The reduced staffing could make it more difficult to gather and process the data coming in from across the country — on temperature, wind speed, and dew points, among other things.

Firstly, there’s the cooling and condensation process which cools humid air to its dew point, causing water vapour to condense into liquid water.

According to AccuWeather’s chief meteorologist Jonathan Porter, their index factors in weather conditions that NWS’s wind chill does not, such as dew point, cloud cover, and precipitation.

“With these very hot temps, generally, we’re going to see lower dew points, which can lead to fire concerns,” Adams said.
