The National Weather Service office in Chicago experienced a partial outage on the official website Sunday April 15, 2018 morning. The National Weather Service Office Chicago responded promptly to a report of the problem Sunday morning, and stated they were looking into the problem. The Click Map for Forecast is broken, as any click on a point in Cook County does recognize O’Hare current observations for area-specific forecasts, and refers to the entire Cook County area. Any search for “O’Hare Chicago, IL” did not find the O’Hare forecast or current observations for the major airport (KORD). Instead, results were displayed for Chicago Midway Airport (KMDW).
UPDATE: Issue was fixed by 8:10 a.m.
For example, in normal operations, clicking on an area inside an area in Cook County in the map on the right side of the NWS web page should produce a forecast for the few square miles around that click on the map. If users clicked on Hoffman Estates on Sunday morning April 15, 2018, they did not get a forecast specific to Hoffman Estates. Instead users were referred to a generalized area for the entire area of Cook County, and received results that locked on to Chicago Midway Airport (KMDW) current observations and forecast. The same failed conditions occurred for any other clicks on a suburb, such as Arlington Heights, Skokie, Tinley Park, etc.
A click at a suburb position inside DuPage, Grundy, Kane, Lake (Illinois), Lake (Indiana), McHenry, porter (Indiana) and Will counties presented the same website failure.
Locally, the problem did not effect NWS information for Kenosha County, which is part of the NWS Milwaukee Local Forecast Office.
Other metropolitan areas in the United States associated with their respective NWS local forecast offices did not seem to be affected by the website failure observed for the Chicago local office.
No Failures Observed at the following local forecast offices …

New York, NY
Miami-South Florida, FL
