Each model's day runs midnight to midnight local time; models that reach fewer days are left blank. Rain: daily total. Wind: the day's highest average wind and, in small type, the strongest gust. Highlighted: values that stand out from the rest. The chance of rain comes from many runs of the same model with slightly different starting data.

Humidity86%
Dew point77 °F

Humidity is 86% now and the dew point is 77 °F. With a dew point this high, it feels muggy.

The dew point is the temperature at which the air becomes saturated: the higher it is, the heavier the air feels.

Visibility and fog

Now15 migood
Clouds85%

Visibility is good now (15 mi). No fog expected today.

The model gives visibility up to about 15 mi: beyond that, the horizon is clear.
