About Selected Cities
Since the early 1970's, the NWS’s National Centers for Environmental
Prediction (NCEP) have issued two widely-distributed text products,
the Selected Cities Summary (SCS) and the Travelers Forecast (TAV).
The SCS provides basic observations (Temperatures and Precipitation)
for the previous day and 2-day forecasts of temperature and Character
of Day (CoD) for 162 cities in the United States, Puerto Rico and
the U.S. Virgin Islands, while the TAV provides 2-day forecasts
for 30 US cities and Puerto Rico. Each of these products is created
by gathering the Coded Cities Forecasts (CCF) issued by NWS Weather
Forecast Offices (WFOs) and adding previously observed weather
NWS instruction 10-504, “National Public Weather Forecast
Products Specification,” describes the generation of the
“NCEP’s Hydrometeorological Prediction Center (HPC)
issues the Selected Cities Forecast to provide observed maximum
and minimum temperatures, observed precipitation, and forecast
weather and temperatures for 162 cities in the United States,
Puerto Rico and the U.S. Virgin Islands. This product is heavily
used by the print media and supports the public weather program.”
The SCS is a highly visible product that is issued twice daily around 0100 and 1300 Coordinated Universal Time (UTC). Cities covered in the SCS product are listed in alphabetical
order and the product is divided into four sections to enhance
readability. The range of cities covered in each section are:
- Part 1 -- Abilene, TX through Columbus, OH
- Part 2 -- Concord, NH through Lexington, KY
- Part 3 -- Lincoln, NE through St. Thomas, V.I.
- Part 4 -- Salem, OR through Yuma, AZ
The last section of Part 4 also includes the observed High and
Low temperatures from the continental United States (CONUS).
