Weather in Context Tool Usage Manual
Welcome to the Weather in Context project prototype page. Quite simply, the goal of this project is to develop a web-based tool that displays forecast information and its climatological context in a manner that will quickly alert a forecaster to when a record or near-record breaking event is possible. The tool focuses on maximum temperatures, minimum temperatures, precipitation, and snowfall. The default table displays the number of ThreadEx stations where the National Digital Forecast Database (NDFD) temperature forecast breaks or comes within 4 degrees of breaking a given temperature record and where the NDFD precipitation forecast is at least 50% of the precipitation record. Clicking on a cell in this table produces a map that displays the locations of these stations as well as the potentially record breaking NDFD forecast for these stations. There is also now a version of this table for the National Blend of Models (NBM) forecast. To view forecast data at a particular ThreadEx station, select the desired station from the searchable menu and click 'view table'. The table generated will display the NDFD or NBM forecast of maximum temperatures, minimum temperatures, and precipitation for the next week, color coded by how close the forecast comes to breaking the record. Clicking on a cell in this table will display a violin plot which shows the GEFS forecast distribution and how it relates to the record. The color coding of how many stations are forecasted to break or nearly break their temperature or precipitation records is as follows:
The color coding of how close the NDFD or NBM temperature or precipitation forecast at a particular station comes to the record is as follows:

Mouseover the numbers above to show a list below. Keep in mind that this display shows the number of (usually major) cities that are forecast to be near (by <1°F), tie, or break the record. There are ~390 stations in the CONUS database as of April 2020. Data updated through 12/31/2019. |
