Strong Atmospheric River Bringing Heavy Rain to the Pacific Northwest; Areas of Snow in the North-Central and Eastern U.S.

A strong atmospheric river will bring prolonged heavy rainfall along with gusty winds to the Pacific Northwest through much of this week. The heavy rainfall may lead to widespread urban and river flooding. Accumulating snow is expected over parts of the central Appalachians and Mid-Atlantic today as well as the Upper Midwest and the Upper Great Lakes this evening into Tuesday. Read More >

Temperature Conversion

Enter a number then click on the appropriate number to see the result.
Fahrenheit (^oF)

Wind Chill/Temperature Index Calculation in degrees Fahrenheit Enter in the air temperature ( T_air ) in degrees Fahrenheit and wind speed in mile per hour ( mph ), then click on the Calculate WC to compute the windchill ( WC ).
T_air^o F		mph

Wind Chill/Temperature Index Calculation in degrees Celsius Enter in the air temperature ( T_air ) in degrees Celsius and wind speed in miles per hour, then click on the Calculate WC to compute the windchill ( WC ).
T_air ^o C		mph

Relative Humidity Calculation using degrees Fahrenheit Enter in the air temperature ( T_air ) and dew point temperature ( T_dp) in degrees Fahrenheit ( ^oF ) then click on the Calculate RH to compute the relative humidity ( RH ).
T_air ( ^o F )		T_dp ( ^o F )			RH T_air T_dp

Relative Humidity Calculation using degrees Celsius Enter in the air temperature ( T_air ) and dew point temperature ( T_dp) in degrees Celsius ( ^oF ) then click on the Calculate RH to compute the relative humidity ( RH ).
T_air ( ^o C )		T_dp ( ^o C )			RH T_air T_dp

Heat Index Calculation

Valid entries are, air temperatures greater than 80 °F ( 27 °C ), dew point temperatures greater than 65 °F ( 12 °C ), and relative humidities higher than 40 percent.

in Celsius Enter in the air temperature ( T_air ) and the dew point temperature ( T_dp ) in degrees Celsius, then click on the Calculate HI to compute the heat index ( HI).
T_air in °C		T_dp in °C				RH =

in Fahrenheit Enter in the air temperature ( T_air ) the dew point temperature ( T_dp ) in degrees Fahrenheit, then click on the Calculate HI to compute the heat index ( HI).
T_air in °F		T_dp in °F				RH =

in Celsius Enter in the air temperature ( T_air ) in degrees Celsius and relative humidity ( RH ) in percent ( without the % sign ), then click on the Calculate HI to compute the heat index ( HI ).
T_air in °C		RH				T_dp =

in Fahrenheit Enter in the air temperature ( T_air ) in degrees Fahrenheit and relative humidity ( RH ) in percent ( without the % sign ), then click on the Calculate HI to compute the heat index ( HI ).
T_air in °F		RH				T_dp =
