Surface: what stations observe and WPC analyses
On the map
- Observed temperature, °F, above-left of the station
- Observed dew point, °F, below-left
- Observed temperature and dew point are left off the map on a screen this narrow: the table below lists every station’s.
- Observed wind: the staff points to where it blows from; a full barb is 10 kt, a half 5, a pennant 50; a ring is calm
- Analysis cold front
- Analysis warm front
- Analysis stationary front
- Analysis occluded front
- Analysis dry line
- Analysis trough
- Analysis high and low pressure centres, with their pressure in millibars
WPC’s bulletin does not say which side of a front its symbols go, so this map draws no triangles or half-circles; each front is named on the map and in the list.
Observed 2,239 stations, each at its own time, most between and . Airport and other automated stations’ reports (METARs), as AviationWeather.gov decodes them. Left out: 468 reports flagged by the station for maintenance and no reports that cannot be right; no other quality control is applied here.
Analysis WPC’s surface analysis valid , issued . A forecaster’s analysis of the fronts and pressure centres at that hour, every three hours.
