This report describes the historical weather record at the Minneapolis-Saint Paul International Airport (Minneapolis, Minnesota, United States) during 1950. This station has records back to December 1947.
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 (67%), built-up areas (18%), forests (9%), and lakes and rivers (5%)
Daylight saving time (DST) was observed at Minneapolis, Minnesota during 1950. There were two time changes during 1950:
1950 was not a leap year, so it has 365 days and no February 29th. The first leap year before 1950 was 1948 and the first after was 1952.

This station reports both the quantity of liquid precipitation and categorical observations of precipitation (e.g., moderate rain, or heavy snow). Both are subject to erroneous reports, but the former is particularly prone to false reports, especially ones indicating an excessive quantity of precipitation. Please bear this in mind when reading the extrema reported in this section.
The day with the largest quantity of precipitation was August 28. That day saw 1.114" of liquid (or liquid equivalent) precipitation, compared to a median value of 0.161". The month with the most precipitation was July, with 3.764", compared to a median value of 3.031".
As determined by quantitative measurements, the longest dry spell was from October 17 to November 1, constituting 16 consecutive days with no measured precipitation. The month with the largest fraction of dry days was August, with 81% of days reporting no measured precipitation at all.
The month with the largest fraction of days with at least some measured precipitation was December, with 58% of days reporting some measured precipitation.
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 1950 with the most precipitation observations was January 3. There were 24 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 290 hourly present weather reports involving some form of precipitation.
As determined by the present weather reports, the longest dry spell was from October 17 to November 1, constituting 16 consecutive days with no observed precipitation. The month with the largest fraction of days without observed precipitation was August, with 77% of days reporting no observed precipitation at all.
The month with the largest fraction of days with at least some observed precipitation was December, with 84% of days reporting some observed precipitation.
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 1950 with the largest number of those reports was May, with a total of 99 reports. The day with the largest number of those reports was September 12, with a total of 20 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 1950 was on November 3; the last was on May 6. The month of 1950 with the largest number of those reports was December, with a total of 286 reports. The day with the largest number of those reports was January 3, with a total of 24 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 1950 was June with an average daily low humidity of 41%, and the most humid month was December with an average daily low humidity of 64%.
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 1950, January had 31 dry days, no comfortable days, and no humid days; April had 29 dry days, 1 comfortable day, and no humid days; July had no dry days, 27 comfortable days, and 4 humid days; and October had 20 dry days, 11 comfortable days, and no humid days.
The highest sustained wind speed was 51 mph, occurring on May 6; the highest daily mean wind speed was 32 mph (May 6); and the highest wind gust speed was 34 mph (June 4).
The windiest month was June, with an average wind speed of 14 mph. The least windy month was September, with an average wind speed of 9 mph.
Visibility is the maximum distance at which a given reference object or light can be clearly discerned. In the United States, visibilities that are greater than or equal to 10 miles are typically reported as 10 miles.
The day of 1950 with the lowest average visibility was March 21, with an average visibility of 1.7 mi. The month with the lowest average visibility was December, with an average visibility of 9.5 mi. With an average visibility of 14.0 mi, the month of June had the highest average visibility.
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 1950 with the lowest average cloud ceiling was May 22, with an average cloud ceiling of 0'. The month with the lowest average cloud ceiling was December, with an average cloud ceiling of 5577'. The month of July has the highest average cloud ceiling, with an average cloud ceiling of 12467'.
