Minimum Temperature
This is the lowest temperature recorded during a specified period of time. The time period can be 6, 12 or 24 hours. The most common reference is to the daily minimum temperature, or "low."

If the forecaster feels that it is warranted, he or she can issued it for amounts less than the minimum criteria. For example, it may be issued for the first snow of the season or when snow has not fallen in long while.
National Weather Service criteria includes the rate of temperature fall and the minimum to which it falls, depending on the region of the country and time of the in year.
Bounded Weak Echo Region (BWER)(Also known as a vault.) Radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by, higher reflectivities aloft.
So, every day, she records the precipitation and the maximum and minimum temperatures using thermometers, an eight-inch rain gauge and a gauge which weighs and charts precipitation. She says she takes readings whenever she passes, even at midnight.
Low Pressure SystemAn area of a relative pressure minimum that has converging winds and rotates in the same direction as the earth. This is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
When do maximum and minimum temperatures occur?
A. A common misconception, is that it must be coldest in the middle of the night, and warmest around midday. On some occasions, mainly due to air mass changes, this may be correct, but not usually.
The most intense storm on record was Typhoon Tip in the northwestern Pacific Ocean in 1979, which reached a minimum pressure of 870 mbar (25.69 inHg) and maximum sustained wind speeds of 165 knots (85 m/s) or 190 miles per hour (310 km/h).
The minimum pressure was 931 mb, the maximum winds were about 26 km from the centre, and the storm moved at about 6 m/s.
The goal of TRMM is to obtain a minimum of 3 years of climatologically significant observations of rainfall in the tropics. Because rainfall is such a variable phenomenon, adequate sampling is a difficult problem.

The index is computed by subtracting a base temperature of 50oF from the average of the maximum and minimum temperatures for the day. Minimum temperatures less than 50oF are set to 50, and maximum temperatures greater than 86oF are set to 86.

Mesopause: the top of the mesosphere, corresponding to the level of minimum temperature in the atmosphere found at 70 to 80 km.
CYCLONE An area of closed pressure circulation with rotating and converging winds, the center of which is a relative pressure minimum. The circulation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Sometimes indicated by the minimum number of significant digits required for an adequate representation of a quantity. Not the same as accuracy but often confused as such.
Mesosphere The region of the atmosphere between about 50 km and 80-85 km, extending from the top of the stratosphere to the upper temperature minimum.
It is a midday minimum designed to reduce the effects of flares.

Issued for winter storms with sustained or frequent winds of 35 mph or higher with considerable falling and/or blowing snow that frequently reduces visibility to 1/4 of a mile or less. These conditions are expected to prevail for a minimum of 3 hours.
Use of technical terms should be kept to a minimum.) But there are some terms for which the meanings are both important and specific.
