## Daily outlook
Air temperature and rain use a coastal land-grid forecast; wind and gust use an offshore sea-grid forecast. Rain is the highest hourly probability, not a daily probability or rainfall amount. Amounts are modelled precipitation (rain + showers + snow water equivalent), not amounts conditional on rain occurring. All daily ranges and totals cover the full local calendar day; hourly amounts cover the preceding hour.
