours, or use “wintry mix” instead of things
like “rain, then snow, then rain mixed with snow, then freezing rain”? There need
to be more people working to make these kind of improvements.
Conflicting responsibilities
A related issue is that forecaster attention is increasingly
being shifted/mandated to “IDSS” (Impact-based Decision Support Services) and
various social media and away from direct involvement in the daily forecast
process.
Forecasters are stuck in a trap re providing best product
for public but they are also required to produce “pleasing” maps.
Today it's more about collaboration, chat rooms, webinars,
conference calls, Facebook, etc., and direct interaction with users in real
time during events. The overall trend in forecast services isn't surprising.
Many could see the proverbial writing on the wall many years (even decades)
ago.
Human vs Automated
Forecasts
Fewer people in our urbanized truly need to know about
weather details –the small fraction of people who need detail probably know
better sources than NWS text forecasts.
Models have improved steadily while forecasters have not
(meteorological cancer as per Snellman and many others).
Most of time human forecasters can’t do better than blended
models on days 4 to 7. Waste of time for forecasters to try to improve base
variables in the forecast except in frontal/convective situations and western
US complex terrain effects.
No problems with blended model forecasts producing the
forecast beyond day 3.
Fully automated forecasts are the future in public sector
forecasts. In public sector forecasting emphasis ($$) has mostly been in NWP
with little investment in humans.
