This report describes the historical weather record at the Flying Cloud Airport (Minneapolis, Minnesota, United States) during 1983. This station has records back to December 1983.
Minneapolis, Minnesota has a humid continental climate with hot summers and no dry season. The area within 25 mi of this station is covered by croplands (71%), built-up areas (16%), forests (8%), and lakes and rivers (4%)
Daylight saving time (DST) was observed at Minneapolis, Minnesota during 1983. There were two time changes during 1983:
1983 was not a leap year, so it has 365 days and no February 29th. The first leap year before 1983 was 1980 and the first after was 1984.
The summer and winter solstices and the spring and fall equinoxes mark the passing of the seasons. They fall on nearly the same day each year, with differences of a day or two depending on the year. In 1983 they occurred on:
|Spring Equinox||Monday, 21 March 1983.|
|Summer Solstice||Tuesday, 21 June 1983.|
|Fall Equinox||Friday, 23 September 1983.|

This station did not reliably report air temperature during1983.
The clearest month of 1983 was December, with 16% of days being more clear than cloudy.
The cloudiest month of 1983 was November, with 73% of days being more cloudy than clear. The longest spell of cloudy weather was from November 17 to November 24, constituting 8 consecutive days that were cloudier than they were clear.
This station provides hourly reports of significant weather events at and around the station, but does not report the quantity of precipitation at the station itself. This is common for weather stations located outside of the United States, and for a small subset of stations in the United States that are located at lesser used and smaller airports.
This station reports when significant weather events (including precipitation) are visually observed at or near the station. Such events do not always correspond to measured quantities of liquid equivalent precipitation, such as when the event is near by not at the station, or in the case of solid precipitation that does not melt in the collection basin.
The day in 1983 with the most precipitation observations was December 13. There were 15 hourly weather reports that day (out of a maximum of 24) in which some form of precipitation was observated at or near the station. The month with the most precipitation observations was December, with 86 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from December 1 to December 8, constituting 8 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was December, with 68% of days reporting no observed precipitation at all.
In this section we consider only those weather reports that indicate liquid precipitation. For the purposes of this analysis, we include thunderstorms even though some thunderstorms are not accompanied by liquid precipitation.
The month of 1983 with the largest number of those reports was November, with a total of 29 reports. The day with the largest number of those reports was November 19, with a total of 10 reports.
This station reports when snow is observed falling but does not report the quantity of snow that has fallen or the depth of snow on the ground.
In this section we consider hourly weather reports that contain an observation of falling snow. These reports do not necessarily correspond to accumulation.
The first reported snow fall in 1983 was on November 9; the last was on December 27. The month of 1983 with the largest number of those reports was December, with a total of 86 reports. The day with the largest number of those reports was December 13, with a total of 15 reports.
Humidity is an important factor in determining how weather conditions feel to a person experiencing them. Hot and humid days feel even hotter than hot and dry days because the high level of water content in humid air discourages the evaporation of sweat from a person's skin.
When reading the graph below, keep in mind that the hottest part of the day tends to be the least humid, so the daily low (brown) traces are more relevant for understanding daytime comfort than the daily high (blue) traces, which typically occur during the night. Applying that observation, the least humid month of 1983 was November with an average daily low humidity of 100%, and the most humid month was November with an average daily low humidity of 100%.
But it is important to keep in mind that humidity does not tell the whole picture and the dew point is often a better measure of how comfortable a person will find a given set of weather conditions. Please see the next section for continued discussion of this point.
Dew point is the temperature below which water vapor will condense into liquid water. It is therefore also related to the rate of evaporation of liquid water. Since the evaporation of sweat is an important cooling mechanism for the human body, the dew point is an important measurement for understanding how dry, comfortable, or humid a given set of weather conditions will feel.
Generally speaking, dew points below 50°F will feel a bit dry to some people, but comfortable to people accustomed to dry conditions; dew points from 50°F to 68°F are fairly comfortable to most people, and dew points above 68°F are increasingly uncomfortable, becoming oppressive around 77°F.
To take some examples, and basing our categorization on the daily high dew point in 1983, January had no dry days, no comfortable days, and no humid days; April had no dry days, no comfortable days, and no humid days; July had no dry days, no comfortable days, and no humid days; and October had no dry days, no comfortable days, and no humid days.
The highest sustained wind speed was 52 mph, occurring on December 4; the highest daily mean wind speed was 21 mph (November 27); and the highest wind gust speed was 40 mph (November 20).
The windiest month was November, with an average wind speed of 13 mph. The least windy month was December, with an average wind speed of 9 mph.
This station did not reliably report the visibility during 1983.
The cloud ceiling is the altitude of the lowest layer of clouds that are at categorized as broken (mostly cloudy) or overcast (cloudy). If no such cloud layer exists then the ceiling is unlimited and no value is reported.
The day of 1983 with the lowest average cloud ceiling was December 2, with an average cloud ceiling of 82'. The month with the lowest average cloud ceiling was November, with an average cloud ceiling of 4782'. The month of December has the highest average cloud ceiling, with an average cloud ceiling of 6802'.
