Best guess forecast:
Increasing clouds with little temperature change.
Chance of furries
Kananskis is a multi-use natural area 50 km west of Calgary, Alberta. Hikers, cattle, loggers and gas wells share the same territory. Hope you enjoy the weathercam.

The webcam image above uses a telephoto lens that shows a small part of the sky above Kananaskis. If there is snow on the tree branches, that is recent snow. The snow base on the ground is not visible in this image. Sky conditions in Bragg Creek are often different from those shown in this image.

How it works
The weather report uses a Davis Instruments Vantage Pro2 weather station, a security system video camera and TinCam webcam capture software to capture and upload the mountain photo. This page is assembled using Weatherlink software that captures the weather data, updates the web page and uploads the page to the braggcreek.ca web server every 15 minutes.
The barometric pressure is reported in hectopascals (hPa). The forecast uses this and the other data collected by the weather station to estimate the weather forecast. There are no meteorologists or satellites involved. Really it's just a guess.
The temperature at which dew begins to form. During the summer, the dewpoint temperature -- not the relative humidity -- is usually a better measure of how humid it feels outside. High dew points occur in the tropics (Equator) and low dew points are found in deserts and polar areas.
Our weird weather
Chinook winds are westerlies from the Pacific. The moisture in the air precipitates as it passes over the Rocky Mountains. Once these winds come down from the mountains onto the foothills, they can be quite mild and extremely dry - as warm as 15 Celsius with a relative humidity of 10% or less. The air is so dry that when it hits a snowpack, the frozen water evaporates, going directly from the ice to vapour and bypassing the liquid phase entirely. This is called sublimation, and it's a common way for snow to disappear in the arid West." Desublimation occurs when water vapour turns to ice as snow or frost.
