DayCAST: Wed 10/18/17

One reason for the recent stretch of quiet and warm weather in Colorado is that the position of jet stream is FAR to our north in Canada. Weather systems tend to form near the jet stream….along the baroclinic boundary between warm and cold air masses. Without the jet, our pattern has been quiet this week and this will continue through Friday evening.

250 mb wind map for this afternoon showing the position of the jet stream (lime green).

For today, expect mid-level clouds to dominate the sky in the morning as a swath of elevated moisture interacts with the terrain. However, drier air aloft moves in by lunch which will allow for sunshine this afternoon and evening. High temperatures will be in the upper 70’s today!

After 70’s tomorrow and possibly low 80’s on Friday, a dry cold front sweeps through Friday night. Temperatures will tumble about 20 degrees for Saturday, but at least that sun won’t stop shining…
