ⓘ About this reading (NWS)
Current conditions: the NWS gridpoint forecast for this hour (no recent station observation was available).
Forecast highs, lows and hourly values: the NWS Gridpoint Forecast for the grid cell that contains this location, issued by the NWS SJU Area Forecast Office.
Open-Meteo model estimates supplement fields not reported by NWS.
A gridpoint forecast describes the average over its grid cell, while a station measures one spot (often an airport), so the two can differ by a few degrees, especially during strong winter temperature inversions, which are common around Fairbanks.
Mostly clear, winds are light.
