Relative humidity measures how much moisture is in the air compared to how much it could hold at a given temperature. It is simply the dew point temperature divided by the air temperature, times 100.

There are multiple ways to describe how wet the air is (yes, pretty much all air is wet). What I mean by that is there are water molecules tucked in between the gases like nitrogen and oxygen that ...

MOLINE, Ill. — When our Storm Track 8 Weather Team talks about muggy conditions, they usually refer to the dew point rather than humidity. The dew point is typically a better measure of the atmosphere ...

Higher dew points can mean misery. Parts of the United States have gotten an early taste of summer weather, as temperatures and humidity are on the rise. Summer can start to feel particularly sticky ...

It’s a hot summer day and you hear someone say, “The relative humidity is 80%!” They’re probably correct, but relative humidity is just not a good way to measure how muggy the air “feels” to our ...

SIOUX FALLS, S.D. (KELO) — Summertime heat is on the way, along with muggy conditions. Meteorologist Adam Rutt explains why we focus on the dew point to talk about humidity. We’ve had a little taste ...

Last week, we talked about why the dew point is a better measure of mugginess instead of relative humidity. When the dew point gets above 70°, that is usually due to tropical air being sent into North ...

It’s that time of year when the lexicon of the meteorologist regularly includes the phrase dew point. This concept is often confused with relative humidity which doesn’t tell us anything about how you ...

Is wet bulb temperature the same as dew point? Mike Moss: In a saturated air parcel (with relative humidity 100%) the wet bulb, dry bulb and dew point temperatures are all the same. In a drier parcel ...
