Severe Weather Threats Across the Plains; Dangerous Heat and Wildfire Concerns for the West; Watching the Tropics

Severe thunderstorms are expected across the Central Plains accompanied by damaging wind gusts and large hail. In addition, heavy rainfall may lead to instances of flash flooding from the Plains and mid-Atlantic regions. The heavy rainfall threat continues across Florida and across the northern Gulf as we monitor a tropical disturbance tracking westward. Critical fire weather for the Great Basin. Read More >

Fahrenheit (^o F)
Celsius (^o C)

Wind Chill Index Calculation
Enter in the air temperature (T_air) in degrees Fahrenheit and wind speed (mph), then click "Compute WC" to get the wind chill index (WCI). For more information about the WCI, click here.
T_air		mph

Relative Humidity Calculation
Enter in the air temperature (T_air) and dew point temperature (T_dp) in degrees Fahrenheit (^oF) then click on "Compute RH" to get the relative humidity (RH).
T_air		T_dp

Heat Index Calculation
Enter in the air temperature (T_air) in degrees Fahrenheit and relative humidity (RH) in percent (without the % sign), then click on "Get HI" to compute the heat index (HI). For more information about the HI, click here.
