![]() Stay warm and safe on these chilly days! Winter has only just begun. You can access this information via the menu in the top left (Menu à Weather à Freeze Monitor) or at /weather/freezeįigure 3. ![]() It allows you to track the hours below 32 or 24 oF thresholds useful for permafrost development or winter wheat/cover crop damages. The freeze monitor data is available on our webpage as well. Winter wheat and cover crop producers still have an interest in the cold temperatures. How many hours has the temperature been below freezing? You can also select a specific station either on the map or in the data table, and it will display the specific information for that location.įigure 2. Click it again, and it will reverse the order. By clicking the column headings, that particular column will sort from lowest to highest values. The table below the map also displays each station's wind chill, temperature, and wind data in sortable columns. Since these are the two ingredients for the wind chill, it tells the complete story. The map defaults to the current wind chill but also has a selection at the top where you can change the map to view temperature and wind speed/direction. To calculate the wind chill factor, you can use the following formula: Wind Chill 35.74 + 0.6215T 35.75 (V0.16) + 0.4275T (V0.16) Where: T is the temperature in degrees Fahrenheit. It can also be accessed via the menu in the top left (Menu à Weather à Wind Chill) Calculate the wind chill factor for a temperature of minus 10 degrees Fahrenheit and a wind speed of 55 miles per hour. The Kansas Mesonet makes viewing the wind chill very easy! We have put together a webpage depicting the current wind chill via a gradient map here. Wind chill chart from the National Weather Service. ![]() Wind chills can be determined by the following chart from the National Weather Service ( ):įigure 1. It will be late for the emergency teams if they will arrive after 30 minutes. Since the frostbite times is 5minutes only, then that means it will only take 5 minutes before frostbite happens. Exposure time estimations of frostbite issues at 0 degrees F with no wind is 30 minutes, while 0 oF and 55 mph winds are less than 10 minutes of exposure. Knowing that the wind chill is -60 ☏, we can see from the chart that it belongs to violet portion which means 5 minutes. This colder “feels like” temperature can make you feel chilled quicker and lead to other problems such as frostbite much quicker. This means that despite it being 0 oF on a very cold morning when factoring in the wind (for example, 20 mph), it can feel like a much colder temperature (in this example, -22 oF). Wind chill values decrease as the wind increases and/or the temperature decreases. Wind chill can be calculated in two ways: 1) using the chart below or 2) mathematically. When temperatures drop below 50 oF and wind speeds are greater than five mph, the “Feels Like” temperature is lower than the actual temperature. WIND CHILL CHART V wind speed measured 10 metres above ground level 10 The cooling sensation caused by the combined effect of temperature and wind is called wind chill. The “feels like” temperature is also usually influenced by the wind. However, the temperature does not always give the air that nip. Wind Speed at 10m (33ft): mph knots m/sec km/h. The forecast for the coming week consists of bitter cold air, the coldest of the 2023/2024 winter season thus far.
