Climate Summary Tables

Climate Summary Tables (MRCC)

Access comprehensive climate normals, extremes, and threshold statistics
Obtain tabular data from the U.S. Cooperative Observer Network consisting of the National Centers for Environmental Information climate normals, temperature and precipitation extremes and threshold climatologies.
  • View daily, monthly, and seasonal temperature and precipitation normals and records
  • Access tables of climate extremes, including record highs, lows, and precipitation events
  • Analyze frequency of threshold events, such as days above or below specific temperature or precipitation values
Climate Perspectives

Climate Perspectives (SRCC)

Analyze recent climate conditions in historical context
Climate Perspectives offers real-time monitoring and ranking of climate data against historical records (1991–2020) for Midwest stations. Users can explore local data, regional summaries, threshold exceedances, and streaks, placing current weather events in a broader climate context for informed decision-making.
  • Rank daily, monthly, and seasonal temperature and precipitation against historical records
  • Visualize streaks and threshold events, such as consecutive days above or below temperature or precipitation thresholds
  • Customize searches by date, period, variable, and threshold for advanced analysis
Daily Climate Extremes

Daily Climate Extremes (MRCC)

Explore temperature, precipitation, and snowfall extremes
This map-based product provides daily climatological extremes for U.S. locations, including maximum and minimum temperature, precipitation, and snowfall.
  • Identify the average warmest and coldest days of the year for any station
  • View record high and low temperatures, precipitation, and snowfall values
  • Determine when a station typically receives the most or least precipitation
  • Filter and customize map displays by variable, record vs. normal, and value or date
Snowfall Climatology Toolbox

Snowfall Climatology Toolbox (MRCC)

Explore historic snowfall data across the Midwest
This tool offers access to high-quality historical snowfall data across the US.
  • View average annual and monthly snowfall totals by location
  • Identify the average first and last dates of measurable snowfall
  • Analyze the number of days per year with at least 1 inch of snowfall
  • Explore records for greatest single-day and seasonal snowfall

Heat Index Maps

Heat Index Maps (MRCC)

Visualize annual heat index trends and thresholds
The MRCC Heat Index Maps tool displays climatological maps of heat index thresholds for the US.
  • Map the number of days and hours above selected heat index thresholds (e.g., 90°F, 95°F, 100°F)
  • View annual counts of days with extended periods (minimum three hours) of dangerous heat
Heat Index Probability Curves

Heat Index Probability Curves (MRCC)

Analyze the probability of exceeding key heat index thresholds
The MRCC Heat Index Probability Curves tool provides interactive charts showing the likelihood of reaching or exceeding specific heat index values on any given day throughout the warm season. Users can explore how often dangerous heat levels occur at selected stations, supporting risk assessment for health, agriculture, and emergency planning.
  • Visualize the daily probability of exceeding various heat index thresholds (e.g., 90°F, 95°F, 100°F)
  • Compare heat risk profiles across different locations and time periods
  • Identify peak periods for extreme heat to inform safety and management decisions
