Upper-level trough is making it cold in Ohio, says the NWS. An upper-level trough, or low atmospheric pressure that makes the air colder than usual, will sit over the Great Lakes and the Ohio ...
Toronto pressure fell to 28.40 inches, breaking its record by 0.17. The 956.0 mb (28.23 inHg) barometric pressure measurement recorded in Mount Clemens, Michigan, was the third-lowest non-tropical atmospheric pressure recorded in the mainland United States [6] and the lowest in the Central United States.

Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

www.weather.gov /nwr /. NOAA Weather Radio (NWR), also known as NOAA Weather Radio All Hazards, is an automated 24-hour network of VHF FM weather radio stations in the United States that broadcast weather information directly from a nearby National Weather Service office. The routine programming cycle includes local or regional weather ...
In most regions, if the atmospheric pressure drops at least 24 millibars within 24 hours, it is considered a bomb cyclone. Bomb cyclones can occur when a cold air mass collides with a warm air ...
An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the Earth's surface varies between 940 and 1040 hPa (mbar).
