Forecast Discussion:

I'll save you a bit of time today by keeping it short... we are in the "very quiets" before a pattern change that is at least 7 days off in the future (or more).  The surface map (Figure 1) shows our back door front that is sitting down the axis of the Rockies and just as far south as northern New Mexico. The upper air map shows the jet stream flow is very flat with just small ridge and trough ripples in the flow (Figure 2).  Nothing is creating much weather.

Figure 2: 500mb upper air analysis forecast map for Friday PM.

In the longer range forecast:

By Sunday - we see some more warbling in the flow, but a ridge is basically sitting over Colorado - so quiet and moderate weather will just continue!
